Introduction
Goat milk has been consumed in many forms throughout history in
many dierent cultures, prized for its nutritional prole and digestibility,
and used directly and indirectly through products including cheeses,
yogurts, and buer. Its unique matrix of protein structures and smaller fat
globules make it a viable option for those who are intolerant to cow's milk.
Goat milk is a dietary staple in many parts of the world and is praised not
only for its versatility but also its potential health benets.
Understanding these nutritional proles is essential for consumers
to make informed dietary choices. Factors such as protein quality, fat
composition, vitamin and mineral content, and digestibility play
signicant roles in how each type of milk supports health. At the same
time, the increasing awareness of lactose intolerance and milk allergies has
prompted many to explore alternatives to conventional cow milk, leading
to a rise in the popularity of goat, sheep, and other animal milks.
When comparing bualo milk to goat milk, the laer again shines in
terms of digestibility. Goat milk's lower fat content and dierent protein
composition make it more suitable for individuals who may nd bualo
milk too rich or dicult to digest. Yet more, goat milk's naturally occurring
prebiotics can support gut health, which is an added benet for many
consumers. While bualo milk may oer more fat and protein, goat milk
provides a lighter, potentially more digestible alternative.
Instantaneous, the unique biochemical compounds found in goat
milk, including short-chain fay acids, bioactive peptides, and
antioxidants, contribute signicantly to its suitability for a range of
unconventional derivatives. These compounds not only enhance its
nutritional prole In the same way open doors for innovative applications
across various industries, from food production to health and wellness
sectors.

In this book the authors provide a comprehensive review of the
evolution of processing methods in the dairy industry. By examining
traditional techniques, industrial advancements, and modern innovations,
we aim to highlight the historical context that has shaped dairy processing
as we know it today. This exploration will oer insights into the ongoing
developments and future trends that continue to inuence this vital sector
of the food industry.
In this sense, the general principle of processing methods in goat's milk
are the same as those used in cow's milk, which consist of reducing the
pH and activity of water to prolong its shelf life. The acid gel of goat's milk
is characterized by rmness and lower viscosity compared to cow's and
sheep's milk. The foundation of quality assurance in goat milk processing
begins with stringent hygiene and sanitation practices. Maintaining a
clean environment is crucial for preventing the introduction of pathogens
and contaminants into the milk supply. This involves regular cleaning
and sanitization of equipment, milking facilities, and storage areas.
Throughout the book, four chapters are explored; chapter I discerns
the biological, chemical and nutritional composition of goat's milk and
industrialized processes for processing its derivatives. In chapter II, the
impact of microbial biotechnology on agriculture and health and the role
of enzymes in biological reactions; in chapter III, non-conventional goat
milk derivatives from artisanal to mass production are discussed and
various chemical-industrial techniques and methods for obtaining lactose
proteins, such as ultraltration, are envisioned. The use of acids as
catalysts in protein precipitation and the use of heat treatments have also
been feasible, the laer being the oldest process used for recovery.
Chapter IV outlines a detailed treatment of lactic ferments and
compilations of international standards, e.g. organizations such as the
Codex Alimentarius Commission, established by the World Health
Organization (WHO) and the Food and Agriculture Organization (FAO).
Therefore the research objective: To examine the chemical, biological
and industrial processes for the synthesis of pasteurized goat milk and
10
conventional or unconventional derivatives, with emphasis on FAO and
WHO regulations and recommendations. Therefore, it is important that
the cheese industry has a portfolio of options to use whey as a food base,
preferably for human consumption, in order not to pollute the
environment and to recover, by far, the monetary value of whey, with the
manufacture of whey powders, concentrated sweetener syrups for the
food industry. The authors recommend the scientic community to
complement the research presented in this book with local norms and
regulations according to the type of derivative to be processed from goat
milk and emphasize the importance of the agro-industrial processes
presented in the book.

Chapter I
Chapter 1: The Unique Composition of Goat Milk:
Innovations in Dairy Processing Methods
1.1 Goat Milk vs. Cow and Other Animal Milks: A Comprehensive
Nutritional Comparison
Animal milk has long been a fundamental component of human diets
across cultures and continents, prized not only for its taste likewise for its
rich array of nutrients. The consumption of milk from various animals—
such as cows, goats, sheep, bualo, and camels—oers a diverse spectrum
of nutritional benets, each with unique proles to cater to dierent
dietary needs and preferences.
Understanding these nutritional proles is essential for consumers to
make informed dietary choices. Factors such as protein quality, fat
composition, vitamin and mineral content, and digestibility play
signicant roles in how each type of milk supports health. At the same
time, the increasing awareness of lactose intolerance and milk allergies has
prompted many to explore alternatives to conventional cow milk, leading
to a rise in the popularity of goat, sheep, and other animal milks (Walzem
et al., 2002).
When comparing the nutritional proles of goat milk and cow milk,
several key factors must be considered, including protein content and
quality, fat composition and digestibility, as well as the vitamins and
minerals present in each type of milk. This analysis highlights the distinct
advantages and characteristics of goat milk in relation to cow milk.
Both goat milk and cow milk are excellent sources of protein, essential
for growth, repair, and overall health. Still, the protein structure in goat
milk diers signicantly from that of cow milk. Goat milk contains a higher
proportion of short and medium-chain fay acids, enhancing protein
digestibility (Bendtsen et al., 2013). Therefore, the casein proteins in goat
12
milk form a softer curd compared to the rmer curd formed by cow milk
proteins. This characteristic may contribute to easier digestion, particularly
for individuals with sensitive stomachs.
In terms of overall protein content, cow milk typically has a slight edge,
providing approximately 8 grams of protein per cup, while goat milk
intentions around 7 grams. Nonetheless, the bioavailability of protein in
goat milk may be more advantageous for certain individuals, especially
those with gastrointestinal sensitivities.
Fat content is another critical area of comparison between goat milk
and cow milk. Goat milk has a higher fat content, averaging around 4.5%
to 5% fat compared to 3.5% to 4% in cow milk. Although, the primary type
of fat in goat milk is medium-chain triglycerides (MCTs), which are more
easily absorbed and metabolized by the body. MCTs have been associated
with various health benets, including improved energy levels and weight
management.
Yet more, the fat globules in goat milk are smaller and more easily
digestible than those found in cow milk. This can be particularly benecial
for individuals who experience diculty digesting dairy products, as
smaller fat globules may lead to less gastrointestinal discomfort and
enhanced nutrient absorption.
Goat milk is known for its rich nutrient prole, containing a variety of
essential vitamins and minerals. It is particularly high in calcium,
phosphorus, and potassium, which are vital for bone health and overall
bodily functions. Goat milk also contains higher levels of certain vitamins,
such as vitamin A and vitamin B6, compared to cow milk.
On the other hand, cow milk is often fortied with vitamin D in many
countries, crucial for calcium absorption and bone health. While goat milk
does not naturally contain as much vitamin D, it recommends a wealth of
other nutrients that contribute to a balanced diet. In sudden, while both
goat milk and cow milk provide essential nutrients, goat milk
distinguishes itself through its unique protein structure, digestibility, and
13
an array of vitamins and minerals. Understanding these dierences can
help consumers make informed choices based on their dietary needs and
preferences.
1.1.1 Comparative Analysis with Other Animal Milks
In the realm of dairy products, goat milk often garnishes aention
for its unique nutritional prole and potential health benets. Anyway, it
is essential to compare goat milk not only with cow milk not only with
other types of animal milks, including sheep, bualo, and camel milk. This
analysis will shed light on the distinct advantages and disadvantages of
these various milks, helping consumers make informed dietary choices.
Sheep milk is another popular alternative to cow milk, particularly
in Mediterranean diets. When comparing sheep milk to goat milk, the fat
content is a notable dierence; sheep milk contains a higher fat percentage,
contributing to its creamier texture and richer avor. Nutritionally, sheep
milk is also higher in vitamins A, B12, and D, as well as calcium and zinc,
making it a potent source of essential nutrients (Moatsou and Sakkas,
2019).
Although, goat milk has its own advantages. It tends to be easier to
digest due to smaller fat globules and a dierent protein structure, which
can be benecial for individuals sensitive to cow milk. Also, goat milk
contains higher levels of certain benecial fay acids, such as capric and
caprylic acids, which may have antimicrobial properties. While both milks
are nutritious, the choice between sheep and goat milk often comes down
to personal taste and dietary requirements.
Bualo milk is another alternative that stands out for its rich
nutritional prole. It contains about 50% more fat than cow milk,
contributing to its creamy consistency and making it ideal for producing
rich dairy products like mozzarella cheese. Bualo milk is also higher in
protein and calcium, making it a nutrient-dense option for those looking
to boost their intake of these essential nutrients (Bendtsen et al., 2013).
14
When comparing bualo milk to goat milk, the laer again shines in
terms of digestibility. Goat milk's lower fat content and dierent protein
composition make it more suitable for individuals who may nd bualo
milk too rich or dicult to digest. Yet more, goat milk's naturally occurring
prebiotics can support gut health, which is an added benet for many
consumers. While bualo milk may oer more fat and protein, goat milk
provides a lighter, potentially more digestible alternative.
Camel milk has gained aention in currently for its unique health
benets and nutritional prole. It is lower in fat than both cow and goat
milk while being rich in vitamins and minerals, particularly vitamin C and
iron (Almasri et al., 2024). As a choice, the most signicant advantage of
camel milk is its potential therapeutic properties, particularly for
individuals with diabetes. Research suggests that camel milk may help
regulate blood sugar levels, making it an aractive option for those
managing this condition.
In comparison to goat milk, camel milk is also noted for its
hypoallergenic properties, containing a dierent type of casein protein that
may be less likely to trigger allergic reactions. However, it is important to
note that camel milk can be more expensive and less widely available than
goat or cow milk, which may limit its accessibility for some consumers.
In hasty, while goat milk holds its ground as a nutritious choice, it is
essential to consider the benets and drawbacks of other animal milks,
such as sheep, bualo, and camel milk. Each type of milk bids a unique set
of nutritional characteristics and health benets, allowing individuals to
select the option that best aligns with their dietary preferences and health
needs.
1.1.2 Health Benets and Considerations of Goat Milk
Goat milk has garnered aention not only for its unique avor and
versatility in culinary applications similarly to its potential health benets.
Understanding these benets, along with the considerations surrounding
its consumption, can help consumers make informed dietary choices. In
15
particular, the most notable advantages of goat milk are its potential
suitability for individuals who are allergic to cow milk or who suer from
lactose intolerance. Goat milk contains a dierent protein structure than
cow milk, particularly in regard to casein, which may result in fewer
allergic reactions. Some studies suggest that the proteins in goat milk could
be less allergenic, making it a viable alternative for those sensitive to cow
milk proteins.
