Objective: Development of Sugarcane Vinegar.
Principle: Sugarcane is one of the main crops worldwide, and it has an important impact on environmental issues. Sugarcane is used in daily routine life in many ways like as vinegar, jiggery, juices etc. In India sugarcane crop is best cultivated in the west U.P. Sugarcane original vinegar drink with high nutritional quality was produced from fresh sugarcane juice using the yeast culture and acetic acid bacteria by fermentation techniques such as submerged alcoholic fermentation followed by acetic fermentation at room temperature. Refined sugarcane is the primary product of sugarcane juice, during its processing; various other valuable products are also obtained in an unrefined form such as brown sugar, molasses, jaggery and vinegar. Sugarcane juice is widely used in the treatment of jaundice, hemorrhage, dysuria, and other urinary disease. Nowadays sugarcane vinegar is also used in Indian kitchens commonly in pickles, salads, etc. Vinegar is extremely useful for human health including antimicrobial activity, blood pressure reduction, antioxidant activity, reduction in the effects of diabetes, and prevention of cardiovascular disease. Vinegar can be made from any carbohydrate source, amylaceous, or sugary substrate through two successive fermentations: alcoholic fermentation, which is carried out by means of yeasts, and acetic fermentation, with acetic bacteria as the protagonist.

Objective: Preparation of Turmeric powder
Turmeric (Curcuma longa L), the ancient and sacred spice of India known as ‘Indian saffron’ is an important commercial spice crop grown in India. It is used in diversified forms as a condiment, flavouring and colouring agent and as a principal ingredient in Indian culinary as curry powder. It has anti-cancer and anti-viral activities and hence finds use in the drug industry and cosmetic industry. 'Kum-kum', popular with every house wife, is also a by-product of turmeric. It finds a place in offerings on religious and ceremonial occasions. A type of starch is also being extracted from a particular type of turmeric. The increasing demand for natural products as food additives makes turmeric as ideal produce as a food colourant. India is the largest producer, consumer and exporter of turmeric in the world.

Objective: Development of Potato chips
Potato is a perishable commodity and cannot be preserved longer in fresh form. Although for some time potatoes can be preserved by low temperature storage but this low temperature storage results in many undesirable biochemical changes in the quality of the potatoes. Another alternative for the preservation of potatoes is to conversion in the shelf stable value-added processed products. Further, value-addition and processing of potato will also ensure the availability of wholesome, safe, nutritious, and acceptable food to consumers throughout the year along with simultaneous reduction in post-harvest losses and profit to the farmers for their produce. Potatoes are processed into a great variety of products, including cooked potatoes, par-fried potato strips, French fries, potato chips, potato starch, potato granules, potato flakes and dehydrated diced potatoes and others. Globally, only two potato-based snack foods i.e., chips/ wafers and French-fried potato are the main value-added products of potato, accounting for more than 42% of the potato based processed products. Such type of fried products is loved for convenience and their premium taste, flavour, and texture. With the technological advancements, now potato processing is highly industrialized and market driven. Like other processed products, the finished product quality of potato based value-added products severely depends upon the quality of raw potatoes used. Therefore, the major challenge in potato processing is to fulfil the tuber quality requirements specifically, tuber morphology, reducing sugar (=0.1%) and dry matter content (=20%). Alternatively, we can infer that all type of potato is not suitable for processing. The crispy texture of potato chips is one of the most important quality indicators of the finished product, apart from colour, odour and flavour. Potato chips texture is often described in terms of crispness, hardness and crunchiness. This crispy/crunchy character is an important sensory characteristic on which consumers base their appreciation.

Objective: Development of Salted Banana chips.
Banana is the second most significant natural product harvest of India close to mango. It is accessible round the year and due as it would prefer, nutritive and the rape tic worth. It is most loved product of all classes of individuals. It is a rich wellspring of sugar and nutrients especially nutrient B. Banana assists with diminishing the danger of heart illnesses. Banana is a famous organic product because of its low cost and high nutritive worth. Banana contains about 20% sugar and sensible measure of Vitamins A, B and C. This is considered to be a rich source producing food. It is consumed in several forms and among many worth added arrangements, Banana Chips is viewed as the main thing. Seared banana chips are typically delivered from under-ready banana cuts southern style in sunflower oil or coconut oil. These chips are dry (like potato chips), contain about 4% water (table), and can be salted, spiced, glossed over or jaggery covered. Some of the time banana enhancing is added.

Objective: Production of Chocolate.
The major ingredient of chocolate is cocoa mass, which is mixed with sugar, and in case of milk chocolate, also with milk powder. The conching process then follows, which is important for the development of full chocolate flavour. Melted cocoa butter is added, the chocolate mass becomes liquid and is cooled, tempered and poured into moulds to form chocolate products.
Mixing of ingredients
Sugar, cocoa mass and milk powder are intensively mixed forming a dry powder. This powder is pre-ground in various types of mills and then finely ground in a 5-roll refiner. The size of particles in chocolate is between 15- 70 mm (average 25 mm). Small operators use vertical ball mills. Optimum flow properties are required for further processing. The yield value required differs according to the potential use (e.g. hollow moulding or enrobing). The particle size affects both the yield value and the plastic viscosity. In order to reduce recipe costs, the most expensive major constituent (i.e. fat) should be used in the smallest possible proportion which will give correct flow characteristics.

1.1 Carbohydrates Biochemistry
Carbohydrates are essential for life, both in plants and in animals. They are organic chemical compounds made of C, H, and O. These elements get arranged in different ways so that several simple, and stored complex compounds (starch in plants and glycogen in animals) are available in abundance on the Earth. They are involved in enormous biological and nonbiological functions. Their biological functions, found in all living things, are the chief energy source for men and animals, even for herbivorous fishlike carp and rohu fingerlings. Carbohydrates are also essential structural components like nucleic acids, containing genetic information. One must recognize the protective function in cells, plants, and human health management. Even bacteria form a glycocalyx and biofilm for protection. Knowledge about their involvement in blood groups helped to identify universal donors, universal recipients, and genuine donors for the recipient to save a life. Carbohydrates are found as a storage structure for energy in emergency conditions.
Upon combustion, they yield carbon dioxide and water. Autotrophs (plants) synthesize them from carbon dioxide and water to grow, reproduce, and store, but heterotrophs (humans and other animals) use them, too. In plants, they occur as fibers, supporting structures, and simple sugars. The plant carbohydrates are used for preparing adhesives, fermentation, foods, and papers. Cotton fibers are used to make clothes to cover the body and protect humans and animals against adverse climatic conditions.

