Introduction

Fruits and vegetables are essential constituents of daily diet and are highly demanded in the recent years from most of the population. They are reservoir of vitamins, essential minerals, antioxidants, bio-flavonoids, dietary fibres and f lavour compounds which fall easily victim to abiotic and biotic adversities. Fruits and vegetables are highly perishable and during the post- harvest, there are considerable losses due to microbes, insects, respiration and transpiration.

The important quality factors of fresh produce contributing to the marketability are texture, colour, appearance, flavour, nutritional value and microbial safety. These quality factors are measured by plant variety, ripening stage, maturity stage pre-harvest and post-harvest conditions. The Post-harvest losses of fruits and vegetables are a serious problem because it rapidly deteriorates them during handling, transport and storage. Edible coating over fruits and vegetables are used to improve their quality and shelf life.

Pineapple (Ananas comosus) is an edible fruit bearing plant native to South America belonging to family Bromeliaceae. Pineapple is grown over an area of 1.06 million hectares with an annual production of 29.36 million metric tonnes (FAO, 2022). Pineapples are rich in vitamin C, minerals, fiber and low in calories. The enzyme bromelain present in pineapple is of considerable importance to the pharmaceutical and cosmetic industry (Varilla et al., 2021). The market for pineapples has been expanding significantly because of its appealing aroma compounds and nutritional benefits. The climate and distribution of rainfall in tropical and sub-tropical regions make these areas ideal for pineapple cultivation. Worldwide, Brazil is the leading producer of Pineapple followed by Philippines, Thailand, Costa Rica and India (FAO, 2022). In India the leading pineapple producing states are West Bengal, Northeastern region, Bihar, Kerala, Karnataka, Goa, and Maharashtra.This ‘Kew’ of Cayenne group and ‘Mauritius’ of the rough leaf Queen group are the two varieties dominating in India (Devi et al., 2013; Joy and Sindhu, 2012).

Botanically, Pineapple is a herbaceous perennial having short stem and tough waxy leaves. It produces a fleshy, edible, yellow fleshed which is a fusion of 100-200 berry like fruitlets. Most of the members of Bromeliaceae family are epiphytes i.e. grown on rocks and living trees though pineapples grow on the soil bearing sensitive adventitious root that cannot regenerate once damage and intolerant to poor soil aeration. The cultivated varieties of pineapple can be categorized into three groups namely, Cayenne, Queen, and Spanish. The Spanish and Cayenne groups can be cultivated for dual purposes viz. fresh fruit and canning. However, the Queen group are only cultivated for fresh fruit markets due to the presence of deep eyes making it unsuitable for canning (Devi et al., 2013).

Abstract

The use of biosensors is growing in the food industry as a means to ensure food safety and quality because of its versatility in determining biological compounds. It is defined as analytical technique used for detection of analyte that combines a biological component with a physico-chemical detector. The most important contribution of biosensors in the food sectors is to control production processes and ensure food quality and safety by reliable, fast and cost effective procedures. Biosensors have been useful for the evaluation of food composition, particularly in functional food products fortified with phytochemicals, vitamins and minerals.. Biosensors are replacing conventional analytical tools since they offer advantages in size, cost, specificity, rapid response, precision and sensitivity. Future progress in the biosensor technology involves the development of nutraceutical release technology within packaging material where it can be used to trigger the controllable release of bioactive components and targeted delivery of protective agents into the food product. The growing consumer demands for safe and quality food has led the food industries to search for quick and reliable methods for which the applications of the biosensor technique in the field of food processing and quality control are found to be promising.

Strategic partnerships and productive outreach play a crucial role for new technologies to successfully reach the market, drive growth, and strengthen a country’s global competitiveness, Outreach programs have various benefits, ranging from technology transfer awareness, communication of stakeholders, industry, government, to academy partnership promotions. These efforts help in establishing connections, communicating opportunities, and encouraging active engagement from key stakeholders. Outreach activities can be performed under two broad categories:
1. Written communication includes all communication which can be viewed, shared, or made accessible for a set of people in a passive manner. This includes reports, newsletters, guidance, and online content which provide insights of worth for stakeholders.
2. Human outreach includes all direct communication like c face-to-face or verbal form communication it included conferences, conventions, workshops, seminars and personal communication with industry leaders.
The type of outreach creates stronger, more personal connections. An effective outreach strategy usually combines both human and written outreach efforts. By following this strategy TTOs can expand and strengthen partnerships, and make it easier for research-led innovations to get transition from lab to market more effectively. This chapter explores key outreach models, strategic networking approaches, and proven practices for building impactful partnerships in technology transfer.

