Packaging machinery is integral to all packaging processes, from primary packaging to distribution packs. It encompasses various stages, including fabrication, cleaning, filling, sealing, combining, labeling, overwrapping, and palletizing.Food packaging refers to the methods, materials, and technologies used to package food items. It serves multiple purposes, such as prolonging the shelf life of products. However, food packaging is not a recent innovation, and its history is quite fascinating. Food packaging has existed in various forms throughout history. The Journal of Agricultural and Food Chemistry highlights that Napoleon played a major role in its development by offering a reward of 12,000 francs for anyone who could invent a method to preserve food for his army. This prize went unclaimed for 15 years until Nicholas Appert introduced the canning method. Appert’s process involved boiling food and sealing it in airtight glass containers, laying the foundation for modern canned food as we know it today.
EVOLUTION OF FOOD PACKAGING THROUGH AGES
The history of food packaging dates back centuries! The Chinese were pioneers in developing paper and wrapping materials, which were utilized for storing food. In ancient Egypt, advancements were made in glass-blowing and molding techniques, allowing glass to be shaped into various forms for food and water storage. Over time, innovations continued to evolve, with figures like Nicholas Appert leading the way. Appert's glass canning method eventually led to the creation of modern metal cans. In the 1880s, the food manufacturer Quaker Oats introduced cardboard cereal boxes as a packaging solution for their oats, further advancing food packaging technology.
Food packaging serves several vital functions beyond simply containing food. Here are Some Key Roles of Food Packaging:
• Preservation: Packaging prevents exposure to air and moisture, which can cause food to spoil quickly. Proper packaging extends the shelf life of food, benefiting manufacturers by reducing waste.

Introduction

The landscape of the Indian food industry has undergone a dramatic transformation in recent years. Rising disposable incomes, coupled with the rapid pace of urbanization, have fuelled a surge in demand for convenient and processed food options. Consumers, increasingly pressed for time, are turning towards ready-to-eat meals, packaged snacks, and a wider variety of processed food products. While this trend signifies a growing economy and changing lifestyles, it has also brought to light a critical concern: ensuring food safety and empowering consumers with clear and accessible information. In order to empower consumers to make educated food choices and build trust between brands and consumers, food label transparency is crucial. Transparent labelling is essential for improving public health because it gives precise and unambiguous information about ingredients, nutritional value, and possible allergies. This information helps prevent diseases linked to a certain lifestyle, such diabetes, heart disease, and obesity. Additionally, it guarantees that customers are not misled about the quality or provenance of their food, shielding them from dishonest business tactics. Transparency also promotes market justice by levelling the playing field, making product integrity apparent, and fostering creativity and brand loyalty. Transparent labelling promotes ethical and sustainable consumption while also facilitating international trade by adhering to regulatory norms in many countries.

Recognizing this need for a more transparent and consumer-centric food ecosystem, the Food Safety and Standards Authority of India (FSSAI) introduced the FSS Labelling and Display (L & D) Regulations in 2020 under the Food Safety and Standards Act, 2006 (FSS Act). This landmark legislation marked a significant shift in the way food is labelled and marketed in India. By establishing stricter regulations and mandating the inclusion of comprehensive information on food packaging, the FSSAI aimed to empower consumers to make informed choices while also promoting fair competition within the food industry. This comprehensive review delves into the intricacies of the FSS Labelling and Display Regulations 2020. It explores the key provisions of the regulations, analyzes their impact on various stakeholders, and examines the challenges and opportunities associated with their implementation. By providing an in-depth analysis, this chapter aims to shed light on the significance of these regulations in shaping a more responsible and transparent food industry landscape in India.

In the Modern era of globalisation, a wide variety of miscellaneous bakery products are available. It is hard to acknowledge all of them in this chapter due to the unlimited specialities of bakers across the world. The writing here in this chapter is limited to formulation & technology used for the production of buns, pizza base, chapatti, wafers, pretzels, crackers and muffins individually.

New Technique of Food Preservation

1. High Pressure Processing (HPP)

High Pressure Processing (HPP) is a method of food processing where food is subjected to elevated pressures (up to 87,000 pounds per square inch or approximately 6,000 atmospheres), with or without the addition of heat, to achieve microbial inactivation or to alter the food attributes in order to achieve consumer-desired qualities. Pressure inactivates most vegetative bacteria at pressures above 60,000 pounds per square inch. HPP retains food quality, maintains natural freshness, and extends microbiological shelf life. The process is also known as high hydrostatic pressure processing (HHP) and ultra high-pressure processing (UHP).

Introduction

Small and medium-sized industrial units, or small scale industrial (SSI) units, are generally referred to as SMEs, according to the Ministry of Micro, Small and Medium Enterprises. The MSMED Act of 2006, which was updated in 2020, serves as the foundation for the definition of SMEs in India.

• Micro manufacturing and services units: Up to Rs. 1 crore in investments and up to Rs. 5 crore in revenue.

• Small manufacturing and services units: Up to Rs. 10 crore in investments and up to Rs. 50 crore in revenue.

