India is emerging as a food power in the international trade of foods. The immense un-tapped potential in the food processing sector in India has to be still exploited. It has been termed as ‘sun rise industry’ for improving agricultural productivity and enhancing food availability. The terms food quality management and food safety have assumed large dimensions today. In the international trade of foods, specifications have been laid down on the levels of harmful substances (chemical or biological origin), protocols have been documented on their detection and quantification in foods. We have to meet these international standards to export processed food and earn foreign exchange. The future of Indian food processing sector is bright provided it improves the quality of its products as per international standards.

The proximate system of analysis consists of the analytical determinations of water (moisture), ash, crude fat (ether extract), crude protein and crude fibre. Nitrogen-free extract (NFE), more or less representing sugars and starches, is calculated by difference rather than measured by analysis.

Water

1. Water constitutes about 70 percent of an adult’s body weight and water (moisture) is the predominant constituent in many foods.
2. All foods contain varying amounts of water in the range of 20 to 90%.
3. The hypothalamus is a brain center that controls activities such as maintenance of water balance, regulation of body temperature, and control of appetite.
4. Moisture content of some foods

Food is defined as any substance, whether processed, semi processed or raw, that is intended for human consumption as well as the inedible parts associated with food that are not intended to be consumed by humans. Food waste is defined as any food and inedible parts of food, removed from the food supply chain that can be recovered or disposed, whereas, food loss is defined as food that unintentionally undergoes deterioration in quality or quantity as a result of food spills, spoils, bruising, wilting or other damages alike owing to infrastructure limitations at the production, storage, processing and distribution stages of food lifecycle. Global food waste management is an issue of concern that requires attention from various stakeholders having diverse expertise. According to statistics, about one third of the food produced for human consumption is either lost or wasted. Globally, the cost of food waste accounts for USD 2.6 trillion, of that USD 1trillion is incurred from greenhouse gas (GHG) emissions, water scarcity, biodiversity loss, increased conflicts and loss of livelihood owing to issues like soil erosion, nutrient loss, reduced yields, wind erosion and pesticide exposure.

Introduction

Food adulteration compromises quality of foods and causes human health hazards is a menace mankind had been facing since ages. Spice adulteration scandals in the year 2004, Horse gate scandal in Europe during 2013 are famous examples of food fraud. Various forms of food adulteration and cheating such as substitution of cheaper food components in place of original product, addition of non-permitted substances, and false claims by misbranding or mislabeling are prevalent from time immemorial (Spink et al 2019).

Formulation of meat and sea food products requires various ingredients which are commonly known as food additives. Food additives are those non-meat ingredients which are used to enhance colour, flavour, aroma and texture of the meat and sea food products. These food products can fulfil the demand of modern consumers. As per the definition of Food and Drug Administration (FDA) food additives are those substance which are used to provide a technical effect in foods. The use of food additives has become more prominent in recent years, due to the increased production of prepared, processed, and convenience foods. Additives are used for flavour and appeal, food preparation and processing, freshness, and safety. These additives can be classified as curing ingredients, extenders and binders, flavour enhancers and other additives. For the formulation of different products both raw materials and ingredients should be of food grade and sound hygienic strength. In the starting of this chapter we will discuss about ingredients used then the specific formulations will be discussed for better understanding of meat and sea food processing.

Curing Ingredients

Curing agents such as salt, phosphate, sugars, nitrite and nitrate, sodium ascorbate and erythorbate etc. have traditionally been used in various meat formulations from long back. The details of these ingredients have already been discussed in chapter-8 of this book. So we will try to discuss other ingredients which are relevant for meat and sea food products other than these ingredients. Cure accelerators such as ascorbates and erythorbates are used to speed the curing process. They also stabilize the colour of the final product. The examples are ascorbic acid, erythorbic acid, sodium erythorbate, citric acid, sodium citrate, sodium acid pyrophosphate, glucono delta lactone (GDL) etc. Glucono-delta-lactone (GDL) acts as a curing accelerator in meat and meat products. It is permissible up to 1% in sausages and up to this level it lowers the pH about 0.5 thus inhibits the growth of spoilage micro-organisms. GDL also facilitate the cured colour development.

