Introduction

The international fish trade increases day by day reaching to a tune of USD 151 billion in 2020 (FAO, 2022). Many developing countries like India gain benefits from this trade as income through net foreign exchange reached to a level of 8.09 billion USD in 2019-20. Seafood supplied by developing countries contribute to 77% of fish consumption worldwide. The European Union (EU) is the single largest market for fish and fishery products to a tune of 91.74 billion USD in 2022 as a consequence of an increased per capita consumption among its Member States. Spain, Italy, Germany and the United Kingdom are the largest importer of fish and fishery products.

To protect consumer health and to protect the territory from the introduction of animal and plant diseases, the European Community (EC) has laid down joint conditions for imports of foodstuffs. The Directorate General for Health and Consumer Protection (DG SANCO) is responsible for food safety in the EU. The import rules for fishery products are framed of high standards with respect to hygiene, consumer safety and animal health status. It is important that importing countries and food business operators (FBOs) must understand the fundamental principles and requirements of the European Food Law to ensure efficient and smooth imports. The EU system relies on Government to Government assurances without any intervention of any private type certification or standards. The Competent Authority (CA) in the country of origin is responsible for giving the official guarantees to the EU regarding compliance and conformity to all requirements of its legislation. The Export Inspection Agency (EIA) is the Competent Authority in India for issuing the required official guarantees for export of fish and fishery products. The EIA maintains a complete list of all establishments under its control.

Summary

Animal tissue culture is a biological technique in which a piece of tissue is taken from an animal specimen and cells from this tissue are grown and maintained in an in vitro or artificial environment (Harrison, 1907). Aim of cell / tissue culture is actually to make cells as happy in the in vitro conditions, as they are in their natural environment. The objective of this chapter is to highlight those principles and procedures that have particular relevance to the use of cell culture in tissue engineering.

Abstract

Microencapsulation has found great applications in food business. However, the technology remains aloof from being fully exploited. Microcapsules offer food processors a way to shield sensitive food ingredients, mask or preserve flavours and aromas and conversion of volatile food components into easy-handled solid ingredients (like powders, capsules etc). A number of naturally occurring and synthetic polymeric materials have been identified so far that possess the entrapping property and are categorised as GRAS materials. Numerous techniques have been developed for using these entrapping materials to encapsulate the sensitive food ingredients. Controlled release of the food ingredients at proper place and right time could be therefore a key practicality that may be provided by microencapsulation. With strictly fine-tuned and stabilized release characteristic, this method adds worth to the merchandise. The areas of interest in this field include the development of alternative and inexpensive polymers that may be considered natural or mimic the properties of natural polymeric materials, like Gum Arabic, Gellan Gum, Gum Karaya, Gaur Gum and Gum Acacia. Limitations in many of the encapsulation techniques have occurred due to high value of raw materials and production. This review is effectively committed to the, properties of encapsulating agents along with the emphasis on different techniques used for encapsulation in the varied fields like food technology, pharmaceutical, commercial engineering and biotechnology.

Identification of enteric bacilli is of prime importance for controlling intestinal infections. This can be achieved by preventing contamination of food and water by a group of bacteria belonging to family – Enterobacteriaceae which are found in the intestinal tract of human beings and lower mammals. The microorganisms of this family are short, gram negative, non spore forming bacilli. Such common enteric bacteria are a) pathogens such as species of Salmonella and Shigella b) occasional pathogens like species of Proteus and Klebsiella and c) normal intestinal flora like species of Escherichia and Enterobactor.

Introduction

Nutrition is the study of how food and nutrients affect the body’s health and well-being. It encompasses all aspects of food, from the food production, processing, consumption and digestion by the body. A balanced diet included all the essential nutrients such as carbohydrates, protein, fat, vitamins and minerals for maintaining good health. The recommended daily intake of nutrients varies depending on the age, gender and physical activity of a person. The nutritional need also varies depending on the lifestyle and medical condition of a person. The nutrition facts are based on recommended daily intakes for various nutrients, which vary based on factors such as age, sex, and physical activity. These facts are given on food packaging or label, providing important information on the serving size, calories, macronutrients and micronutrients, and other ingredients.