Carbohydrates are the most abundant class of organic compounds found in living organisms. Carbohydrates are also called sugars and are found in plants and animals. Plants synthesize them through photosynthesis (endothermic) by fixing carbon, hydrogen, and oxygen in the presence of solar energy and chlorophyll pigments.
nCO2 + nH2O + energy → CnH2nOn + nO2
Carbohydrates are stored as starch in plants as a source of energy. They are also stored in animals as glycogen in muscles and the liver. They are also found in skeletal structures of cell walls in plants (cellulose), bacteria (peptidoglycans), insects, and crustaceans. This stored food is consumed by animals and man, and upon their oxidation in the body, energy is released for various metabolic activities (work, growth, and various productive functions). Compositionwise, plants are more prosperous in carbohydrates (30%) than animals (1%), with water at 60% and ash at 4%. Plants are poor in proteins (5%) and lipids (1%) as compared to proteins (20%) and lipids (15%) in animals.
2.1 Introduction to Carbohydrates
Carbohydrates or saccharides (sakcharon=sugar or sweetness) are a chemical term applied to a large group of substances, which are organic compounds containing elements Carbon, Hydrogen, and Oxygen in a ratio of 1:2:1. Hydrogen and Oxygen atoms are in the ratio of two to one as in water molecules. As the ratio of hydrogen to oxygen is like H2O, they are also known as “hydrates of carbon” and are represented as (CH2O)n. But there is an exception to this general formula. Deoxyribose (C5H1OO4) and rhamnose (C6H12O5) do not have the required ratio of 2:1 for hydrogen to oxygen. On the other side, some compounds possess this required ratio but are not carbohydrates, e.g., formaldehyde (CH2O), acetic acid (C2H4O2), and lactic acid (C3H6O3). Further, some carbohydrates have nitrogen(glucosamine), phosphorus, and sulfur but do not satisfy the above general formula. The simplest sugars are called monosugars or monosaccharides. There are two main functional groups in

Hydrates carbons (saccharides) found in nature (animals and plants) are classified into three groups based on the number of monosaccharides found or released upon acid hydrolysis. Monosaccharides the groups of carbohydrates.
3.1 Formulation of Monosaccharides
The molecular formula of any monosaccharide (mono=one and saccharide=sugar) is Cn(H2O)n or (CH2O)n. Rhamnose and Deoxyribose are exceptions to the general formula of carbohydrates. Acetic acid (C2H4O2) and formaldehyde (CH2O) are not carbohydrates but have the formula Cn(H2O)n or (CH2O)n. Fitting and Baeyer proposed the formula CHO-(CHOH)4-CH2OH, which indicates the presence of aldehyde and five hydroxyl groups.
More than one monosaccharide molecule unites to form disaccharides, oligosaccharides, and polysaccharides. Monosaccharides, being simpler units, cannot be broken down further. Generally, they have two to ten carbon atoms per molecule (dioses to decoses). The monosaccharides may have either aldehyde or ketone groups. The one possible aldodiose (CH2OH.CHO) is glycolaldehyde (2-hydroxyethanal), but ketodiose is not possible since there are only two carbons. The glucose molecular formula C6H12O6 represents the number of C, H, and O atoms but not groups. However, the proposed formula, CHO-(CHOH)4-CH2OH, indicates the presence of an aldehyde and five hydroxyl groups. These simple sugars or monosaccharides have carbon backbones linked by single bonds with hydrogen and hydroxyl groups attached in an unbranched manner.

Oligosaccharides comprise 2 to 10 units of monosaccharide molecules, which are released upon hydrolysis. The oligosaccharides are classified depending upon the number of monosaccharide units, e.g., Disaccharides (two monosaccharide units), Trisaccharides (three monosaccharide units), Tetrasaccharides (four monosaccharide units). Disaccharides are the most common oligosaccharides found in nature.
4.1 Disaccharides
Disaccharides are formed when glycosidic linkages covalently bond two monosaccharides together. A glycosidic bond is formed when the hydroxyl group on one of the sugars reacts with the monomeric carbon on the second sugar. A glycosidic bond can be alpha or beta, depending on the steric configuration at carbon one on the monosaccharide unit. During the union of two monosaccharide units, water molecules are eliminated (dehydration reaction or condensation reaction, or dehydration synthesis), and the formation of a glycosidic bond occurs, through which the units are linked via an oxygen bridge.

Polysaccharides comprise several monosaccharide units (more than ten) linked by glycosidic bonds; therefore, they are high molecular weight carbohydrates. They are also called polyanhydrides of simple sugars. The most common monosaccharide unit of polysaccharides is D-glucose. The polysaccharides may differ in their monosaccharide units, molecular weight, chain nature, glycosidic bond types (alpha, beta), and linkages (1-2, 1-3, 1-4, or 1-6). They are tasteless, colorless, amorphous powders that are a little water-soluble. Some may form colloidal solutions. The polysaccharides provide structural stability (structural polysaccharides) to cells, prevent cells and tissues from drying out due to their water-binding properties, and reserve food for the future. Reserved polymeric carbohydrates are osmotically less active and can be stored in large quantities within the cell.
The right and left end of polysaccharides, respectively, are called the reducing and non-reducing ends. Based on the functional aspects, they are grouped in two ways.
• The first way depends on its digestibility—1. Nutrient polysaccharides are (digestible) starch, dextrin, and glycogen, and 2. Structural polysaccharides are (indigestible), chitin and cellulose.
• The second way, depending upon the constituent monosaccharide units, they are 1. Homoglycans (same units), and 2. Heteroglycans (different units).

6.1 Metabolism
Dietary components like carbohydrates, lipids, and proteins are continuously broken down and synthesized through various chemical reactions (exergonic or endergonic) that are concerned with energy. These processes not only break them down but also interconvert them for their synthesis. Dietary components, when utilized, are known as nutrients the body. The number of reactions occurring in living cells maintains the body cells and fluid’s homeostasis and dynamic status. To keep the dynamic state of a cell, many reactions are going on to synthesize or break down the different types and sizes of molecules. The total of these reactions is known as metabolism.
The metabolism may be anabolic or catabolic. Further, it may be aerobic or anaerobic, depending on oxygen availability. These four terms are explained below:
I. Aerobic and Anaerobic Metabolism
• Aerobic metabolism-- In aerobic metabolism, the carbohydrates (substrate) in the presence of oxygen are metabolized to release energy, carbon dioxide, and water. The released energy is converted to ATP by two processes in the mitochondria (the Krebs cycle and oxidative phosphorylation). In oxidation, the electrons released from a glucose molecule are transferred to reduced NAD+ and FAD. The oxygen (electron acceptor) is reduced to water. Water formation [from H2(g) and O2(g)] is an exothermic reaction. The energy released from the chemical bond of glucose is captured as ATP, and heat is released.

