Introduction

Spectacular accomplishment in every sector has enabled India to be amongtop achieving nations. However, every section of the society is not benefited by these achievements and problem of malnutrition still remains unresolved. Malnutrition is a common problem faced by underdeveloped and developing countries suchas Philippines, Nepal, Sudan,Tanzaniaand Indiasincelongback. Malnutrition includes undernutrition(wasting,stunting,underweight),inadequate vitamins or minerals as well as overweight, obesity and resulting diet-related non communicable diseases(NCDs). As per the latest report of World Health Organization, 52 million children under 5 years of ageare wasted, 17 million are severely wasted and 155 million are stunted, while 41 million are overweight or obese (WHO, 2018). More than 50% women of marriage age are suffering from anemia. If women are malnourished at the time of pregnancyand delivery, the babybornface theproblems such asphysical retardation,sensitive tocommon infections, reduced cognitive abilities, reducedmental development, etc. As per the World Health Organization (WHO) guidelines, starting from the date of conceiving a child, the first 1000 days are a critical window from nutrition point ofview.Unfortunately, inseveral regions of developingcountries includingIndia, neither the mother nor the babyis provided with the right quantity and qualityof food during this window period. Therefore, it is important for the policymakers to identifymalnutrition at an earlystage for timelyplanningand implementation of various intervention strategies at the community, village, and district level. NitiAyog, Government of India (GoI) (previously known as Planning Commission), in an effort to eliminate malnutrition,regularlyplans several short and longtermnutritionalprogrammesand policies.In thischapter,we willdiscuss some of these policies launched since independence and their impact in combatingmalnutrition.

Before beginning the actual work on the establishment of a Fruit and Vegetable Processing Industry the following points should be considered:

Availability and possibilities of obtaining Funds: Investment of own money or obtaining loans from banks etc.

The scale of industry (Large, Small, Cottage or Home): Has to be decided based on availability of raw material, funds availability, land, labour and other resources.

The location: The processing unit should be located near to the actual production site of raw material so that the transportation costs of high bulk raw materials is reduced. There is no fun or justification of establishing apple processing industry in Lucknow or Bangalore and mango processing industry in Shimla as the related raw materials would have to be transported through long distances.

Site: Site selected in the location should be sunny area free from dampness and sufficient space for waste disposal should be ensured.

An ice cream plant is a highly interconnected operation in which quality, food safety, productivity, maintenance, cost, cold-chain performance, and business results influence one another. This chapter presents plant audits as management tools rather than simple compliance exercises. It provides a structured monthly audit system covering raw materials, production, quality assurance, hygiene, maintenance, productivity, cost control, warehouse operations, cold chain, documentation, and KPI performance. Department-wise scoring enables management to compare performance, identify weaknesses, prioritize corrective actions, and track improvement. The chapter also discusses common audit mistakes and best practices. A disciplined audit system strengthens accountability, reduces losses, improves operational control, and supports continuous improvement.

Introduction

Vast proportions of the population of the world are dependent on plants as their principal source of food either directly or indirectly. Recent decades have also seen increased numbers of people turning to alternative medical therapy based upon traditional folk medicine or food as a form of medicine. These alternative therapies emphasise the importance of a ‘good diet’ in maintaining and restoring health. Under these circumstances, vast majority of population may see diet therapy, dietary supplements and non-invasive alternative therapies as a safer, less technological and more natural way of maintaining health and treating and preventing individuals from illness. These alternatives may be seen as empowering the consumer and shifting the locus of control away from the medical establishment. This chapter covers many crucial topics to understand the chemistry and bioactivity of the active compounds of plant origin. It also aims to cover the latest research on the bioactive compounds.

Abstract

The establishment of All-India Coordinated Wheat Improvement Project in 1965 coincided with the introduction of high yielding semi-dwarf wheat varieties. Since then India has made very impressive progress in increasing wheat production over the past three and half decades. India now ranks as the second largest wheat-producing nation in the world. In fact from a state of “Ship to mouth” in 30 years or so India has become a nation of surpluses. The significant contribution made by the project in helping the increased wheat production cannot be ignored. Through coordinated research and development, nearly 200 wheat varieties have been developed during the last 35 years in India. However, only a small number of them produced without backing of specific quality breeding programs excel in quality traits also. The increasing demand of baked and pasta products in the country along with economic liberalization and global trade have offered opportunities for better utilization of the surplus wheat. Thus, in the current decade and beyond, wheat quality needs uppermost attention to meet the trade requirements for domestic and export purposes. Therefore, there is a need to reorient the wheat improvement programs in the country.

