All food legislation is predicated on the food law, which protects public health and consumers’ regarding food. The regulation is applied to stages beginning from producing the food, processing and finally distributing the food and feed, apart from domestic use by consumers.

Water is an essential component of all living things. Although once believed as a resource with a never-ending supply, it has now been understood that water is becoming increasingly scarce and therefore a proper management is necessary to keep a sustainable food production (Kannan & Anandhi, 2020). A continuous and safe supply of water is indispensable for the food industry where it has numerous applications along the agriculture and food production processes.

A healthy life is ensured by having access to safe, nutritious and balanced food. World health organisation (WHO) ensures its contribution in developing food safety systems that are sustainable to reduce health risks from farm to consumer. Thus, safe food, its quality and consumer protection are the priorities of this organisation (FAO and WHO, 2021)

Liberalized economies and evolving businessstrategies push variousindustries to achieve a competitive edge both in the domestic and international markets. Food industry especially, works on the bedrock of quality of products and services in order to attract and retain customers. In this new world of economic order, customers can select from wide range of products and services that are available in the market.

Growing population has increased the demand on food supply. Providing safe and hygienic food to the population is an essential consideration. Food safety systems and tools need to be in place to assure safe food, until which the food businesses would not flourish or be able to build their reputation. Food safety systems and management tools are important as they assist food business organizations to build confidence in people regarding food safety.

Safe, wholesome and nutritious food is vital for sustenance, good health, food and nutritional security and augmentation of sustainable development of an individual. Also, safe food helps in the growth of the national economy and enhances the trade and tourism sector. Foods that are unsafe containing various kinds of microorganisms can cause chronic diseases or illnesses varying from diarrhea to cancer.

Food is essential for human survival. It provides the required energy and vital nutrients for sustainable growth and development. With the increase in population and awareness, the demand for nutritious, fresh and healthy food also increases. Although adequate food is produced in order to meet the increased demands, it fails to reach the consumers in need due to food Food Storage and Preservation Practices   35 wastage and spoilage occurring during various stages of harvesting, food production, storage and transportation. Gajanana et al., (2009) stated that there is a mammoth wastage of food post-harvest. It is estimated that 20 to 60 % of produce are wasted during and after post-harvest. 

Food safety and hygiene has been an age-old concern. However, today it has become an important aspect due to the rise in foodborne illnesses for the past few decades globally. It is estimated by WHO that annually 600 million suffer from foodborne diseases as a result of unsafe food consumption while 4,20,000 deaths are recorded globally.

History of food safety starts with knowledge about food hazards. The term “safe food” can be defined from different angles since the end users are highly heterogeneous. However, the accumulating data and day by day emerging information aboutfood borne diseaseslead to a boom in public awareness about food safety. Food safety can be defined as “The strategies and activities aimed to protect foods from biological, chemical, physical, and allergenic hazards that may occur during all stages of production, distribution, and consumption” (Paperella, 2020). According to the World Health Organization (WHO), unsafe food,which contains hazardousmicroorganisms or chemicals, causesmore than 200 ailments, ranging from diarrhoea to malignancies among which diarrhoea is common. 

Food processing sector in India has largest segment of bakery with more than 1.3 million tonnes of production from organized sector and 1.7 million tons from 1,000,000 unorganized sectors. India is second largest producer of biscuits globally. Our bakery industry is positioned third in generation of revenues among processed food sector.

Confectionery is an vital food item of great acceptance among wide range of population. It has been relished as a major food delicacy from ancient times. The term confectionery is describes a spectrum of sweet goods and takes on different meaning depending on the country in which it is used, for example in the United Kingdom the term applies to any sweet product including cakes. In the United States confectionery is candy and includes sugar confectionery and chocolate confectionery.

Confectionery fills an especially direct need; the sugar of agreeableness joined with exquisite flavors, smells and mouthfeel affects a basically transitory feeling of thriving and joy. Sugar confectionery has been made all through the long haul with extending headway and it remain alive in unlimited plans following a changed levels of agreeableness, flavors just as scents, feel, appearance and tastes

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.