Introduction

In developing countries, ruminants thrive mainly on poor quality feeds and pastures, whose nutritive value is poor. They are having a low content of nitrogen, energy, minerals and vitamins and high content of lignin and silica, which limit their efficient utilization by ruminants. Therefore, these poor quality feeds and fodder needs to be upgraded in terms of their nutritive value using various treatments like physical, chemical, physico chemical and biological methods to improve intake and utilization of nutrients from poor quality roughages. However, supplementation of critical nutrients like energy, protein, minerals, vitamins also improved the productivity and health of the ruminants (Dass et al., 2011). Availability of oil cakes as protein supplement in developing countries is very poor and at a very high price, This has led to use of non-protein nitrogen source as urea, to compensate for the nitrogen deficiency of fibrous feeds (Dutta et al., 2009). Thus, enhancing intake, digestibility and availability of nutrients from poor quality roughages are only possible through optimization of rumen fermentation. The use of solid multi-nutrient block supplementation /urea-molasses blocks/ multi nutrients blocks/ pashu chocolates to provide optimum levels of various nutrients primarily for better growth of rumen micro organisms. They need rich sources of fermentable nitrogen, minerals and vitamins, which are lacking in the fibrous feeds like cereal straws (Sahoo et al, 2009). This offer several advantages such as easy transport, storage and handling, and reduced risks of poisoning as compared with other approaches, such as giving a small amount of urea in drinking water, sprinkling of urea solution on fibrous feeds before feeding, or urea-ammonization of crop residues (Dutta et al ., 2009).

Fraudulent substitution of meat is the adulteration or mixing of the inferior or cheaper quality meat into superior quality meat. The first case of fraudulent substitution was recorded in thirteenth century A.D. at Florence in Italy. A common fraud in the meat industry in which uninspected meat is substituted for meat that has undergone inspection and been branded as satisfactory. The other frauds are the substitution of meat of another species, e.g. horse for beef especially in Britain and Ireland, beef in kangaroo meat in Australia, cat for chicken or rabbit, goat meat for mutton, mutton for venison, dog meat and cat meat for chevon in other countries including India. As per an estimate about 25-30% of meat sold in India is adulterated. These practices are more common in comminuted meat products. These illegal practices are punishable under PFA act 1955. The choice of method to be applied is depend on the need or condition of meat recovered.

Abstract

Drying is a widely used method of food preservation. It leads to some structural changes in the dried material resulting in poor quality and rehydration. Freeze drying, though a costly process, reduces water activity without exposing the food material to high temperatures, eventually retains the original quality to a great deal. Moisture in the foods is frozen to ice which is sublimated under low pressure. Low pressure helps to vaporise the ice without transforming it to liquid, hence leaving the food structure porous in nature. The food is claimed to preserve the nutritional, sensory and re-constitutional qualities.

1.1 INTRODUCTION

Most food materials are composed of a very high percentage of water, which can be as high as 95%, and this makes them susceptible to microbial activity. Microbial activity spoils the products, leaving them useless for human consumption. It not only changes their taste and color but it may also develop toxins, thus making them unsafe. There are various methods for preserving food but in order to make them shelf stable, removing water from foods helps keep them from spoiling for a longer period of time.

Freezing is one of the most critical stages in ice cream manufacture because it creates the frozen structure while simultaneously incorporating air. This chapter explains the principles of dynamic freezing and the structural changes that occur as the mix is transformed into semi-frozen ice cream. It discusses ice-crystal formation, air incorporation, overrun, draw temperature, fat destabilization, and product condition at freezer draw. Different freezer systems and hardening requirements are examined, along with calculations related to output and overrun. The chapter also introduces ingredient feeders and ripple or ribbon systems. Understanding freezing technology is essential for controlling texture, body, meltdown, yield, and overall product quality.