Introduction

Carbohydrates are the most common source of energy for all living cells, which, in presence of light, are formed by the green plants from CO₂ and water during photosynthesis. It canbe said that ‘light’ is theultimatesourceof energyrequired for all livingcells.Glucose,a monosaccharide,plays a centralroleincarbohydrate metabolismin all plants, animals and manymicroorganisms. Glucose is derived from the polysaccharides (starch, glycogen) and non-carbohydrate sources (amino acids, glycerols, etc.) during metabolism and ultimately converted either into carbondioxide and water orotherintermediateproducts.Complete oxidation of glucose to CO₂ and water provides ~2,840 kJ/mol energy. The other monosaccharides such as fructose, galactose, mannose, etc. are also important molecules in carbohydrate metabolism.

8.1 Key legal statutes and regulatory foundations
Various policy measures were also undertaken by the Government of India in due course of time. The Government of India enacted four science policies after gaining independence, i.e. Scientific Policy Resolution (1958), Technology Policy Statement (1983), Science and Technology Policy (2003) and Science Technology and Innovation Policy (2013). The 1983 Technology Policy Statement possessed a simple goal of creating indigenous technology and boosting efficient absorption and adaptation of imported technologies suited to the nation’s priorities and. The Technology Policy Statement of 1983 was followed up through the establishment of the Technology Information Forecasting and Assessment Council (TIFAC), an autonomous organization entirely owned by the Government of India under the Department of Science and Technology during 1988. TIFAC also offers some funding and supports development and commercialization of technologies through the home-grown technology scheme, among its other operations. The Technology Development Board Act (1995) was also a significant policy move of the government in the same direction. Also in recent times, the Government of India also unveiled its own National IPR Policy 2016 with the motto cum slogan “Creative India, Innovative India”. In addition, the policy is aligned to a number of other schemes of the Indian Government like “Make in India”, “Atal Innovation Mission”, “Start-Up India” and “Stand-Up India”, all aimed at encouraging creativity, innovation and entrepreneurship in the nation.

Introduction

Color is an important characteristic of food. Based on the color of the food, f irst impressions are made: Is the fruit immature, ripe, or overripe? Is the toast burnt? Is the food fresh? Based on these first impressions, a judgment is made whether the food is safe to eat or not and whether it can be expected to taste good or not. Since color is closely associated with expectations, the addition of color to food is a way to fulfill these expectations. Color is added to food for one or more of the following reasons:

1. To replace color lost during processing,

2. To enhance color already present,

3. To minimize batch-to batch variations, and

4. To color otherwise uncolored food.

Introduction

Nutrition, a basic human need, is a critical part of health and development. Nutrition can be defined as the intake of food, deliberated in relation to the body’s dietary needs. On one hand, good nutrition – an adequate, well balanced diet combined with regular physical activity – is a foundation of good health, whereas,poor nutritionleads toreducedproductivity,impairedmental andphysical development, increased susceptibility to disease, and reducedimmunity. According to WHO, under-nutrition, together with vitamin and mineral deficiencies accounts for one-third of all child deaths and impairs healthy development and lifelong productivity. At the same time, sedentary lifestyles, demographic shifts, urbanization and the liberalization of markets have steered the world population to being overweight along with risk of chronic diseases like hypertension, dyslipidemia, type 2 diabetes, coronaryheart disease, stroke, etc.; thus, resulting in a double burden of malnutrition.

To address this dual burden of malnutrition, individuals needaccess to sufficient and good quality food; but focussing solely on food security is unlikely to solve the problem of global malnutrition. The challenges of malnutrition cannot be solvedjustbyincreasingfoodproductioninordertoimprove healthand nutritional status of the population. To resolve such challenges, awareness about food choices for optimal health plays a pivotal role among population.

Human nutrition is the science of understanding food; its component; intake; and how it is related to health, growth, development and diseases. Human nutrition involves the study of ingestion, digestion, absorption and assimilation of the nutrients; their metabolic functions, deficiency or excess disease as well as their regulation through several factors such as choosing particular food components/nutraceuticals or physical activity.