The history of cakes traces back to ancient times where Egyptians first practiced advanced baking skills. However, the modern-day cakes are said to have evolved in Europe around mid of 17th century. Today cake products and its derivatives are widely found all around the world. Cakes are sweet baked products rich in sugar, fat and egg with a tender bite and a pleasant flavour. They are basically protein foams, stabilized by gelatinized starch. Quality of cake depends on number of factors like selection of ingredients, balancing of recipe, optimum mixing and baking procedures. Good quality cakes are characterized by large volume, uniform crumb with fine cells and pore size.

The word biscuit drives from Danisbiscoctus which is the Latin word used for twice-cooked bread in Britain and refers to bread rusks made for sailors (ship biscuits) as long as the Middle Ages. Biscuits are thin, flat, baked and crisp items made comprising flour, sugar and fat as the key ingredients. These usually have a moisture content of less than 4% and have a long shelf life, maybe six months or more, when packed in moisture-proof containers. They may be a part of routine diets, sweets, luxury gifts, nutritional items, baby foods, pet foods, chocolates and creams added, etc. The appearance and eating qualities determine the appeal to consumers.

Bread is considered as one of the oldest processed foods to be known, traditionally prepared using wheat flour and water and baked on hot stones. The process of bread making involves hydration of protein and formation of gluten network ABSTRACT 70 Bakery and Confectionery Technology upon mixing, the evolution of carbon dioxide owing to the action of yeast on sugars and aeration of the mixture by incorporation of the gas followed by coagulation of the dough upon heating it in the oven. 

As the flow properties of liquids play such an essential role in our daily lives, whether intentionally or unintentionally, no one is truly an absolute beginner when it comes to rheology. Consumers not only focus on new and improved products but also consider the texture of the products e.g thick and creamy

Wheat (Triticum aestivum L.) is one of the major cereal consumed globally in various form as food. The powder of wheat flour is prepared by grinding of wheat seeds. Soft wheat flour has low gluten content that causes its crumbly texture. However, hard wheat flour has high gluten content of about 12-14% and has elastic toughness due to which it has good shape once its baked. Wheat flour is a basic ingredient in India’s famous flatbreads, and it can also be a key ingredient in addressing major health concerns in India.

The word “baked products” refers to a vast variety of foods, such as cakes, bread, cookies, pastries, and crackers, and a variety of other items, and it might be difficult to find a common thread that connects the members of this a varied group. The strongest common connection is that all of them include wheat flour in their recipes.

Bakery products have a long history of development. The process for the preparation of foods via dry heat treatments in an oven is defined as baking. Baking of foods can also be achieved by using hot ashes or on hot stones. Bakery products include biscuits, bread, cookies, rolls, cakes, pasteries, pies, rolls, doughnuts, etc. These products are mainly composed of raw materials such as wheat flour, water, yeast, salt, and various other ingredients. Bakery foods provide various nutrients that are beneficial for human health. Among bakery products, bread,biscuits and cakes are some of the popularly consumed items.

Millets are essential grains that help developing nations in Asia and Africa’s semi-arid tropics, particularly India, Nigeria, and Niger, achieve food and nutrition security.They are grown on soils that are usually too weak for any other crop to grow. They can withstand drought, minimal fertiliser treatment, and temperature swings better than other cereal crops, and their short growing season makes them exceptional. Millets are all-season crops that can be grown all year and provide several security benefits (food, feed, health, nutrition, livelihood, and the environment), making them the most cost-effective agricultural security crop. Sorghum (Great millet), Bajra (Pearl millet), small millets such as Korra (Foxtail millet), Ragi (Finger millet), Kodo millet, Proso millet, Little millet and Barnyard millet are all important millet crops grown in India.

