Introduction
Understanding the concepts of technology transfer, licensing, and commercialization is crucial as it plays an important role in understanding how scientific discoveries leads to generation of new technologies further making them the impactful solutions that benefit industries and society. In the context of Indian HEIs, this especially important because a large volume of impactful research often remains underutilized due to limited commercialization channels. This chapter explains the terminology, essential components of technology transfer, outlines its significance for the innovation ecosystem. It also outlines the evolution of India’s technology transfer ecosystem, and emphasizes while understanding its potential to boost India’s economy, encourage entrepreneurship, and strengthen global competitiveness. From initial idea to a market-ready product is complex and multiphased process. The stepwise process is shown in Figure 1. It highlights a structured pathway consisting of five core phases: Idea/Concept, Technology development, Intellectual Property (IP) rights, Technology transfer, and Technology commercialisation.
Phase 1: Idea/Concept stage
This process of technology transfer starts with the Idea/Concept phase, where an invention is created. Each phase plays an important role in transforming raw scientific knowledge into innovative solutions that benefit society and generate economic value. In this phase breakthrough ideas emerge, within labs. Researchers explore and develop initial proof-of-concept or prototypes to validate their ideas. At this stage, the focus is primarily on knowledge creation rather than commercialization. This pathway of technology transition is summarized in Figure 1.

a) A Key GDP Contributor: Dairy and Livestock sector form the backbone of agriculture with 28 per cent contribution in GDP and the progress in this sector is dependent on innovative measures to increase the value for farmers as well as customers.

b) Doubling Farmer’s Income : Doubling Farmer’s Income by 2022 can be achieved by improving crop and livestock productivity, efficiency to utilize resources, increased intensity of cultivation and diversification in high value cash crops, processing and value addition of food and animal products. This price realization can be assured through market reforms and efficient market linkages.

c) Unorganised sector – a challenge : The Indian dairy sector is still characterized by strong presence of unorganized sector. Apart from the Cooperative dairy sector, in the last few years there has been a considerable growth in Private Dairy sector and Milk Producers Organization like Maahi in Gujarat. If small dairy farmers are provided with sufficient ‘value addition’ training and support, they can increase their income considerably.

d) Value addition : Further, the milk processing plants can also go for value addition and innovation and in turn pay remunerative prices to milk producers.

Food preservation has evolved from traditional household practices to an interdisciplinary field incorporating microbiology, biochemistry, engineering, biotechnology, packaging, nanotechnology and digital intelligence. The book demonstrates that food stability can increasingly be achieved without excessive reliance on synthetic chemical preservatives. Effective preservation requires control of microbial growth, enzyme activity, oxidation, moisture, temperature and environmental exposure while protecting sensory and nutritional quality. Traditional practices remain scientifically valuable, while thermal, non-thermal, biological, packaging and digital technologies offer new possibilities. Future food systems will depend on carefully designed combinations of these approaches to improve safety, shelf life, sustainability, traceability and consumer acceptance while overcoming cost, regulatory and scalability challenges.

For looking into the biosafety in research laboratories, agriculture and other food producing industries it is important to look into the numerous strains of lactic acid bacteria that are associated with food systems and are capable of producing bacteriocin or antibacterial proteins with activity against foodborne pathogens such as Listeria monocytogens, Staphylococcus aureus and Clostridium botulinum. Recently considerable attention has been given on the identification of these proteins and their biochemical properties including spectrum of activity, production conditions, purification procedures, aminoacid composition and mode of action. Advances in genetic engineering have facilitated the characterization of proteins at genetic level, providing information about protein synthesis, structure and cloning of bacteriocin genes into other organism. One problem in the use of bacteriocin in their applications as bio-preservatives is the emergence of resistant population. The understanding on the mechanism of resistance to bacteriocins is limited which limits the application in biopreservation. Much of the work on bacteriocin has been done under controlled laboratory conditions without the presence of adventitious microbial population. More research is needed to determine the efficacy of bacteriocin producing organisms and bacteriocins which are stable under commercial conditions. Foodborne illness is a major international problem and an important cause of reduced economic growth. The contamination of the food supply with the pathogens and its persistence, growth, multiplication and/or toxin production