Glycolysis involves a series of reactions to extract energy from glucose to
release two molecules with three carbons called pyruvate. The process is not
dependent on oxygen but can occur under aerobic and anaerobic conditions,
releasing different end products. Under aerobic conditions, the pyruvate formed
is then oxidized in the mitochondria to CO2 and H2O. The energy released in
glycolysis is in the form of ATP (High Energy Bond). All the reaction steps
occur in the cytoplasm, as it is the extramitochondrial pathway. In anaerobic
conditions and the absence of mitochondria (RBC), the end product of
glycolysis is lactic acid.
The net reaction of Glycolysis (anaerobic) may be summarized as under
Glucose + 2ADP + 2Pi → 2 Lactate + 2ATP
7.1 Steps in EMP Cycle or Glycolytic Pathway
Table 7.1: Steps and enzymes of glycolysis or EMP cycle.

The Hans Krebs cycle, known by different names like the citric acid or tricarboxylic acid cycle, was named after the scientist Hans Krebs. The citric acid cycle is named after the citrate product formed in the cycle. The name tricarboxylic acid is given as citrate itself, which is a tricarboxylic acid due to the presence of three carboxyl functional groups (-COOH).
The tricarboxylic acid (TCA) cycle occurs in aerobic conditions and within mitochondrial ETC, involving various sequential oxidoreductase reactions. The cycle requires Acetyl-CoA (C2 molecule) and oxaloacetate molecule (C4 molecule) to begin with the formation of a citrate molecule (C6 molecule). Acetyl-CoA is generated from the pyruvate (glycolysis), the fatty acids (lipolysis), or by oxidative deamination of specific amino acids. The complete oxidation of a glucose molecule results in the end products like energy (ATP), CO2 and H2O. A molecule of Acetyl-CoA has two carbons. It is formed from a three-carbon pyruvic acid molecule generated from the glycolysis of a sixcarbon glucose molecule. Acetyl-CoA is the substrate for this cycle and is an energy-rich molecule having a thioester bond between coenzyme A and acetic acid.
8.1 Formation of acetyl-CoA from Pyruvic Acid
Pyruvate is obtained by glycolysis or the oxidation of glucogenic amino acids. The pyruvic acid produced in the cytoplasm crosses the inner membrane of the mitochondrion to enter the mitochondrial matrix, where it undergoes oxidative decarboxylation, forming Acetyl-CoA. Acetyl-CoA carries (carrier molecule) the acetyl group to the citric acid cycle. It also links various metabolic products with the TCA cycle. Such products can be from the EMP cycle, beta-oxidation, and oxidative deamination of amino acids. Oxidative decarboxylation of pyruvic acid needs a complex enzyme system known as pyruvate dehydrogenase

This alternative pathway for glucose oxidation has enzymes in the cytosol through which glucose is degraded to carbon dioxide. It is also called a shunt because carbon atoms from glucose 6-phosphate take a long route before they proceed down the EMP or glycolytic pathway. This pathway is anabolic in nature as it produces many intermediates. In this pathway, two NADPH are generated from one glucose 6-phosphate molecule. No ATP is generated or consumed.
Overall, this pathway needs three glucose-6-phosphate molecules to complete all the reactions. Therefore, one cycle run produces 2 mol of fructose-6- phosphate, 1 mol of glyceraldehyde-3-phosphate, and 3 mol of carbon dioxide from 3 mol of glucose-6-phosphate with the reduction of 6 mol of NADP+ to NADPH.
Overall reactions of the HMP pathway are as follows:
3 Glucose-6-P + 6 NADP+→ 3 ribulose-5-P + 3 CO2 + 6 NADPH
3 Ribulose-5-P → 2 xylulose-5-P + Ribose-5-P
2 Xylulose-5-P + Ribose-5-P → 2 fructose-6-P + Glyceraldehyde-3-P

The uronic acid pathway is a minor and alternative pathway for glucose oxidation and for the production of uronic acid sugar. Uronic acids of sugars are formed when the terminal carbon’s (C6) hydroxyl group (CH2OH) of sugar gets oxidized to a carboxylic acid. Uronic acid names depend on the name of the parent sugars. Uronic acid of glucose is glucuronic acid, hexose uronic acids are hexuronic acids, and pentose uronic acids are named penturonic acids. The uronic acid pathway is located in the cytosol of the liver and adipose tissue.
The glucuronic acid should not be confused with gluconic acid (aldonic acid) and glucaric acid (aldaric acid or dicarboxylic acid). Gluconic acid (aldonic acid or “onic” acid) is obtained from D-glucose by oxidizing its aldehyde group at C1 to a carboxyl group. Glucaric acid (aldaric or dicarboxylic acid) is formed upon oxidation of both the terminal hydroxyl groups (C1 and C6) and the aldehyde. They have two carboxylic acid groups. This pathway yields pentoses & ascorbic acid or vitamin C (not in primates & guinea pigs) from glucose.

Plants, with the help of photosynthesis, convert simple molecules (like carbon dioxide and water) into more complex molecules (anabolism) through various chemical reactions. Animals synthesize more complex molecules (anabolism) from monomer units through multiple chemical reactions. Anabolism refers to a biosynthesis process involving the sequences of biochemical reactions by which complex molecules are formed in living cells from available monomer units. Anabolic processes include the biosynthesis of complex biomolecules like carbohydrates, proteins, and lipids. The anabolic processes require energy from high-energy bond compounds like ATP.
The anabolic processes related to the biosynthesis of carbohydrates include
(1) Gluconeogenesis and
(2) Glycogenesis
11.1 Gluconeogenesis
Gluconeogenesis is the synthesis of new glucose molecules from noncarbohydrate molecules. The non-carbohydrate molecules that are used for gluconeogenesis are derived from glycolysis, lipolysis, and proteolysis. Examples are pyruvate, lactate, glycerol, and glucogenic amino acids. The liver and kidneys are the preferred organs for the gluconeogenesis process. It also occurs to some extent in the brain. Blood glucose levels are maintained at physiological concentrations through the process of gluconeogenesis in humans and ruminants. The blood glucose drops below normal levels during various conditions like fasting, starvation, pregnancy, lactation, fever, and low carbohydrate diets.