Goat milk has a lower lactose content compared to cow milk, although
it is not lactose-free. Many people who are lactose intolerant nd they can
tolerate goat milk beer than cow milk due to the smaller fat globules in
goat milk, which may facilitate easier digestion. Still, individuals with
severe lactose intolerance should approach goat milk cautiously and
consult healthcare professionals before making dietary changes milks
(Walzem, 2004).
The nutritional prole of goat milk makes it particularly appealing
for certain populations, including children and the elderly. For children,
especially those with allergies to cow milk, goat milk can provide a rich
source of essential nutrients such as calcium, phosphorus, and vitamins A
and D, which are crucial for growth and development.
For the elderly, the digestibility of goat milk is a signicant benet.
As individuals age, their digestive enzymes may become less ecient,
making it harder to break down certain foods. The smaller fat molecules
and dierent protein structure in goat milk can ease digestion, potentially
aiding in nutrient absorption. In turn, its high calcium content supports
bone health, a critical concern for older adults.
Beyond its health benets, goat milk is celebrated for its culinary
versatility. It can be used in a variety of dishes, ranging from cheeses like
chèvre and feta to yogurt and ice cream. The distinct avor of goat milk
can enhance recipes, providing a creamy texture and unique taste that
appeals to many palates (Donkor et al., 2007). Goat milk products have
gained popularity across various cuisines worldwide, particularly in
Mediterranean, Middle Eastern, and African cultures. The growing trend
16
toward sustainable and alternative sources of dairy has besides fueled the
demand for goat milk, as many consumers seek to incorporate fewer
common milks into their diets.
Immediate, while goat milk presents several health benets and
culinary possibilities, it is essential to consider individual dietary needs
and potential allergies. As always, consulting healthcare professionals
when making signicant dietary changes is advisable, especially for those
with existing health conditions.
The comparative analysis of goat milk versus cow milk and other
animal milks reveals distinct nutritional proles that cater to varying
dietary needs and preferences. Goat milk stands out with its higher protein
content and superior digestibility, making it an excellent alternative for
those who may struggle with cow milk. Its unique fat composition, rich in
medium-chain fay acids, aids in easier absorption and may contribute to
various health benets.
When examining the vitamin and mineral content, goat milk
advances a robust prole of essential nutrients, including higher levels of
calcium, phosphorus, and certain B vitamins compared to cow milk. This
positions goat milk as a particularly benecial option for individuals
looking to enhance their nutrient intake. Including, comparing goat milk
with other animal milks, such as sheep, bualo, and camel milk,
underscores goat milk's versatility and uniqueness (Almasri et al., 2024).
Each type of milk has its own set of advantages; for instance, sheep milk is
richer in fat and protein, while camel milk boasts unique immunological
properties.
The health benets of goat milk are especially relevant for
individuals with lactose intolerance or milk allergies, as it tends to provoke
fewer allergic reactions and is often beer tolerated (Moatsou and Sakkas,
2019). Now then, its nutritional prole makes it an appealing choice for
children and the elderly, who may require easily digestible sources of
nutrition.
17
In the culinary realm, goat milk's distinct avor and versatility have
contributed to its growing popularity in various cuisines worldwide. From
cheeses to beverages, their applications are broadening, reecting a shift in
consumer preferences toward alternative dairy options.
Overall, goat milk emerges as a commendable source of nutrition,
oering unique advantages over cow and other animal milks. As dietary
choices continue to evolve, understanding the nutritional insights of
dierent types of milk will empower consumers to make informed
decisions that best suit their health and lifestyle needs.
1.2 Unlocking the Biochemical Potential of Goat Milk: A Deep Dive
into Its Unique Components and Innovative Applications
Goat milk has garnered signicant aention in recent years, not only
for its nutritional benets but also for its unique biochemical properties
that dierentiate it from cow's milk and other dairy products. As
consumers increasingly seek alternatives to traditional dairy,
understanding the biochemical components of goat milk becomes essential
in exploring its potential for various unconventional derivatives.
Biochemical properties refer to the specic chemical compounds and
structures present in a substance that contribute to its functional
characteristics and health benets. In the case of goat milk, these properties
are inuenced by factors such as the breed of the goat, its diet, and the
conditions under which the milk is produced. This chapter delves into the
distinct biochemical components of goat milk, highlighting how these
aributes enhance its nutritional prole and make it a suitable candidate
for innovative applications in food, cosmetics, and health products.
Goat milk is rich in essential nutrients, including a unique
combination of fats, proteins, vitamins, and minerals. Anyway, its true
potential lies in the presence of specic bioactive compounds that oer
numerous health benets. From short-chain fay acids that promote
digestive health to bioactive peptides that may possess antimicrobial
18
properties, goat milk is a treasure trove of biochemical constituents that
can be harnessed for a variety of uses.
Goat milk, often regarded as a nutritious alternative to cow's milk,
boasts a unique nutritional prole that is increasingly drawing aention

composition not only makes it palatable for many who are lactose
intolerant. In the same way provides a wealth of nutrients essential for
overall health. Understanding the nutritional composition of goat milk is
crucial for exploring its potential in unconventional derivatives.
1.2.1 Fat Content and Types
One of the dening characteristics of goat milk is its fat content,
which typically ranges from 3.5% to 4.5%. This fat is composed of a higher
proportion of medium-chain fay acids (MCFAs) compared to cow's milk,
making it easier to digest and metabolize. MCFAs, such as caprylic and
capric acid, are known for their quick absorption and energy-boosting
properties. Accordingly, the fat globules in goat milk are smaller and more
uniformly dispersed, which contributes to its creamy texture and enhances
the absorption of fat-soluble vitamins. The unique fat prole not only
aects the sensory qualities of goat milk apart from it opens doors for
innovative products, particularly in the realm of functional foods and
beverages.
1.2.2 Protein Prole and Quality
Goat milk is also distinguished by its protein composition, which
includes a higher proportion of essential amino acids compared to cow's
milk. The primary proteins in goat milk are casein and whey, with the
former being more prevalent. Goat milk contains a specic type of casein
known as A2 beta-casein, which has been associated with improved
digestibility and reduced allergic reactions in some individuals. The whey
proteins present in goat milk, such as lactoglobulin and lactalbumin, are
rich in bioactive peptides that may oer health benets, including
antimicrobial and immunomodulatory eects. This high-quality protein
19
prole makes goat milk an aractive option for those seeking dietary

notion that goat milk can serve as a foundation for creating a diverse range
of unconventional derivatives, from fortied foods to dietary supplements.
In extraction, the nutritional composition of goat milk—
characterized by its distinct fat content, high-quality protein prole, and
abundant vitamins and minerals—positions it as a valuable resource for
innovative applications. As we delve deeper into the unique biochemical
compounds that set goat milk apart, it becomes evident that its nutritional
aributes are not just benecial for direct consumption similarly hold
promise for the development of unconventional derivatives.
1.2.4 Unique Biochemical Compounds in Goat Milk
Goat milk is not only valued for its nutritional benets purely for its
unique biochemical compounds that contribute to its versatility and appeal
in various applications. Understanding these distinct components can
provide insight into why goat milk is increasingly recognized for
unconventional derivatives.
In precise, standout features of goat milk is its higher concentration
of short-chain fay acids (SCFAs) compared to cow milk. SCFAs, such as
butyric acid and caproic acid, are known for their potential health benets,
20
including antimicrobial properties and their role in gut health. These fay
acids are rapidly absorbed and metabolized by the body, making them a
valuable source of energy. Even more, the presence of SCFAs can enhance
the avor prole of goat milk, making it an excellent candidate for
specialty products in the culinary world. Their unique properties also pave
the way for goat milk to be utilized in functional foods aimed at promoting
digestive health.
Bioactive peptides derived from goat milk have garnered aention
for their potential health-promoting properties. These peptides are
produced during the digestion of milk proteins and have been shown to
exhibit various biological activities, including antihypertensive,
antimicrobial, and immunomodulatory eects. The unique protein
composition of goat milk, particularly its casein and whey proteins,
contributes to the bioavailability of these peptides (Bendtsen et al., 2013).
As a result, goat milk can serve as a functional ingredient in health-focused
products, such as dietary supplements and fortied foods, aimed at
improving overall wellness.
Goat milk is also rich in antioxidants and immunoglobulins, which
play crucial roles in supporting immune function and combating oxidative
stress. Antioxidants, such as selenium, vitamin E, and various phenolic
compounds, help protect cells from damage caused by free radicals,
promoting overall health and longevity. Immunoglobulins, particularly
IgG, are antibodies that can enhance the immune response and provide
protection against infections. The presence of these compounds makes goat
milk an aractive option not only for health-conscious consumers similarly
for the development of functional foods and supplements aimed at
enhancing immunity and reducing the risk of chronic diseases.
Instantaneous, the unique biochemical compounds found in goat
milk, including short-chain fay acids, bioactive peptides, and
antioxidants, contribute signicantly to its suitability for a range of

several innovative domains.
Fermented products made from goat milk have gained popularity due
to their enhanced digestibility and probiotic benets. The fermentation
process transforms the lactose in goat milk into lactic acid, which not only
reduces lactose content among which enriches the milk with benecial
bacteria. Products such as goat milk yogurt and ker are noted for their
creamy texture and tangy avor, appealing to a broad audience milks
(Walzem, 2004). To the maximum, the presence of short-chain fay acids
in goat milk promotes gut health, making these fermented products
particularly aractive for individuals with lactose intolerance or sensitive
digestive systems. The probiotic strains found in these products also
contribute to improved immune function, farther solidifying goat milk's
role in health-conscious diets.

Fermentation is a metabolic process that converts sugars into acids,
gases, or alcohol in the absence of oxygen. This process is primarily carried
out by microorganisms such as yeasts and bacteria, which utilize anaerobic
pathways to extract energy from organic compounds (Vilaplana, 2015).
Fermentation serves as an alternative to aerobic respiration, allowing
organisms to generate ATP (adenosine triphosphate) in low-oxygen
environments. The fundamental principle behind fermentation is the
breakdown of glucose through a series of enzymatic reactions, leading to
the production of byproducts such as ethanol, carbon dioxide, and organic
acids.
There are several distinct types of fermentation, each characterized
by the specic microorganisms involved and the end products generated.
The two most notable forms of fermentation are:
a. Alcoholic Fermentation: This type is primarily conducted by yeast,
particularly (Saccharomyces cerevisiae). During alcoholic
fermentation, glucose is converted into ethanol and carbon dioxide.
This process is widely utilized in the production of alcoholic
beverages like beer and wine, as well as in baking, where the carbon
dioxide produced causes dough to rise.
b. Lactic Acid Fermentation: This form of fermentation is performed

for various applications in biotechnology, medicine, and industrial
processes.
