ABSTRACT

Malting is the process accompanied by restricted sprouting of cereals in humid atmosphere along with controlled set of conditions. It is a process of soaking, germination and drying that causes changes to the microstructure of grains. Malting causes changes in functional and nutritive value of grains. Malting results in increase in protein content, mineral availability, in vitro protein digestibility, oil absorption capacity, water absorption capacity, water solubility index and fall in level of antinutritional factors, viscosity and bulk density. The malting conditions are significantly affected by varietal difference, maturity of grains and structural composition. Therefore, optimum malting conditions should be determined for grains in order to avail the health and nutrition benefits.

Introduction

The health and wellness of human being is largely dictated by the consumption of nutritious foods. Understanding the role of foods in maintaining health and cure of diseases has its roots in the ancient Hippocratic and Vedic texts as well as in the canons of Traditional Chinese Medicine (Sharma et al., 2012). Presently, the transition from a traditional to modern lifestyle, consumption of diets rich in fat and calories combined with a high level of mental stress has been the major cause of lifestyle related diseases like coronary heart disease, obesity, diabetes, cancer and hypertension (Moczara et al., 2012; Sharma et al., 2018). Various studies have linked foods as helpful in combating a number of such degenerative diseases (Sharma, 2015).Therefore, the tenet "Let food be thy medicine and medicine be thy food", quoted by Hippocrates about 2,500 years ago is receiving overwhelming interest. There are number of scientific reports emphasizing the importance of consuming biologically active ingredients present in fruits, vegetables, whole grains and legumes to reduce the risk of chronic diseases (Hasler 2002; Das et al., 2011; Sharma and Sharma 2016). Such biologically active ingredients are now popularly known as neutraceuticals. Whereas, the functional foods are the foods that resemble traditional foods but possess demonstrated physiological benefits. In some countries, however, functional foods and nutraceuticals are used interchangeably. Regardless, the main focus of such products is to improve health and reduce disease risk through prevention. The main difference of this category with pharmaceuticals is that they are multi-targeted mixtures and present at low concentration while pharmaceuticals are uni-targeted pure compounds with high dose use. Hence, an overview on the concept of nutraceutical and functional foods, their classification, development and regulations is summarized in this article.

Introduction

Hormones may be defined as specific chemical molecules produced in certain specific organs called specialized cells or endocrine glands. They are delivered into the blood stream or some other body fluid in minute amounts by the circulatory system of the body and their they exerts a physiological effect at a site of action remote from its origin, regulating numerous biological activities including growth, development, reproduction, water & electrolyte balance, storage & usage of energy etc.

Introduction

Irrigated agriculture plays a predominant role in the state’s food grain production. Erratic trend of rainfall, it has been realized that the availability of water will become very less in forthcoming days as a result cultivation of crops will face water crisis. Development of new water resources needs excessive money investment with high level of expertise and technical knowhow. The ground water is also falling down to greater and greater depth due to overdraft causing for the restriction of the construction of tube wells. Further the efficiency of traditional irrigation system in India is now varying from 30% to 40% against 62 to 65% during the project plan periodbecause of wastage of this valuable water resource due to mismanagement. To meet the increasing demand for additional food grain production, the demand for water in the irrigation sector will increase substantially. In such a situation conservation of water and its proper management is necessary for developing a sustainable agricultural system avoiding the degradation of the land quality, water and other natural resources in an irrigated area.

INTRODUCTION

Food being the basic need of all humans and other living organisms, the production and processing of food is a continuous activity with several new procedures and technologies adoption; thereby the quality of food needs an emphasis which also protects the consumers by providing safe and suitable food. The contaminated foods, food borne illness outbreaks though at times referred to poor consumer handling, commitment for provision of safe food to consumers is also a Governments concern. In the recent years, food safety measures through Food Safety programmes and increase in awareness are being followed. The food production in our country is the most promising sector which is the cause for white revolution and green revolution. India ranks first in the world in production of cereals and milk and second largest producers of fruits and vegetables. India stands second in inland fish production. It is second largest exporter of rice and so on. Food processing sector has a great potential which covers a wide spectrum of products encompassing agriculture, horticulture, plantation, animal husbandry and fisheries. But the growth of food processing industries in our country is rather slow. However, to encourage, the government is providing lot of incentives in the recent years.

