Introduction In latest years, there has been an upsurge in customer situation over using artificial colorants in foods, especially on the subject of healthiness and safety issues (Amchova, Kotolova, & Ruda-Kucerova, 2015). Dietary colorants have been banned or regulated by the European Food Safety Authority (EFSA) and various other national authorities throughout the world because to their confirmed or suspected link to enhanced cancer progression or adverse reactions. For the same motives, various pigments are being investigated and are most effective provisionally authorized at this time. Consequently, the use of natural additives in food production is becoming increasingly popular among food companies (Schwartz, Joachim, & Giusti, 2007). Red C-PE is the most extensively used colour and has various application in food, cosmetics, and pharmaceutical industries; however, because they are rare in nature, they must be synthesized. Therefore, the food sector is expressing an increasing interest in the finding, application, and stabilizing of natural red colorants, which are currently in high demand. A growing number of commercial companies are turning to cyanobacteria for colour extraction, including Spirulina sp. for the extraction of Phycoerythrin, Haematococcus sp. for the extraction of astaxanthin pigments, and Dunaliella sp. for the extraction of beta-carotene pigments (Sharma et al., 2021).

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).

Introduction

Since 1990, there has been a lot of interest in functional foods and nutraceuticals, particularly because of their impact effects on human health and the prevention of certain diseases. Apart from growing good quality natural products, there are challenges in extracting, refining, analyzing active ingredients, and evaluating safety before an effective, reliable product is made [1,2]. Special attention needs to be focused on separation and purification mainly because 40-80% of the cost of production is assigned to separation and purification unit operations in making functional foods and nutraceuticals. There are also several carotenoids and polyphenol products that have been identified from various plants and a single plant could contain highly complex profiles of these compounds. These are labile to heat, air, and light, and they may exist at low concentrations in the plants. This makes the separation and detection of nutraceuticals a challenging task. The membrane techniques used for the separation of nutraceuticals from the natural products, as well as their applications and influencing factors are discussed in this chapter [3, 4].

Introduction Rice cultivation is a means of livelihood for a large number of people from the state of Assam, India (Saikia, 2019). It is related to the cultural aspects in rural Assam where people indulge themselves in traditional as well as modern ways of farming. Like any other north-eastern states in India, rice majorly dominates the Assamese cuisine. It is the primary source of diet in Assam. There are more than 100 varieties that are genetically modified breeds in which indigenous varieties contribute to 20 germplasm (https://www.rkbassam.in/). The different rice varieties of Assam have different culinary applications in both savoury and sweet cuisines. The intermediate and high amylose rice, parboiled or nonparboiled are consumed as staple for major meals while the low amylose rice is mostly consumed as snacks, breakfast cereals and desserts. The major constituent of rice is starch consisting of about 90% of the mass. Thus, the major compositional changes occurring in rice is due to starch. Starch is a polymer of glucose linked by glycosidic bond. It consists of amylose (linked by alpha 1- 4 linear chains) and amylopectin (alpha 1-4 & alpha 1-6 branched chains). On the basis of composition, rice is classified as high amylose (>25%), intermediate amylose (20 -25%), low amylose (7-20%) and waxy or glutinous (1–2%) types (Juliano, 1979).

Trade in fruit and vegetable products has been among the most dynamic areas of national as well as international agricultural trade, stimulated by rising incomes and growing consumer interest in product variety, freshness, convenience, and year-round availability. Advances in production, postharvest handling, processing, and logistical technologies—along with increased levels of international investments have played a facilitating role.

Abstract
Biotic stress in plants refers to the adverse impact of living organisms, such as pathogens, pests, and nematodes, on plant growth, development, and productivity. These biotic agents can infect, infest, or parasitize plants, triggering a range of physiological and biochemical responses that compromise plant health. Biotic stress can manifest in various forms, including fungal diseases, bacterial blights, viral infections, insect infestations, and nematode attacks, leading to reduced crop yields, lower quality produce, and significant economic losses. Understanding biotic stress is crucial for developing effective management strategies to protect plants and ensure food security, as it poses a significant threat to agricultural productivity and sustainability. To enhance the productivity of grain legumes, a critical food source for millions, mitigating biotic stress is essential. By adopting effective strategies to manage biotic stressors like diseases, pests, and nematodes, legume yields can be significantly increased.
This can be achieved through the development and deployment of resistant cultivars, integrated pest management (IPM) practices, cultural methods like crop rotation and sanitation, and biological control methods. Additionally, rhizobia and mycorrhizal inoculation can enhance plant defense and nutrient uptake, while precision agriculture techniques facilitate early detection and targeted management of biotic stress. By implementing these approaches, legume productivity can be boosted, ensuring food security, improving livelihoods, and meeting the growing demand for this vital crop.

The Government of India has accorded ‘high priority’ status to the food processing industry. The Ministry of Food Processing Industries (MOFPI) has been set up as a nodal agency for formulation and implementation of the policies and plans for the food processing industries.