2.2.2 Role of Enzymes in Biological Reactions
Enzymes play a pivotal role in facilitating biochemical reactions by
lowering the energy required for these reactions to occur. Each enzyme is
highly specic to its substrate—the molecule upon which it acts—allowing
for precise control over metabolic pathways (Robinson, 2015). For example,
the enzyme amylase catalyzes the breakdown of starch into sugars, while
lactase is responsible for the hydrolysis of lactose into glucose and
galactose. This specicity is essential for maintaining the delicate balance
of metabolic processes within cells.
In addition to catalyzing reactions, enzymes regulate metabolic
pathways by acting as checkpoints. In response to varying cellular
conditions, enzymes can be activated or inhibited, thereby inuencing the
overall metabolic activity of the organism. This regulatory function is vital
for processes such as energy production, DNA replication, and the
synthesis of biomolecules. Several factors inuence the activity of enzymes,
including temperature, pH, substrate concentration, and the presence of
inhibitors or activators.
a. Temperature: Enzymes typically have an optimal temperature range
within which they function most eciently. Higher temperatures
can increase reaction rates to a point, but excessive heat can denature
42
enzymes, leading to loss of function. Conversely, low temperatures
can slow down enzyme activity.
b. pH: Each enzyme has an optimal pH at which it operates best.
Deviations from this pH can result in decreased activity or
denaturation. For instance, pepsin, an enzyme found in the stomach,
operates optimally in acidic conditions, whereas trypsin in the small
intestine functions best in a more alkaline environment.
c. Substrate Concentration: The rate of enzymatic reactions increases
with substrate concentration up to a certain point. Once all active
sites of the enzyme molecules are occupied, the reaction rate levels
o, reaching a maximum velocity (Vmax). This phenomenon is
described by the Michaelis-Menten kinetics.
d. Inhibitors and Activators: Inhibitors are molecules that decrease
enzyme activity, either by blocking the active site or altering the
enzyme's structure. Conversely, activators enhance enzyme
function. Understanding these interactions is essential for
developing drugs and therapies that target specic enzymatic
pathways.
2.2.3 Applications for Enzymes in Biotechnology and Medicine
Enzymes have found extensive application in various elds,
particularly in biotechnology and medicine. In biotechnology, enzymes are
utilized in processes such as biofuel production, where cellulases break
down plant biomass into fermentable sugars. In the food industry,
enzymes like proteases and lipases are employed to improve the texture
and avor of products.
In medicine, enzymes are crucial for diagnostic tests and therapeutic
applications. To illustrate, enzymes such as glucose oxidase are used in
blood glucose monitoring devices for diabetes management. Enzyme
replacement therapies have been developed for genetic disorders caused
by enzyme deciencies, such as Gaucher's disease and Fabry disease.
In this regard, enzymes are pivotal in the development of
biopharmaceuticals, where recombinant DNA technology allows for the
43
production of human enzymes for therapeutic use. This has led to
signicant advancements in treating conditions ranging from cloing
disorders to certain cancers.
As a consequence, enzymatic reactions are integral to life and have
diverse applications that extend beyond natural biological processes.
Understanding how enzymes function and the factors that inuence their
activity is essential for harnessing their potential in various scientic and
industrial elds.
2.2.4 Microbial Biotechnology

optimized using microbial cultures to produce a variety of
bioproducts, including antibiotics, enzymes, and biofuels.
44
Controlling parameters such as temperature, pH, and nutrient
availability is crucial for maximizing productivity.
c. Bioprocessing: This technique focuses on the design and execution
of processes involving living cells or components derived from
them. Bioprocessing is essential in the production of
biopharmaceuticals, where specic microbes are cultured under
controlled conditions to produce therapeutic proteins or vaccines
(Bendtsen et al., 2013).
d. Metagenomics: By analyzing genetic material obtained directly
from environmental samples, metagenomics allows researchers to
explore the diversity and functionality of microbial communities.
This technique has signicant implications for understanding
ecosystem dynamics and discovering novel bioactive compounds.
e. Bioinformatics: The integration of computational tools in microbial
biotechnology helps in analyzing large datasets generated from
genomic and proteomic studies. Bioinformatics aids in identifying
potential microbial strains for application in various
biotechnological processes.
2.2.5 Impact of Microbial Biotechnology on Agriculture and Health
Microbial biotechnology has made substantial contributions to both
agriculture and health, addressing all critical objections faced by these
sectors.
a. Agricultural Applications: Microbial biopesticides and
biofertilizers are increasingly used to promote sustainable farming
practices. Benecial microbes can enhance soil fertility, suppress
plant diseases, and improve crop resilience to environmental
stresses. For instance, nitrogen-xing bacteria play a crucial role in
enriching soil nutrient content, reducing the need for synthetic
fertilizers and minimizing environmental impact (Vilaplana, 2015).
b. Health and Medicine: The pharmaceutical industry has beneted
from microbial biotechnology, particularly in the production of
antibiotics, vaccines, and probiotics. Microorganisms are used to
45
produce life-saving medications, such as penicillin and insulin.
Then, probiotics derived from benecial bacteria support gut health
and contribute to overall well-being.
c. Environmental Remediation: Microbial biotechnology also plays a
vital role in bioremediation, where specic microbes are employed
to degrade pollutants in soil and water. This process can eectively
clean up oil spills, heavy metal contamination, and other hazardous
waste, contributing to environmental sustainability.
In synopsis, microbial biotechnology is a dynamic eld that harnesses
the power of microorganisms to drive innovation across agriculture,
health, and environmental management. By understanding and
manipulating microbial processes, researchers are paving the way for
sustainable solutions to some of the world's most pressing issues.
In abridgement, biological processes such as fermentation, enzymatic
reactions, and microbial biotechnology play a pivotal role in numerous
aspects of life and industry. We have explored the fundamental principles
of fermentation, highlighting its various types—such as alcoholic and lactic
acid fermentation—and its extensive applications in the food and beverage
industries. The signicance of enzymatic reactions has also been
underscored, illustrating how enzymes are crucial catalysts in biological
systems, with their activity inuenced by various factors and their
applications ranging from biotechnology innovations to medical
advancements.
Moreover, the realm of microbial biotechnology showcases the
profound impact that microorganisms have on agriculture and health,
driven by sophisticated techniques that harness their capabilities for
benecial purposes (Zhou and Sun, 2010). This eld continues to expand,
oering promising solutions to global deance, including food security
and disease management.
Looking ahead, the study of biological processes is set to evolve besides,
fueled by advancements in technology and our increasing understanding
of biological systems. Future research may uncover new applications and
46
enhance existing processes, leading to breakthroughs that could transform
industries and improve quality of life.
Hence, the signicance of biological processes cannot be overstated;
they are integral to both natural ecosystems and human endeavors. As we
deepen our understanding of these processes, we open doors to innovative
applications that could shape the future of medicine, agriculture, and
environmental sustainability.
2.3 Exploring Unconventional Dairy Derivatives: The Health
Benets of Ker, Probiotic Cheese, and Lactose-Free Products
Nowadays, the landscape of dairy consumption has evolved
signicantly, driven by an increasing awareness of health, dietary
restrictions, and the quest for enhanced nutritional benets.
Unconventional dairy derivatives—such as ker, probiotic cheese, and
lactose-free products—have emerged as innovative alternatives that cater
to diverse dietary needs and preferences.
As more individuals turn to these unconventional options, it is
crucial to understand their signicance in modern nutrition. For many,
lactose intolerance poses a barrier to enjoying traditional dairy, prompting
the development of lactose-free alternatives that allow everyone to benet
from the nutritional value of dairy products without discomfort (Facioni et
al., 2020). Now then, the rise of probiotic-rich foods reects a growing
appreciation for gut health and the role of probiotics in supporting overall
well-being.
In this regard, integrating these unconventional dairy derivatives
into daily diets aligns with contemporary health trends that emphasize
functional foods that oer health benets beyond basic nutrition. By
exploring the various options available, from the tangy taste of ker to the
creamy richness of probiotic cheese, consumers can make informed choices
that enhance their diets and promote a healthier lifestyle.
Ker is a tangy, eervescent fermented dairy product that has
gained popularity worldwide for its distinctive avor and numerous
47
health benets. Originating from the Caucasus region, ker has been
consumed for centuries and is recognized for its probiotic properties,
which contribute to gut health and overall well-being.
Ker is a cultured milk beverage produced by fermenting cow, goat, or
sheep milk using ker grains—small, gelatinous clusters of bacteria and
yeast. These grains are rich in probiotics, which are live microorganisms
that provide health benets when consumed in adequate amounts (Zhou
and Sun, 2010). The fermentation process typically takes 12 to 24 hours,
during which the lactose in the milk is converted into lactic acid, giving
ker its characteristic tart avor and creamy texture.
The origins of ker date back to the Caucasus Mountains, where it
was traditionally made by pouring milk into a leather pouch containing
ker grains. The unique environment and culture of the region contributed
to the development of this probiotic-rich beverage. Today, ker is enjoyed
in various forms across the globe, from plain to avored varieties, and is
increasingly recognized for its health-promoting properties.
Ker is not only a delightful addition to diet, not only a nutrient-
dense food. It is an excellent source of protein, calcium, and vitamins such
as B12 and riboavin. Accordingly, ker contains a wide variety of
probiotics, which can enhance gut health by promoting a balanced
microbiome.
The health benets of ker extend beyond its nutritional content.
Research has shown that regular consumption of ker may improve
digestive health, boost the immune system, and even reduce inammation.
The probiotics found in ker can aid in digestion, alleviate symptoms of
lactose intolerance, and enhance nutrient absorption. At the same time,
ker is associated with potential benets for mental health, as emerging
studies suggest a link between gut health and mood regulation.
Incorporating ker into your diet is simple and versatile. Here are a few
ideas to enjoy this fermented dairy delight:
48
a. Smoothies: Blend ker with fruits, vegetables, and a spoonful of nut
buer for a nutritious and creamy smoothie that packs a probiotic
punch.
b. Dressings and Dips: Use ker as a base for salad dressings or as a
dip ingredient, mixing it with herbs, spices, and garlic for a
refreshing twist.
c. Breakfast Bowls: Pour ker over granola or oatmeal, adding fresh
fruits and nuts for a wholesome breakfast option.
d. Baking: Substitute ker for buermilk or yogurt in baking recipes,
such as pancakes, muns, or cakes, to achieve a tender texture and
enhance avor.
e. Sipping: Enjoy ker straight from the bole as a refreshing beverage
or use it in place of milk in your favorite recipes.
This way, ker is a versatile and nutritious fermented dairy product
that poses a range of health benets. Its unique avor and probiotic content
make it a valuable addition to modern diets, promoting beer digestion
and overall wellness. As we explore unconventional dairy derivatives, ker
stands out as a powerhouse of nutrition and a delightful culinary
ingredient.