Introduction

The science of Biotechnology has been making every effort to create new opportunities for the welfare of humanity. Modern biotechnological tools are applied in India to boost fish production through aquaculture as well as conservation of the vast aquatic resources of the country for sustainable utilization. Transgenic technology is widely used in biotechnology, from the generation of genetically modified (GM) foods to the production of pharmaceutical proteins. This technology has been successfully used to develop fast growing super-fish stocks for aquaculture. The main reasons for genetic manipulation of species used in aquaculture are to enhance the growth and efficiency of food conservation, to increase tolerance to environmental variables like temperature and salinity, to produce new colour variants of ornamental fishes, to increase the resistance of species to pathogens, etc. Though the conventional selective breeding approach has proven to genetically upgrade rohu19, it is a rather time consuming process. Traditional selective breeding approaches in combination with transgenesis can bring about faster improvement of selected traits.

Abstract

Fruit leather is a concentrated source of nutrient, energy and minerals processed from fruits in the form of sheet or leather. It is eaten as a desert or snack since ancient time. Fruit leathers have a greater benefit than fresh fruits if equilibrium ingredients are established and seasonal surplus of fruits are utilized and contributed to minimize post-harvest losses. The process of making fruit leathers involve making fruit puree and adding additives and preservatives for the purpose of enhancing taste and shelf-life. Drying, the key unit operation in making fruit leathers, is the most energy intensive and time consuming step in the process, modern drying techniques can be implemented to overcome the limitations. By novel means of processing technologies or enrichment could lead fruit leather to introduce high quality food product in the market. Continuous research and development can lead to a new era of production and development of fruit processing and overcome the obstacles during processing. In addition study on chemical and biochemical hazards involved in overall process will guide to ensure product safety. Market research tools e.g. quality function deployment method and other market analysis methods could be applied to understand the product trend, demand, consumer expectations and the scopes of improvement.

Safe Food means

• It is not injurious to health
• It does not contain any filthy, rotten, decomposed or diseased animal
• substance or vegetable substance
• It is produced undermost hygienic conditions to produce/manufacture it, inferior or cheaper ingredients/raw materials are not used
• Food additives/processing aids used are permitted and are within prescribed limits.
• It is not misbranded

Labelling is a critical component of food regulation, consumer communication, traceability, and brand credibility. This chapter examines the regulatory requirements governing ice cream and frozen dessert labelling in India, with emphasis on FSSAI standards and declarations. It explains the distinction between product standards and label declarations and introduces systems for managing recipe masters, nutrition information, label copy, artwork, and packaging approvals. Mandatory declarations, ingredient information, allergen declarations, nutritional information, claims, and common labelling errors are considered. The chapter also identifies departmental responsibilities and best practices for label compliance. Proper regulatory control ensures accurate consumer information, reduces legal risk, and supports consistent packaging and commercial operations.

Recyclable Packaging Definition: Designed to be collected, processed, and used again in manufacturing, thus reducing reliance on new, raw materials.

Examples: Includes glass jars, metal tins, and crates for fresh produce transport. Challenges: Requires efficient collection and cleaning systems and may be unsuitable for single-use or sensitive items like fresh meat. Applications: Frequently found in beverage containers, food storage, and bulk food packaging