Glycogenesis helps to maintain blood glucose, as it is a primary source of energy for every cell. An inadequate supply of glucose to the body may lead to the failure of the vital organs. Glucose, when in excess, is synthesized into glycogen and stored (glycogenesis), mainly in the liver and muscles (including the uterus). It is also found in other tissues, such as the kidney, brain, heart, and adipose tissues. The stored liver glycogen is broken down (glycogenolysis) into blood glucose when needed. Still, the glycogen stored in muscle is broken down to glucose 1-phosphate and converted to blood glucose later. Either the synthesis or breakdown pathway is primarily active at a time in tissues. Glycogen synthesis and its breakdown are not reversible processes.
The percentage of glycogen stored in skeletal muscles is less ( 1% to 2%) than in the liver (10%). Still, the total quantity of glycogen is greater in muscles due to their greater mass than an animal’s total liver mass. Muscle mass, on average, ranges from 40 to 45 % of body weight for the most mature mammals.
Glycogen synthesis (glycogenesis) is an anabolic process forming a branched homopolysaccharide made of several chains of alpha D-glucose units linked by α-1,4 glycosidic bonds in a linear chain and nearly every ten glucose residues; the chain branches off via α-1,6 glycosidic linkages. The α-glycosidic bonds give rise to a helical polymer structure. The number of glucose units in a single glycogen molecule varies (1,700 to -600,000 units). The glycogen granules are formed on the glycogenin protein in the center, so it acts as a primer, and their number determines the total number of glycogen particles.

Glycogen breakdown is known as glycogenolysis. This breakdown occurs in the cytoplasm of cells of the organs, wherein glycogen is stored. The end product of glycolysis is glucose in the liver, which is glucose-1-phosphate in skeletal muscles.
Glycogen is a polysaccharide synthesized from glucose monomers. Glycogen is stored in the cell instead of glucose because glucose requires more water, whereas glycogen can be stored with much less water. Most of the stored glycogen is in the liver (5% of body weight) and muscle (1 to 2 % of body weight). Muscle and liver glycogen undergo glycolysis for different purposes. Muscle glycogen provides energy for muscular activity, whereas liver glycogen helps to maintain the blood glucose level.
Glycogen contains many glucose residues (up to 120,000) linked by alpha 1-4 glycosidic bonds, forming a straight chain. Glycogen has branches at alpha 1-6 glycosidic bonds at every ten glucose residues. At the reducing end, the carbon one of glucose is free, whereas it is not accessible in the case of non-reducing ends.

Carbohydrates (glucose) are the primary energy source for a body; when digested, glucose is the end product in human beings and simple stomach animals, but it yields volatile fatty acids in ruminants. Precise regulation of levels of blood sugars/glucose in the body is the net result of various processes like digestion, absorption, and metabolism operating under the interaction of various a) enzymes and b) hormones secreted by the different organs of the body. An abnormal secretion of any of the enzymes or hormones associated with the metabolism of carbohydrates disrupts the precise regulation of blood sugar, leading to various disorders.
14.1 Enzyme Deficiency and Disorders in Carbohydrate Metabolism
Usually, various enzymes are involved in the breakdown of carbohydrates, and if their secretion is insufficient, missing, or does not work correctly, it leads to different disorders.
I. Glycogen storage diseases (GSDs, glycogenosis, and dextrinosis)
Glucose is needed by the cells for the generation of energy and other cellular activities. If glucose happens to be in excess, it is stored as glycogen, mainly in the liver and muscles, for future needs. The stored glycogen can be converted back to glucose when the need arises. Many enzymes are related to this interconversion of glucose and glycogen. Deficiencies of one or more enzymes may lead to abnormal glycogen metabolism, leading to glycogen accumulation of normal or abnormal chemical structure in tissue, collectively called glycogen storage diseases (GSDs). Roman numerals identify different types of glycogen storage conditions. They are also classified under various categories like inherited metabolic diseases, autosomal recessive type, and X-linked type (VIII/IX type).

The number of hormones secreted by the body exhibits control over the physiological regulation of glucose sugar level (homeostasis) in the manner needed by the body. Depending upon the situation, hormones may increase or decrease the level of glucose sugar present in the blood or tissues. The glucose is oxidized to yield energy, carbon dioxide, and water.
Glucose, more than the body’s needs, is stored or converted mainly to glycogen and, to some extent, protein and fat. If glucose is less than the need of the body, its denovo synthesis takes place from amino acids or fatty acids, or is formed from the breakdown of stored glycogen. Various hormones are secreted by multiple endocrine glands to control the blood glucose level. If it fails, it leads to hypoglycemia or hyperglycemia conditions. Gluconeogenesis is not developed at birth in the case of a baby pig. Therefore, hypoglycemia in baby pigs is observed within 2 days of age if starved, leading to hypoglycemia, weakness, confusion, and death.
15.1 The Hormones Involved in Homeostatic Regulation of Blood
Glucose Level
The hormones influencing carbohydrate metabolism are explained below:

1.1. Introduction
The terms ‘counselling’ and ‘health promotion’ complement each other when it becomes a matter of an individual’s health. Health promotion is a part of behavioural social science that aims to change the systemic strategies adopted by the individual or group or by the mass community for the betterment of their health which can be achieved by talk therapy known as counselling. In the 21st century, from childhood to adulthood, all people are in a ‘rat race’ for their careers and necessities, which is one of the main reasons for stress generation. Not only that, chemical substances consumed by different food ingredients as food additives, preservatives, etc. but also induce oxidative stress and damage the functional activity of cells, tissues, organs, and systems. This ‘stress’ is a major culprit not only for the deterioration of physical health but also psychological health. Such stress imposition in daily life impairs normal physiological functions, skills, performance, and productivity. Unhealthy food, life, and work styles are also linked to the onset of pathophysiological complications that counselling and health promotion are required to overcome. Besides this, for sportsmen, pregnant women, lactating mothers, and growing children, nutritional counselling and health promotion are indisputable. For disease prevention and early recovery from disease, dietary counselling plays an immense role.
1.2. Counselling
Counselling is an intermittent, interpersonal interviewing process where the counsellor gives advice or suggestions to the client but never gives any direction. Counsellors assist the client in thinking, analysing, and acting to improve their insight power. The counsellor focuses on both the positive and negative sides of a particular event and allows the client to think and rethink its acceptability and unacceptability.