2.3.1 Probiotic Cheese: Enhancing Traditional Cheese with
Probiotics
As consumers become increasingly health-conscious, the food
industry has responded with innovative products that merge traditional
favorites with modern nutritional science. One such innovation is probiotic
cheese, which incorporates benecial live bacteria into the cheese-making
process, enhancing both its avor and health benets. Probiotic cheese
comes in various forms, oering options to suit dierent palates and
culinary applications (Araujo et al., 2024):
a. Soft Cheeses: Varieties such as cream cheese, ricoa, and feta often
come with added probiotics. Their creamy textures and mild avors
make them versatile in both savory and sweet dishes.
49
b. Hard Cheeses: Cheeses like cheddar and gouda can also be
produced with probiotics. These cheeses typically have a longer
aging process, enhancing their complex avors while still delivering
the benets of probiotics.
c. Spreadable Cheeses: Many brands oer probiotic-enhanced
spreadable cheeses, ideal for dipping or spreading on crackers and
bread. These varieties often combine avors such as garlic, herbs, or
spices.
d. Plant-Based Probiotic Cheeses: With the rise of veganism, plant-
based dairy alternatives have emerged. Made from nuts, soy, or
coconut, these cheeses can also be infused with probiotics, appealing
to those seeking non-dairy options.
The incorporation of probiotics into cheese not only diversies the
avor prole apart from it oers several health benets:
a. Gut Health: Probiotic cheese contains live cultures that help balance
gut microbiota, crucial for digestive health. This can lead to
improved digestion and reduced gastrointestinal issues.
b. Immune Support: Regular consumption of probiotic-rich foods,
including cheese, may enhance the immune system by promoting
benecial bacteria and inhibiting harmful pathogens.
c. Nutritional Value: Probiotic cheese retains the nutritional benets
of traditional cheese, including protein and calcium, while also
adding the functional benets of probiotics.
d. Enhanced Flavor: The presence of probiotics can contribute to
unique avor proles, enriching the cheese experience. Many
consumers nd probiotic cheeses to have a more complex taste
compared to their non-probiotic counterparts.
Probiotic cheese can be seamlessly integrated into various dishes,
making it a delightful addition to any meal plan. Here are some creative
ways to incorporate it:
50
a. Cheese Plaers: Include probiotic cheeses on charcuterie boards
alongside fruits, nuts, and crackers for a delicious and nutritious
appetizer.
b. Salads: Crumble probiotic feta or add sliced probiotic cheddar to
salads for a avorful protein boost.
c. Sandwiches and Wraps: Spread probiotic cream cheese on whole-
grain bread or tortillas, pairing it with fresh veggies and lean
proteins for a satisfying lunch.
d. Cooking and Baking: Use grated probiotic cheese as a topping for
casseroles, pizzas, or baked pasta dishes to enhance avor while
reaping health benets.
e. Snacks: Enjoy probiotic cheese on its own or with whole-grain
crackers and fresh fruit for a quick, healthy snack.
Incorporating probiotic cheese into your diet not only elevates your
culinary experience apart from it supports your health in multiple ways.
As the demand for functional foods continues to rise, probiotic cheese
represents a delicious and benecial trend in the world of dairy.
2.3.2 Lactose-Free Products: Catering to Lactose Intolerance and
Beyond
Lactose intolerance is a common condition aecting a signicant
portion of the global population. It occurs when the body lacks sucient
levels of lactase, the enzyme required to digest lactose, the sugar found in
milk and dairy products. In response to this widespread issue, the dairy
industry has developed a range of lactose-free products, which not only
cater to those with lactose intolerance among which appeal to individuals
seeking to reduce their dairy intake for various reasons, including health
and dietary preferences.
Lactose-free dairy products are made by treating regular milk with
enzyme lactase, which breaks down lactose into simpler sugars—glucose
and galactose—that can be easily absorbed by the body. This process
results in milk that retains the same taste and nutritional prole as regular
milk but is devoid of lactose. The range of lactose-free products has
51
expanded signicantly and now includes milk, yogurt, cheese, and even
ice cream. These options allow those who experience discomfort after
consuming traditional dairy to enjoy familiar avors and textures without
the associated gastrointestinal distress (Sánchez et al., 2009).
Lactose-free products oer several health benets beyond merely
alleviating symptoms of lactose intolerance. For individuals who are
lactose intolerant, these products enable the consumption of essential
nutrients found in dairy, such as calcium, vitamin D, and protein, without
adverse eects. In perspective, lactose-free dairy products often have
higher digestibility than their traditional counterparts, making them
suitable for individuals with sensitive stomachs or digestive issues.
In this vein, lactose-free products can be benecial for those
managing their overall sugar intake. Since lactose-free milk and yogurt
have lower levels of naturally occurring sugars compared to regular dairy,
they can be a beer choice for individuals monitoring their sugar
consumption for weight management or other health concerns.
2.3.3 Comparing Lactose-Free Products to Traditional Dairy
When examining lactose-free products in comparison to traditional
dairy, several factors come into play. Nutritionally, lactose-free options
closely mirror their conventional counterparts, oering similar levels of
protein, calcium, and other key nutrients. Even so, some lactose-free
products may have a slightly sweeter taste due to the presence of broken-
down sugars, enhancing the avor without adding extra sugars or calories.
In terms of availability, lactose-free products have become
increasingly mainstream, with many grocery stores stocking a variety of
options. This accessibility has made it easier for consumers to make
informed choices that suit their dietary needs. Even more, lactose-free
products often cater to a broader audience, including those who may not
have lactose intolerance but prefer to limit their dairy intake or are looking
for alternatives that are easier on the digestive system.
52
Consequently, lactose-free products serve as a vital component in
the modern dairy landscape, providing a delicious and nutritious
alternative for those with lactose intolerance while appealing to a broader
audience seeking healthier options. With their growing availability and
diverse range, lactose-free products are not only transforming how
individuals approach dairy consumption but are also contributing to
overall dietary health and wellness.
Nowadays, there has been a notable shift in consumer preferences
towards unconventional dairy derivatives, driven by a growing awareness
of health and nutrition. Products like ker, probiotic cheese, and lactose-
free options are not just trendy alternatives; they represent a signicant
evolution in how we approach dairy consumption. As more individuals
become concerned about gut health, lactose intolerance, and the benets of
probiotics, these innovative dairy products are nding their way into
mainstream diets.
Ker, with its rich probiotic content, oers a delicious and nutritious
way to enhance gut health and boost the immune system. Its versatility
allows it to be consumed in various forms, from smoothies to salad
dressings, making it an easy addition to daily meals. Similarly, probiotic
cheeses present an exciting blend of avor and functionality, enriching our
traditional cheese options with added health benets. These cheeses not
only satisfy culinary cravings on the contrary support digestive health,
appealing to both cheese lovers and health-conscious consumers alike.
Lactose-free products have also emerged as a vital category,
providing essential nutrients without the discomfort associated with
lactose intolerance. With an increasing number of people identifying as
lactose intolerant, these products help ensure that everyone can enjoy the
nutritional benets of dairy without adverse eects (Facioni et al., 2020).
By bridging the gap between dietary restrictions and nutritional needs,
lactose-free options are enhancing the inclusivity of modern diets.
So, to embrace a more health-focused approach to eating,
unconventional dairy derivatives will become even more prominent. Their
53
unique health benets, combined with culinary versatility, make them
valuable additions to our diets. In this era of informed eating,
understanding and incorporating these innovative dairy products can lead
to improved health outcomes and a more enjoyable eating experience.
Thus, the relevance of unconventional dairy derivatives is not just a
passing trend; it is a fundamental shift towards a healthier, more inclusive
approach to nutrition in contemporary society.

Chapter III
Non-conventional derivatives of goat's milk
3.1 Whey
Whey or whey is the liquid fraction obtained during the coagulation
of milk in the process of making cheese and casein, after the separation of
the clot, its characteristics correspond to a greenish-yellow liquid, cloudy,
with a fresh taste, weakly sweet. Whey is one of the most polluting
materials in the food industry. Every 1000 liters of whey about 35 kg of
biological oxygen demand (BOD) and about 68 kg of chemical oxygen
demand (COD) are generated. This polluting force is equivalent to that of
sewage produced in one day by 450 people (FAO, 1980).
Whey is dened as a liquid obtained after the precipitation and
separation of casein from milk during cheese production and constitutes
85% - 90% of the volume of milk (González 2010), whose main components
such as lactose, calcium, mineral salts and low molecular weight lacto-
serum proteins soluble at their isoelectric point are retained in 55%. since
they do not react with rennet (Caro et al., 2011).
Whey is a highly diluted product and its organoleptic and
physicochemical characteristics can vary depending on the type of whey
(sweet or acidic) or what is the same type of cheese processing (Aider et al.
2009; Fernández et al. 2009), the source of milk (cow, goat, bualo, sheep,
etc.), the animal's diet, the time of year and the lactation status (Valencia
2009). Previously, this by-product was described as an environmental
pollutant, since when it was discharged into the environment without any
type of treatment to counteract the high content of protein and sugary
components, it had an impact on the quality of the waters, generating high
rates of BOD (Biochemical Oxygen Demand) and COD (Chemical Oxygen
Demand) (FAO 2009).
After various investigations, the mentality of whey has changed,
which is not a whole substitute for cow's milk because it is a fraction of it
55
but contains nutrients and compounds with potential nutritional and
health benets, making it an important component for the manufacture of
other products. There is very lile statistical information on whey
production, which may be basically due to the lack of interest in it and its
use, including the lack of interest in it as a raw (Zhou and Sun, 2010).
Not using whey as food is a huge waste of nutrients; Whey contains
just over 25% of milk proteins, about 8% of fat and about 95% of lactose.
As shown above, at least 50% of the nutrients in milk remain in the whey.
The same 1000 liters of whey referred to above contain more than 9 kg of
protein of high biological value, 50 kg of lactose and 3 kg of milk fat. This
is equivalent to the daily protein requirements of about 130 people and the
daily energy requirements of more than 100 people. Therefore, it is
important that the cheese industry has a portfolio of options to use whey
as a food base, preferably for human consumption, in order not to pollute
the environment and to recover, by far, the monetary value of whey, with
the manufacture of whey powders, concentrated sweetener syrups for the
food industry. (FAO, 1980).
Goat's milk whey (LSLC) is the liquid resulting from the production
of curd or cheese, when casein and fat are separated during coagulation
(about 85-90% of the volume of milk used). It is made up of approximately
93% water, 5% lactose, a lile less than 1% protein, of which half are
proteins of high nutritional value such as; albumins, globulins and
protease-peptone, 0.7% minerals, with a higher content of sodium,
potassium, magnesium, chloride and phosphate, also contains the water-
soluble vitamins of milk, the most important is riboavin, it also has small
amounts of fat and lactic acid (LA) and its pH is between 5-6.
Currently the serum has lile industrial applicability, the surpluses
become a very high pollutant (BOD), from 40000 to 60000 ppm and a
chemical oxygen demand (COD) of 50000 to 80000 ppm. More than 90% of
these demands are due to the transformation of lactose. Hence, the search
for alternatives for the use of this euent becomes a national need. One of
the alternatives is to obtain lactic acid (Plata et al., 2013).
