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.

4.1. Global Trade of Processed Fruits & Vegetables

4.1.1. Country Wise Trends of Export in Value-Added Fruits

Table 4.1 shows the processed fruits export of top 15 countries in the global market. The USA remained the largest exporter at global level with the exports valued at USD 15089573 thousand with a share of about 12 per cent. The Compound Annual Growth Rate (CAGR %) of the USA was noted 7.58 per cent. Spain is the second largest exporter of processed fruits and vegetables with the CAGR of 6.14 per cent and share of 8 per cent. Some other dominant exporting nations are namely, Mexico, Netherlands, China, and Chile, showing a CAGR nearly, 13 per cent, 11 per cent, 16 per cent and 9 per cent, respectively.

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.

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.

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.

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.

The History of Fish Keeping

Philip Henry Gosse (1810-1888) coined a term “Aquarium” which is now familiar to all of us, in his 1854 book The aquarium: An unveiling of the wonders of the deep sea.

The idea of keeping aquariums can be dated back to 2500 BC and has evolved into a complex hobby that exists today. Ancient Sumerians and Romans kept fish in containers as early as 2500 BC, similar to what we now know as fish tanks. These tanks were designed to keep fish alive long enough to prepare the specimen for food. It is also known that Romans and Babylonians kept ponds filled with fish for ornamental use (History of Fish Keeping as a Hobby).

As time progressed, the art of fish keeping became a “luxury for the rich” (DuHammel 1). Many people consider the Chinese as being the most important contributors to the hobby. “By 1136 AD Emperor Hiau-Tsung started to breed and keep these fish in a more controlled environment. Several new breeds of ornamental fish ornamental emerged.” (DuHammel 1). As more people became involved in the idea of fish keeping, having a goldfish was no longer an indicator of a person’s status. Many common people began to keep goldfish; the fish that they kept represented a good luck charm.

India is situated north of the equator between 8°4' and 37°6' north latitude and 68°7' and 97°25' east longitude, is the largest peninsular country in the world bordered by Arabian Sea in the west, Indian Ocean in the south and the Bay of Bengal in the east. India has a coastline of 8118 km and 0.5 million t sq. km continental shelf endowed with 2.02 million sq. km of Exclusive Economic Zone (EEZ). It has a catchable annual fisheries potential yield of 4.41 million occupying third rank in world marine fish production (Table 1). India’s territorial waters extend into the sea to a distance of 12 nautical miles from the coast baseline. The vital details on marine capture fisheries of India are given in table

1. INTRODUCTION

Since vedic times, importance of fermented milk and its products was known but the major attention to probiotic and its health related benefits was gained after Eli Metchnikoff’s publication entitled “The prolongation of life” in 1908. Due to the awareness of the role of nutrition in health and well-being, improved knowledge of diet-related diseases, consumer demand for probiotic and prebiotic products has been increased in recent years. The link between diet and health is flourishing the market for health-embracing population and opens an opportunity for Food and Dairy Industries meet the demand of this market. Probiotics, constituting live micro organisms, have been incorporated into drinks, food products, supplements (tablets, capsules and freeze–dried preparations) and prebiotic products. Milk, milk based products, fruits and vegetables are rich in functional food components such as minerals, vitamins, dietary fibers, and antioxidants (phytochemicals). Application of probiotic bacteria in such products further enhances the nutritional value of the food product. Probiotic juices produced from fruits and vegetables have also been in consideration in recent years. The food market is being getting captured by pro- and prebiotic food products day-by-day. Even the agro-industrial by-products such as whey, wheat straw, rice straw, sugarcane bagasse, etc. are being explored for the economical and cost effective production of prebiotic molecules. Thus, this chapter gives a comprehensive overview of pro- and prebiotics and their market potential.

Smoking is an ancient method of food preservation, which is also known as smoke curing, produces products with very high salt content (>10%) and low water activity (~0.85). Smoking is a process of treating fish by exposing it to smoke from smouldering wood or plant materials to introduce flavour, taste, and preservative ingredients into the fish. This process is usually characterised by an integrated combination of salting, drying, heating and smoking steps in a smoking chamber. The drying effects during smoking, together with the antioxidant and bacteriostatic effects of the smoke, allow smoked products to have extended shelf-life. Smoked seafood includes different varieties like, smoked finfish and smoked bivalves. Many of the smoked products are in the form of ready-to-eat.

Developments of modern food preservation technology, such as pasteurization, cooling/refrigeration, deep-freezing, and vacuum packaging, have eclipsed the preserving functions of many traditional methods including smoking. Nowadays, the main purpose of smoking has been shifted for sensory quality rather than for its preservative effect.

Depending upon how the smoke is delivered into the food and smoking temperature, four basic types of smoking can be defined: hot smoking, cold smoking, liquid smoking, and electrostatic smoking. Hot smoking is the traditional smoking method using both heat and smoke, which usually occurs at temperatures above 70 °C. For smoked fish and fishery products, a minimum thermal process of 30 min at or above 145 °F (62.8 °C) is required by FDA (2001). Therefore, after hot smoking, products are fully cooked and ready for consumption.