Introduction

The diverse cluster of naturally occurring organic compounds including fats, oils, fatty acids, waxes, phospholipids, eicosanoids, terpenes, steroids and fat soluble vitamins that do not prefer to interact with water but soluble in non-polar organic solvents like ether, chloroform, benzene, acetone, are called as lipids. The main functions of lipids in biological system include storage and transport of metabolic fuel, structural component of cell membranes, insulation & protection of vital organs from shock and carrier of fat soluble vitamins. Contradictory to proteins,lipids are not polymers in nature and are hydrophobic due to presence of a long hydrophobic chain. Apart from this, lipids also act as precursor molecules for several pigments, hormones and signaling molecules.

Incentives are a powerful stimulus to transfer of technology. They can encourage researchers to get their results to market, a new career path for many of them. They can create a culture that attracts and retains entrepreneurial staff, scientists, students and technology transfer professionals (TTPs) that view the university as a career path and a vehicle for making a contribution to society. Working in a pro-entrepreneurship team of colleagues can also lead to getting people to think in terms of making a connection between their work and its application. Incentives can be short-term or long-term in nature, and can be tailored to individual or collective requirements. As it is likely to be challenging for universities to design incentives that cater to every researcher’s or TTP’s desire, they can design incentive programs to cater to various aspects of human. Nature.
12.1 Why incentives matter in this ecosystem
Incentives can be either financial and non-financial. These are needed to ensure that researchers and TTPs remain motivated, aligned with institutional goals, and committed to the long-term process of technology transfer and commercialization. Incentive programs serve several important purposes:
• Motivation: Incentives energize individuals to pursue innovation and commercialization, often over long- and uncertain-time horizons.
• Retention: By offering recognition, rewards, and career advancement opportunities, institutions can retain high-performing researchers and skilled TTPs.
• Alignment: Well-designed incentives ensure that the personal goals of stakeholders align with institutional and societal objectives.

1. Introduction

The development of food products using composite flour has increased and is attracting much attention from researchers, especially in the production of bakery products and pastries. This article focuses on the use of composite flour to produce food products, namely bread, biscuits, and pasta, with looks at on its impact, following some improvements made, on the sensory quality, rheology characteristics, and nutritional values as well as its overall acceptance. The blending of wheat flour with various sources of tubers, legumes, cereals and fruit flour in different percentages to produce variety of food products are also reported. The positive effects of the use of composite flour can be seen in the final product related to the functional and physicochemical properties and health benefits of raw blended flour along with percentage blending. Overall, composite flour is a good new approach to utilizing uncommon food products as the application of composite flour produced products with different characteristics and quality, depending on the types and percentage of wheat flour used in the formulation.

Bread has been the staple food worldwide and habit of bread is derived in part due to the convenience and wholesomeness. Wheat is a commonly used cereal for making bread as it gives the desired texture due to the presence of gluten forming proteins like gliadins and glutenins (Decock & Cappelle, 2005). In earlier times idea of composite flour in developing countries originated in order to cut down on import of wheat (as it was not grown in many countries) but in recent past refined wheat flour consumption has lead to health issues and thus in order to improve nutritional and functional properties composite flour has been the norm. Composite flour is the one obtained by mixing wheat flour with cereal and legume flours for making bread and biscuits (Dendy, 1992). However, mixing of non-wheat flours, roots and tubers, legumes or other raw materials can also be regarded as composite flour.

Sugar confectionery and chocolate includes candies (sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of sugar confections. The words candy (US and Canada), sweets (UK and Ireland), and lollies (Australia and New Zealand) are common words for the most common varieties of sugar confectionery. Confectionery depends on numerous ingredients which have been discussed in detailed in this chapter

Introduction

Packaging helps to maintain the benefits of food processing and enables safe transportation of foods from their point of origin to point of consumption without compromising the wholesomeness of processed food in terms of its physico chemical and microbiological quality. However, packaging technology must balance protection effects with environmental issues, material and energy costs and should comply regulations on municipal solid waste disposal and release of pollutants. These regulations are different in jurisdictions around the world.