56
Lactic acid is widely used in industry. Due to its characteristics, it is
used in the food industry (in beverages and as a preservative), in
pharmacy, medicine, textiles, in the leather industry and for the production
of biodegradable plastics. One of the main diculties in large-scale
production of LA is the cost of raw materials, and it is of interest to nd
new low-cost means to improve the economics of the process.
The major organisms that produce LA belong to the families
Streptococcaceae (genera Streptococcus, Lactococcus, Leuconostoc,
Pediococcus, Aerobacter and Gemella) and Lactobacillaceae (genus
Lactobacillus). The Lactobacillaceae family and especially those of the
genus Lactobacillus (L. bulgaricus, L. helveticus, L. delbruekii, etc.), are
facultative anaerobes (they do not have surface growth or it is scarce), they
do not have catalase, they do not reduce nitrate; its metabolism is
fermentative, about 50% of its nal product is lactic acid, its optimal
growth temperature is between 30-40°C, in an acceptable range between 26
and 46°C, at a pH of 4.5-7.2 and it is a non-pathogenic microorganism (Plata
et al., 2013).
This by-product of the cheese-making process retains about 55% of
the nutrients of the milk, among which are serum proteins with an
appropriate balance in amino acids, high digestibility and excellent
functional characteristics, which has induced the development of
fractionation processes and concentration of its constituents. In some
countries, the application of fractionation and concentration processes in
the treatment of whey has made it possible to obtain concentrates with a
protein content between 30 and 80%, which are being used for the
enrichment of foods such as bread, soups and beverages, helping to
alleviate protein deciencies caused by excessive population growth. and
due to the scarcity and increase in the price of conventional protein foods
(Tirado et al., 2015).
Whey has signicant protein, fat, lactose and calcium content. In
relation to protein content, the serum proteins in milk are globular, among
them, those present in greater quantities are βlactoglobulin (β-LG) and α-
57
lactalbumin (α-LA) and as minor constituents are lactoferrin,
lactoperoxidase, immunoglobulins and glycomacropeptides, among
others. Although whey, as an abundant and readily available by-product
of the cheese industry, was once considered a waste material, it is now
considered a valuable source of protein and is widely used as a food
ingredient.
Various techniques and methods have been used to obtain lactoseic
proteins, such as ultraltration. It has also been feasible to use acids as
catalysts in protein precipitation and the use of heat treatments, the laer
being the oldest process used for recovery. The food industry, and dairy in
particular, has always been interested in nding new methods for food
preservation in order to improve the hygiene and safety of the nal
product, increase its shelf life and maintain a natural avor in the food
(Tirado et al., 2015).
3.1.1 Types of whey
Depending on the type of coagulation of the casein used in cheese
manufacturing, sweet whey or acidic whey is generated. Sweet whey is
obtained from enzymatic coagulation, with a pH close to that of fresh milk,
which, due to the stability of its composition, is the most widely used in
the industry, unlike acid whey, which results from acid or lactic
coagulation. For Jelen (2003), there are several types of whey depending
mainly on the elimination of casein, the rst called sweet, is based on
coagulation by renin at pH 6.5. The second so-called acid results from the
process of fermentation or addition of organic acids or mineral acids to
coagulate casein as in the production of fresh cheeses. Coagulation occurs
by natural acidication or the addition of organic acids.
On the other hand, González (2010) denes sweet whey as that
obtained by enzymatic coagulation using a rennet of animal origin, such as
calf renin or a microbial rennet of genetic technology. Acid whey is
obtained by the natural acidication of milk or by the fermentation of milk,
due to the bacterial ora existing in it and that obtained by the addition of
acids. Coagulation is mainly caused by chemical and/or bacterial
58
acidication. On the other hand, whey, or whey, sweet is that whey in
which the lactose content is higher and the acidity is lower than that of
acidic whey.
In summary, Pintado et al. (2012) dene sweet whey as the aqueous
phase that is separated from curd in the process of making cheese or casein,
greenish-yellow in color with a pH between 5.8-6.6 and Riera et al. (2004)
acid whey as that produced in dairy industries when coagulation is carried
out with an acid, decreasing the pH value to 5.1. Each of these denitions
are similar in their clarications from their obtaining to the pH range that
are used in each of them, which allows this concept to be clearly explained.
a. Whey technology
Regardless of the subsequent treatment, the rst step is the
separation of the fat and casein nes, as they interfere with the subsequent
steps. Fine casein particles are always present in the whey. These have an
adverse eect on the fat separation process, which is why they must be
separated in the rst place. The whey to be stored, before treatment, must
be cooled or pasteurized as soon as the fat contained in it is separated.
When storage is going to be short (10-15 hours), cooling is sucient to
reduce bacterial activity. If the whey is to be stored for longer periods, it is
necessary to proceed with pasteurization (Kreczmann et al., 2015).
b. Obtaining WPC
Whey protein concentrates are presented as a powder
manufactured by drying the ultraltration concentrate. They are described
in terms of their protein content (percentage of protein over dry maer),
ranging from 35 to 80%. To make a product with 35% protein, liquid whey
is concentrated about six times to a total solids content of approximately
9%. To obtain a concentrate with 80% protein, the liquid whey is
concentrated about 20-30 times by ultraltration to a solids content of
approximately 25%. This value is considered as the maximum for an
economical operation, so it is necessary to dialter the concentrate to
remove lactose and ash and increase the concentration of proteins in
59
relation to the total dry maer. Dialtration (DF) is a process in which
water is added to the food as ltration is carried out in order to wash away
the low molecular weight components that will pass through the
membrane, basically lactose and mineral salts.
This permeate is used as a raw material to obtain lactose. Before the
ultraltration stage, additional treatments, such as demineralization by
nanoltration (NF), can be performed. This is done through the use of
specially designed, very small-pore reverse osmosis membranes, where
small particles such as certain monovalent ions (sodium, potassium,
chloride) and small organic molecules (such as urea and lactic acid) can
escape through the membrane along with the aqueous permeate to obtain
a protein concentrate (WPC) from whey. Most of the pure proteins, usually
more than 99%, are retained in the concentrate, along with the fat content
that was not removed in skimming (Kreczmann et al., 2015).
c. Obtaining WPI
Whey protein isolates can be obtained mainly by two methods:
membrane technology and ion exchange technology. The exchange of ions
provides a higher concentration of protein per kilo of nal product, but this
is only part of the equation that is of interest. Ion exchange isolates, like
many whey concentrates, are processed at high temperatures and therefore
sacrice the biological activity of the micro fractions that exist in whey.
These ion exchange isolates are obtained through a technology called an
"ion exchange column", which separates proteins from the rest of the
components of the serum by discriminating based on their electrical
charge.
During this process, most of the bioactive components, which give
whey protein extra value to promote health and performance, are broken
down or lose their biological capacity altogether. One of the sharpest losses
occurs in the so-called glycomacropeptides (GMP). Instead, ion exchange
isolates manage to increase (Kreczmann et al., 2015). The concentration of
beta-lactoglobulin is alarming, a subfraction that is not at all interesting
since its indiscriminate ingestion is associated with a large number of
60
allergic reactions. Membrane technology uses series stages of ultraltration
(UF) and microltration (MF) to obtain WPI; i.e. the MF permeate
(degreasing) is sent to a second UF unit for further concentration.
This stage also includes dialtration (DF). The microltration
membranes used for this purpose are designed to retain suspended
particles in the micron range, such as fats present in concentrated whey.
On the other hand, the ultraltration membranes used are designed to
retain whey constituents in the molecular range, such as proteins,
separating them from lactose and other impurities present in whey (raw
material for the production of lactose).
It should be noted that treating whey concentrate from ultraltration
in a microltration plant can reduce the fat content of WPC 80-85% powder
from 7.2% to less than 0.4%. This technique diers from ion exchange in
that there is no chemical modication of the proteins and that the
glycomacropeptide fraction is retained along with the others. If there is no
pH adjustment and the process is carried out at intermediate temperatures,
the nal product is almost completely free of denatured proteins
(Kreczmann et al., 2015).
d. Composition of whey
The main components of whey, both sweet and acidic, are water (93-
94%), lactose (70-75% of total solids), serum proteins (8-11% of total solids)
and minerals (10-15% of total solids). It also has fat and vitamins. The
composition of whey depends on the type of cheese (enzymatic or acidic),
the cheese-making techniques used (such as the coagulation method), the
treatment undergone by the liquid whey (heat treatments, pre-
concentration, recovery of casein nes), the physiological state of the
animal, the type of breed and species, and also follows the trend of the
chemical composition of the milk from which it comes (Jelen, 1992).
e. Lactose
Lactose is not only the main carbohydrate in milk, but also the main
component of whey (apart from water), constituting approximately 4.4 -
61
4.9% of total whey (~ 75% of dry extract) (Jelen, 1992). It is a disaccharide
formed by a glucose molecule and a galactose molecule, which is
synthesized in the mammary gland. The concentration of lactose in the
serum is fairly constant, but it depends on the proportion of the original
lactose that has been degraded to lactic acid. Acid whey has a lower lactose
content than sweet whey, and consequently, a high lactic acid content
because during bacterial fermentation part of the lactose is transformed
into lactic acid. It is reducing sugar, which in some circumstances, can react
with the amino groups of proteins.
It is an adequate source of energy that plays an important role in the
absorption of calcium, lactose is characterized by having limited solubility
and low sweetness which limits, on many occasions, its use in food, so it is
usually hydrolyzed before use. Yellowing of serum may occur after
prolonged heat treatment or even by non-enzymatic browning reactions
(Maillard reaction) between lactose and serum proteins (Jelen, 1992).
f. Serum proteins
Although the main component after water is lactose, serum proteins
are the most valuable ingredient (Jelen, 2003). They can be dened as
proteins that remain soluble in the liquid phase after precipitation of
caseins at pH 4. They make up approximately 0.7% of the whey (~8-11% of
the dry extract). In addition, whey also contains 0.2-0.3% non-protein
nitrogen. The protein content of whey depends mostly on the type of clot
and its treatment, and the presence of curd particles in it can increase it
considerably (Sco, 1991). In milk, 80% of the proteins are caseins;
however, these are added to the curd during cheese formation, while
serum proteins are not retained in the curd, remaining dissolved in the
aqueous portion (Walzem et al., 2002).
Serum proteins are even a more heterogeneous group than caseins,
and have few features in common (Robin et al., 1993), exhibiting a number
of unique properties that depend on their molecular weight, composition,
and amino acid sequence.
62
• They are soluble under conditions that are not caseins (at pH
4.6-4.7).
• Most are globular proteins.
• They are easily denatured by heat, while caseins are more
stable.
• Caseins have strong hydrophobic regions while serum
proteins have a greater balance between hydrophilic and hydrophobic
residues.
• They are not greatly aected by pH and salts.