Nanotechnology-based preservation employs materials generally measuring between 1 and 100 nanometres. Their high surface-area-to-volume ratio, adjustable surface chemistry and responsiveness to external stimuli enable highly controlled interactions with foods and microorganisms. Nanomaterials may deliver antimicrobial compounds, antioxidants and other active substances in a controlled or targeted manner. Silver, zinc oxide and chitosan nanoparticles can be incorporated into coatings and films to reduce microbial contamination while maintaining sensory and nutritional quality. The chapter discusses nanoencapsulation, nanoemulsions, antimicrobial nanoparticles and nanosensors for detecting spoilage and monitoring shelf life. It also considers effectiveness, controlled release, food applications, safety assessment and potential regulatory concerns associated with nanotechnology.

Introduction

Since long time fermentation process is in use for the production of functional food products for human welfare. SSF is a cost effective industrially important method that could be used by food industries to improve the nutritional profile of natural substrates (Salar and Purewal, 2016; Postemsky et al., 2017). The process is being carried out by trained microbiologists in the presence of aseptic conditions using suitable starter culture on steam sterilized substrates. Steam sterilized substrates possess minimal amount of moisture so as to support the microbial growth during the fermentation period. Growth of microbial strains on specific substrates during the fermentation time results in formation of koji (antioxidant rich fermented product). Selection of substrates and starter microbial strains is an important step in the fermentation process which will determine the nutritional properties of fermented product. One of the major advantages of SSF at industrial level is its potential to be utilized on cereal grains, fruits, vegetables and even agricultural wastes (Salar et al., 2012; Postemsky and Curvetto, 2015; Bhanja et al., 2009). Most common substrates that are being used as solid platform for the growth of microbial strains are cereal grains.

Stone fruits belonging to family Rosaceae (sub family-Prunoideae) include several important fruit crops like peach, plum, apricot, cherries, nectarines etc. The World production of these stone fruits is approximately 45.49 million tones; out of which 39.61 million tones stone fruits are grown in Asia and India contributes 6.67 million tones of stone fruits annually. Among all the stone fruits Peach, Plum and Apricot production in world is 24.98, 12.05 and 4.11 million tones, respectively whereas India alone produces 287778, 261903 and 17862 metric tones of peach, plum and apricot, respectively (Table 1). These stone fruits are grown extensively in USA, Spain, France, Italy, Turkey, Morocco, Iran, Africa and Australia. In India, these are grown in J&K, Himachal Pradesh sub-mountainous tracts of Punjab, Uttarakhand, North East States and to the limited extent in the Nilgiris hills. Primarily, these stone fruits are used for table purposes or processed to prepare various types of value added products like jam, jelly, marmalades, preserves, baby foods, nectar, juices, squashes, concentrates, ready-to-serve beverages, wines and also processed into dried products.

Introduction

Fish and shellfish constitute an important component of global nutrition. Fish protein is an essential source of nutrients for many people, especially in developing countries. Health benefits of fish oil in preventing heart attack and other cardiovascular diseases are well appreciated. Mounting evidences suggest that the benefits of fish consumption are not limited to the well-known effects of fish oil alone. Fish is also a rich source of protein containing all essential amino acids, which is required for the body maintenance and muscular build-up. The protein content in most of the raw finfish meat is in the range of 17 to 22% (g per 100 g), while the cooked portions of some fish such as tuna may have as high as 30% protein. The amino acid score of fish protein compares well with that of whole egg protein, which is considered as a standard protein source. Fish is also rich in the non-protein amino acid - taurine, which has a unique role in neurotransmission. Apart from nutritional properties, fish proteins also possess a number of functional properties such as emulsifying, foaming, gel forming, water binding and fat binding properties, which are important in product formulations. These functional properties are mainly attributed to the major meaning myofibrillar proteins, actin and myosin.

During the processing of fish only the fillets are generally retained while the bulk of product (up to 66%) is discarded. About 30% of the total fish weight remains as waste in the form of skins and bones during preparation of fish fillets. This waste is an excellent raw material for the preparation of high value products including protein foods. The utilization of fish wastes help to eliminate harmful environmental aspects and improve quality in fish processing. Skin and bone are sources of high collagen content. The average quantity of waste generated during fish and shellfish processing operations (based on average annual marine landing data) is indicated in Table 1.

Food preservation is increasingly influenced by digital technologies associated with Industry 4.0. Ensuring food safety now requires not only microbial control but also authenticity, traceability, continuous quality monitoring and rapid decision-making. Artificial intelligence and machine learning can analyse complex datasets to predict shelf life, recognise spoilage patterns and assess risks arising during processing, storage and distribution. Internet of Things devices connect sensors across the cold chain, while blockchain supports transparent and secure traceability. Smart pH, temperature, humidity, optical and biosensors provide real-time information about product conditions. The chapter examines these technologies alongside automation while considering data quality, model validation, infrastructure, cost and industrial implementation challenges.
