Introduction A functional food is a food that provides alimentative beyond their actual nutritional value & are claimed to have an extra function by the addition of new ingredients or more of already present ingredients into it. Functional food have also become a part of our everyday daily diet & are told to offer potential various health benefits other than the widely accepted nutritional effects among them. (Roberfroid MB 2009). Many bioactive active compounds are contained by them like roughage, OS, vitamins, inorganic elements, & bacterium probiotic, having scented whiff, relish & fineness, which sustain the balance & balance of the enteric system. Functional may also be said as artificer‘s foods, NC, restorative foods, curative food, & super food etc because of the roles & functions they perform. (Wlodzimierz Grajek et al., 2008). There are many utilitarian sequels of functional food & beverages with added bug & probiotics on the health of humans which are increasingly promoted & recommended by the nutritionists & other we-being professionals. (Aditya Chaudhary 2019). For a time being, the most salient & over & over again used functional foods amalgam are probiotics & probiotics, or they altogether called as symbiotic‘. he dwell Microbes or foods microbes, which are beneficial for human, are probiotics. (Armachius James &Yousheng Wang 2019).

Pectin
Pectin is a component of nearly all fruits and vegetables and can be extracted and used in food processing to form the characteristic gel in jams and marmalade. The richest sources of pectin are the peels of citrus fruits such as lime, lemon, orange and passion fruit or the pulp of apple (known as ‘pomace’ after juice has been extracted). Commercially, pectin is available as either a light brown powder or as a dark liquid concentrate. It is stable if stored in cool, dry place and it will lose only about 2 per cent of its gelling power per year.
There are two main types of pectin:
• High methoxyl (HM) pectin that form gels in high solids jams (above 55% solids) in a pH range of 2.0-3.5; and
• Low methoxyl (LM) pectin, which do not need sugar or acid to form a gel, but instead use calcium salts.

1. INTRODUCTION

With diverse agro-climatic conditions, India produces a wide variety of horticultural crops and out of these crops and out of these apple (Malus x domestica Borkh.) occupies a prominent position in India. It is processed into different products like juice, concentrates, wine, cider, canned slices etc. Apple processing is one of the major industries in countries of the world including India, where it is processed in different states like H.P, Jammu and Kashmir and Uttarakhand. Apple pomace is a left-over residue after juice extraction containing peel, seeds and remaining solid parts and represents about 25-35% of the weight of the fresh apple processed. At prasent, it is a waste and its disposal is a major environmental problem (Plate 1). Being precious natural resources its utilization is a challenge and opportunity to the scientists and technologists. It may be a good substrate for the pectin esterase enzyme, animal feed, citric acid, ethanol and biocolour production. It could be a good substrate for the production of microbial colours under SSF which otherwise require a costlier medium for its production. Different products using solid state fermentation of apple pomace forms the subject matter of this chapter. Here the efforts made to utilize apple pomace especially to explore the possibility of making value added products using Solid State Fermentation (SSF) have been summarized.

1. Introduction

There is intense commercial interest in dehydrated fruit and vegetable products especially mango powder, banana powder, orange powder, papaya cereal flakes to powder, tomato juice powder and other vegetable powders, which are in great demand for soups, biscuit type cookies supplemented with fruit powders (Ana Maria et al. 2009; Sunita and Chauhan 2008), pizza mixes and sauces. Natural fruit and vegetable powders are gaining lot of popularity in recent years as they are very easy to handle after production, require minimum storage space and they are attractive. Tamarind powder is developed from tamarind fruit (Tamarindus indica) (Manjunath et al. 1991) and recently cashew apple and guava residues from fruit juice industry were successfully converted into fruit powders and used at different levels of wheat flour substitution for cookies formulation (Ana Maria et al.2009) and fruit puree like papaya can be mixed with cereal flour to prepare slurry and after gelatinization, the slurry can be useful for preparing drum dried flakes and powder (Sunita and Chauhan 2008). Tropical fruits are exotic in flavor but their juices and purees are seldom available in dehydrated powder (James, 1971). Citrus juice concentrates were produced during world war II in powdered form by using spray, drum, vacuum-puff, and freeze drying (USDA, 1962). The preservation of fruits and vegetables by dehydration offers a unique method, which may be considered as an alternative low cost preservation technique. A shift from fresh to more and more processed foods with significant value addition is bound to occur sooner or later considering the socio-economic changes taking place in the country and the rapid integration of Indian economy with global system. Most popular brands are found in the “ready to consume” food sector.