• They are not phosphorylated and are insensitive to calcium.
• They have a more organized secondary and tertiary structure
than caseins due to a more uniform distribution of amino acid types along
the polypeptide chain and the presence of disulde bridges (which implies
that they have large amounts of cysteine unlike what happens in caseins).
All serum proteins contain intermolecular disulde bridges that stabilize
their structure.
One of the most important characteristics of serum proteins is the
high presence of amino acid residues with sulydryl groups that allow
them to form intermolecular covalent bonds during processes at high
temperatures (which causes their denaturation and subsequent
aggregation). Whey proteins are soluble over a wide pH range and are
denatured (individually and in solution) between 64 and 85 °C, and from
this temperature they begin to aggregate and gel. Denaturation involves
the loss of protein solubility. The main serum proteins are β-lactoglobulin
(β-LG), αlactalbumin (α-LA), immunoglobulins (Igs), serum albumin
(BSA) and peptone proteoses. Along with these, other minority proteins
such as glycomacropeptide, lactoferrin, and enzymes such as
lactoperoxidase appear. The dierences found in the protein prole may
be a consequence of seasonal variations, the stage of lactation, the breed,
the diet and the cheese processing techniques used. The dierent heat
treatments applied, both to milk and whey, can also inuence serum
63
proteins, since their heat stability is dierent, and follows this decreasing
order: α-LA > β-LG > BSA > Ig (Morr and Ha, 1993).
g. Lipids
Goat's milk contains 97-99% free lipids and 1-3% lipids bound to
other substances (Park, 2006). Free lipids are made up of triglycerides or
triacylglycerols, diglycerides or diacylglycerols and monoglycerides or
monoacylglycerols, while bound lipids are made up of neutral lipids
(mainly triglycerides) and polar lipids (phospholipids and glycolipids).
Practically all milk fat is found in fat globules, with the average
diameter of fat globules in goat's milk (2.76μm) being smaller than those in
cow's milk (3.51μm). The small size of the globules implies a beer
dispersion and a more homogeneous mixture of the fat in the milk,
although it has a worse ability to skim (Park, 2006). In addition, the fat
globules in goat's milk do not experience coalescence at refrigeration
temperatures due to the absence of agglutinin, which is responsible for the
aggregation of fat globules in cow's milk. Lipids present in serum are
associated with the membrane of the fat globule and phospholipids are the
main lipids of this membrane (Walstra et al., 2006).
However, triacylglycerols are the main lipids in CPS, followed by
phospholipids, diacylglycerols, free fay acids, cholesterol esters,
cholesterol and monoacylglycerols, which may be a consequence of the
presence of small fat globules in the serum. Serum lipid concentration is
low (Walzem, 2004). It is usually 0.5-1%, although it depends on the type
of milk, the type of cheese and the eciency of the cheese manufacturing
process. In most sour cheeses such as coage or quark, the lipid content is
almost negligible because the type of milk used is usually skimmed. (Jelen,
1992).
3.2 Vitamins, minerals and nutritional properties
Minerals make up the third largest component of the total solid
content of whey. Although the salt content is usually quite constant, its
mineral composition varies depending on the type of whey obtained and
64
depends on other factors related to the cheese manufacturing methods
used, especially the addition of sodium chlorides or calcium chlorides to
milk. However, the main dierences between the two types of whey are
due to the dierent way in which caseins coagulate. Acidic sera have a
higher calcium and phosphorus content due to the solubilization of
colloidal calcium phosphate from casein micelles during acidication.
However, in sweet whey, calcium is not separated from the micelles,
so most of the calcium remains retained in the cheese and is not lost in the
whey. Acidic whey is also richer in magnesium and zinc, and citrate. The
main macro minerals in goat's milk are calcium, phosphorus, potassium
and chlorine, with a higher content than in cow's milk, and above all, in
relation to human milk (Sanmartín, 2010; Ballard and Morrow, 2013).
Calcium appears to be important in terms of heat stability, while
sodium and potassium are responsible for the salty taste, and along with
lactose for whey osmolarity. During the processing of the serum, the
concentration of minerals can be altered, as its content can be reduced by
electrodialysis, nanoltration or ion exchange. During ultraltration (UF),
minerals bound to proteins (e.g., calcium, phosphorus, magnesium) are
retained in the membrane and concentrated together with them, while
soluble minerals (sodium, potassium, citrate) pass into the permeate
(Sanmartín, 2010).
Riboavin (B2) is the most abundant vitamin in whey. It is a water-
soluble, heat-stable, and light-sensitive protein. It is responsible for the
greenish color of the serum. It can be retained by reverse osmosis, but not
through UF membranes, so UF permeates can also have this color. Goat's
milk, and therefore whey, has higher amounts of vitamin A than cow's
milk, because the goat converts all β-carotene into vitamin A, while it is
decient in folic acid and vitamin B12 compared to cow's milk. Both milks
are decient in pyridoxine (B6), vitamin C and D. The water-soluble
vitamins that are present in milk remain in whey in varying proportions:
40-70% of vitamin B12, 55-75% of B6 and pantothenic acid, 70-80% of
riboavin and biotin, 80-90% of thiamine, nicotinic acid, folic acid and
65
ascorbic acid. The concentration of vitamin C is reduced during processing,
so why is not considered a good source of this protein. Of all the fat-soluble
vitamins, the most abundant is A. During UF, fat-soluble vitamins are
retained in the concentrate by separating with lipids, while only folic acid
and vitamin B12 are retained from soluble vitamins (Sanmartín, 2010).
Since ancient times, the nutritional value of whey has been
recognized. In 460 BC, Hippocrates recommended drinking considerable
amounts of serum for long periods, because he had observed that it had
therapeutic applications (Jelen, 2003). During the Middle Ages, many
doctors prescribed the serum against various diseases. In the mid-
seventeenth century, whey became the fashionable drink in English cities,
opening numerous "whey houses", analogous to today's "coee shops".
During the nineteenth century, serum baths were very popular in spas
(Tunick, 2008); in the 40s in the spas of Central Europe many diseases, such
as anemia, tuberculosis, arthritis, uremia, etc., were treated with the
ingestion of up to 1.5 kg of serum/daily (Holsinger et al., 1974).
Whey is a good source of bioavailable nutrients, providing high-
quality protein, lactose, minerals, water-soluble vitamins (especially
riboavin), and bioactive components. From a nutritional point of view,
proteins are the main focus of interest because they are an excellent
nutritional source, as they are easily digestible and contain all the essential
amino acids in the right proportions and similar to the proteins of the
human body. Serum proteins have the highest bioavailability of all
proteins, so our body can metabolize them more eciently (Pordesimo and
Onwulata, 2008).
Serum proteins, unlike caseins, pass rapidly from the stomach to the
small intestine during digestion, where they are hydrolyzed more slowly
while their amino acids are absorbed more quickly than amino acids from
caseins. For this reason, serum proteins can be used as emulsiers in food
formulation to decrease intestinal transit time, thereby improving nutrient
digestibility and absorption.
66
They have a high biological value, compared to that of other dietary
proteins, thanks to their high content of essential amino acids (mainly α-
LA and β-LG) and especially lysine, tryptophan, methionine and cysteine).
The high intake of some essential amino acids (lysine, threonine,
methionine and isoleucine) allows whey to be used as a supplement to
vegetable proteins (Walzem, 2004).
Whey has bioactivity, which is aributed to serum proteins and
other nitrogenous compounds (bioactive peptides), which are those
protein fragments obtained by proteolysis after the action of
gastrointestinal enzymes. For peptide to have a biological eect
endogenously, it must be resistant to degradation during intestinal transit
and be able to be transported through the intestinal mucosa resisting the
action of epithelial peptidases. This biological activity has a positive eect
on bodily functions and conditions, and ultimately on health.
Being one of the richest sources of bioactive material, serum proteins
have benets beyond simple nutrition. These eects are, among others,
antimicrobial properties, reduction of cancer cell proliferation, immune
enhancement, reduction of hypertension, antioxidant and antithrombotic
activity, reduction of cholesterol levels, which have benecial eects on
cancer, kidney disease, osteoporosis, obesity. Some of these bioactive
peptides derived from serum proteins are lactoporins and lactorns, from
α-LA and β-LG, casoplatelins, from GMP, seroporin and albutensin A,
derived from BSA, and lactoferrin and lactoferroxins from lactoferrin
(Jelen, 2003).
3.2.1 Coage cheese (Whey cheese)
Whey cheese making is an ancient technique that is generally used
around the world following traditional and small-scale production. It is
one of the most direct forms of recovery of serum proteins, which,
accompanied by certain residual fat, are denatured and coagulated after
the application of heat treatment. As a general rule, if the sky is heated to
more than 70°C to pH below 3.9, serum proteins precipitate and, for this
67
precipitation to be complete, whey must be heated to at least 90°C and kept
at this temperature for several minutes (Jelen, 1992).
Whey cheeses are given dierent names depending on the country
and region where they are produced: in Spain it is called coage cheese; in
Norway, Mysost Primost, Gjestost or Grubransdalsost; in Portugal,
Requeijão; in Italy, Ricoa; in France, Serac, Brousse, Broccio, Greuil; in
Greece, Manouri, Myzithra, Anthotyros; in Swierland, Schoenziegr,
Hudelziger, Mascarpone; in Israel, Urda; Ricoa being the most important
and best-known cheese whey in the world, along with Mysost (Jelen, 2003).
Whey cheeses are signicantly dierent from each other, in terms of
their chemical composition, mainly due to variations in the origin and type
of whey, as well as the way they are made. These cheeses are made with
whey of sheep, goat and bovine origin. In Mediterranean countries they
are normally based on sheep serum due to the economic importance of
these ruminants in this area and their higher protein content than goat and
bovine serums, which have a lower cheese yield. This type of cheese is
characterized by good digestibility, being rich in protein and a high
nutritional value, because it contains all the essential amino acids
(especially methionine and cysteine) in sucient quantities to meet human
needs (Jelen, 2003).
Coage cheese is mainly made from sweet whey without cream. In
some cases, a small percentage of skim milk is added to the whey.
Generally, it is made by heating the whey to high temperatures and adding
acid, to bind the curd particles together. Whey contains the proteins
lactalbumin and lactoglobulin, coagulable in heat, and in the case of
skimmed milk, also casein. Precipitation takes place in such a way that the
curd particles oat on the surface of the whey; This is achieved by stirring
and heating the serum precisely. It is a product with a soft and fragile
texture (Zehren, 1976).
Technological process for the production of coage cheese: (Zehren,
1976)
68
a. Serum preparation
The whey used to make coage cheese must be sweet (not too acidic).