With an overall objective of positioning India as the ‘Food Basket’ to the world, several initiatives have been undertaken with the objective of promoting investments, innovation and bringing best practices. This vision is in line with the ‘Make in India’ initiative of the Government (CII, 2019).

5.1. Policy Interventions (MOFPI, 2019)

5.1.1. Infrastructure Development

Fragmented, inadequate, and inefficient infrastructure along the supply chain has been identified as one of major factor inhibiting growth of food processing sector. As adequate investment for infrastructure has not been forthcoming from private sector, government will continue to assist, participate and incentivize creation of supply chain infrastructure for food processing sector.

Introduction
 
Diabetes shows a wide range of variation in prevalence around the world and it is expected to affect 300 million by the year 2025. In a prevention framework where banning policies and educational strategies lead the interventions, functional foods (FFs) with their specific health effects could, in the future, indicate a new mode of thinking about the relationships between food and health in everyday life. Functional ingredients, such as stevioside, cinnamon, bitter melon, garlic and onion, ginseng, Gymnema sylvestre and fenugreek, have been addressed for their specific actions towards different reactions involved in diabetes development. New strategies involving the use of FF should be validated through large scale population trials, considering validated surrogate end points to evaluate the effect of FF in prevention of chronic diseases such as type 2 diabetes mellitus.

Abstract
Understanding genetic diversity is essential for achieving genetic improvement and conservation of grain legumes. These crops serve as important pulses grown and consumed all over the world, especially in Africa, South East Asia and America. Legumes serve as a good source of carbohydrates, oil, fibre and proteins. Grain legumes are a major source of food and nutrition globally. However, it has not been possible to enhance gain legume production to the required level, primarily due to the narrow genetic base of most of the legume crops, coupled with changing climatic conditions. Most grain legumes are lacking in desired plant ideotypes and resistance sources for various biotic and abiotic stresses. The genetic diversity conserved in gene banks globally is a major resource for crop breeding programs, but it
is utilized only marginally. Therefore, in order to broaden the genetic base of grain legume crops and enhance the genetic gains made in improvement programs, conventional approaches and modern scientific tools should be integrated in a phased and carefully judged manner. The first phase should focus on the search for desired traits and the infusion of diversity into the cultivated gene pool through use of landraces and CWRs. The second phase should focus on the utilization of advanced selection tools, such as genomics, high-throughput precision phenotyping, and artificial intelligence, to exploit the hidden potential of the available genetic diversity; and the third phase should involve technologies such as mutational breeding, genome editing, and transgenic technologies to improve, modify any novel or alien traits that are not available in the entire crop gene pool. We presume that enrichment of the genetic diversity of cultivated grain legume gene pools, along with simultaneous improvements in their yield and plant type with the aid of advanced scientific tools, will enhance grain legume crop yields to the required level.

Milk is considered to be a perfect food which contains almost all the macroand micronutrients required for normal body growth. However, it is highly perishable in nature which poses problem during its storage. It gets spoiled within few hours after milking if not processed or cooled immediately. It can also be a source of several disease causing microbes as it is conducive for the growth of microorganisms.

1. INTRODUCTION

When the fruits and vegetables are ready for the intended purpose, these have to be harvested. What is meant by harvesting and how the produce is harvested, what are the harvesting methods, how these are packaged in what type of packages have been discussed in this chapter.

2. HARVESTING

Harvesting of produce at proper maturity is of paramount importance for maintaining quality during storage and marketing. When the produce is harvested immature or over-mature, it will affect the quality and storage life adversely. After the proper maturity stage has reached, the produce needs to be harvested for various markets. While harvesting, it must however, be kept in mind that all horticultural produce (with the exception of some dry fruits/nuts) is very delicate and mishandling at harvesting may lead to mechanical injury, compression injury that is irretrievable. The injury on fruits/vegetables enhances ethylene production, moisture loss and serves as an entry point for a wide range of pathogens, hence causing quick loss in quality and storability of produce. The injury caused to the produce during harvesting not only spoils the commodity but also makes it unfit for long-term storage or long-distance transportation. Proper training to the labour engaged in harvesting on what to harvest, and how to harvest and the use of proper harvesting tools can reduce considerably the postharvest losses.

Thermal heating methods are used from long time to decontaminate the food products from microorganism and therefore increase its shelf life and ultimately make the product safe for human consumption. But these methods diminish the sensory, physicochemical and nutritional properties of food (Barba et al., 2012). Also, the cost of generation of heat in manufacture of food product make the product costlier in thermal processing and also create environmental issue.