A sustainable and healthy food system is one which can provide food and nutrition security for all, in an economical way which is socially and environmentally sound for future generations. Underutilized indigenous and traditional crops can support and strengthen the existing food system, as they are in particular economical and friendly with the environment. Several underutilized indigenous and traditional crops are nutrient dense and adapted to marginal conditions, suggesting that they could be used to champion sustainable and resilient agriculture and food systems for smallholder farmers residing in these environments. The mainstreaming of underutilized indigenous and traditional crops and foods should be recognized for their attributes to make them desirable and to conserve them. In this regard, the fact that value chains for underutilized indigenous and traditional crops are poorly developed at present has created many opportunities to diversify the current food systems. This will create a new employment, market and distribution opportunities.It will also help to combat poverty. It will be if the smallholder farmers and women in rural areas are given the opportunity to utilize underutilized indigenous and traditional crops and re-enter the manistream system. A significant role which is played by the women for the production and conservation of underutilized indigenous and traditional crops offers opportunities for women empowerment through their inclusion in the food system. Promotion of gender equality and empowerment of women is directly linked for strengthening the sustainable food systems that can fight hunger and malnutrition and improve the lives and livelihoods of rural populations. The mainstreaming of underutilized indigenous and traditional crops into the food system would support women to diversify in a sustainable way, feed their own households and to provide nutritious food into the local markets. This will also help in addressing, the Sustainable

Introduction
Storage of fresh meat without microbiological degeneration at temperature more than freezing point of meat is known as ‘conditioning’ or ‘ageing’ and it is said to enhance tenderness and flavor of the meat Conditioning is also known as ageing or proteolysis of meat
• In the initial 24–36 h after the slaughter, glycolysis is the prevailing reaction going on during post-mortem
• The organization of the contractile proteins can only be conserved by the constant supply of ATP (energy source)
• But ATP supply becomes scarce with the passage of time after death and denaturation of the proteins starts
• Denaturation is a physical or intramolecular reorganization without involving hydrolysis of the bonds occurring between the various amino acids of the polypeptide proteins chains
• Denaturation is characterized by heightened reactivity of different chemical groups, a modification in molecules shape or size, reduced solubility and lost biological reactivity in cases of enzymes or hormones
• In the course of post-mortem conditioning, proteins are prone for denaturation due to lower pH than in-vivo, temperatures more than 25 °C or less than 0 °C, dehydration and higher non- hysiological salt levels
• Connective tissue proteins such as collagen and elastin do not undergo denaturation during conditioning

Confectionery fills an especially direct need; the sugar of agreeableness joined with exquisite flavors, smells and mouthfeel affects a basically transitory feeling of thriving and joy. Sugar confectionery has been made all through the long haul with extending headway and it remain alive in unlimited plans following a changed levels of agreeableness, flavors just as scents, feel, appearance and tastes

Sugar confectionery and chocolate includes candies (sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of sugar confections. The words candy (US and Canada), sweets (UK and Ireland), and lollies (Australia and New Zealand) are common words for the most common varieties of sugar confectionery. Confectionery depends on numerous ingredients which have been discussed in detailed in this chapter

Introduction

Women entrepreneurship in economic development of any nation has been recognised for its significant contribution. The women folk can be considered as backbone of any nation. Now time has come for women empowerment. In rural Odisha, women not only play an important role for agricultural development but also plays significant role in allied agricultural sector such as dairy, fishery, poultry, mushroom production etc. In Indian condition dairy has been considered as “Rural Banking” as it is practiced mostly by majority of the marginal, small and landless farm families for their sustenance and livelihood. The role of rural women for animal husbandry is of paramount importance. In this sector they are managers as well as decision makers. Women do more than 80% dairy operation like cleaning, feeding, milking, marketing of milk and milk products. The state and central government initiate several scheme, programmes and projects for empowerment of women through various micro enterprises including dairy. Against this background a study was undertaken to identify the constraint faced by women entrepreneur in dairy sector in Khordha district of Odisha.