2.1 Soil and Climate

Pomegranate grows well in sandy-loam and well-drained soils having a pH of 7.5. It can also be grown on light soils. Quality and colour development in light soils is good but poor in heavy soils. It tolerates salinity up to 9.00 EC/mm and sodicity 6.78 ESP. Even it can be grown well in slightly saline soils as it is considered a saline-tolerant plant (Patil and Waghmare 1983; Rao and Khandelwal 2001; Ram Asrey et al., 2002). Accumulation of salts, in excess of 0.5% of the soil mass causes dying off of growing roots. Interestingly, application of Paclobutrazol (250 ppm) was reported to reduce salinity damage (Saeed 2005). The presence of water-soluble salts like sulphates and chlorides and ex- changeable sodium negatively affect root formation.

Nutrients are organic and inorganic complexes contained in the food and it is essential for all living organisms for their normal body development. Macronutrients are the key biopolymers such as proteins, carbohydrates and lipids, which are needed in hefty quantities to provide the bulk of the energy while micronutrients (vitamins and minerals) are required in minor levels in the body; however, are indispensable for proper growth and development of living organisms. Food that cannot provide the right blend of energy including high-quality protein, essential fats, and carbohydrates as well as vitamins and minerals definitely impair growth and development, increase the risk of death from common childhood illness, or result in life-long health consequences. Fish and fishery products form a substantial part of human diet, both of poor and wealthy. Seafood is an excellent resource for proteins, vitamins, trace elements and polyunsaturated fat (omega-3 fatty acids). Profiling of nutrients is very much essential due to the ever-increasing awareness about healthy food which finds more acceptance towards the consumption of fish and fish products owing to its special nutritional qualities.

Profitability in the ice cream business depends on controlling costs and protecting value across the complete product journey. This chapter examines both backend and frontend profitability levers, including yield improvement, giveaway control, manufacturing efficiency, OEE, utilities, refrigeration, quality costs, procurement, channel economics, distributor performance, route profitability, freezer productivity, and return on investment. It emphasizes that high sales volume does not necessarily guarantee sustainable profitability. SKU economics, pricing discipline, working capital, cold-chain losses, stock ageing, and trade schemes must also be managed. The chapter presents a structured profitability-improvement approach that connects manufacturing discipline, commercial strategy, operational efficiency, and financial governance to stronger contribution, EBITDA, cash flow, and sustainable business growth.

Introduction

Biotechnology is defined as the ‘application of scientific and engineering principles to the processing of material by biological agents to provide goods and services’. The term ‘biotechnology’ is also used when a technique involving live organisms are employed to make or modify a product, improve plants or animals or develop microorganisms for specific uses. According to the definition of the Codex Alimentarius Commission (CAC 2001), modern biotechnology is defined as the application of (i) in vitro nucleic acid techniques, including recombinant deoxyribonucleic acid (DNA) and direct injection of nucleic acid into cells or organelles, or (ii) fusion of cells beyond the taxonomic family, that overcome natural physiological reproductive or recombination barriers, and that are not techniques used in traditional breeding and selection. Scientific developments of present world owe to processes and products of the field of biotechnology. Modern biotechnological advancements have played a major role in important branches of science such as agriculture, food processing, medicine and veterinary applications. Biotechnological interventions of the downstream processing applications include primary production areas namely breeding of crops and livestock, production of additives for food and feed and pharmaceuticals along with diagnostic tools. Inputs for food processing applications from biotechnology include biocatalysts such as enzymes, tracing food ingredients such as Genetically modified (GM) ingredients in end products of food and feed and food quality testing applications for food borne pathogens. Applications of modern biotechnology in form of genetically modified organisms have gained much importance in comparison to the downstream applications during food processing and food safety (Zhu, 2017). Food processing operations include transformation of harvested crop or animal produce into produce which are marketable with long shelf life and minimises waste and losses of raw produce in food chain and ensure their continuous availability in super market shelves. Food safety is an important area which assures of the food being safe for consumption. Food technological applications of modern biotechnology includes food enzymes that are important in various food processing applications in reactions involving lipids, carbohydrates and proteins, food fermentations to improve properties such as taste, flavour, texture, nutritional and shelf stability, food additives in form of bio preservatives, flavours, fragrances, genetically modified starter cultures, genetically modified crops, modern rapid diagnostic kits for food safety are discussed in detail.