Introduction
Plant breeding and genetics are at the forefront of agricultural innovation, playing a crucial role in enhancing crop traits to meet the ever-growing demands for food, fiber, and fuel. This chapter delves into the scientific principles, methods, and modern advancements in plant breeding and genetics, providing a comprehensive understanding of how these disciplines contribute to global food security and environmental sustainability. The chapter begins by exploring the fundamental principles of plant breeding, including heredity, genetic variation, selection, and hybridization. These concepts form the foundation for developing new plant varieties that exhibit desirable traits such as improved yield, disease resistance, and environmental adaptability. The importance of genetic variation is emphasized as a key driver of plant improvement, with discussions on the sources of genetic variation, the role of germplasm resources, and the impact of genetic diversity on plant adaptation. As the chapter progresses, various breeding techniques and strategies are examined, including mass selection, pedigree breeding, backcrossing, and markerassisted breeding. These methods are crucial for developing new plant varieties that can withstand the challenges posed by climate change, pests, and diseases. The chapter also addresses the role of genomics in plant breeding, highlighting the significance of genomic selection, gene editing, and bioinformatics in accelerating the breeding process and enhancing crop traits. The chapter further explores the controversial topic of genetically modified organisms (GMOs), discussing the principles of genetic engineering, the rise of genetically modified crops, and the associated controversies and concerns. The importance of GMOs in addressing global food security and environmental challenges is also discussed, providing a balanced perspective on their potential benefits and risks. The chapter concludes by emphasizing the critical role of plant breeding and genetics in ensuring food security and combating global warming. By developing climate-resilient crop varieties, improving water efficiency, and enhancing disease and pest resistance, plant breeding and genetics can contribute to sustainable agricultural practices that reduce greenhouse gas emissions and conserve natural resources

Introduction
Plant protection is a critical component of modern agriculture, aimed at safeguarding crops from diseases, pests, and weeds that can significantly impact yield and quality. Chapter 10 explores the science of plant protection, focusing on the various disciplines that contribute to maintaining healthy crops and ensuring food security. The chapter begins with an overview of plant pathology, the study of plant diseases caused by pathogens such as fungi, bacteria, viruses, and nematodes. Key principles of plant pathology are discussed, including the nature of plant diseases, their modes of transmission, and the factors that influence disease development. This section also highlights the importance of accurate disease diagnosis, which is essential for implementing effective prevention and control measures. Entomology, the study of insects and their interactions with plants, is another crucial aspect of plant protection covered in this chapter. The principles of entomology are examined, with a focus on the identification and management of insect pests that threaten crops. Various pest management strategies, including biological, chemical, and cultural methods, are explored, emphasizing the need for a holistic approach to pest control. Integrated Pest Management (IPM) is a central theme in plant protection, combining multiple strategies to manage pests in an environmentally sustainable manner. The chapter discusses the advantages of IPM, such as reduced reliance on chemical pesticides and minimized environmental impact, as well as the challenges associated with its implementation. Integrated Disease and Pest Management (IDPM) is also introduced, which integrates plant pathology and entomology principles to develop comprehensive management strategies that address both diseases and pests. The chapter further explores the role of pesticides in plant protection, including their benefits and potential risks. Safety measures for pesticide use are emphasized to protect both human health and the environment. Integrated Weed Management (IWM) is also discussed as an essential component of plant protection, with strategies for managing weeds that compete with crops for resources. The importance of plant protection sciences in food security is highlighted, particularly in the context of pest management, disease control, and weed management. These disciplines contribute to sustainable agriculture by enhancing crop yield and quality while promoting environmental sustainability.

Introduction

Tissue culture refers to the technique of growing cells, tissues, or organs under controlled, artificial conditions. This allows propagation of tissues from a small sample of cells/tissues under sterile conditions. Plant tissue culture is widely used for various purposes, including the production of disease-free plants, rapid multiplication of plants with desirable traits, genetic modification, conservation of rare or endangered species, etc. Tissue culture is a valuable technique because it enables consistent and large-scale production of plants, ensures genetic uniformity, and allows manipulation of plant biology at cellular level. In this chapter, we will discuss about the major types of tissue culture techniques and their advantages, disadvantages, as well as applications in brief.

Different Types of Tissue Culture

Callus culture involves induction and growing of unorganized, undifferentiated cell masses from an explant on a nutrient/culture medium. The part of plant used to induce callus is called explant which can be tissue, organ or part of a plant.

Organ culture is used to maintain or grow an entire organ or a part of organ in vitro. It preserves the structure and function of the organ for studies or transplantation.

Embryo culture involves isolating and growing embryos from seeds or ovules in a nutrient medium. It is used to bypass seed dormancy or rescue embryos from hybrid crosses that may not develop naturally.

Cell suspension culture involves growing dispersed cells or small cell clusters in a liquid medium under continuous shaking. This is used for large-scale production of cells, secondary metabolites, and studying cell biology..