The design and structure of a warehouse should facilitate proper ventilation, temperature control, and protection from pests. This includes features like smooth floors, durable walls, and proper drainage systems to prevent water accumulation. The warehouse should also be insulated to protect stored goods from extreme temperatures and humidity fluctuations.
Regular maintenance is essential to keep the warehouse in good condition. This involves routine checks for structural integrity, such as inspecting for cracks, leaks, or signs of pest infestation. Equipment like ventilation fans, conveyors, and lighting should be regularly serviced to ensure optimal functioning.
Sanitation and hygiene are equally important in preventing contamination and pest issues. The warehouse should be thoroughly cleaned to remove any dust, dirt, or residues that could harbor pests or mold. All surfaces, including walls, floors, and storage bins, should be disinfected regularly. Proper waste disposal systems should be in place, and areas where food products are stored should be kept free from garbage or organic waste that could attract pests. Ensuring a clean and well-maintained warehouse helps preserve the quality and safety of stored goods.
SELECTION OF STORAGE TYPE
Some basic Guildelins or Principles are Given as Follows:
ROUND OR RECTANGULAR STORAGE
In terms of structural cost per tonne of storage, round storage buildings are generally more cost-effective than rectangular ones. The reasons for this are straightforward:

Introduction

India’s rural economy has benefited greatly from the dairy sector. It has played a significant role in bringing about socioeconomic change. India’s dairy industry has undergone significant change as a result of the White Revolution. The “White Revolution” can be credited with increasing milk availability and providing rural India with a stable source of employment and income. The business has drastically changed to meet India’s increasing demand for milk and milk products. India is currently the world’s greatest producer of milk. The Operation Flood Program is credited with this title. The dairy market in India is projected to increase at a compound annual growth rate (CAGR) of 6.61% from 2024 to 2029, from an estimated US$26.11 billion in 2024 to US$35.96 billion by 2029 (Indus Food, 2024). With over 8 crore farmers employed and a 5% national GDP contribution, the dairy industry in India is vital to the country’s economy. With around 25% of the world’s milk supply and a massive livestock population of 536.76 million animals, it tops the world in milk production. With major markets in the United Arab Emirates, Saudi Arabia, the United States, Singapore, and Bhutan, India exports approximately 63,738.47 metric tonnes of dairy products in 2023–2024, generating US$ 272.64 million.

Microbial contamination sources: Foods may be contaminated by microorganisms at any time during harvest, storage, processing, distribution, handling, or preparation. The primary sources of microbial contamination are soil, air, animal feed, animal hides and intestines, plant surfaces, sewage, and food processing machinery or utensils. Since most foods either carry or eventually acquire bacteria, molds, or yeasts, microorganisms are the major causes of food spoilage. The increased load of microorganisms leads to rapid spoilage.

Organisms: Bacteria and fungi (yeasts and molds) are the principal types of microorganisms that cause food spoilage and food- borne illnesses. The typical microorganisms that cause food spoilage are bacteria (e.g., Pseudomonas), yeasts (e.g., Candida), and molds (e.g., Rhizopus). The growth of microorganisms in the food will increase the load of microorganisms, and the heavier load will add to the difficulty of preventing spoilage and may influence the kind of spoilage to be anticipated.

Food spoilage may be defined as any change that renders food unfit for human consumption. These changes may be caused by various factors, including contamination by microorganisms, infestation by insects, or degradation by endogenous enzymes (those present naturally in the food). In addition, physical and chemical changes, such as the tearing of plant or animal tissues or the oxidation of certain constituents of food, may promote food spoilage. Foods obtained from plant or animal sources begin to spoil soon after harvest or slaughter. The enzymes contained in the cells of plant and animal tissues may be released as a result of any mechanical damage inflicted during postharvest handling. These enzymes begin to break down the cellular material. The chemical reactions catalyzed by the enzymes result in the degradation of food quality, such as the development of off- flavours, the deterioration of texture, and the loss of nutrients. The enzymatic changes in foods are desirable to some extent as in the case of ripening of fruits, but continued enzymatic activity beyond an optimum point becomes food deterioration due to rotting. The native enzymes may be inactivated by heat, radiation or by the use of specific chemicals.

Tea as a Beverage

Tea is the most popular beverage consumed in the world after water. All types of teas including black. green, oolong, white and pu-erh tea are mainly made from the buds and young leaves of tea plants, Camellia sinensis (L.) O. Kuntze belongs to the family Theaceae [1]. Depending on the different processing techniques of tea leaves, tea types are categorized as “Green Tea” (unfermented), “Black Tea” (fully fermented), “Oolong Tea” (partially fermented), “Pu-ErhTea” (post fermented) and white tea (unfermented) [2]. The manufacturing process for these different types of teas mainly differ in the degree of enzymatic oxidation (fermentation) process [1].