Introduction of Food Industry

India is one of the major food producers in the world. The food sector contributes to about 28% of India's GDP. India stands at 1st position in the world for production of cereals, milk, livestock, banana and Mango, 2nd in producing fruits and vegetables and ranks amongst top 5 in producing rice, wheat, groundnut, tea, coffee, tobacco, spices, sugar and oilseeds. India's share in global production of fruits is 10% and vegetables are 13.7%. The current consumption of fruits and vegetables is approx Rs.2 lakh crores at current prices with an estimated growth rate of 11% per annum. The growth rate is higher than cereals and milk and comparable to meet consumption

Status of Food Processing Industry

The food processing industry in India is still in a sorry state. The rural population comprising 70% including small cities, consume less than 10% of the processed foods and vegetables, whereas 60% of the processed food is consumed in four major metropolitan cities and 30% in the state capitals and big cities. Another fact is that 40% of the processed food and vegetables produced in the country in terms of value are bought by institutional buyers like Hotels, Restaurants and Defense etc. The highest growth in domestic market has been in fruit drinks, tomato ketch up and Jams.

There is another fact that India is the largest milk producer in the world, however, organized industry accounts for less than 15% of the milk produce in India. It is estimated that there may be a total production of 1100 million tons of production of food products mainly food grains, oilseeds, sugarcane and fruits/vegetables during 2011-12 and leaving marketable surplus of 870 million tons.

Sexual Propagation in Pineapple

Pineapple occupy a gametophytic self-incompatibility system so that commercial cultivated pineapple rarely produces very few seeds in the field (Coppens d’Eeckenbrugge et al. 1992). However, if two varieties are grown close together and flowering time is same, it is chance for insect-aided crosspollination to set seeds. The vectors for natural cross-pollination vary with the location. Where humming birds are present, they are likely to be a primary pollinator. Where these birds are absent, honeybees and ants would be the main pollinators. The small corolla tube and the fact that pollen is not shed rule out wind as a pollinator. Since seedy fruit is not acceptable for either fresh or processing, it is rare to find more than one cultivar on large plantations. If more than one cultivaris grown in a farm, spatial separation and careful management of time of forcing will prevent seed production. However, cross-pollination between cultivars is used by pineapple breeders to generate new hybrids like “MD-2” and “CO-2” (Williams and Fleisch 1993). Sexual propagation is important for the generation of new varieties and is successfully used in pineapple breeding programs (Reinhardt et al., 2018). Pineapple Seeds are placed in shallow trays on moistened sand beds under controlled environmental conditions for germination(Junghans et al., 2015).Seed germination come up mostly from two weeks after sowing and rates are high, usually 80% or more (Chang et al., 2003). The new growing seedlings have 6 to 8 leaves stage within about three months after sowing and are then transplanted to pots with agricultural substrate and are grown under greenhouse or screen house conditions. After an additional 9 to 15 months of growth stage, during which the seedlings height reach 25 cm, which is considered adequate for planting in the field, the plants are finally acclimatized in an open nursery.

1. DEFINITIONS

Propagation : Propagation of plants may be defined as the controlled reproduction of plants by man to perpetuate selected individual or groups of individual plants which have specific value to him or it is the perpetuation of plants as independent units by means of seeds, bulbs, layers, cuttings, or grafts.

• Seed: A seed has been defined as a young plant packed ready to start growing when required.
• Apomixis: Development of seeds without the complete sexual process is known as apomixes and seed produced in this manner is called apomictic seeds.
• Seed dormancy: The embryo of the seed remains in inactive stage from the time of its development to the time it germinates. This failure of the embryo is termed as dormancy of the seed.
• After-ripening: Some seeds germinate fully when freshly harvested, but they germinate after a period of dry storage. The change taking place in such seeds are known as after- ripening.
• Embryo dormancy: Conditions existing within the embryo.
• After-ripening dormancy: Seeds fail to germinate when freshly harvested, but they germinate after a period of dry storage. Such seeds are known as after-ripening dormant seeds. This is due to the physiological changes taking place in embryo.