Vegetable oils and fats play a very important role in our diet. They provide essential fatty acids which are precursors of important hormones such as prostaglandins. They control many physiological factors such as blood pressure, cholesterol and reproductive system [1]. Coconut oil is a popular vegetable oil obtained from kernel of fruit coconut (Cocos nucifera). It is liquid at room temperature and bland in taste. Coconut oil is extensively used in cooking purpose in coastal tropical regions although it has been used in abundance for its medicinal properties.

Cooking oil when heated there will be some changes like its colour, flavour, smoke formation etc. One change is the change in total polar compounds (TPC). TPC is used to measure the quality of oil. The TPC value increases with the reheating of oil, higher TPC value means the oil having high contain of peroxide and hydro peroxide. FSSAI fixed the value of TPC at 25%, beyond of this value the cooking oil can causes health issues like hypertension, atherosclerosis, Alzheimer’s disease , liver disease even liver cancer.

Snack foods have become an essential part of the diet throughout the World and they are prepared from natural ingredients or components to yield products with specified functional properties. Extrusion cooking technology getting more popularity over other traditional processing technologies because extrusion shows continuous efficient cooking, mixing and forming process.

Quinoa (Chenopodium quinoa Willd.) is a part of “Chenopodiaceae” family. Up to 250 species of Chenopodium have been identified to date. Quinoa is a South American grain that has been farmed in the Andes for thousands of years, particularly in Peru and Bolivia. It is considered as a sacred plant because of its abundance in protein and essential amino acids (Jancurova et al., 2009). Quinoa is distinguished by its excellent adaptability to a diverse variety of land and environmental variables. Both leaves as well as the grains are considered as the edible parts. However, the quinoa grains have been extensively studied and economically explored (Rocha, 2008).

Developing a nutraceutical or functional food is becoming mandatory as looking at the current nutritional status of the population over the world. Nutraceutical foods are proven to cause several health benefits to people. Hence the basic aim behind developing the nutraceutical chocolate bar was to fulfill the nutritional demands and provide some additional benefits to people. The product mainly contains two key ingredients that are, Drumstick (Morings oleifera) which has the most qualities to call a Superfood” and Quinoa (Chenopodium quinoa) which is referred to as “Mother of all grains”.

Cellulose is a homopolymer of β (1–4) glucose linkage. It is the most abundant polymer present on the surface of the earth, which is mainly produced by the vascular plants (Sharma et al., 2019; Dayal et al., 2013; Sheykhnazari et al., 2011). Cellulose obtained from higher vascular plants has been employed for making textile and papers.

Wood apple (Feronialimonia) commonly known as Bael in various Indian sub-continent languages is the most under-utilised fruit despite of its aromatic flavor, high nutritional components and important medicinal values. Reason may be due to challenge in harnessing the pulp from the fruit. It is considered under seasonal fruit but it has long duration of shelf-life as compared to other fruits.The physic-chemical characteristics revealed that it has high shell weight of 55.67% as compared to pulp weight of 43.77% (Devi et al. 2018).

Dehydration (or drying) is defined as ‘the application of heat under controlled conditions to remove the majority of the water normally present in a food. The main purpose of dehydration is to extend the shelf life of foods by a reduction in water activity. This inhibits microbial growth and enzyme activity, but the processing temperature is usually insufficient to cause their inactivation. Therefore any increase in moisture content during storage, for example due to faulty packaging, will result in rapid spoilage.

Studies have shown that modified atmosphere packaging (MAP), and controlled atmosphere storage have the ability to delay quality losses and thus extend shelf life of fresh or minimally processed or fresh-cut produce (Church 1994; Gil et al. 1996a, b; Lee et al. 1995). Modified atmosphere packaging of fruits can result in reduction of respiratory activity, delay in softening and ripening and a reduced incidence of various physiological disorders and pathogenic infestations (Artés 1993).