2.1. Introduction
The present century is the century of oxidative stress (OS) that linked to several life-threatening disorders which predominantly affect public health as well as their nutritional status. Unhealthy lifestyle and eating pattern which is major concern for OS. The biological literature first used the phrase “oxidative stress (OS)” in 1970. OS can be defined as a state of imbalance condition between the high level of pro-oxidants and the low level of antioxidant scavenging capacity in the body. The normal oxidative process that occurs in cells is crucial for the existence of life and favours the death of a cell. Free radicals, which are unstable, can form when molecular oxygen breaks up into pairs. This unstable radical has a high level of reactivity and produces reactive molecular species like reactive oxygen species (ROS) and reactive nitrogen species (RNS). To resist the OS and to maintain the redox balance, cells have an inbuilt antioxidant defence capacity, comprising of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPOD) etc. But some pathogenic or environmental conditions may overpower this antioxidant defence system, allowing a portion of reactive oxygen and nitrogen species (RONS) to bypass degradation and create much more reactive radicals. Increased ROS and RNS affect redox balance and damage DNA, proteins, amino acids, and fats, causing alteration of structures as well as action of cells and tissues. This will ultimately produce several pathogenetic elements associated with clinical situations and leads to the development of human aging and numerous diseases. Several dietary components such as whole grains, nuts, fruits, and vegetables are excellent sources of antioxidative vitamins, minerals, nutraceuticals or phytoceuticals that shields the human body from the harmful oxidative injury by scavenging or destruction of free radicals and also by upregulation of endogenous antioxidant defence system. Thereby long-term and sustainable OS remedies can be performed.

3.1. Introduction
Sports nutrition is one of the areas of nutrition that closely coordinates with human anatomy research and the science of sports. The application of nutrition science to a practical daily eating plan intended to optimise the performance of athletes in competitive events, speed up the healing and reconstruction process following intense physical activity, and supply the energy for physical activity is known as sports nutrition. It also seeks to promote wellness and general health. Nutrition is strongly connected to fitness, specifically whilst sports activities are involved. It is necessary to recognize the physiology of the workout on the way to recognizing the specific metabolic pathways that coexist in the course of sports activities practice (O’Donoghue, 2014). Three things are necessary for athletic success: genetic endowments, level of training, and nutrition. It is impossible to change one’s genetic makeup. The most efficient method for enhancing athletic performance is specialized exercise training, and any kind of workout regimen must include adequate nutrition. The dietary requirements of athletes and workout aficionados are different from those of physically inactive people due to variations in their calorie needs as well as macro- and micro- nutrient needs. To achieve peak athletic performance, it is crucial to investigate and evaluate the dietary requirements of athletes prior to, during, and following the contest (Cotugnae et al., 2005). Exercises that improve one’s heart health involve swimming, jogging, and climbing. Other exercises that improve one’s flexibility, power, and endurance of muscles involve stretching and hard training with resistance. For example, if someone decides to choose to lose excess fat and to do so, they would design a regular exercise routine that incorporates all of the above-mentioned elements, as well as choosing more nutritious foods in the diet to meet the higher demands to endeavors. Athletic performance requires sports-related abilities. These neuromotor skills, such as balancing, pace, power, durability, stamina, agility, and execution, are particular to sports.

4.1. Introduction
The food is the main factor known to affect the health of an individual. By interference in the protein synthesis, function and metabolites and alteration in genome expression, the healthy condition must be altered to diseased condition. Side by side we can say that the dietary component directly or indirectly modulates the molecular fingerprint and understanding of which is dealt with nutrigenomics. So, by modulation of a particular gene for a specific disease by nutrition, we can prevent the specific disease and promote the health of a population. Consuming fruits and vegetables on a regular basis has been linked to better health outcomes and diminution of several chronic or life style linked diseases.
Concept of Nutritional Genomics
After completion of human genome sequencing, the unique term “Nutritional genomics” tends to replace the old term “Nutrient-gene interaction”. It has been stated that so many polymorphism can influence protein structure and function. There are several regulatory sites where nutrients can impact the flow of genetic information. The two components of the nutritional genomics field are nutrigenomics, which studies how dietary components interact with the genome to regulate changes in proteins and other metabolism, and nutrigenetics, which determines how dietary components affect genetic variations. (Farhud et al., 2010). Nutrients are as environmental influences can interact with genetic material. It is commonly known that DNA metabolism and repair require a range of dietary elements that serve as cofactors or substrates in metabolic pathways. However, little is known about how cofactors and/or micronutrient excess or deficiency affect the accuracy of DNA replication and repair (Caroline and Fenech, 2008). The response to a particular nutrient, which is determined by the individual genotype, must also be taken into consideration, even though the nutrients can influence the development of a particular phenotypic.

5.1. Introduction
The people of every nation would be healthier if they adopted healthier lifestyles. A Good nutrition, daily exercise and proper sleep are the base of healthy living. A healthy lifestyle denoted by fit, energetic and at minimize possibility for disease. According to WHO, Healthy living is a way of living that helps you enjoy more aspects of your life. It is a way of living that lowers the risk of being seriously ill or dying early. Health is not just about avoiding a disease or illness.
5.2. Concept of Health
According to WHO, Health is the state of complete physical, mental and social well being and not merely absence of disease or infirmity. The holistic approach of health is the individual’s health and lifestyle considering all four factors, physical, intellectual, emotional and social. It concern about the whole body and mind not just a part of the body and the symptoms of the problem. It will look at the lifestyle of the individual such as nutritional deficiencies, reason of stress and why there is a lack of good health and wellbeing. A holistic approach will engage the individual taking responsibility for their health and well-being. They do this by educating themselves and being active in maintaining and improving their health and well-being.
5.2.1. Positive Health
Positive Health is the scientific study of health assets. A “health asset” is a factor that construct stronger health, over and above risk factors for disease. Positive Health works to find which specific health assets produce longer, healthy life, and which health assets lower disease risk and health care costs. The aim is to strive for optimal health —beyond the mere absence of illness.

6.1. Introduction
The best way to combat malnutrition globally among women and children have changed over the last few years keeping pace with the advancement of technology. Information and communication technologies (ICT) have become very important for solving the contemporary nutrition related issues because they provide a vast array of new communication capabilities. In addition to meeting society’s actual needs for ongoing health and nutrition care, ICTs are crucial for facilitating interactive, personalized nutrition communication. People can interact or communicate with others in different countries in real-time through instant messaging, video conferencing or voice over IP (internet protocol). Through social networking platforms like Facebook, Instagram, and others, people from all over the world can regularly converse and stay in touch. In the context of health communication, ICT is referred to as Interactive Health Communication (IHC), which is the exchange of health information and advice and support regarding health-related matters between a consumer, patient, caregiver, or professional using an electronic device or communication technology. Nutrition treatments are less expensive when face-to-face interaction is facilitated by electronic means. These are complementary factors that encourage nutrition communication in an information-age healthcare system, especially when combined with consumers’ growing desire to take charge of their own health. Customers can advantageously use information technology in this system to connect with health professionals and support groups, obtain absolutely relevant information, and take charge of their own health. The “global village,” which has been made possible by modern information and communication technology, allows people to interact with each other virtually as if they were neighbours. Because of this, ICT is frequently examined in relation to the ways that contemporary communication technologies influence society.