Spices play important roles in daily life and India is a rich repository of spices. Various biotechnological approaches like micropropagation, somaclonal variation, in vitro conservation, synseed technology, protoplast fusion, production of flavor and coloring components, and development of novel transgenics have great significance in conservation, utilization and increasing the production and productivity of spices. Protocols for micropropagation and production of disease free planting materials are available for many spices. Efficient plant regeneration protocols are also available for exploiting somaclonal variation ,where the available natural variability is relatively low. Technologies for isolation and culture of protoplasts were reported in a few spices. Development of transgenics for disease resistance is gaining momentum. Synseed and Micro-rhizome technology are also available for many spices for safe propagation, conservation, movement, and exchange of germplasm. In vitro and cryo preservation technologies for conservation of spices germplasm are available for many spices.

Introduction

Fisheries and aquaculture are important source of food, nutrition and livelihood for millions of people around the world. Aquaculture is the fastest growing food-production sector in the global aquaculture with production of 73.8 Million tonnes in 2014 (FAO, 2016) expanding into new directions, intensifying and diversifying. A persistent goal of global aquaculture is to maximize the efficiency of production to optimize profitability.

Infectious diseases pose of the most significant threats to successful aquaculture. Intensively cultured fish and shellfish are susceptible to infectious agents. The losses due to shrimp diseases in India is valued at Rs. 10, 221 million. Globally, the yield loss due to diseases in aquaculture is estimated to be $ 6 billion. A variety of antimicrobial and chemical treatments have been used for the control and treatment of bacterial diseases in aquaculture systems. The emergence of antimicrobial resistance in bacteria due to application of antibiotics in aquaculture and the toxic nature of chemicals led to the search for alternatives for the control of infection. Here, we discuss the several alternatives to antibiotics that have been successfully used in aquaculture.

1. Introduction Proso millet (Panicum miliaceum (L.) belongs to the grass family Paniceae. It is a perennial cropthat grows in summer each year as late-seeded summer crop (Figure 1). Its origin can be traced back to at least 2000 B.C. when it was said to be grown in the Central European regions. Proso millet plant thrives in dry areas such as Africa, Central Russia, Manchuria, Middle East and Northern India and North America’s Great Plains. Proso millet was introduced to Canada in the 17th century and used sparingly as a feed crop in the early 1900s (Rajasekaran and Francis, 2021). This is a low-demand crop and is utilised in organic farming systems across Europe and as an intercrop in the United States. Its shallow root system and resistance to atrazine residue make it a great intercrop between two crops that need a lot of water and pesticides. The last crop’s stubbles entrap more heat into the soil which promotes faster and earlier growth of millet. Hence, it can help to evade summer drought and achieve continual crop rotation (Kalinova and Moudry, 2006). It is an erect herbaceous annual crop with a lot of tillering. Its plant can reach a height of 45-100 centimetres. The stem is thin, with prominently enlarged nodes. The roots are thin and fibrous.

1.1 Introduction Among the C4 grasses known as panicoids (subfamily: panicoideae), which also includes nutrient-rich cereals like millets and sorghum as well as commercially valuable crops like switchgrass, napier grass, and guinea grass, are bioenergy feedstocks like sugarcane and miscanthus. Among all, millets overpowered others in terms of biotic/abiotic stress resilience, resource sustainability as well as nutritional benefits. Minor millets, often known as nutritional cereals, are a type of small-seeded grains that are members of the Poaceae family. Up to 35 kinds of grass from 20 genera are well-known for being minor millets. Finger millet, foxtail, proso millet, barnyard millet, kodo millet, and little millet are the most significant small millets that are grown worldwide. India is the leading producer and consumer of millet crops and their products. The total area of small millets in India is around 1.63 m ha, with a production of 1.82 m tones during the year 2016- 17 (Annual progress report 2018-19, ICAR-AICRP on small millets).

Like other sectors of the economy food processing sector also suffers from certain constraints. The challenges for the food conservation, distribution and processing sectors are diverse and demanding, which need to be addressed to leverage the growth of agriculture and food processing sector. Following are the major challenges and strategies are suggested to overcome the challenges (Sakina, 2019).

6.1. Domestic Constraints in the Development of Food Processing Industry in India

Despite the significant economic potential of the FPI in India, it still faces massive domestic challenges, which include low level of processing, fragmented structure of the industry, consumer perception and lack of skilled manpower. Firstly, low level of processing means that at industrial level, less food is processed, as compared to household level. Most of the traditional food items like jams, jellies, pickles etc. are prepared at small manufacturing units or by households (Agarwal & Neogi, 2017).