Safety implications of food packaging raise concern in recent times due to advances in technology leading to variety of packaging materials and additives. Also there is an alarming situation of damages to environment and natural resources of the planet, due to indiscriminate use and disposal of packaging materials.

However, food packaging as a means to protect and preserve food integrity, to enhance its shelf life and improve consumer appeal cannot be overlooked.The applications of food packaging and its primary role to protect and preserve food has remained the central focus of packaging innovations.Packaging materials are available in variety of forms and are made up of variety of ingredients.While paper. While paper, plastic, petroleum based materials have been in use for many years, the recent approach is towards environment friendly options from agricultural produce such as plant fibres sugars and starches. Advances in packaging has led to development of newer materials and combinations with specific economic and functional benefits.Food packaging ,in general , provides the ability to withstand thermal processing and acts as a barrier against light, moisture,oxygen and other sources of contamination.

MAC : It stands for modified atmospheric coating.

Macaroni : Pasta made from semolina and shaped in the form of slender tubes.

Macaroni wheat : It is tetraploid wheat and is preferred for making macaroni, vermicelli etc.

Macaroon : A small cookie composed chiefly of egg whites, sugar, and ground almonds or coconut.

Mace : An aromatic spice consisting of the dried external fibrous covering of a nutmeg.

8.1. Introduction

Food packaging’s essential functions is to protect the food from hazardous compounds, and contaminant. In order to improve the shelf life of food commodity, smart packaging like active and intelligent packaging has been developed which can monitor freshness, display information of quality, and improve food safety. More precisely, smart packaging was defined by Smart Packaging Journal as “the use of features of high added value that enhance the functionality of a product, notably mechanical, electronic and chemical features that improve safety and efficiency”. The major concerns with traditional packaging are not only shelf life of packaged food, but also the inability of packaging material to convey the important information about quality changes to both customer and manufacturer. 

The art of confectionery manufacture date back to over 3000 years as per Egyptian records. Traditionally honey, boiled and concentrated sugar cane juices have been used in confectioneries. In modern times, alternative sweeteners from sources like corn and starches constitute an integral part of confectionery manufacture.

Owing to the huge variation in finished products as well as raw materials in food sector, Quality control has an extremely important role to play. Quality control aims at controlling variation to within a tolerable level by taking corrective actions. Statistical and non-statistical techniques are employed to measure, analyze and control variation in food products. Statistical process control, acceptance sampling and visual inspection are widely used in food and allied sectors.

Maintenance of quality and manufacture of a standard confectionery should involve a very close control of raw materials, instrumentation, and statistical analysis of finished product. Statistical evaluation with respect to finished product includes weight control, sensory evaluation and packaging tests. The quality standards are set by the quality control departments. Chemists may undertake preliminary analysis through visual inspection. Visual inspection is usually combined with sampling. This gives an idea of variation, cleanliness, infestation etc. in the sample.

1. Introduction

Now a days, foods are not intended to only satisfy hunger and to provide necessary nutrients but also to prevent nutrition-related diseases and improve physical and mental well-being of the consumers (Menrad, 2003). In this regard, functional foods play an important role. The concept of functional foods which has evolved as the role of food in the maintenance of health and well-being and in the prevention of disease, has received increased scientific and commercial interest is recent past. Growth of functional foods markets include increased consumer health awareness, increased popularity of healthy foods, search for food-based drug substitutes, self-medication approach promoted by busy lifestyles and rapidly developing health conscious markets. Functional foods can be defined as foods “that can beneficially affect one or more target functions in the body, beyond adequate nutritional effect, in a way relevant to an improved state of health and wellbeing and/or reduction of risk of disease” (Stanton et al., 2005).