Nutrition labels are mainly intended to guide the consumer in food selection. Nutrition information provided on labels must be true and should not mislead consumers. Nutrition labelling regulations are provided by countries to help manufacturers. The Codex guidelines on Nutrition Labelling provide guidance to member countries to develop or update their national regulations and to encourage harmonization of national standards with international standards. According to it, no food should be described or presented in false, misleading or deceptive way. Nutrition labelling cannot solve nutrition problems, instead it is one of the elements of nutrition policy.

11.1. Nutrition Facts

Nutrition Facts means the nutritional information required for most of the packaged food in many countries giving the energy value and nutrients contained in the food. Nutrition facts labels are required by regulation similar to other types of food labels. It provides detailed information on the nutrient content of the food such as the amount of fat, sugar, sodium and dietary fiber.

Endoscopy provides direct visualization of internal structures and is valuable for diagnosing mucosal and luminal disease. This chapter describes the principles, equipment and applications of endoscopy in veterinary patients. Gastrointestinal endoscopy allows examination of the esophagus, stomach and proximal small intestine and can facilitate tissue or fluid sampling and selected therapeutic procedures. Appropriate patient preparation and preliminary investigations, including history, physical examination, radiography and ultrasonography, are emphasized. Endoscopy is particularly useful for detecting mucosal lesions, foreign bodies, ulceration, inflammation and other gastrointestinal abnormalities. The chapter also introduces other endoscopic applications, including laparoscopic examination.

INTRODUCTION

Food is the basic need of human beings. It gets spoiled primarily due to microorganisms and enzymes. Energy is required for microbial growth and enzymatic reactions. At low temperature, the rate of biochemical reactions is slow resulting in prolonged storage life of food. It must have been observed long back that food could be stored for longer period without deterioration during the winter months. Since then this principle is being used to extend the storage life of foods. A sea change can be observed in development of low temperature preservation technology. It has travelled a long journey to reach this stage; however, a major break through took place in twentieth century. Low temperature technology is of two types; refrigeration and freezing. In refrigeration storage, water is in liquid phase and temperature is maintained above freezing point. In freezing technology, the food is stored below freezing point and water gets converted into ice. The former is short term preservation due to slow growth of microbes and lower enzymatic activity while the later is long time preservation due to inactivation of enzymes during blanching and inhibition of microbial activity due to unavailability of free water and much lower temperature. Low temperature preservation is widely accepted and is of commercially important in food supply chain.

Spectacular productivity gains have been achieved in wheat and rice in south and south-east Asia and also several other developing countries in Latin America and central Asia due to introduction of dwarfing genes in these two crops purely through conventional plant breeding approaches and these developments were christened as “Green Revolution” (Reynolds and Borlaug, 2006). The wheat breeding progrmme was being spearheaded by Norman Borlaug at CIMMYT (International Maize and Wheat Improvement Centre, Mexico) supported by Sanjay Rajaram and the rice breeding programme was under leadership of Gurdev Singh Khush at IRRI (International Rice Research Institute, Manila, Philippines) coinciding with these exciting developments during mid-sixties to mid-seventies. In recognition of these quantum jumps in yield of wheat and rice, Borlaug was awarded Nobel Peace Prize for Peace in 1970. Later on World Food Prize was instituted by joint efforts of Borlaug and his colleagues to honour Agricultural Scientists and others on pattern of Nobel Prize who had made significant contributions to sustainable food production and food and nutritional security globally. M. S. Swaminathan happened to be Director General, Indian Council of Agricultural Research when Green Revolution was taking roots in India and because of his enormous contributions to provide effective leadership to ensure that Green Revolution happened in India, M. S. Swaminathan is credited as “Father of Green Revolution in India” and he was the first recipient of World Food Prize in 1987 for spearheading the introduction of high-yielding wheat and rice varieties in India. G. S. Khush along with Henry Beachell received 1996 World Food Prize for achievements in enlarging and improving the global supply of rice during a time of exponential population growth and Sanjay Rajram was the 1914 World Food Prize recipient for his scientific research that led to huge increase in world wheat production.