The last two decades have seen rapid growth and development in the industrial sector as well as urbanization has increased. Due to globalization and mass production of commodities, the situation in the modern world nothing like ever before. Food and dairy industries are also not left out from this massive expansion. Due to changing behavior and food consumption habits too, there has been a surge in the risk of foodborne illness. This has created a problem in terms of public health and sustainability

Sample Preparation

a) Plain products: Sample should be softened at room temperature. Since the melted fat tends to separate and rise to the surface, it is not advisable to soften the sample by heating on a water bath or oven or flame. Mix thoroughly by stirring with spoon or eggbeater or by pouring back and forth between beakers.

b) Ice-cream containing Fruits and Nuts: Fill one third part of the cup with ice cream sample. Melt the product at room temperature and mix until insoluble particles are finely divided (about 3-5 minutes for fruit pieces and upto 7 minutes for nut pieces). Otherwise, the product may be ground in a porcelain or glass pestle and mortar. Don’t let temperature exceed 25oC at any time during softening and mixing steps. If fat separation occurs, discard sample otherwise immediately pour mixture into wide jar and cap tightly. If allowed to stand, shake vigorously before taking sample for analysis.

1 Detection of Starch Introduction

Starch is widely available in several forms such as wheat flour, corn flour and commercially manufactured starch. It is extensively used by adulterators to raise the SNF content in the milk. When high amounts of starch are added to milk, it can cause diarrhea due to the indigestion of starch in colon. Apart from this, accumulation of starch in the body may prove very fatal for diabetic patients. In this method, starch in milk can be detected by using iodine solution. Iodine from the iodine solution gets absorbed on the starch molecule surface and resultant product of adsorption has deep blue colour.

Reagents

 • Potassium iodide

 • Iodine solution - 1% (Add 1 g of iodine and 5 g of potassium iodide in

distilled water and dilute to 100 ml)

India produces 146 million tons of vegetables (NHB report, 2011) and the total area under vegetable cultivation is around 8.5 million ha. Potato, tomato, onion, cabbage and brinjal account for around 60 per cent of the total vegetable production in terms of quantity. India’s annual fruit production is 75 million tons (NHB report, 2011) and the total area under fruit cultivation is around 6.3 million ha. The major Indian fruits are mango, banana, citrus fruits, apple, guava, papaya, pineapple, and grapes. Fresh fruits and vegetables play a vital role in Indian context and their marketing works as an influencing force in the economy. Though retailing of fresh fruit and vegetables is a low margin business, the market potential is very large in a country like India. This factor has attracted many corporates into this sector. Marketing of agricultural produce is different and more challenging than many industrial products because of the perishability, seasonality, and bulkiness. The very nature of small size of land holdings by the farmers, varied climatic conditions, production spread over wide geographical area, mainly in remote villages, diversified consumption patterns/habits of the Indian consumers and poor Supply Chain (SC) infrastructure makes marketing for fruits and vegetables more complicated. At the same time, Indian consumers demand fresh fruits and vegetables. Thus, Management plays a crucial role in marketing fruits and vegetables. Supply Chain efficiency not only helps in increased production and per capita consumption, but also contributes to economic development of the country. As a result, Supply Chain Management (SCM) throws both challenges and opportunities in marketing of fruits and vegetables. Efficient SCM in marketing, not only increases the profitability and efficiency of retailers, but also adds value to different stakeholders like cultivators (farmers), consolidators and consumers. Traditional Retail Model of fruit and vegetables is predominantly followed in unorganized retail sector. Players involved in this model are commission agents, auctioneers, wholesalers, traditional retailer of all type of formats family run ‘mom and pop’ stores, roadside shops, pavement shops and cart vendors apart from farmers and customers.

The term nanoscience defines controlling or modifying the shapes and sizes of the materials such that they lie in the range of a nanometre (1 nm = 10^-9 m) scale, typically 1-100 nm (Chavada et al., 2016). The application of these materials and systems by their suitable designing and production is what is known as nanotechnology. Richard Feynman, in 1959, first discussed the possibility of this advanced technology. However, the term was first used by Norio Taniguchi in 1974 (Chavada et al., 2016).

Juice and juice products represent a very important segment of the total processed fruit industry. Juice products are being marketed as refrigerated, shelf-stable, and frozen, in a variety of packages with increased emphasis on functionality, health attributes, new flavors or blends, and in some cases fortified with vitamins and minerals. High-quality juice operations are dependent upon a source of high- quality raw material.
Fruits provide an important source of energy for human beings. But the main drawback is that the availability of majority of fruits is seasonal and they are perishable. Hence, fruits need to be processed and preserved which extends their shelf life and also results in value-addition. India is a producer of many varieties of citrus fruits. Hence, it is sensible if processing industries are set up near the places where the fruits are grown. States like Maharashtra, Uttaranchal, Himachal Pradesh and the North-Eastern states are high producers of many fruit verities. Assam is a major producer of fruits such as pineapple, orange, lemon, mango etc. and it is grown in large quantities over here. Hence, fruit squash and cordial making activity in a small scale is highly recommended in these regions.

Milk, commonly referred to as the “ideal food,” is an essential source of nutrition for human consumption. Because of the growing human population and the rising demand for milk and milk products, there is more interest in and concern about the quality and safety of dairy products. Milk comprises chemical substances with various functions in the human body, such as carbohydrates, lipids, proteins, and trace elements (vitamins, minerals, etc.) (Guetouache et al., 2014).