7.1. Introduction
Entrepreneurs serve as the catalysts for the introduction of innovative technologies and systems that ultimately lead to societal advancements. These innovations are linked to enhanced lifestyles, progressive thinking, morale, and bravery, along with an improved standard of living. National and global changes are greatly influenced by such kinds of social change. Joseph Schumpeter, an Australian famous economist, is referred to as the father of entrepreneurship. Dhirubhai Ambani was the most enterprising Indian entrepreneur. Jamsetji Tata set a bar for entrepreneurship development in India with the foundation of the Tata group. The father of entrepreneurship in India is Ratan Tata. In public health, nutrition-based entrepreneurship and self-employment are also another emerging topic nowadays. Several entrepreneurs are found in this field mostly due to the challenge of building a business and craving to control their destiny. Not only that, financial independence, personal satisfaction, relief from the frustration of working for someone else, and the opportunity to create the desired lifestyle. Nutrition entrepreneurship offers numerous business-related resources and provides services for social well-being. As for example, the transformation of raw food ingredients into consumable food products, entrepreneurship plays a key role in diversifying and commercializing agricultural products. It adds value of food, prolongs its shelf life, promotes the export of processed items, generates employment opportunities, boosts farmers’ earnings, and makes a significant contribution to the general development of rural areas. Health entrepreneurs like nutritionists, dietitians, physicians, and health counsellors run their practice and make it available for the client to listen to their problems and solve their problems through mental support, motivation, diet therapy, medication, and so on. As a result, the health burdens due to noncommunicable and communicable diseases are reduced.

8.1. Introduction
Micronutrients are vitamins, minerals, and nutraceuticals that do not provide energy and do not raise any sensation of hunger known as “hidden hunger” or “insensible hunger”. Hidden hunger that causes micronutrient deficiency affects 2 billion people globally. Due to the deficiency of micronutrients, different diseases are noted among public health professionals that reflect poor community nutrition. To overcome these deficiency-related diseases, one of the important approaches is food fortification. Food fortification is a public health policy to reduce the number of individuals, who suffer from micronutrient deficiencies within a population. Common examples include iodine-tagged common salt, vitamin A-containing oil, and iron-enriched rice all of which are examples of food fortification. In the agricultural field, food fortification (FF) and/or food enrichment (FE) is the most efficient strategy to overcome various micronutrient deficiencies by the addition of essential micronutrients (vitamins and minerals) to enhance the nutritional value of cultivated crops. According to World Health Organization (WHO) and Food and Agricultural Organization (FAO) of the United Nations (UN), “Food fortification” is defined as “the practice of deliberately increasing the content of an essential micronutrient, i.e., vitamins and minerals (including trace elements) in a food irrespective of whether the nutrients were originally in the food before processing or not, so as to improve the nutritional quality of the food supply and to provide a public health benefit with minimum risk to health” (Pant and Chinwan, 2014). “Fortificant” refers to the incorporation of substances in the food to provide micronutrients. “Micronutrients” refers to the important dietary components, including vitamins and minerals, that are required in very small amounts but are engaged in very critical roles in various body functions and disease prevention.

9.1. Introduction
The three basic need for human survival are- food, clothing and shelter. The requirement of food comes first. Human are omnivorous. They eat mainly natural foods. Before 5000 years ago, cereals were the main food for all civilization and then the complexity of life began to make appearing with the advent of industrialization, flourishing of industry and commerce. Unpolished grains were utilised at first, but in contemporary civilisation, we have begun to prepare them, which results in the loss of essential nutrients. The intake of meats, processed meals, and sugary goods has grown while the general intake of cereals has decreased. People now lack vital nutrients as a result of the departure from natural diets. People began to realise a few years ago that health is a significant concern in addition to flavour, convenience, and quality value. They have thus begun taking nutritional vitamin supplements to make up for the nutrients lost from processed meals. People are increasingly opting for natural nutraceuticals in capsules and tablets, a trend known as medicalization in nutrition, instead of relying on natural food items. Hippocrates emphasized the connection between food and medicine, stating that healthy foods has a strong therapeutic advantages. The ancient Indian medical system known as Ayurveda places a strong focus on the functioning of diet and nutraceuticals in both health and illness.
9.2. What are Nutraceuticals
Stephen De Felice, the founder and chief executive of the Foundation for Innovation in Medicine (FIM), first used the term “nutraceuticals” in 1989 to refer to the broad category of medicines and nutrition. Nutraceuticals are foods or dietary components that not only offer nourishment and energy but also significantly contribute to regulating and preserving the regular physiological processes that keep people healthy. Nutraceuticals included processed meals such as cereal-grains, soups or stews, genetically engineered foodstuffs, herbal items, nutritional supplements, and extracted nutrients. People are increasingly concerned about their healthy wellbeing these days. However, these include a hectic, sedentary lifestyle, unhealthy eating patterns, body image issues, and being afflicted by a number of illnesses. These are the factors driving the global nutraceutical market’s expansion and generating a lot of interest. Numerous health issues of the century, including cancer, type 2 diabetes, heart disease, inflammation, oxidative stress, constipation, and more, can be fought off with the use of these nutraceuticals. Overall, nutraceuticals bring an entirely novel phase in medical science and assist the food companies to promote more creative research strategies. (Dudeja and Gupta, 2017)).

Therapeutic Aspects of Drug-nutrient Interactions
Drug-nutrient interactions are expressed as physical, chemical, and pathophysiological relationships between a drug and a nutrient. This reaction is multifactorial. The drug has the potential ability to interact with nutrients which may lead to a reduction or enhancement of therapeutic efficacy, nutritional risk, and drug toxicity. Even such interactions lead to the discontinuation of drug therapy. But these kinds of interactions vary from person to person. Infants and children are the most vulnerable group in this concern as they are in the developmental phase where there is a lack of proper drug-metabolizing enzymes and inefficient renal function. Generally, DNIs signify negative impacts on human health but sometimes these interactions work in a positive way by reducing irritation in the GI tract or by increasing the absorption of drugs. Proper updated knowledge about DNIs is important for the appliance of diet therapy simultaneously with drug therapy as both of these are important strategies to manage or treat public health issues (Table 10.1., Table 10.2.).