Introduction

Coffee is a beverage made from the roasted and ground seeds of the African tropical evergreen coffee plant. Coffee is one of the world’s three most popular beverages (together with water and tea), as well as one of the most profitable international commodities, and it is the world’s second most marketed product after petroleum (Myhrvold, 2021).Coffee is a popular beverage that is enjoyed around the world for its taste, health benefits, and ability to enhance physical performance (Simkin, 2008).

16.1. CANNED FOODS-PRESERVATION

Canning is a method of preserving food from spoilage by storing it in containers that are hermetically sealed and then sterilized by heat. The process was invented after prolonged research by Nicolas Appert of France in 1809, in response to a call by his government for a means of preserving food for army and navy use. Appert’s method consisted of tightly sealing food inside a bottle or jar, heating it to a certain temperature, and maintaining the heat for a certain period, after which the container was kept sealed until use. It was 50 years before Louis Pasteur was able to explain why the food so treated did not spoil: the heat killed the microorganisms in the food, and the sealing kept other microorganisms from entering the jar. Samuel C. Prescott and William Underwood of the United States set canning on a scientific basis by describing specific time-temperature heating requirements for sterilizing canned foods.

Most vegetables, fruits, meat and dairy products, and processed foods are stored in tin cans, but soft drinks and many other beverages are now commonly stored in aluminum cans, which are lighter and do not rust. Aluminum cans are made by impact extrusion; the body of the can is punched out in one piece from a single aluminum sheet by a stamping die. This seamless piece, which has a rounded bottom, is then capped with a second piece as its lid. The tabs used in pop- top cans are also made of aluminum. Bimetal cans are made of aluminum bodies and steel lids.

Canneries are usually located close to the growing areas of the product to be packed, since it is desirable to can foods as quickly as possible after harvesting. The canning process itself consists of several stages: cleaning and further preparing the raw food material; blanching it; filling the containers, usually under a vacuum; closing and sealing the containers; sterilizing the canned products; and labeling and warehousing the finished goods. Cleaning usually involves passing the raw food through tanks of water or under high- pressure water sprays, after which vegetable or other products are cut, peeled, cored, sliced, graded, soaked, pureed, and so on. Almost all vegetables and some fruits require blanching by immersion in hot water or steam; this process softens the vegetable tissues and makes them pliable enough to be packed tightly, while also serving to inactivate enzymes that can cause undesirable changes in the food before canning. Blanching also serves as an additional or final cleansing operation.

10.1 CEREALS AND CEREAL PRODUCTS

CONTAMINATION: The sources of contamination in cereals and cereal products are soil, insects, air, etc. Most of the microorganisms are removed with the outer portions of the grain during milling. The bleaching agents used during milling also reduce numbers of microorganisms. The bacteria in wheat flour include Bacillus, Micrococcus, Flavobacterium. Mold spores are chiefly of Aspergillus spp and Penicillium spp and in addition Alternaria, Cladosporium and other genera are found. The numbers of microbes in cereals and cereal products vary widely from few hundred per gram to million. Corn meal contains several hundred to several thousand bacteria and mold per gram.

14.1. EGGS

India is the third largest producer of eggs. Fresh eggs are gathered on automatic collection belts at the farm and stored in a cooler at about 7°C. The eggs are then delivered to a central processing plant, where they are washed, sanitized, and graded. Grading involves the sorting of eggs into size and quality categories using automated machines. Flash candling (passing the eggs over a strong light source) detects any abnormalities such as cracked eggs and eggs containing bloodspots or other defects. Higher-grade eggs have a thick, upstanding white, an oval yolk, and a clean, smooth, unbroken shell.

14.1.1. Eggs Contamination

More than 90 percent of all eggs are free of contamination at the time they are laid; contamination with Salmonella bacteria and with certain spoilage organisms occurs essentially afterward. They become contaminated by faecal matter from the hen, by the lining of nest, by handling, by wash water and packing materials. The total number of microorganisms per shell of a hen’s egg was found to range from 100 to 10,000,000 with a mean of about 100,000. Proper washing and sanitizing of eggs eliminates most Salmonella and spoilage organisms deposited on the shell. The organism Salmonella enteritidis, a common cause of gastroenteritis (a form of food poisoning), has been found to be transferred through the hen ovary in fewer than 1 percent of all eggs produced. Ovarian- transferred S. enteritidis can be controlled by thorough cooking of eggs (i.e., until there are no runny whites or yolk).