Abstract

A functional food is defined as food that provides health benefit beyond the basic nutrition. Such foods reduce risk of high blood pressure, coronary heart disease, osteoporosis, cancer and dental caries. Consumers’ increasing interest for maintaining or improving their health by eating specific food items has led to the development of many new functional foods including dairy products. These functional dairy foods contain some functional ingredients that decrease the absorption of cholesterol, reduce blood pressure and play role in regulation of satiety and have antimicrobial effects. Milk is a good source of fat, protein and minerals. It also contains several intrinsic functional components like melatonin, conjugated linoleic acid etc. in amounts lower than the body requirements. Fermented dairy products contain probiotics with special health benefits. Functional dairy foods could be produced with the addition and/or generation of functional components. Some examples include milk, yogurts and cheese enriched with conjugated linoleic acid or plant stanols/sterols to help reduce the risk of heart disease. Fermented dairy foods possess various nutritional and therapeutic properties. Lactic acid bacteria (LAB) play a major role in determining the positive health effects of fermented milks and related products. Dairy products with probiotics and prebiotics enhance digestive health, prevent colon cancer, help in lowering blood pressure and improve immune functions. Melatonin is important in curing of sleep disturbance and enhancement of alertness. Milk derived peptides have immunological, antimicrobial, ACE-inhibitory activity/antihypertensive, anti-carcinogenic and antioxidant activity. The aspects of functional dairy foods will be presented in detail.

Introduction

In terms of individual health and physical condition, the situation in modern society is rather giving rise to concern. The last decades have seen a tremendous increase in availability and variety of food products which has undoubtedly affected the food habits of the average individual. Despite the fact that food has become overall safer and increased accessibility allows for healthier diets, worrying we are nevertheless faced nowadays with diet- related diseases of proper epidemic proportions. We now encounter an epidemic of obesity that spreads not only to the majority of the adult population but also, more worryingly, to young people who have rarely the option of alternative diets. Moreover, as scientific proofs for the link between diet and disease (particularly cardiovascular diseases and some cancers) accumulate, action is urgently needed. There are an increasing number of calls for action. It is within this situation that functional foods have developed. They assume a highly targeted solution to the diet related diseases with effective reduction of risk and improved physical and mental well being. That represents a big step from the traditional food-for-nutrition but the scientific milieu is ready to take the chances. The emerging ‘functional food science’ is focusing research on the effects of functional foods on growth, development, metabolism, the cardiovascular system, intestinal physiology, and even on behavioural and psychological functions (FAIR, 2000, Vol. 1). In view of these facts, it should appear necessary to assess and evaluate the developments in food production in terms of their effect on the individual consumer and the society at large.

Abstract

Food is basic need of human for its existence. Food is a source of nutrients needed for growth, energy and protection. There are number of chemical compounds not considered as nutrients but has positive effect on health. There is a need to look into the health benefits of the food components. Many lifestyle diseases are caused by the unhealthy food habits. Developments in science have led to establish the link between food intake and healthy living. Non-nutrient compounds of food are also called phyto-chemicals. Functional foods are prepared by increasing a particular nutrient or phyto-chemical to get health benefits. The increased cost of health care and drugs trigger the developments in this area. The approximate global market size is 30 billion US$ while Japan, United States, and Europe are the leaders in functional foods. FICCI has reported that functional food market in India is worth Rs 4,400 crore with growth rate of 21%per annum.

Introduction

The food has been considered as source of nutrients in the past but increasing evidences has proved that particular types of food can help in preventing the diseases. The World Health Organization (WHO) has reported that deaths due to Non-Communicable diseases are increasing in South East Asian counties; where as CMPN (Communicable, Maternity, Prenatal, and Nutrition) are

Production: According to Food and Agriculture Organization (FAO) of United Nation, the global production of fruits and vegetables including melons was 638 and 1090 million metric tons while India produced 75 and 106 million metric tons in 2011. In addition to this, the world production of roots and tuber was 810 million metric tons whereas India produced 51 million metric tons in 2011. It indicates that fruits and vegetables form an important part of the diet in the world including India. There is an ample opportunity to manufacture various health promoting products based on fruits and vegetables. A number of Fruits and Vegetable based functional food that can be prepared and presented in (Table 1) indicates the role of fruits and vegetables in the nutraceutical production for their health benefits.