Abstract

The objectives of the study is to help to create self-employment and provide proper information for different conventional milk based products. Traditional dairy foods have always played a crucial role in preservation of precious milk nutrients and promotion of its use among masses. The demand for milk and milk products is increasing with increasing of world's population. To meet these needs, high-end technology is needed for emerging the capability of milk production and preserving it by producing high quality milk products. The dairy industry is highly localized owing to perishable nature of milk products. Approximately 50% of the total milk produced in India has been projected to be processed into a variety of conventional milk products, such as khoa, chhena, paneer, dahi, ghee, kalakand and a wide range of sweets in rural areas mostly by the rural citizens. Therefore, setting up a milk-based food production system and updating conventional technologies to manage milk-based products on a commercial scale is very important.

Jamun (Syzygium cuminii L. Skeels) is an evergreen tropical tree which belongs to family ‘Myrtaceae’. It is commonly known as java plum, jambul, jamun, black plum, faux pistachier, Indian blackberry, doowet and jambolan. Jamun is native to the subtropical Himalayas, India, Sri Lanka, Malaysia and Australia. Its fruits are delicious and have great importance in folk medicine (Ayyanar and Subash, 2012).

Food and nutrition are necessary for all living beings to maintain good health[1]. Thermal treatment is commonly used for preservation of food. Although application of thermal treatment can ensure food safety, it may cause undesirable changes in the nutritional, sensory and functional properties of food products[2]. Due to growing awareness of connection between the diet and the health, there is an increase in demands for fresh-like, palatable, additive-free and microbiologically safe food products with high nutritional value and quality[3].

Food preservation methods are important in order to avoid glut or shortage of food in the market. In addition it helps to increase the shelf life, maintain the nutritional and sensorial quality, facilitate transportation and improve the overall value of the commodity. Even though various methods of food preservation are available now. Most of the conventional methods are thermal preservation methods which may result in the loss of volatile nutrients and flavour, different sensorial modifications, microbial spread with or without gas production, damage to the microstructure, rupture of coating or packaging surfaces and microbial recontamination caused by non-hermetic closure.

A number of quality management tools are being used in food processing industry. Often selection of such tools are tough as it involves several factors for decision-making. The problem of choice of quality management and tools can be solved by selection on the basis of the objective decision making process rather than on the opinion of the decision makers (Sukkarn and Thawesaengskulthai, 2015).

Probiotics have been newly defined as ‘live microbes which passage the gastrointestinal tract and in doing so benefit the health of the consumer differing from the earlier definitions which focused on probiotic interfaces with original intestinal microbes (Fuller, 1989). These definitions of probiotic bacteria generally agree that probiotic bacteria should be living organisms toward consult health benefits. Probiotics have been reported to play a therapeutic role by modulating immunity, lowering cholesterol, improving lactose tolerance and preventing some cancers (Kailasapathy and Chin, 2000).

In India after rice wheat (Triticum aestivum L.) is the second most important cultivated food crop belonging to family poaceae. Total production of wheat was 760 million tons in India during 2016-2017 (FAOSTAT, 2017) which is second largest in the world after china. In India highest producing state of wheat is Uttar Pradesh followed by Punjab, Haryana, Madhya Pradesh, Rajasthan etc. Wheat is categorize into seven commonly known wheat classes those are hard red spring, hard red winter, soft red winter, hard white, soft white, durum and mixed wheat (Khamis, 2014). 

Most of the starch sources are cereals (40 to 90%), tubers (65 to 85%), roots (30 to 70%), legumes (25 to 50%) which contain nearly 70% of starch on dry basis (Santana & Meireles, 2014). Major application of starch is seen in food production, where it is used as a thickening agent, for stabilization, adsorption, gelling, for binding aromatic compounds and as a film forming agent as well (Subaric et al., 2007). About 0.8-3.2 tons of CO2 per ton of plastic can be saved by using starch-based plastics (Patel 1999).