Pineapples are commonly propagated through vegetative means, as the crop sets very few or no seeds and seeds possess slow germination process and low survival rate of seedlings under natural conditions. Vegetative parts such as stem suckers, peduncle slips, and fruit crowns are commonly utilized for vegetative multiplication of pineapple.

Selection of planting materials: Slips or hapa suckers are commonly preferred for commercial multiplication because they may produce fruit within 14-16 months after planting. Crowns are not commonly used as they may take up to 24 months after planting to harvest. Ground suckers (ratoon) and side suckers (side shoots) produce fruit 12-14 months and 18-20 months after flowering, respectively.(Pineapple Technical Group, 1999).

The fresh suckers should not be used for planting. Pineapple suckers should be stored for a few months to allow them to dry before planting, as they may begin to decay if planted in moist soil. Suckers are graded according to vigour and size, such as small, medium, and large. Planting the same graded suckers in the same plot helps to avoid uneven growth of the plant, uneven flowering times, and harvesting times. Additionally, using uniform planting material makes cultural practices easier, increases labour efficiency and other inputs, ultimately reducing the cost of cultivation.

Chadha et al. (1974) observed the superiority of slips and suckers as planting materials compared to crowns. In both slips and suckers, larger planting materials resulted in more vigorous plants. Medium-sized slips or suckers led to more flowering, while larger grade material resulted in a more staggered f lowering period. Smaller slips or suckers yielded fruit earlier. Slips produced better quality fruits, and the yields were comparable to the highest yield obtained with the largest suckers.

Plasma Activated Water (PAW) is an emerging technology that combines the reactive properties of plasma with water to create an effective medium for food preservation and decontamination. This chapter explains the principles of PAW generation and examines different generation systems, including atmospheric pressure plasma jets, corona discharge and dielectric barrier discharge. It explores applications of PAW in reducing post-harvest losses, extending the shelf life of highly perishable foods, supporting edible-coating formation, controlling undesirable enzyme activity and improving food safety. The chapter emphasizes the potential of PAW as a sustainable processing approach while discussing treatment conditions, food-matrix interactions, technological limitations and opportunities for future development in food preservation.

2.1. Introduction

The word ‘plastic’ is derived from the Greek word ‘plastikos’, which means easily shaped or molded. Plastics is defined as a random set of materials based on synthetic or modified natural polymers which can be formed by thermal and pressure treatment. It comprises of wide range of macromolecular organic compounds obtained either from alteration of natural macromolecules or polymerization of molecules of lower molecular weight.

Plum belongs to the genus Prunus under family Rosaceae. The European plum are Prunus domestica and Japanese plums are Prunus salicina and hybrids. Mature plum fruit may have a dusty-white coating that gives them a glaucous appearance and is easily rubbed off. This is an epicuticular wax coating and is known as “wax bloom”. Dried plum fruits are called dried plums or prunes, although prunes are a distinct type of plum, and may have pre-dated the fruits now commonly known as plums. The major plum producing states are Himachal Pradesh, Jammu & Kashmir, Mizoram, Punjab, Tamil Nadu (Ooty) and Uttarakhand.

Cultivars/Varieties: Damson plum, Greengage plum, Mirabelle plum, Victoria plum, Satsuma plum and Yellow plum.

Uses

Plums are mainly used consumed as fresh fruits. They are also used widely for making jam, jelly chutney and squash. Certain varieties of European plum are specially suited for drying to produce prunes. Prunes are firm fleshed fruits of P. domestica cultivars having sugar content which can be dried whole without fermentation around the pit, to make a firm tasteful product that can be stored for long period.

A TTO fills the important intermediary position of linking research institution with industry so that innovations and new ideas can reach market. To be able to facilitate that effectively, the institutions must have well-defined R&D policies that include Sponsored R&D, Collaborative R&D, and Grant-in-Aid R&D. These ensure that the research remains properly managed, regulatory compliance assured and aligned with institutional priorities. This chapter has discussed about key policies that can help in successful operation of TTO while aligning institution’s mission and interests Various core policies that help in successful technology transfer include:
• Intellectual property policy
• Technology transfer policy
• Revenue sharing policy
• Startup/Spinout/Venture creation policy
• Conflict of interest/Conflict of commitment policy
Each policy has specific objectives. These policies collectively ensure a clear and consistent framework for technology commercialization.
11.1 Intellectual property policy
An IP policy is a formal document that provides guidelines for managing IP by an organisation. A strong IP policy build trust by ensuring efficiency and transparency. Other benefits of IP policy includes creation of environment to encourage innovation and commercialisation of IP. It also lays foundation to set out the rules for public-private partnerships while addressing issues among various stakeholders and ensures compliance. IP Policy is not law, but a proposed course of action.