The ideal is to use whey from the production of double cream, pear or other
low-acid cheese. The acidity of the whey should be determined using the
titration test. The optimal acidity of whey is 37-40°D. High acid does not
result in good coage cheese and must be neutralized with baking soda to
decrease the level of acidity. The manufacture of coage cheese is very
simple to make from cheese whey from preparations that produce sweet
or moderately acidic whey.
b. Heating and resting of the serum
The remaining serum is heated to approximately 85° C. This is gently
shaken as the temperature rises. When the temperature reaches 85° C,
about half a liter of acid whey or white vinegar is added in 5 - 6 times its
volume in water per 100 liters of whey. It can also be prepared without
aggregations. Acid whey should be added quickly, while vigorously
shaking the contents of the tub, to prevent localized coagulation. As soon
as the acidic whey has been added, the stirring stops and while the whey
swirls in the vat, the curds should oat on top forming a compact mass.
The heating rate, the stirring method, and the acidity of the whey all
inuence the amount of whey to be added. Then the heating is suspended,
it is left to rest until a fairly compact dough is observed.
c. Drained and drained
The albuminous clot slowly rises to the surface where it forms a thick
layer that is removed by means of a skimmer or ne-mesh cloth. The whey
can also be removed by siphon, opening the draining tap, being careful not
to move the curd, as its particles are so ne that they are lost in the whey
with movement. The curds are then placed in ne bags or canvases, which
are hung or placed on a draining table and left to drain overnight (12-18
hours). It is advisable that coage cheese drain overnight in a refrigerated
room.
d. Kneading and salting
69
The coage cheese is removed from the canvases or bags and
kneaded perfectly. If desired, add salt to a proportion of 1 to 1.5%, knead
well while mixing, to obtain a uniform dough that can be preserved for a
few days.
e. Handling coage cheese
After the coage cheese is kneaded, it is packed using parchment
paper or in plastic bags and sealed immediately to prevent contamination.
f. Conservation
Packed coage cheese should be placed in special boxes, stored in a
refrigerator at a temperature of 4 - 5° C and marketed quickly. If there is
no refrigerator, it should be kept in a cool and clean place. It is a product
of high humidity, approximately 80% and very perishable, so it must be
consumed quickly.
3.2.2 Fermented milks
The benecial eects of consuming milk can be increased when
fermented milks are consumed, especially with probiotic characteristics,
that is, they have viable, non-pathogenic bacteria that exert a benecial
function in the individual. There are currently several studies, both in
animals and in humans, that support the performance of the intestinal
microbiota in the regulation of gastrointestinal sensory and motor
function, the prevention of colorectal carcinogenesis, immunological and
metabolic aspects, and behavior (Abreu, 2012), but it should be noted that
the person who performs a specic action at the health level is always a
specic strain and not all probiotics in general.
To produce benecial eects on the host, probiotics do not
necessarily have to colonize the target organ, although they do arrive alive
in sucient quantity to aect its microecology and metabolism. Thus, most
probiotic strains are able to reach the colon alive (in a variable percentage)
passing through the entire upper gastrointestinal tract, and their viability
will depend on many factors: on the one hand, the intrinsic factors of the
probiotic, and on the other, dependent on the host, such as, for example,
70
the degree of acidity in the stomach, the length of exposure to the acid, the
concentration and duration of exposure to bile salts and others (Olveira
and González, 2016).
Fermented milks have proven to be nutritionally beer than other
dairy products such as cheese, cream, buer, etc., due to their nutritional
value similar to that of milk, but with greater digestibility than milk thanks
to its low pH and lower lactose concentration. In addition, in recent years
there has been an increase in interest in foods with a positive eect on
health beyond their nutritional value. Among them, in the eld of
fermented milks, probiotics stand out, partly due to the fact that this matrix
is capable of keeping bacteria viable and that its consumption is
recommended daily (Erdmann et al., 2008).
Fermented milks in general, and probiotics in particular, have been
aributed a large number of properties, being recommended for lactose
intolerance, diarrhea, constipation, presence of Helicobacter pylori,
prevention or improvement of infections, improvement of the immune
system, atopic eczema, etc. (Baró-Rodríguez et al., 2010; Khani et al., 2012;
Sánchez et al., 2009). The genus Lactobacillus has a long history of use and
safety in the manufacture of dairy products and it is for this reason that the
possibly probiotic strain Lactobacillus plantarum C4 was chosen, isolated
by our research group and which demonstrated antimicrobial and
microbiota-modulating activity, as well as immunomodulatory properties
(Bergillos-Meca, 2014; Bujalance et al., 2007; Fuentes et al., 2008;
Puertollano et al., 2008).
During fermentation, and mainly depending on the strain used,
dierent bioactive peptides can be released (Gobbei et al., 2002).
Biologically active peptides are peptides derived from food that exert on
the body, beyond their nutritional value, a physiological eect similar to
that of hormones, with fermented milks being an excellent source of them
(Donkor et al., 2007; Erdmann et al., 2008). Some of these peptides have
been shown to have antihypertensive, antioxidant, antibacterial,
anticancer, immunomodulatory, and opioid activities, as well as mineral-
71
binding and regulatory capacity in metabolic syndrome (Donkor et al.,
2007; Korhonen, 2009; Minervini et al., 2003; Muguerza et al., 2006; Ricci et
al., 2012).
These peptides are inactive in the protein sequence, being released
during gastrointestinal digestion or during food processing, such as
fermentation, heating, etc. (Hernández et al., 2016). Bioactive peptides
normally contain between 2 and 20 amino acids and their amino acid
activity is based on their composition and amino acid sequence, on which
their physicochemical properties such as charge or hydrophobicity depend
(Erdmann et al., 2008). The most studied peptide activity is the inhibition
of angiogensin-I converting enzyme (ACEi), which plays a crucial role in
the regulation of blood pressure.
Although most of the publications on peptides with ACEi or
antihypertensive activity have been made with peptides from cow's milk,
in recent years goat's milk proteins are gaining importance as an alternative
source of peptides with this activity (Espejo et al., 2013; Haque et al., 2007;
Park et al., 2007; Ricci et al., 2012). On the other hand, some researchers
have pointed out that antioxidant peptides present in food play a vital role
in maintaining the body's antioxidant defenses, as well as in protecting the
food from oxidation. Finally, peptides with antibacterial activity have also
been discovered, useful especially for subsequent application in industry
(Benkerroum, 2010).
It is considered that there are 10 bacteria in the human body for every
human cell and that the intestinal microbiota fullls three major functions:
nutritive and metabolic, protective and trophic (Prados et al., 2015). Among
the pathologies in which the benets of probiotics have been demonstrated
are the treatment of diarrhea, combating Helicobacter pylori, necrotizing
enterocolitis, eliminating or reducing the eects of allergy, chronic
inammatory bowel disease and improving lipid metabolism of
cholesterol and triglycerides (Vilaplana, 2015).
Probiotics help in the regulation of the immune response and their
continuous use is advantageous for the health of the consumer,
72
participating in the modulation of the normal intestinal microbiota,
reducing the risk of intestinal disorders, preventing diseases such as
infections and food allergies, reducing cholesterol levels, stabilizing the
intestinal mucosa and relieving the symptoms of lactose intolerance (Kich
et al., 2016).
The best-known fermented milk is yogurt, a functional food
obtained by fermentation of lactic acid bacteria in milk. Since ancient times,
its eects on human health have been widely known, including the
prevention of colon cancer, lowering cholesterol, improving intestinal
microbiota, eects on the immune system, among others. The bacteria
responsible for these eects are the acid-lactic-probiotic bacteria that
ferment milk (Parra, 2012). Currently, there are dierent commercial
preparations of probiotics, generally mixtures of lactobacilli and
bidobacteria (Santillán et al., 2014).
The emergence of antibiotic-resistant bacteria as well as natural ways
of suppressing the growth of pathogenic microorganisms have contributed
to the concept of probiotic microorganisms, which not only compete with
and suppress undesirable fermentation in the human gut, and equally
important produce a large number of benecial eects on consumer health
(Nagpal et al., 2012; Kailasapathy, 2013), as they act on the intestinal
ecosystem, stimulating both mucosal and non-immune immune
mechanisms, through antagonism and competition with potential
pathogens (Villanueva, 2015).
But it is not enough for food to have enough presence of probiotic
microorganisms. Consumer acceptance is a key aspect in the development
of functional foods, which in general are not perceived as a separate
category from natural foods, which is favorable; However, acceptance is
not unconditional and the appearance and quality of the product, as well
as the clarity of its statement, are important aspects in its acceptance. It has
been pointed out that educational level, geographical origin and gender
are variables in relation to perception and that the aitude of doctors and
dieticians is important for this acceptance (Illanes, 2015).
73
These potential eects of fermented goat's milk could be related to
the inuence on adipocyte lipid metabolism and, specically, to an
increase in diet-induced thermogenesis, which would lead to higher
energy expenditure and less fat storage. Another possible mechanism
associated with the consumption of fermented goat's milk and the
improvement of body composition could be related to the current evidence
supporting the consumption of milk protein and the role of dairy in satiety,
favoring weight loss and the prevention of weight gain. In this sense,
fermented goat's milk induces the elevation of plasma leptin levels and the
reduction of ghrelin levels, decreasing appetite, increasing the feeling of
satiety and, consequently, reducing body weight (Bendtsen, 2013).
Fermentation is a simple, inexpensive, and safe way to preserve
milk. In areas where modern milking and milk collection equipment is
available, and where there is generally a great deal of knowledge and
experience in raw milk preservation techniques, and where they also have
good transport and distribution systems, there is no need to use
fermentation as a preservation method. Conversely, in areas or countries
that do not have all of these mediums, milk fermentation as a means of
preservation still retains the importance it originally had. Lactic acid
bacteria change the characteristics of milk, so that most undesirable
microorganisms, including pathogens, cannot grow in it, or even die.
Among the changes that occur in milk is the decrease in pH (up to
4.6-4), a factor that contributes to the maintenance of a low pH in the
stomach after consuming milk; inhibition of microbial development by
undissociated acids (e.g., lactic acid), and by other metabolites such as
H2O2 and other substances with antibiotic activity; low oxide-reduction
potential; and the consumption by lactic acid bacteria of components that
are vital for other microorganisms.
Proper pasteurization of raw milk destroys any pathogens that
might survive fermentation. There are many dierent fermented milks, but
when it comes to the technology of their manufacture, they are all similar.
Fermented milks can be classied in several ways, but their classication
74
is generally accepted according to the type of microorganism used in their
production (Pérez and Sánchez, 2012).
75
Chapter IV
Technology for the production of fermented milks
The technology of fermented milks is simple and small-scale
brewing requires only remarkably simple equipment. Large-scale
manufacturing requires consistent, low-cost production, which requires
greater control and more sophisticated equipment, although the basic
manufacturing principles are the same. There are many types of
fermented milk that are made using similar technology and, in many
cases, the dierences are limited to the type of starter culture and the total
solids content of the milk (Pérez and Sánchez, 2012).