• Medium manufacturing and services units: Up to Rs. 50 crore in investments and up to Rs. 250 crore in revenue.

Small and Medium-sized enterprises (SMEs) constitute the backbone of the global economy. SMEs not only provide major contributions to national GDPs, but they also play an important role in job creation, innovation, and regional development. In India, SMEs account for about 30% of the country’s GDP and employ over 110 million people, making them an important part of the economic structure.(FICCI,2023).

The productivity of onion is closely associated with the availability of genetically pure, healthy and high-germinating seed. Farmers often face shortages of certified seed, rapid loss of seed viability and inconsistent quality within informal supply systems. Onion seed production is technically demanding because the crop is biennial, highly cross-pollinated and sensitive to environmental conditions. This chapter discusses floral biology, climatic requirements, selection of true-to-type bulbs, isolation, seed-to-seed and bulb-to-seed production methods, pollination, harvesting, processing, testing and storage. It emphasizes quality enhancement, organized seed systems and participation of trained growers and private agencies in expanding reliable seed availability and improving economic returns.

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..

Abstract

Seed technology deals with the various aspects of seed- right from production to make it readily and timely available to the end users. The advancement in seedtechnology was realizedlong back and itwas considered equally important to the development of new technology (varieties). Considering the importance of seed as well as variability among seed of different crop species or even in same crop species, the researchers initiated work and focused their direction of research accordingly which resultedinto worthy achievements. Brief overviews of the advancements made in seed technology are being discussed in this chapter. However, efforts are still on to get rid of problems of seed technology in order to strengthen the seed industry, which makes the highest contribution to rural development, probably among all industries.

Onion production is constrained by insect pests and diseases that damage seedlings, foliage, roots and bulbs and reduce both yield and market quality. Important pests include onion thrips, leaf miners, cutworms, armyworms and onion maggots. Major diseases include damping-off, basal rot, downy mildew, purple blotch, white rot and pink-root rot. Some insects also transmit damaging viral diseases. This chapter presents integrated cultural, biological, botanical, behavioural and chemical strategies for managing these threats. Crop rotation, sanitation, healthy planting material, proper spacing, resistant varieties, traps, barrier crops, beneficial microorganisms, natural enemies and need-based pesticides are discussed as components of sustainable crop protection and resistance management.

Abstract

Water scarce state Rajasthan is without efficient and effective management. Water, when at surface is cheaper and like free commodity to use. Most of it gets evaporated rapidly due to aridity. There is no water during summers and drought years. This is now critical time to rethink and review our planning and policies and make it ground water oriented instead of completely surface water based. Ground water management should be the thrust area and key issue. There is need to conserve andharvest each drop ofwater especially for recharge to ground water. Utilize the augmented ground water resources as crisis management during long dry spells. Also, enforcement of regulatory measures, creating awareness among masses and participatory approach ofmanagement are the key factors for ensuring sustainable availability of water resources.

This alternative pathway for glucose oxidation has enzymes in the cytosol through which glucose is degraded to carbon dioxide. It is also called a shunt because carbon atoms from glucose 6-phosphate take a long route before they proceed down the EMP or glycolytic pathway. This pathway is anabolic in nature as it produces many intermediates. In this pathway, two NADPH are generated from one glucose 6-phosphate molecule. No ATP is generated or consumed.
Overall, this pathway needs three glucose-6-phosphate molecules to complete all the reactions. Therefore, one cycle run produces 2 mol of fructose-6- phosphate, 1 mol of glyceraldehyde-3-phosphate, and 3 mol of carbon dioxide from 3 mol of glucose-6-phosphate with the reduction of 6 mol of NADP+ to NADPH.
Overall reactions of the HMP pathway are as follows:
3 Glucose-6-P + 6 NADP+→ 3 ribulose-5-P + 3 CO2 + 6 NADPH
3 Ribulose-5-P → 2 xylulose-5-P + Ribose-5-P
2 Xylulose-5-P + Ribose-5-P → 2 fructose-6-P + Glyceraldehyde-3-P

Introduction

The Indian dairy industry plays a vital role in the nation’s economic and social fabric, deeply connected to the livelihoods of millions of rural families. It is more than just a source of income; for many small-scale and marginalized farmers, it provides a lifeline, ensuring stability and sustenance in areas where opportunities are often scarce. At the same time, the industry faces the immense responsibility of balancing economic growth with ethical practices, environmental conservation, and the welfare of the communities it serves. In this complex environment, businesses operating within the dairy sector have the potential to make a meaningful difference, but only if they prioritize social responsibility alongside profitability. By embracing sustainable practices and fostering inclusivity, these enterprises can address critical challenges while contributing to a more equitable and resilient industry (Christie, 2020; Rotz et al., 2020; Clay et al., 2019).