Agro processing involves a diverse range of unit operations aimed at converting raw agricultural products into value-added goods. These processes serve to enhance the shelf life, quality, and overall appeal of agricultural commodities while also boosting their nutritional content and market value. The unit operations employed in Agro processing are determined by the specific characteristics of the product and the desired outcome. Common steps include cleaning, sorting, peeling, grinding, and milling. Preservation methods such as blanching, fermentation, drying, and freezing play a crucial role in preparing products for consumption or further manufacturing. Furthermore, operations like extrusion, canning, juicing, and packaging are essential for producing a variety of processed food items, while proper storage and warehousing ensure the long-term availability and sustainability of these goods. Each unit operation is designed to contribute toward creating high-quality, market-ready products, minimizing waste, and ensuring optimal utilization of raw materials. By combining these processes effectively, Agro processing maximizes the potential of agricultural resources and strengthens the overall food industry.
OVERVIEW OF MATERIAL HANDLING
Materials handling encompasses a broad spectrum of activities, including mechanical harvesting on farms, transportation of live animals, refrigerated transport of perishable goods, and pneumatic conveying of flour from rail cargo to bakery storage facilities. It is important to minimize product losses during these operations while maintaining the quality of raw materials, such as preserving vitamin content and physical appearance, ensuring sanitary conditions, reducing bacterial growth, and optimizing the timing of transfers to avoid delays that could compromise both the economy and product quality. The journey of agricultural produce from farms to processing areas often results in significant transformations. For instance, grapes are transported via tractors, trucks, or trailers to juice plants or wineries, where they are graded, washed, and processed further. However, there are limitations on the size of transport vehicles and the duration fruits and vegetables can be held. Since these are living, respiring products, prolonged storage can increase batch temperatures to levels that encourage spoilage.

Fruits and vegetables are more perishable and generally have a higher value compared to cereals, making them very important in terms of minimizing waste and improving employability in the food industry. The losses in fruits and vegetables are significant, but through effective post-harvest processing, these losses can be reduced, and surplus produce can be better utilized. This processing involves a variety of techniques that prepare fruits and vegetables for conversion into processed foods. The food preservation and processing industry has evolved from being a luxury to an essential sector, playing a crucial role in conserving and enhancing the utilization of fruits and vegetables. To prevent waste during peak seasons and ensure availability during off-seasons, modern methods of storage and processing are necessary. These techniques allow for both large-scale and small-scale processing, extending the shelf life of produce for better distribution. The ultimate goal of food processing is to apply systematic techniques to preserve, process, package, store, and distribute food in a way that ensures a steady supply of diverse and nutritious food options, thereby improving food intake and nutritional standards, particularly during periods of low availability.
For effective preservation and processing, key prerequisites include cleaning, grading, and sorting the produce based on its maturity level. This ensures that only the highest quality fruits and vegetables are used in the processing chain, maintaining food safety, nutritional value, and consumer acceptability throughout the year.
CLEANING OF AGRICULTURAL COMMODITIES
Blanching is a unit operation used in food processing to remove contaminating materials from food and prepare the surface for further processing. In vegetable processing, blanching serves the additional purpose of cleaning the product. This process involves briefly exposing the food to heat, typically by immersing it in hot water or steam, which helps to remove dirt, enzymes, and microbial contamination. By doing so, blanching not only improves the quality of the food but also prevents microbial growth during storage or delays in processing. This early removal of contaminants ensures that the remaining bulk of food is preserved and remains safe for consumption throughout its shelf life.

The operation and maintenance of dehusking, dehulling, degerming, and drying equipment are crucial in ensuring the efficiency and longevity of these machines in grain and seed processing industries. These machines play a vital role in removing husks, hulls, and germs from grains, as well as reducing moisture content to enhance storage stability. Proper handling and regular maintenance not only improve performance but also reduce downtime and operational costs. Dehuskers are used to remove the outer husk from grains like paddy and millet. Their efficiency depends on factors such as roller pressure, feed rate, and machine alignment. Routine maintenance involves checking for wear and tear on rollers, adjusting pressure settings, and ensuring that all moving parts are well-lubricated. Similarly, dehullers remove the outer shell of seeds and grains, requiring careful calibration to avoid excessive grain breakage. Blade sharpness, motor performance, and sieve integrity should be regularly inspected to ensure optimal functioning. Degermers are employed to separate the germ from the endosperm in grains like maize. This process enhances the shelf life of processed products and improves their quality. Regular maintenance of degermers involves inspecting the abrasion plates, checking the feed rate, and ensuring that airflow mechanisms are clear of obstructions. Any malfunction can lead to uneven separation, affecting the final product quality. Dryers are essential in reducing the moisture content of grains to prevent microbial growth and spoilage. They require proper temperature control, uniform airflow, and regular cleaning of heat exchangers and drying chambers. Overheating or under-drying can compromise the grain quality and lead to storage losses. Timely inspections of sensors, air ducts, and burner efficiency help maintain effective drying operations. A well-planned operation and maintenance routine ensures these machines function optimally, increasing productivity and product quality while reducing energy consumption and repair costs.

Rice milling machines are crucial in the rice production industry, as they are used to remove the husk and bran layers from paddy, resulting in polished white rice. Various types of rice milling machines, such as hullers, whitening machines, polishers, and graders, are available, each designed for a specific function in the milling process. When selecting a rice milling machine, it's essential to consider factors such as capacity, efficiency, power consumption, and maintenance requirements. Additionally, the machine’s size should be aligned with the scale of rice production operations. By investing in the right machinery, producers can enhance overall efficiency and product quality, while reducing manual labor and processing time.

OPERATING MECHANISM OF A FLOUR MACHINE
The flour grinding machine operates using blade cutting, high-speed air impact, and a two-layer destruction function that integrates collision and particle sorting. The principle of operation involves the rotor generating high-speed airflow during blade cutting. As the material accelerates within the airflow, repeated impacts cause it to be destroyed in two layers simultaneously, enhancing the destruction rate. As airflow enters the classification chamber, the destruction process rotates at high speed, and the classification rotor generates centrifugal force. The viscous effect of the airflow creates centripetal force. When the centrifugal force on the particles exceeds the centripetal force, the coarse particles return to the destruction chamber, while fine particles are carried with the airflow to the powder collector for collection. There are three primary operating characteristics of the flour mill. First, the main shaft in the power system is sequentially equipped with bearing caps, radial ball bearings, bearing pads, and thrust ball bearings from top to bottom. Second, the grinding system consists of a spring, spring pad, inner grinding head, adjusting nut, and outer grinding head mounted on the spindle. Lastly, the separation system features a brush mounted on the spindle, with a tension spring above and an adjusting nut below the brush. The core principle of the flour grinding process is to reduce grains like wheat, corn, or rice into flour particles. Raw grains are introduced into the mill's hopper and then conveyed to the grinding chamber containing the grinding stones or rollers. As the grains pass through the chamber, the high-speed rotation of the stones or rollers generates friction that crushes, grinds, and pulverizes the grains into a coarse powder, which gradually becomes fine flour. Flour mills are equipped with adjustable settings to regulate the gap between the grinding stones or rollers, allowing for varying flour fineness. This ensures the production of flour suitable for different culinary needs, from coarse flours for rustic bread to fine flours for delicate pastries. The ground flour particles are then