Traditionally, yogurt is made using the starter cultures
Lactobacillus delbrueckii. subsp. bulgaricus and Streptococcus
thermophilus. These bacteria provide man with some health benets, but
they are not natural inhabitants of the intestinal tract and do not survive
under high concentrations of acid and bile salts. The solution has been to
incorporate probiotic bacteria into fermented dairy products because
these are live microbial cultures, used as dietary supplements or food
ingredients which, when ingested, produce a benecial health eect to the
host, improving the balance of the ora of the gastrointestinal tract,
inhibiting or preventing the growth of pathogenic bacteria that cause
diseases (Hernández et al., 2016).
The general principle of processing methods in goat's milk are the
same as those used in cow's milk, which consist of reducing the pH and
activity of water to prolong its shelf life. The acid gel of goat's milk is
characterized by rmness and lower viscosity compared to cow's and
sheep's milk.
The viscosity of the gel is associated with the casein content in milk,
especially with the α-s fraction casein, which is in goat's milk from 25 to
30%. In addition, the appropriate heat treatment, the addition of
76
stabilizers and the type of mother culture applied, are the other factors
that reduce the syneresis intensity (Hernández et al., 2016).
4.1 Types of fermented milks
4.1.1 Fermented milks with thermophilic lactic acid bacteria
They are the most commercialized products. The microorganisms
responsible are strains of Lactobacillus delbrueckii subesp. bulgaricus,
thermophilic bacteria whose optimal growth temperature is between 42 -
43ºC. During lactic fermentation carried out by these bacteria, metabolites
such as acetaldehyde and diacetyl are produced that give them a
characteristic taste and aroma. Lactic acid is also produced until pH
values of 3.8 – 4 are reached. This increase in acidity causes the casein in
milk to coagulate, improving its preservation (Sampablo, 2019).
a. Acidophilic milk: Originally from the USA. It is milk fermented by
Lactobacillus acidophilus with a curdled, mixed or liquid texture and
a mild avor.
b. Yoghurt or yoghourt: A coagulated milk product obtained by lactic
fermentation by the action of Lactobacillus delbrueckii subsp.
bulgaricus and Streptococcus thermophilus from milk or concentrated
milk, whether or not skimmed, or from cream, or from a mixture of
two or more of these products, with or without the addition of other
milk ingredients, which have previously undergone heat treatment
or other treatment, equivalent, at least, to pasteurization. All the
microorganisms producing lactic fermentation must be viable and
present in the milk part of the nished product in a minimum
quantity of 107 colony-forming units (CFU) per gram or millilitre.
Depending on the products to be added, or the application of heat
treatment after fermentation, dierent types of yogurts appear: sweetened
yogurt, sweetened yogurt, avored yogurt, yogurt with fruit, juice and/or
other foods, pasteurized yogurt after fermentation. Pasteurized yoghurt
after fermentation meets all the requirements established in the denition
of yoghurt except for the viability of the microorganisms producing
77
fermentation, as it has been subjected to a subsequent thermal process by
which the lactic acid bacteria it contained have lost their viability
(Sampablo, 2019).
4.1.2 Fermented milks with mesophilic lactic acid bacteria
a. Filmjölk: It originates in Sweden but is consumed in northern
Europe in general. The bacteria involved in fermentation are
mesophilic, i.e. their optimal growth temperature is between 20-
22ºC. Among them Lactococcus lactis, Lactococcus lactis cremoris,
Lactococcus lactis diacetylactis and Leuconostoc mesenteroides
cremoris.
4.1.3 Fermented milks with lactic acid bacteria and yeasts
They are produced by the heterolactic fermentation of milk by the
action of bacteria (lactic fermentation) and yeasts (alcoholic fermentation).
They are slightly alcoholic beverages (up to 2% ethanol), sparkling, due to
the CO2 produced and acidic as a result of the lactic acid generated.
a. Ker: Its alcohol content is low (in order of 0.5%). Bacteria of the genera
Lactobacillus, Leuconostoc and Lactococcus and yeasts are involved in the
fermentation of milk; both lactose fermenters (Kluyveromyces marxianus)
and yeasts that ferment without the need for lactose (Saccharomyces sp.)
(Sampablo, 2019).
b. Kumys: It is native to Mongolia. Traditionally it was made with mare's
milk, but today it is made with cow's milk. It contains more alcohol (up to
3%) than ker, due to sucrose's addiction to milk. Bacteria such as
Lactobacillus acidophilus and Lactobacillus delbrueckii subsp. bulgaricus and
yeasts such as Kluveromyces marxianus are involved in fermentation
(Sampablo, 2019).
4.1.4 Fermented milks with lactic acid bacteria and moulds
a. Villi: is a viscous fermented milk, native to Finland. The starter culture
is made up of lactic acid bacteria and molds such as Geotrichum
candidum. The milk used as raw material is not homogenized after
78
pasteurization, so the cream is separated on the surface and is where
mold develops. During fermentation, this mold produces a large
amount of C02 (Sampablo, 2019).
b. Condensed milk
Condensed milk Condensed milk is a by-product derived from whole
milk, which is obtained by partially evaporating the water in the milk with
the addition of sugar, helping to preserve it. Due to its high energy content
(Table 1), condensed milk has been used in the food industry as a
sweetener for fruits, condensed milk, due to its high sucrose content,
inactivates the microorganisms present in the product, which is not highly
recommended as a basic food for healthy diets. In the nutritional eld, it
is not highly recommended to consume it in high quantities, due to the
high sugar content it contains, in this case children could have dental
problems and in the future it could cause chronic diseases such as obesity,
diabetes (Gavino, 2021).

4.2 Condensed milks
a. Crystallization Lactose in milk is present in two isomeric forms
which are called α and βlactose, the α form tends to crystallize due
to its low solubility which tends to crystallize in products such as
condensed milk this is due to the solubility of lactose decreases due
to the high sugar content that is added in condensed milks, which
can lead to the crystallization of condensed milks (Verhelst, 2015).
b. Thickening The main physical defect of condensed milk is the
thickening or change in viscosity, this is due to transitions in the
composition of the milk or its heat treatment by the addition of
sugar or stabilizing salts (Verhelst, 2015).
c. Color change The color change due to the eect of its heat treatment
at the time of pasteurization, the presence of the golden color
increases because the pH increases above 7.0, which can be solved
with a proper heat treatment in the proper evaporation of the milk.
The appearance of color is due to the evaporation time and the
volume of the mixture and the heat treatment that is carried out
manually or with appropriate equipment (Verhelst, 2015).
4.2.1 Technological process for the production of condensed milk
According to (López, 2022), the following procedure must be carried
out for the production of condensed milk:
- Reception
Reception is carried out in storage tanks.
- Filtration
In this part of the process, a cloth or membrane is used to lter the milk
and all impurities present at the time of milking the goat are removed.
- Pasteurization
Goat's milk is heated to a temperature of approximately 65°C, in this
process all the microorganisms present in the milk are inactivated.
81
- Addition
Sugar is added by making a separate dilution for beer
homogenization, mixing it homogeneously to avoid generating lumps in
the pot at a temperature of 70°C for about 60 min.
- Concentration
The temperature is lowered to approximately 50°C until it acquires the
required texture, this stage is the important one to consider the
temperature and homogenization because if it is at a high temperature it
tends to burn.
- Cooling
The temperature of the condensed goat's milk is lowered to 15°C for 40
to 60 min.
- Packaging
The nished product is packaged in heat-resistant glass jars which were
sterilized before nishing the process of making condensed goat's milk to
avoid contamination when in contact with it.
4.2.2 Buer
Buer can be dened as cream or simply as high-fat milk. The process
of obtaining the cream is carried out by simple means such as keeping the
whole milk at rest for a certain period of time in order to ensure that the
fat rises due to the eects of gravity. The fat of the milk has a lower density
than the rest of the components of the milk and for this characteristic it
rises to the surface of the milk forming what is called (the cream). Under
these conditions, this element can be removed by means of ladles and the
resulting product is called cream. Another way to obtain cream, already
at an industrial level, is by using centrifugal force.
In fact, equipment is manufactured equipped with rotating plates with
special characteristics that are intended to separate the heavier elements
of milk from the lighter ones. In this way, the fat is separated from the rest
82
of the components of the milk. The resulting product, as in the previous
case, is called cream. There are two types of cream depending on the
degree of acidity it has and consequently, the type of buer you want to
obtain.
Thus, we speak of sweet cream and sour cream. Sweet cream is one
whose acidity remains at levels similar to those of normal milk. On the
other hand, sour cream is one that, as a result of the fermentation of lactose
by the action of microorganisms, has increased levels of acidity. And, at
the same time, the taste and pleasant smell of it has been enhanced, a
phenomenon that is transmied to buer (Guzmán, 2000).
Buer obtained from sour creams, although it is true that it is beer
accepted by the consumer, has a shorter shelf life. The reason for this
phenomenon is that the product can reach what is called over-ripening
due to the action of microorganisms incorporated during the inoculation
and maturation process, For this reason, companies choose to produce
buers from pasteurized cream to which lactic ferments have not been
incorporated and it is thus that in the market it is dicult to nd the
product obtained from acid creams (Guzmán, 2000).
4.2.3 Stages of production of goat's milk buer
It corresponds to the reception and quality control of the raw material.
The main controls to be carried out at this stage are the determination of
the acidity of the cream and especially the temperature control. The process
of making buer requires the use of temperatures that do not exceed 80C.
- The cream cooled to 8°C undergoes the whipping process. The
specications for this stage are detailed above.
- Once the beating stage is nished, the grain is washed. At least three
washes are carried out. The last wash is done with salt water. The
amount of salt corresponds to 3% of 10 kilos of buer calculated.
- Kneading, the stage after washing, has among its objectives to
distribute salt, regulate humidity and improve the texture of the
83
product. The buer is kneaded until the humidity is not higher than
16%.
- Once the kneading is nished, the buer is molded, packaged and
stored. The storage temperature should be no higher than 50C.
- Unconventional derivatives of goat's milk are lesser-known but
equally valuable dairy products, such as fermented milks, whey,
coage cheese, condensed milk, and buer.
These products have a unique taste and texture that make them
popular with consumers looking for dierent and authentic dairy
products.
- Unconventional goat's milk derivatives are also an excellent source
of nutrients, such as protein, calcium, and vitamins, making them a
healthy alternative to conventional dairy products.
- The production of these products requires a high level of skill and
knowledge to ensure the quality and safety of the nal product,
especially in the case of fermented milks and buer.
- Despite their lower awareness and marketing, unconventional
derivatives of goat's milk are gaining popularity due to their
distinctive taste and nutritional benets, which has led to an
increase in the production and marketing of these products
worldwide.
In theory, unconventional goat's milk derivatives are valuable and
unique dairy products that oer a healthy and authentic alternative to
conventional dairy products. Its production requires skill and knowledge
to ensure the quality and safety of the nal product, but its popularity is
on the rise due to its distinctive avor and nutritional benets.