To look into the nutritional security around the globe, FAO and WHO, have undertaken the analysis of policies. They have covered many issues which include; World Summit on Food Security, pillars of food security and availability, access, utilization, stability, effects of food insecurity, stunting and chronic nutritional deficiencies, depression, anxiety and sleep disorders. There are many challenges to achieve food security. These include global water crisis, land degradation, climate change, agricultural diseases, food versus fuel, politics, food sovereignty, food wastes, risks to food security, population growth, fossil fuel dependence, homogeneity in the global food supply, price setting, land use change, global catastrophic risks, agricultural subsidies and role towards children.

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).

Its juice is sweet with pleasant aroma and is refreshing. The fruit is widely used for Ayurvedic and Unani medicines. Some of the commercial products of pomegranates are juice, squash, syrup, jelly. Anardana is obtained by drying the seed along with pulp and sun. The rind is used as a valuable tanning material. The flowers yield a red dye.

1.1 Introduction

Pomegranate (Punica granatum L.) is a well-known table fruit of tropical and subtropical regions of the world. The Romans received it from Carthage, hence the name of the genus Punica. Some botanists place it in the family Lythraceae, of the peculiar type of fruit, called as balausta, most authorities make it the only genus in the family Punicaceae. It belongs to genera Punica and family Punicaceae (Chatterjee & Randhawa, 1952; Joshi, 1956). It is a small tree, measuring less than 4 m when cultivated, although it can reach 7 m in the wild. Recent research findings corroborate traditional use of pomegranate as a medical remedy as all parts of this plant have several bioactive metabolites (Holland et al. 2009). Consequently, its demand has increased tremendously not only in the western world but also in other parts of the globe.

1. INTRODUCTION

India is a vast country having a geographical area of 328 million hectares with 15 distinct agro-climatic zones. Fruits and vegetables are one of the most important and fast growing sub-sectors as they form an indispensable part of healthy diet. It holds a unique position for growing a wide range of vegetables in its diverse agro-climatic conditions. World production of vegetables amounts to 486 million tons, while that of fruits is 392 million tons. India produces 159.5m MT tons of vegetables from an area of 9.07 million hectare annually (NHB, 2013). Productivity of vegetables in India presently is 16.7 tons per hectare. India produces 36 % green peas and 10% onion of world’s production. Onion, potatoes and green vegetables like okra, bitter gourd and green chillies also have good export potential. Being rich in vitamins, minerals, dietary fibre and natural antioxidants most vegetables are classified as the protective foods. However, owing to the presence of high moisture content and mostly being non acidic, the vegetables are highly perishable and needs to be handled properly and immediately after harvest. Processing of vegetables into different value added products is one of the most effective alternatives to reduce post harvest losses.

Vegetables are highly beneficial for the maintenance of health and disease prevention. An intake of about 280 grams of vegetables per day per person has been considered essential. Vegetable unlike cereals deteriorated quickly when stored for long periods because of the relatively high moisture contents. Huge amounts of losses take place between harvesting and consumption. Various causes are attributed to the deterioration process and it becomes essential to adopt integrated, low cost system of post harvest technology right from the pre-harvest stage.

Flowers are highly perishable unlike other horticultural or agricultural crops. Owing to poor keeping quality the post harvest losses in floriculture are significantly higher than any other sector. Although there has been significant increase in the area, production and productivity of flower crops in the last two decades, there is an urgent need to minimize the huge post harvest losses in terms of the value of the produce which are estimated to be 30-40 per cent of farm value. The post harvest behavior of flowers is an outcome of the physiological processes, occurring in leave, stem, flower bud, leafless peduncle or scape connecting bud to the stem. Some of these processes may act independently to affect the senescence and vase life of cut flowers but most of them are inter-related. The nature and extent of post harvest damage is typical for each crop or cultivar. The post harvest losses become important especially when dealing with the export of fresh flowers to distant and foreign market. Therefore, patient, soft and expert handling of flowers is of utmost importance after harvest.

Fruits and vegetables are living tissues subject to continuous change after harvest. Some changes are desirable from consumer point of view but most are not. Post-harvest changes in fresh fruit cannot be stopped, but these can be slowed down within certain limits to enhance the shelf life of fruits. The post-harvest handling plays an important role in extending the storage and marketable life of horticultural perishables.

Post Harvest Treat ment of Fruits and Vegetables Washing

It is useful in removing surface adhering material water. Mechanically, it is also accomplished by passing the fruits/vegetables through machine arranged with water tank equipped with rotating brush. In some produce washing improves appeal by facilitating removal of sap as case in mango, papaya, jackfruit, kronda, dirt in case of carrot, reddish, turnip, sugar beet, sweet potato, etc. and for removal of debris in case of banana. The water use for the purpose should be cleaned otherwise fungal and bacterial levels may build up. Disinfected treatment using ultraviolet light, ozone, chlorine (100 ppm), calcium hydroxide, etc. help to clean water for washing purpose.