Ecological engineering has recently emerged as a paradigm for considering pest management approaches that rely on the use of cultural techniques to manipulate farm habitat and to enhance biological control. In contrast to the intensive use of ecosystems, these days to enhance productivity can affect agro-ecosystems through soil and water depletion, biodiversity loss, challenging pest problems and disruption in flow of ecosystem services. Ecological engineering for pest management mainly focuses on increasing the abundance, diversity and function of natural enemies in horticultural crops habitats by providing refuges and alternate or supplementary food resources and also attracts different kinds of pollinators like honeybees.

In recent years several plant pathological laboratories have been using molecular techniques for identification of the fungal plant pathogens isolated from the diseased plants. These are specifically used for the confirmation of the pathogen identified based on their cultural and microscopic characteristics. With the help of fungal genomic studies, not only the genus but also the species of the pathogen is identified based on the genomic sequences available with NCBI, and provide the accurate identification of the fungal isolate. This identification method involves the following steps:a

Introduction
Sustainability in the digital age represents a transformative approach to addressing the critical challenges of economic growth, environmental stewardship, and social equity. For India’s vision of “Viksit Bharat” (Developed India) by 2047, integrating sustainable practices within the digital transformation framework is pivotal. This foundation has three primary pillars: technological innovation, inclusive development, and environmental responsibility.
Role of Technological Innovation: Digital technologies have emerged as essential drivers of change, reshaping traditional methods of governance, education, healthcare, and industrial processes. Initiatives such as Digital India have laid the groundwork for building a robust digital infrastructure, empowering millions of Indians, especially in rural areas, with access to essential services. Artificial intelligence (AI), the Internet of Things (IoT), and blockchain technology are transforming industries by enabling smarter decision-making, improving resource efficiency, and promoting transparency. For instance, AI-powered systems are being used to optimize energy grids, reduce waste in supply chains, and monitor environmental conditions. These advancements directly contribute to sustainability by minimizing resource consumption and mitigating environmental degradation. IoT-enabled smart cities enhance urban planning, improve waste management systems, and facilitate efficient energy use. India’s Smart Cities Mission exemplifies the integration of such technologies, targeting sustainable urbanization to accommodate the growing population without overburdening the environment.

6.1 Introduction

Stratigraphy is the branch of geology which deals with the study of rock layers (strata) and layering (stratification) in their chronological order. It is primarily used in the study of sedimentary and layered volcanic rocks in order to interpret geological history and age. The term historical geology is also used as a synonym of stratigraphy but in a wider sense, it deals with the whole sequence of events that make up the history of the earth from its origin and age relations of rock strata, evolution through its life form, and structures. The scope of stratigraphy is very wide; it involves description and classification of layered sedimentary rocks and also of igneous & metamorphic rocks. The study involves correlation between different areas like lithological characters, fossil content, geophysical and geochemical properties including absolute radiometric dating.

6.2 Principles of Stratigraphy

Stratigraphy is based on the following few principles:

6.2.1 Law of superposition

In a sequence of horizontal sedimentary rock layers, the younger layers are on the top and the older layers are at the bottom. To put it another way, in a normal sequence, each bed is younger than the bed beneath it. Geologists today use it as the basis for a bed-by-bed analysis of geological history in a given area. This is important to stratigraphic dating, which assumes that an object cannot be older than the materials of which it is composed. This law known as "Law of Superposition" was first proposed by the scientist Nicolas Steno in the 17th century.