13.1. CONTAMINATION

MICROFLORA: The flora of living fish depends upon the microbial contents of the waters in which they live. The slime in the outer surface of the fish contain bacteria of the genera: Pseudomonas, Alcaligenes, Micrococcus, Flavobacterium, Corynebacetrium, Bacillus, Sarcina, Serratia and Vibrio. The same species of bacteria are found in shrimps, crabs, lobsters and similar sea foods. Oysters and Shell fish that pass large amount of water through their bodies, pick-up soil and water microorganisms in this way including human pathogens. Common spoilage microorganisms of fish include species of Pseudomonas, Moraxella, and Acinetobacter, found mainly in marine fish, and Bacillus and Micrococcus, found in freshwater fish. Fish may also contain pathogenic (disease-causing) microorganisms such as Salmonella and Escherichia coli. Pathogenic contamination is of special concern with mollusks because they are often eaten raw and as whole animals.

SOURCES: Boats, boxes, bins, fish houses and fishermen are the sources of contamination of these bacteria. The bacterial population ranges from few hundred to few million per square centimeter. Because of their soft tissues and aquatic environment, fish are extremely susceptible to microbial contamination. At the time of harvest, fish carry a high microbial load on the surface of their skin, in their intestinal tract, and in their gills. The type and number of microorganisms that live in fish vary according to the season, the species, and the natural habitat. Additional contamination may occur during the harvesting, handling, or processing of the fish. Harvested fish must be immediately stored in a low-temperature environment such as ice or refrigerated seawater. This chilling process slows the growth of microorganisms that live in fish and inhibits the activity of enzymes. Because fish have a lower body temperature, softer texture, and less connective tissue than land animals, they are much more susceptible to microbial contamination and structural degradation. If immediate chilling is not possible, then the fish must generally be sold and eaten on the day of the harvest.

11.1. FRUITS-Maturation, Ripening and Storage

Fruits are natural foods containing substantial quantities of essential nutrients and the best sources of minerals like sodium, potassium and magnesium, vitamins (antioxidants), such as vitamin A, C and enzymes. They are rich in fructose and water. Fruits are living biological entities that perform a number of metabolic functions. Two functions of particular importance in fruit processing are respiration (the breaking down of carbohydrates, giving off carbon dioxide and heat) and transpiration (the giving off of moisture). Senescence is the period when chemical synthesizing pathways give way to degradative processes, leading to aging and death of tissue. Fruit ripening is thus the result of many complex changes, some interactive but many independent of one another. Once the fruit is harvested, respiration and transpiration continue, but only for as long as the fruit can draw on its own food reserves and moisture. It is this limited ability to continue vital metabolic functions that defines fruit as perishable.

CONTAMINATION

The healthy inner flesh of meat contains few or no microorganisms, although they have been found in lymph nodes, bone marrow and intestine. Staphylococcus, Streptococcus, Clostridium and Salmonella have been isolated from lymph nodes of red meat animals. During slaughtering the lymph nodes are removed from edible parts. The important contamination, however comes from external sources during bleeding, handling and processing. During bleeding, skinning and cutting the main sources of microorganisms are from the exterior of the animal- hide, hoof and hair and the intestinal tract. The exterior of the animal harbours large number and many kinds of microorganisms from soil, water, feed and manure as well as its natural surface flora.

Knives, cloths, air and hands and clothing of workers can serve as intermediate sources of contamination. During handling and processing the contamination can come from containers, air, other contaminated meat, equipments and personnel.

Molds that grow on the surface of the meat include the species of Cladosporium, Sporotrichum, Geotrichum, Mucor, Monilia, Penicillium and Alternaria. The important bacteria found in meat are Staphylococcus, Sarcina, Streptococcus, Clostridium, Leuconostoc, Lactobacillus, Proteus, Flavobacterium, Bacillus, Streptomyces, Escherichia and Salmonella.