Secondly, consumer perception with regard to processed food in India is not very optimistic and they consider that packaged food is not fresh, thus, leading to low consumption of processed food. Thirdly, food processing sector is still highly fragmented and unorganised. This led to the inefficacies in the sector and has failed to achieve the economies of scale (Agarwal & Neogi, 2017).

7.1. Challenges in Milk Quality

Demand for milk and milk products in India is growing very rapidly, owing to urbanization, customer convenience, and the change from loose to packaged milk products. At present, the dairy sector is rising at about 10-12 per cent annually. Based on population growth projections and an increase in urbanization over the next four decades, India is projected to need approximately 600 million tonnes of milk per year to meet the demand for milk and milk products. This means that India’s milk production needs to grow at around 3.2 per cent CAGR for the next 40 years (FICCI, 2020).

Main reason of poor quantity of milk is due to unhygienic and poor condition of animal farms and dairies. Even due to high demand in foreign country we cannot export such poor quality of milk product. Many times, Indian milk products get rejected in foreign nations due to unhygienic milking milk contains high number of microbial counts. Reasons behind the quality affected in India are due to poor health of animal, polluted water and food and Unclean surrounding in farm. So, it is necessary to consider all this challenges in improving milk production. Currently most of the milking animals are not screened on regular interval of time. So, there is lots of chances that some diseases can transmitted to human beings. Farmers use antibiotics and chemical drugs to increase the production of milk this will also affect the quality of milk. These issues can be avoided by regular screening of animals in animal husbandry and also maintaining history records of health, feed etc. Quality of feed should be checked regularly. There must be pollution control in the feed and water used in cattle farms (Bhagyalaxmi, 2020).

The major challenges to any developing society are poverty and economic deprivation of its ruralpopulation.Eradication of poverty, the focus of all developmental efforts has remained a very complicated and serious concern among developing countries. Poverty is abysmal rooted covering several interlocked aspects such as lack of asset, under employment, uncertain and relatively unproductive employment, low remuneration, economic vulnerability, illiteracy, social disadvantage etc.

The rural areas were found to be more prone to poverty, even if it exists in urban areas also. The rural poor are perpetuating poverty and are the victims of the “vicious cycle of poverty”. Fishing communities in the coastal belts all over the world are also not an exception to this. Poverty in fishing communities is very common and is characterized by high population density, poor living conditions, lack of proper education and poor access to education and health care. Due to poor attention paid by the state, the infrastructure support like roads, electricity, good drinking water, markets etc also are be poor. Though efforts for reducing fishing pressure is taken by Government, scope for alternative employment opportunities are less. Thus those sector that are in engaged inthe world’s most dangerous occupations, are considered on par with SC/ST communities as far as India is concerned. The loss of a boat, gear or an active fisherman in the family can be tragic and lead to total financial deprivation of the family. Hence poverty and vulnerability in fishing communities is widely known but poorly addressed issue. As in rural farming sector, dependence of fishing communities on private moneylenders continues in many areas, especially for meeting emergent requirements. For various reasons, credit to these sections of the population has not been institutionalized.

The emergence of microfinance as an alternative financial delivery mechanism was a response to the failure of past efforts by government and international agencies effectively to provide financial services to the poor. But while considering micro finance programmes for fisheries sector, there should be special considerations that are unique to fishing communities and need special consideration. Instead of random payment of loans to target sectors and populations, efforts were taken for setting up and building local institutions that cater for the poor. This resulted in the materialization of microfinance institutions (MFIs) that serve the rural poor. MFIs initially started providing microcredit but have now extended their services to savings, insurance etc.

Introduction

Protected cultivation or greenhouse cultivation is the most common technique to grow vegetable crops qualitatively and quantitatively, and has spread widely all over the world in recent decades. Greenhouse agriculture is also known as environmentally controlled planting. The technology involves the cultivation of vegetable crops in a regulated environment in which factors such as tem perature, soil, light, humidity, irrigation, fertilizers, etc. are controlled in order to achieve optimum production and ensure a steady supply even in off-season conditions. In India, the total area under protected cultivation or green house is currently approximately 25 000 ha whereas the protected vegetable area is approximately 2000 ha which has been challenged by land ownership limita tions, decreasing crop production, rapid urbanization, ever increasing popu lation and decreasing biodiversity. Food demand, especially vegetables, has increased growing of different crop varieties as protected crops, or greenhouse has opened up a new dimension to extra production within a limited crop area.