Introduction

How one can differentiates between sensory science and sensory evaluation? Perhaps the simplest way would be to think of sensory science as the fundamental physiological and psychological underpinnings of sensory evaluation. It could include our basic understandings of the mechanisms of taste and odour, kinesthetic and the various techniques of scaling and statistical analysis, whereas, sensory evaluation could designate the application of this knowledge and the development of specific methods for the evaluation of the discriminative, descriptive and affective nature of products, in a problem-solving situation. When the quantitative descriptive analysis (QDA) methodology was f irst described, it represented a decade of experimentation and study of the issue that were perceived at the time to be impediments to solving “the problem of flavour characterization” (Stone et al., 1974). As noted by Pangborn (1964), new developments and knowledge about sensory evaluation were beginning to have a positive effect on its acceptance by industry, but much more needed to be done if it was to contribute in a meaningful way. Today, it is indisputable that flavour is an important attribute affecting consumer acceptance of food. “Flavour is taste plus odour”. The perception of taste is merely the detection of non-volative tastants by the tongue. On the other word, the perception of odour is the detection of odoriferous volatile aroma compounds by the olfactory nerves ending in the nose. The combination of all possible flavour stimuli we could encounter is as vast as the galaxy. However, most of the attempts to define these experiences have historically been over simplified.

13.1 Challenges in the technology transfer process
Technology transfer (TT) is more complex and involves the complex interrelationships between universities, research institutes, the private sector, the state, and society. Though TT is all about translating research findings into purposeful solutions that can support the economy and society, it is not a linear process. The challenges can be described as legal, institutional, cultural, financial, policy, and human resource. All this is accompanied by bottlenecks that inhibit or decelerate the diffusion of promising technologies.
13.1.1 Legal and intellectual property challenges
The vital component of technology transfer is the proper management of intellectual property (IP), which is often the most challenging aspect.
• Ambiguities in IP ownership: During multi-institutional or shared funder research, ownership is quite controversial. As an example, when a government lab and a university collaborate on the project, there is ambiguity as to who would have the ultimate licensing authority over the technology: the university, the lab, or the funding agency. This kind of fight hinders commercialisation and scares off industry partners.
• Lengthy patent filing and prosecution timelines: In several jurisdictions, the filings, examination, and granting of a patent may take between three and five years or more. Such delay is not compatible with the rapid cycle of invention in other fields such as ICT or biotechnology, where patent claims may become invalid before they are granted.
• High costs of IP protection: International direct patenting, like under the Patent Cooperation Treaty (PCT), is costly and involves legal services, fees, and upkeep costs. These costs are excessively high, which cannot be easily compensated by universities and startups, and where technologies are not secured or limited to local markets.

Introduction

Digestion may be defined as the hydrolytic process carried out by various enzymes for breaking down complex food components such as proteins, fats and carbohydrates into simpler molecules like amino acids, fatty acids and monosaccharides, respectively. Whereas, absorption may be defined as the movement ofthese simple soluble digested food componentsalongwithvitamins, minerals and water from gastrointestinal track into the circulatory system.

The process of digestion starts from oral cavity (mouth) and ends at large intestineincluding tongue, teeth, jaws,secretions from salivaryglands (parotids, sub maxillary or submandibular and sublingual glands), pharynx, esophagus, stomach, small intestine and digestive enzymes secreted from pancreas and liver.

Galactan : It is a polysaccharide in which major monosaccharide subunit is galactose and often found among the pectic substances of cell walls.

Galactoblast : It is also called colostrums. It is female’s first milk after parturition.

Galactometer : It is an instrument used for recording the specific gravity of the milk.

Galactorrhea : A spontaneous flow of milk from the nipple is called galactorrhea.

Introduction

Canning is the general term applied to the process of packaging a food in a container and subjecting it to a thermal process for the purpose of extending its useful life. An optimal thermal process will destroy pathogenic (disease-causing) Bacteria, kill or control spoilage organism present and have mineral impact on the nutritional and physical quality of the food. Although we thing of canning in term of steel or possible aluminium cans, the principle apply equally well to a variety of food containers such as glass jar, plastic and foil laminated pouches, semi rigid plastic tray or bowls, as well as metal cans of any one of several shapes, including cylindrical, oval, oblong or rectangular. The concept of aseptic packaging (sterilizing the food and the container prior to filling and sealing) also follows the same principles.

Introduction

Thermal processing is an important treatment for food preservation is, especially in the manufacture of shelf-stable foods with specific nutritional properties. It is also indispensable for determining the sensory properties, particularly, colour, flavour, and texture of fried, baked, and roasted products. As a result of heat treatment, chemical changes induced, and a plethora of new molecules are formed in foods, some of which have been claimed to be health-promoting antioxidants and anti-mutagens. However, reports suggest that thermal processing leads to the formation of certain toxic compounds, so-called process-induced contaminants in foods. The process-induced toxicants are certain compounds which are formed in food as a result of food processing, exert adverse toxicological effects, and cause potential health risks to humans. Acrylamide, furan, chloropropanols, heterocyclic aromatic amines, polycyclic aromatic hydrocarbons, and N-nitrosamines are some well-known examples of thermal process contaminants.