Onion

Onion is very popular vegetable crop grown worldwide. Consumption is in the form of fresh, frozen, and dehydrated bulbs and green bunching onion. Origin of Allium cepa is still somewhat mystery. Vavilov (1951) suggested that the onion originated in the area of Pakistan. Others have suggested Pakistan, Iran & the mountain areas to the north (Jone& Mann, 1963). One fact is certain that the onion has been around in its present edible form for thousands of years. Onion recorded in tombs as early as 3200 B.C. It was mentioned as a food in the bible and in the Koran with reference thought to be around 1500 B.C. In addition to being a food considered by people, plant is having certain healing power. Some early drawing indicates that onions were used in spiritual offerings.

The history of plant growth regulation was knownfor many years before the time of Christ, when it was common practice in the Middle East to place a drop of olive oil on figs to promote development. The use of plant growth regulators (PGRs) to modify growth and flowering of pineapple began in 1930s. In eighteenth century when a carpenter was working in a greenhouse in the Azores Islandaccidently set fire to a pile of shavings. To the surprise of the grower who had thought his plants were ruined, they burst into flower instead of being damaged (Collins, 1960). In Hawaii, Rodriguez (1932) noticed in the pineapple fields that smoke from brush fires adjacent to the field caused premature flowering. The ingredients of smoke were subsequently found to be ethylene and acetylene, the unsaturated hydrocarbons. During the 1940’s, auxins were also shown to produce this effect,α-Naphthalene acetic acid (NAA), β-Naphthalene acetic acid (BNA), Fruitone and naphthaleneacetamide were the next forcing agent to become commercially used in pineapple. Since that time many works have been carried out with improving results like natural and synthetic compounds that alter function, shape and size of crop plants have been discovered. Today, specific PGRs are used to modify crop growth rate and growth pattern during the various stages of development from germination through harvest and post-harvest preservation. The use of regulating chemicals has become an important component of agro-technical procedures for most of the cultivated plants and especially for fruit plants.

Introduction
Panch Parivartan, which translates to “Five Transformations,” is an innovative framework that uses information technology (IT) to catalyze a profound and holistic transformation across multiple sectors of society, governance, and the economy. This framework aims to create a sustainable and inclusive model for development by leveraging IT to drive change in key areas, including governance, economic growth, social equity, education, and environmental sustainability. In India’s development, particularly in the drive towards a Viksit Bharat (Developed
India) by 2047, the Panch Parivartan framework outlines a roadmap where IT is the backbone for achieving transformative change. Through the strategic deployment of IT solutions, the framework seeks to address complex challenges, unlock new opportunities, and pave the way for a more equitable, efficient, and sustainable society.

1. INTRODUCTION

India is traditionally rich on agricultural knowledge. Presently modern farming is not sustainable in consonance with economics, ecology, equity, energy and socio–cultural dimensions. Indiscriminate use of chemical fertilizers, herbicides and pesticides to boost the yields have resulted in various environmental and health hazards along with socio–economic problems. The agricultural production has continued to increase, but the trend in productivity has started declining. The agricultural scientist’s and farming community whole heartedly aim at an alternative sustainable farming system which will be ecologically sound, economically viable and socially acceptable. The answer to the problem lies in refining our own traditional practices based on natural and organic farming methods offering several safe, feasible and cost effective solutions.

The term ‘Organic farming’, a system of farming is one which avoids synthetic fertilizers but rely upon crop rotation also using crop residues, animal manures, legumes, green manures, biofertilizers, organic wastes etc., to maintain the soil fertility and increase productivity. This system enables the nutrients leaching from perennial wood and vegetation and help to maintain organic matter and protect the soil from surface erosion. The world wide awareness for adopting organic farming has paved way for streamlining the production technology and certification by adopting the specified crop production practices. Organic farming practices in agriculture and animal husbandry are native to East Asian countries, like India and China. In China a strong national movement for animal waste recycling is in vogue, minimizing the use of inorganic fertilizers (Xu, 2000), while in our country specific crop production practices are developed in isolation and adopted locally.