For the dairy industry, social responsibility is not an abstract concept; it is a pressing need. Across India, small-scale farmers form the backbone of this sector, especially in rural regions where economic vulnerability is widespread. These farmers often face numerous challenges, including fluctuating milk prices, limited market access, and a lack of resources to improve productivity (Kamath et al., 2019; Sadashive et al., 2017). Businesses in the dairy sector can act as catalysts for change by creating fairer systems, empowering marginalized groups, and ensuring that ethical treatment of livestock becomes standard practice. Beyond its immediate economic impact, the industry has a profound role to play in addressing broader social issues, such as gender inequality and food security, while promoting sustainable development that benefits everyone involved (Jaiswal, 2018; Garai et al., 2019).

Fruits and vegetables are very important food commodities. India has become the largest producer of fruits and the second largest producer of vegetables. Though the production of fruits and vegetables make us believe in our strength for self-sufficiency, a significant qualitative and quantitative loss occur in the produce from harvest till consumption.  For self sufficiency and also for processing, export and to meet additional requirements, a lot of emphasis need to be given to reduce post harvest losses, besides increasing  production and productivity of horticultural produces. Processing plays an important role in  conservation and effective utilisation of these perishable commodities. However, only less than 2% of total production of fruits and vegetables are processed.  The new industrial policy has placed this sector in the list of high priority areas.

Note: With my personal experience, I have learnt many lessons during the course of my journey of life. The reader should ponder over it and prepare own food profile and menu for the benefit of maintaining good health. My paper does not provide any prescription but provides illustration of my experiences only, which may be of some use in knowledge and practice of food. The medical and health experts need to be consulted as appropriate.

Maturity at harvest is the most important determinant of storage life and final fruit quality. Maturity indices are determined for many fruit, vegetable and floral crops. Harvesting crops at proper maturity allows handlers to begin their work with the best possible quality produce. Produce harvested too early may lack flavour and may not ripen properly, while produce harvested too late may be fibrous or over ripe.
 
Almost all fruits reach their best eating quality when allowed to ripen on the tree or plant (exceptions e.g., pears, avocados, and bananas). In general, fruits become sweeter, more colourful, and softer as they mature. A few fruits are usually picked mature but unripe so that they withstand post harvest handling system when shipped long distances.  Most of  currently used maturity evaluation is based on a compromise between those methods that would ensure the best eating quality and those that provide flexibility in transportation and marketing.  Optimum harvesting stage depends upon type of fruit or vegetable and their final use. Such a division is usually based on their classification according to physiology, environmental conditions, ripening bahaviour and nutritional aspect. Some of the classifications, important for their harvesting and storage are briefed in  subsequent sections.

Abstract

Indian is rich biodiversity and availability of a variety plants of enhances the interest of scientist for the possible use of plant products as natural herbicides. The emphasis should be to collect the information about such plants from the concerned people who have traditional knowledge about the use of these herbs and then to study scientifically to arrive at conclusions. The study of compounds produced by a plant which inhibit or stimulate the germination and the development of other plants is important for understanding the mechanisms of the ecologicalinteraction. Therefore, there is continuing need to develop and release new phytotoxic chemicals that preserve the environment and enable a more efficient control of weeds, improving crop yield and quality. Ageratum conyzoides a herb traditionally used for treatment of many diseases, releases some potential allelochemicals and other chemicals to the environment which inhibit the germination and growth of neighboring plants. A complete study of its potential allelochemicals may be useful in biological control for sustainable agriculture.

Processing of fruits  and vegetables into various products which could be preserved for a long time and add to value of product using proper cost effective technology will be a viable tool for improving   economic status of  farmer as well as our country. Modern methods of fruit and vegetable preservation are  broadly classified as follows:

Bioinformatics is a field of science which studies biology, computer science, and information technology. The ultimate goal is to obtain useful information by data acquisition, analysis and interpretation of sequences data. In the current decade, a huge volume of sequence data is stored in the data bank due to global genome initiatives of many organisms. Management and understanding of the genome data cannot be possible without the bioinformatics tools. A large number of tools and softwares packages are available either commercial or freely online for the bioinformatics applications. The use of bioinformatics tools enhances the research capability for crop improvement through genome sequencing, database management, assembly, alignment, primer designing, markers development, genes prediction and annotation, gene expression, phylogenetics, protein structure identification, metabolic pathways analysis and many other applications.

Introduction Fruits and vegetables are basic foods for human physical health since they have a wide range of flavours and are linked to a higher quality of life. Horticultural crops are known to reduce the risk of a variety of chronic diseases. Recognizing the importance of fruits and vegetables in the human diet, demand for these horticulture food products has skyrocketed. The demand for fruits and vegetables has expanded significantly as a result of greater consumer awareness of dietary habits, the benefits of eating fruits and vegetables, and an increase in the global population. According to research by the Food and Agriculture Organization (FAO), horticulture product production for 2019 is expected to be 314.5 million tonnes, which is roughly 1% more than the global fruit and vegetable (F&V) production in 2017–2018. (FAOSTAT-FAO statistical database, 2019). Over 67 % of the world’s horticulture produce is produced in China, India, the United States, Turkey, Russia, Vietnam, and Mexico (Paggiola et al., 2016).