Traditionally, Labour Laws have a protective function consisting of established standards both to protect workers in their workplace and to provide them a basic minimum level of living conditions. Alongwith this function, there also existed in most systems, a legal framework for the regulation of industrial relations between employers and workers. These functions had their impact on problems of development. The emphasis was more on labour legislation for its own sake, development being a separate proposition. This mutual lack of concern was perhaps due to historical factors. The most important aspect is the fact that in developed countries of the Western world, labour legislation followed the emergence of industrialization and in response to a demand for economic and social betterment of the workers, whereas in developing countries the emergence of labour laws preceded industrial growth.

Introduction

The hilly states in north eastern India are not only famous for their forest wealth and awesome wild assets. These states are also known for their track record in harvesting specific crops and fruits. Some of the iconic ones are like, “Assam tea” which is famous in and outside India and popularity of “Khasi mandarin” is also well known. The small landlocked state Tripura produces quality pineapples in abundant amounts, where cv. Queen is popular among the growers. Sikkim and other states of north eastern region of India is known for their Organic Farming techniques, which is mostly attributed the nature of hill farming on this region. North-East is rich in horticultural aspect viz., f loriculture with a rich variety of medicinal plants grown there along with various fruits and vegetables. An analysis of NSSO survey data on cultivation practices shows that the North-East hill states have retained traditional practices and show an inclination towards organic agriculture that is harnessed for the development of the region with ecological benefits.

The demand of day by day increasing population there is lacking of nutritious food to peoples all around world. Underutilized crops like small or minor millets are having more nutrition and providing calories up to 2000 to 3000 calories per person per day than our staple crops i.e wheat, rice, and maize etc. Small Millets are the most underutilized crop in the world possessing high nutrient-cereal qualities and potential for the improvement of food security, nation income and generate the employment for the rural peoples. Millets are rich in nutrients such as proteins, fibers, carbohydrates, fats, vitamin-B, and minerals like calcium, phosphorus, magnesium, iron, potassium, and zinc etc.They are highly nutritive crop, non-acid forming, glutan free and help in reducing blood sugar level, blood pressure, diabetes and cardiovascular diseases. They also help in preventing asthma and migraines sufferings and fighting malnutrition in children s and adults.S mall millets are considered the forgotten crop species because of lower yield compared to other millets i.e. Sorghum and Pearl millet and cereals i.e. rice, wheat, maize etc. Being a highly nutritive cereal crop, easy to digest, high fibers and low glycine-max content, environment friendly and prevent the human hazards small millets still remained neglected and underutilized crop. Out of 200 underutilized crops identified 29 are small millets species (NAS USA, ICUC). Considering the food demand of common peoples, emerging health consciousness and nutrient demand for food security emerged small millets to limelight because of ecologically sound to climate. Still, the harvest of crop demands combination of computational technologies to full-fill food needs of population. Recognizing the potential of small millets in improving the national income UN-FAO announced the year 2023 as International Year of Millets. This chapter focused on application of climate smart agricultural methods such as artificial intelligence for the improvement of small millets to achieve future food security.

Introduction

Bread wheat (Triticum aestivum L.) is one of the most widely cultivated and consumed crops in the world. Wheat is perhaps best known for its different end-use baking properties as determined by grain texture, protein content and quality. Wheat is generally traded by and classified into “hard” and “soft” market classes on the basis of grain hardness or texture of the wheat kernel (caryopsis). Soft wheats have softer endosperm texture that fractures easily, therefore requiring less energy to mill, yields smaller particles, and has less starch damage after milling when compared to hard wheats. Hard and soft are used with slightly different connotations in different parts of the world. In Western Europe, hard is applied primarily to durum wheats and the soft applied to bread wheat. Elsewhere the term is applied to different cultivars within the species Triticum aestivum. In general, hard wheats are used for bread baking, while soft wheats are used for cookies and cake making. Hard wheat requires more force to crack the kernel, maintains a larger particle size, passes through sieves more easily and has more damaged starch MacRitchie (1980). Higher starch damage is required for good bread making quality Tipples et al. (1994) but is detrimental to the biscuit making quality.

Ice cream is not only an indulgent frozen dessert but also a food containing several nutrients derived from milk, cream, sugars, and other ingredients. This chapter examines ice cream from a nutritional and food-science perspective, focusing on its major nutritional components and energy contribution. It discusses milk fat, proteins, lactose, carbohydrates, minerals, vitamins, and the nutritional effects of formulation. The chapter also considers energy value, portion size, digestibility, and palatability. Understanding these factors helps explain why ice cream provides both nutritional and sensory value. The discussion provides a balanced foundation for evaluating ice cream as part of varied diets and developing products for different consumer requirements.