A boiler is a sealed vessel designed to heat water or other liquids, producing steam or vapor for various applications, including heating, power generation, cooking, and industrial processes. The operation of a boiler is similar to that of a pressure cooker but on a larger scale. The steam or vapor generated is used for domestic or industrial purposes, with the system usually involves involving combustion products that heat the water. Boilers come in various types, tailored for specific uses. While domestic boilers are compact and suited for household needs, industrial boilers play an important role in production processes, often operating on a much larger scale. These industrial boilers can be environmentally friendly when powered by natural gas or other low-emission fuels, helping industries reduce harmful emissions while maintaining performance. Industrial boilers have been a part of various sectors for centuries, with applications ranging from steam-powered locomotives to power plants. Their primary benefit lies in their energy efficiency and capacity to generate significant heat, supporting industrial operations. Whether in cooking or running manufacturing plants, heat plays a central role in daily life, and boilers provide a reliable means of delivering it efficiently.

OVERVIEW OF CANNING MACHINERIES
Canning is a food preservation method where selected raw materials are prepared, packed into containers such as tin, glass, or plastic jars, and sealed airtight. The contents are then heated to a sufficient temperature to destroy spoilage and pathogenic agents within the container, followed by rapid cooling to prevent overcooking. Canning extends the shelf life of foods, ranging typically from one to five years, with some products like freeze-dried lentils lasting up to 30 years.
Can Manufacturing Machinery and Equipment
• Can Body Reformer: Can bodies are often supplied collapsed to save space and ease transportation. The can body reformer shapes them into cylindrical forms, preparing them for further processing.
• Flanger: The cylindrical can bodies are flanged by the flanger, which has two flanging dyes. These dyes form grooves at the edges, preparing the cans for sealing.
• Seaming Machine: The seaming machine is used to close the open end of the can. It features a base plate to hold the can and an upper plate that presses the lid onto the can. The machine uses two seaming rollers (first and second) to seal the can tightly.
• Can Leakage Tester: After sealing, the cans are tested for leakage by immersion in water. If any leakage is detected due to improper sealing, it indicates that the can is faulty.
• Flange Rectifier: Cans that have been bent, deformed, or crushed during the flanging process are rectified using the flange rectifier machine, ensuring the cans are in proper shape for sealing.
• Can Coding Machine (Embossing Machine): This machine embosses codes on the cans, which include the product name, manufacturer details, and production date. It ensures proper identification and traceability of the product.c

Packaging machinery is integral to all packaging processes, from primary packaging to distribution packs. It encompasses various stages, including fabrication, cleaning, filling, sealing, combining, labeling, overwrapping, and palletizing.Food packaging refers to the methods, materials, and technologies used to package food items. It serves multiple purposes, such as prolonging the shelf life of products. However, food packaging is not a recent innovation, and its history is quite fascinating. Food packaging has existed in various forms throughout history. The Journal of Agricultural and Food Chemistry highlights that Napoleon played a major role in its development by offering a reward of 12,000 francs for anyone who could invent a method to preserve food for his army. This prize went unclaimed for 15 years until Nicholas Appert introduced the canning method. Appert’s process involved boiling food and sealing it in airtight glass containers, laying the foundation for modern canned food as we know it today.
EVOLUTION OF FOOD PACKAGING THROUGH AGES
The history of food packaging dates back centuries! The Chinese were pioneers in developing paper and wrapping materials, which were utilized for storing food. In ancient Egypt, advancements were made in glass-blowing and molding techniques, allowing glass to be shaped into various forms for food and water storage. Over time, innovations continued to evolve, with figures like Nicholas Appert leading the way. Appert's glass canning method eventually led to the creation of modern metal cans. In the 1880s, the food manufacturer Quaker Oats introduced cardboard cereal boxes as a packaging solution for their oats, further advancing food packaging technology.
Food packaging serves several vital functions beyond simply containing food. Here are Some Key Roles of Food Packaging:
• Preservation: Packaging prevents exposure to air and moisture, which can cause food to spoil quickly. Proper packaging extends the shelf life of food, benefiting manufacturers by reducing waste.

Fruits are an essential component of a human’s healthy diet. Fruits are used as a supplement to primary foods. When compared to grains, many fruits have far greater nutritional potential. The common fig is one of the most important and widely consumed fruits (Ficus carica).

Pre-harvest factors are responsible for the majority of post-harvest losses. Fruits which have already been infected with insects and pathogens, have been poorly irrigated and fertilized, or are of low quality before harvesting will never benefit with post-harvest cures. As a result, the process of accomplishing production quality, as well as harvesting, processing, and selling, must be taken into account.

Most traditional food processing techniques like boiling, cooling, freezing, and blanching are used in a home kitchen. But now-a-days, food processing and preservation industries combine these techniques with other processing operations by using different technical prospects. As a subset of traditional processing technologies, modern processing technologies include hot air sterilization, vacuum cooking and pulsed electric-field technology as well as high pressure treatment, extrusion, microwave processing, and pulsed electric field technology.

Lanolin, commonly known as Wool grease is primarily a lipid secretion from sebaceous glands of wool bearing animals. The role of Lanolin in nature is to protect wool and skin of animal from climate and the environment. It is an excellent emollient, self-emulsifying and dermatological safe for skin applications. Lanolin is a complex matrix since it is a mixture of high molecularweight esters of fatty acids with fatty alcohols, sterols, tri-terpene alcohols; diesters, long-chain alcohols & diols, long-chain fatty acids and hydroxy acids and is therefore difficult for effective matrix clean-up. Because of its water proofing and antimicrobial properties, lanolin is used mainly in cosmetic and pharmaceutical applications.

Fermentation is one of the ancient techniques that been routinely used to maintain the quality of food products. This process involves the breakdown of complex substances like carbohydrates into smaller ones which assist in extending the shelf life of food products. Fermented foods and beverages shared the major portion of the human diet which positively affect the body. Beer is a low alcoholic drink in which malt, hops and other adjuncts like aromatic herbs, honey and others are fermented with yeast to obtain a product that offers unique flavour, taste and aroma (Sohrabvandi et al., 2012).