T A Spoilage : The spoilage of low and medium acid canned foods by Clostridium thermosacharolyticum which breaks sugars and form acid and gas (moisture of H₂ and CO₂) resulted in swelling and in severe cases even bursting of can may occur and the spoiled food usually has a sour odour.

Introduction

There are large numbers of wheat based products such as fermented pan bread, flat breads including chapati, biscuits, noodles and pasta products. Each product has its own specific requirements. For example fermented pan bread needs wheat with higher protein content, stronger and extensible gluten. Chapati requires hard wheat with high protein content and medium gluten strength. Waxy wheats have been found associated with improved shelf life of breads. White salted Japanese noodles need partial waxy wheats with soft grain characteristics and medium protein content and gluten strength. Partial waxy wheats with comparatively lower amylose content and higher starch paste viscosity improve texture of white salted noodles. Yellow alkaline noodles need comparatively harder wheat with medium strong gluten and without waxy trait. Pasta made from durum wheats requires stronger gluten, high protein content and higher content of yellow pigments. In this chapter detailed account of both fermented and flat breads will be given.

1. Introduction

A confection is sweet tasting delicacies developed using sugar and other carbohydrates with optionally selected chocolate, nuts, fruits, vegetables or gums. Depending on the formulation, the confection may vary from sugar boiled hard lozenges to gum based soft gummy toffees, from chewing gums to mouth melting chocolates. The versatile and broad variation in the product created by differentiating flavours, ingredients and processing has greatly influenced the market demand of these products. Although confection is non-essential commodity but still relished by people of all economic strata and hence creating a great market space and scope of new products.

In confectionery research and development area, current popular sector is functional confections. The sector has been on the trends radar globally, accounting for 8% of the global confectionery market, and most accepted and successful in Japan.

Ice cream is a complex multiphase food system in which fat, proteins, sugars, water, air, ice crystals, and stabilizers interact to determine its structure and eating quality. This chapter introduces the scientific principles governing ice cream composition, microstructure, freezing behaviour, and processing. It explains freezing-point depression, ice-crystal formation, colloidal behaviour, foam development, and structural changes during processing. Particular attention is given to the relationship between microscopic structure and sensory properties such as smoothness, creaminess, body, and meltdown. By connecting food chemistry with processing technology, the chapter establishes the scientific foundation required to understand formulation, manufacturing performance, quality control, and product stability.

Abstract

The natural color of foods is due primarily to carotenoids, anthocyanins, betanin and chlorophylls, either as inherent food constituents or as food or feed additives. These compounds have drawn considerable attention in recent years, not because of their coloring properties, but due to their potential health-promoting effects. Their occurrence and levels in foods, along with the factors that influence the composition, have been widely investigated. Processing effects have been actively studied. In spite of the intense search for plant and microbial sources and efforts to increase yield, few natural food color additives have reached the market. Developing new colors for the food industry is challenging, as colorants need to be compatible with a food flavors, safety, and nutritional value, and which ultimately have a minimal impact on the price of the product. In addition, food colorants should preferably be natural rather than synthetic compounds. Micro-organisms already produce industrially useful natural colorants such as carotenoids and anthocyanins. Microbial food colorants can be produced at scale at relatively low costs. This chapter highlights the significance of color in the food industry, why there is a need to shift to natural food colors compared to synthetic ones and how using microbial pigments as food colorants, instead of colors from other natural sources, is a preferable option.

Abstract

Probiosis has emerged in the early 20^th century after Ellie Metchnikoff proposed his hypothesis that organisms were reponsible for longivity of ethnic people of Balkan region of Russia and ever since it has grow into a major scientific field which has its applications extending into farming, aquaculture and prophylactics in humans. Vast research was carried out on this topic and Lactobacillus sp. and Bifidobacterium sp, are the two important genus that are highly studied and widely recognized universally as conventional probiotics. Apart from these two genus there exists many other bacterial species which have shown promising probiotic potential. Such non conventional probiotics are widely used in some parts of world as commercial food products with health beneficial effects, pharmaceutical products or being tested for their safe utilization in human beings. The present chapter tries to covers some genera and their potential and application in prophylactics.