Drying is basically the unit operations which is used in many of the food industry nowadays. It can be desirably known as the process of removing moisture to relent a hard products. It is the transfer of energy source, mostly it derives heat from the outer environment to the dryer in which the food products is placed.

As a result of a number of health advantages provided by functional foods, a substantial rise in their popularity has been seen in recent years (Keservani et al., 2010).

Diverse categories of Food Products such as canning, preservation of fruits and vegetables, processing of poultry products, dairy goods and many more present different challenges for wastewater disposal and regular use of water. A significant source of environmental pollution is the dissipated water generated from food product development and other agricultural tasks. This waste is being considered the most strenuous and requires a high amount of capital to convert this waste into reusable waste and the main reason behind this is different nutritional components such as inorganic and organic carbon compounds, nitrogenous elements, suspended and dissolved solids, high amount of biochemical and chemical oxygen demands (BOD & COD).

The proposal presented takes into account the rationale of using natural source of immunity, discarding any preservatives or artificial flavors and additives. Collection of fresh produce followed by processing of fruits and vegetables, in the form of a veggie mix slushy which is ready to eat, ready to cook and easy to digest, through the use of sustainable retorting technology. The proposal takes into account the major problems regarding food for the elder like lack of digestion, in sufficient appetite, lack of value in terms of vitamins and minerals of food, also targeting the notion of feeling sick by taking multi vitamin and immunity tablets on a regular basis.

In India the problems of protein energy malnutrition, anemia, and vitamin A deficiency are more prevalent among children and adolescents (Udayasree, Manjula, & Sowjanya, 2013). To overcome these problems, the need of nutritional compositions rich foods came into existence. One of such foods which constitute the most significant attention of nutrients is “Spirulina”. Spirulina is a common name for supplements derived mainly from two Cyanobacteria species, i.e. Arthrospira maxima and Arthrosepira platensis, which are human and animal.

Fermentation is one of the ancient techniques that been routinely used to maintain the quality of food products. This process involves the breakdown of complex substances like carbohydrates into smaller ones which assist in extending the shelf life of food products. Fermented foods and beverages shared the major portion of the human diet which positively affect the body. Beer is a low alcoholic drink in which malt, hops and other adjuncts like aromatic herbs, honey and others are fermented with yeast to obtain a product that offers unique flavour, taste and aroma (Sohrabvandi et al., 2012).

Lanolin, commonly known as Wool grease is primarily a lipid secretion from sebaceous glands of wool bearing animals. The role of Lanolin in nature is to protect wool and skin of animal from climate and the environment. It is an excellent emollient, self-emulsifying and dermatological safe for skin applications. Lanolin is a complex matrix since it is a mixture of high molecularweight esters of fatty acids with fatty alcohols, sterols, tri-terpene alcohols; diesters, long-chain alcohols & diols, long-chain fatty acids and hydroxy acids and is therefore difficult for effective matrix clean-up. Because of its water proofing and antimicrobial properties, lanolin is used mainly in cosmetic and pharmaceutical applications.

Most traditional food processing techniques like boiling, cooling, freezing, and blanching are used in a home kitchen. But now-a-days, food processing and preservation industries combine these techniques with other processing operations by using different technical prospects. As a subset of traditional processing technologies, modern processing technologies include hot air sterilization, vacuum cooking and pulsed electric-field technology as well as high pressure treatment, extrusion, microwave processing, and pulsed electric field technology.

Pre-harvest factors are responsible for the majority of post-harvest losses. Fruits which have already been infected with insects and pathogens, have been poorly irrigated and fertilized, or are of low quality before harvesting will never benefit with post-harvest cures. As a result, the process of accomplishing production quality, as well as harvesting, processing, and selling, must be taken into account.

Fruits are an essential component of a human’s healthy diet. Fruits are used as a supplement to primary foods. When compared to grains, many fruits have far greater nutritional potential. The common fig is one of the most important and widely consumed fruits (Ficus carica).
