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 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.

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.