The trend of use of chemicals and industrial inputs in intensive farming is increasing which resulted in soil health deterioration and increased environmental pollution which causes a great concern all over the world. Therefore an emphasis on the need to use the organics and other byproducts of agriculture and industry is emerging. Fortunately, the country is already rich with left over crop residues (185 million tonnes) but its use presently is limited. Apart from crop residues, there is an enormous quantity of cattle wastes out of which sixty per cent of the used for fuel purpose in rural areas.

Introduction

Climate change has been, and continues to be one of the important causes of low productivity from animal agriculture in tropical countries like India through crop failures, fodder scarcity and increased incidence of endemic animal diseases. It impacts animal agriculture and cause immediate danger for human societies as livelihoods and food production are being adversely affected. Farm ruminant animals contribute to food supply by converting low-value materials, inedible or unpalatable for human, into milk, meat, and eggs and directly contribute to nutritional security. Besides contributing over one-fourth to the agricultural GDP, it provides employment to 18 million people in principal or subsidiary status in India. Nearly two-thirds of farm households are associated with farm animal rearing and 80% of them are small landholders (≤2 ha). As a result of various socio-economic and market driven factors, during the last one decade, large scale transformation took place in both extensive and intensive animal agriculture with regards to type and breed of the animal. A lot of high yielding, low disease resistant and more vulnerable crossbreed animal population have been increased in present animal production systems inorder to meet the market demands. Climate changes could impact severely the economic viability and production of these intensive animal production systems through increased incidence of drought/?oods/cyclones/hailstorms etc. Drought and high ambient temperatures in particular, affects production of milk, meat and egg, reproduction, health of animals and condition of pastures. Changes in pasture and crop biomass availability and quality affect animal production through changes in daily or seasonal feed supplies. Heavy rains and associated ?oods would washout the fodder resources and animals. Recent incidences of severe hail storms are causing brutal injuries to the grazing animals. To mitigate the adverse affects of extreme weather events and cope with changing climate, much precised resilient technologies suitable to local conditions and resources are needed. Hence, one should be critical in recommending smart animal-agriculture technologies in view of much diversified and heterogeneous group of farmers and the resources accessible to them. This will help in sustainable productivity from animal-agriculture and profitability to the farmers even in the era of climate change.

Biotech crops or genetically modified (GM) crops or the transgenic crops are those crop plants into which certain genes have been introduced from unrelated sources beyond the boundary of sexual compatibility using techniques which bypass the normal sexual cycle. The transgenic production technology uses recombinant DNA technology where a recombinant DNA molecule is a vector into which the desired DNA fragment has been inserted to enable its cloning in an appropriate host. The recombinant DNA technology has opened up the flood gate of plant biotechnology to produce plants which are equipped with novel genes to produce products never heard of that a plant will do. Now transgenics in several crops have been commercialized globally. The importance and potential of GM crops can be realized from the fact that acreage under such crops at global level has reached to 189.8 million ha covering 24 countries in 2017. One can have a feel of this huge acreage under commercialized GM crops globally if it is compared with about total cultivated area of 143 million ha in India.

Over the last 30 years field of agricultural biotechnology has expanded rapidly due to greater understanding of DNA as the chemical double helix code from which genes are made. Genetic engineering is one of the modern biotechnology tools that are based on recombinant DNA technology. The term genetic engineering, often interchanged with terms such as gene technology, genetic modification, or gene manipulation, is used to describe the process by which the genetic makeup of an organism can be altered using “recombinant DNA technology.” This involves the use of laboratory tools and specific enzymes to cut out, insert, and alter pieces of DNA that contain one or more genes of interest. The ability to manipulate individual genes and to transfer genes between species that would not readily cross is what distinguishes genetic engineering from traditional plant breeding and opens up a huge opportunity to create crop plants equipped with desirable genes from the sources which cannot be sexually crossed. With conventional plant breeding, there is little or no guarantee of obtaining any particular gene combination from the millions of crosses generated. Undesirable genes can be transferred along with desirable genes or while one desirable gene is gained, another is lost because the genes of both parents are mixed together and re-assorted more or less randomly in the offspring. These are the major limitations of conventional crop breeding.
