Abstract

Functional foods and nutraceuticals are one of the fastest-growing segments of the food industry. The demand for these foods is driven by health conscious consumer and the growing awareness of the close connection between diet and health, particularly in relation to chronic diseases. Over the past five years (20082012), the Indian Nutraceuticals Market has been growing at a rapid pace and is expected to rise to US $ 5 billion by 2015. The rapid growth and development of this new industry combined with the need to protect consumer health and interests, has led to the evolution of a myriad of different regulatory frameworks and policies across multiple markets. Japan was one of the first countries to recognize a different category of healthier food products. The Japanese government formally accepted this category in the 1980s. Other developed countries viz. The EU, The US, Canada etc also regulated this sector during 1990s. In India, the Food Safety and Standards Act 2006 (FSSA) was enacted in 2006 in response to pressure from stakeholders and the food industry, transforming the regulation of food in India. Punjab state, with abundance of food grains and increasing trends in fruits and vegetables, provides options for both the producer and growth promotion in the nutraceuticals sector through partenship between research centers, private entrepreneurs and indigenous communities. Regulatory frameworks should focus on the protection of consumers, promotion of fair trade and innovation in the sector. This paper discusses functional foods and nutraceuticals as per food regulations prevalent in various countries and highlights how these regulatory frameworks play a major role in transforming the food sector.

INTRODUCTION

Food processing as a technological regime is undergoing a revolutionary change in terms of conception, product and process design and energetics. The conventional approach of a food processor is to develop products with a long shelf-life in user friendly packaging systems. Food processors are usually bothered about sensory attributes and microbiological profiles without much emphasis on the fate of heat labile nutritional and nutraceutical components. The changing consumer perception is slowly but steadily leading towards emergence of novel technologies without depending upon conventional thermal processing. A few years before, non-thermal techniques have emerged for food processing and preservation, but these techniques were restricted to framing of fundamentals with regard to the inactivation of vegetative and reproductive bodies of microbes and the deteriorative enzymes.

Milk production in India is a subsidiary activity of agriculture in contrast to the organized dairy sector in the western countries. Farmers and landless labour maintain one to five milch animals. As a result, small quantities of milk are produced in a scattered manner. Due to this reason, milk procurement models from western countries, such as bulk cooling and bulk transportation are not applicable under Indian conditions. Collection of small amounts of milk is scattered over long distances and, therefore, poses a formidable challenge in maintaining the quality attributes and keeping costs down.

3.1. Rural Milk Collection

A systematic approach to rural milk collection suitable for the tropical climate and techno-economic conditions prevailing in India has been developed, based on the indigenous experience gained over the past few decades. In the first phase, extensive surveys are undertaken in the milkshed areas, where the milk plant is to be established. The second phase involves ‘route planning’ taking into account, availability of quantities of milk, access to roads for plying vehicles and distance from the site of dairy plant. Then zones are identified, representing equal costs of collection and transportation. In the third phase, planning is done for locating the primary collection centres as well as chilling centres, where, milk can be cooled to 4ºC before transporting to the milk plant. Milk may be collected from individual producers either by the contractor or by forming village level cooperative societies.

In today’s innovation driven economies, turning a great idea or new technology into something investors want to fund takes careful planning. This process is called investor readiness. which means making sure the idea works, has a market, and is presented in a way that makes investors feel confident. Therefore, Investor readiness means the preparedness of an innovation to attract and secure investment from potential investors. It has all the essential parameters in place that an investor would evaluate before deciding to invest. For inventors, this means showcasing innovation’s business potential, potential for growth, and the capability to provide a return on investment. Understanding investor readiness is important because it directly influences scalability and growth of invention. Even the most innovative ideas can struggle to find the financial benefits without showcasing business potential.
Why it is important to discuss investor readiness
Investor readiness is the state in which a technology, its value proposition, and its founding team are significantly prepared to engage with securing funding from potential investors. Without investor readiness, even high-potential innovations may fail to reach the market due to gaps in business clarity, legal assurance, or team maturity. TTOs play an important role in this process by acting as intermediaries between inventor and investors. Modern day TTOs are more inclined to prepare technologies and associated teams to attract investment. This expanded mandate of TTOs and brought in investor readiness. It requires a wellstructured approach focused on aligning academic innovations with investor expectations. TTOs help in creating this readiness by guiding researchers through commercial pathways, derisking technologies, and translating technical advancements into investment suitable.

During the latter part of the 20^th century, rapid economic development in most countries coupled with population growth propelled the inevitable demand for more food and manufactured goods. However, requirement of more food is placing unprecedented demands on agriculture and natural resources. Humans have made agriculture the dominant environmental threat by clearing forests, cultivating marginal lands, and intensifying farming in sensitive landscapes and watersheds. Most of the land use systems in the tropics are characterized by a rapid decline in productivity and high rates of soil and environmental degradation which need to be addressed in a proper way.

Agriculture has changed radically since the end of World War II. Productivity of most crops has scaled to new levels because of the adoption of new technologies, machines, increased chemical inputs, and government policies. However, continuing agricultural production without harming the environment is a challenge, which must be tackled along with economic growth. Some of the environmental issues related to agriculture are top soil loss, groundwater contamination, air pollution, greenhouse gas emission, decline of family farms neglect of the working conditions of farm labourers, new threats to human health and safety by the spread of new pathogens, economic concentration in food and agricultural industries, and disintegration of rural communities (Brodt et al, 2011). This situation prompted world nations, political leaders, scientists and planners to pay more attention to the concept of sustainable development. As a concept, sustainability is concerned with the continuity of environmental economic, and social aspects of human society.

Abattoir : An establishment where animals are butchered is known as abattoir. It is also known as slaughterhouse. 
Abiotic : Abiotic means any factor which is not biological / abiological and especially there is no involvement of the organisms in synthesis of certain compounds.

The raw material of foremost importance in bakery product is the wheat flour. Bakery units prefer the flour obtained by milling in roller flourmill with 70– 72 percent extraction. Flour quality may be defined as the ability of the flour to produce an attractive end product at competitive cost, under conditions imposed by the end product manufacturing unit. The concept of quality differs from producer and consumer point of view. However, in general, the term quality may refer to fitness of a raw material or a product for a particular process or consumer. For a consumer, the following parameters are important criteria of a product quality.

Introduction

The green revolution which initiated in India during 1960’s to 1980’s was an attempt to overcome the then prevailing threats of food scarcity and lack of foreign exchange. The food scarcity was a result of severe drought which engulfed the country as well as the political situation it had to face after its short period of gaining independence (Reddy, 2010). The only way out to overcome the acute food scarcity was intensive agriculture, with the use of high yielding varieties, chemical fertilisers and pesticides which heavily boosted agriculture production in India. The remarkable increase in production and productivity resulted in non-judicious use of chemical inputs to extract the maximum from the degrading soil. This marked the era of soil, water and air pollution and extreme health hazards to all life forms.

Rachel Carson’s “Silent spring” in 1962 was an insight into the path of DDT the then prevalent pesticide through its effect on the food chain as well as the environment. She was one among the scientists to raise her voice against the indiscriminate use of pesticides. The evident impacts raised concerns over the continued use of chemical inputs (Lairon, 2010). The situation warranted the reduced or limited use of chemicals in agriculture which resulted in an “organic movement”. This caused a slow, but evident shift in the interest of growers and consumers towards organic agriculture for health security, food safety, quality and better returns (Niggli et al., 2007).

This review is an attempt to analyse the various factors affecting the safety and quality of organic food products in comparison with conventional food. Drawing a proper conclusion was a difficult task due to the limited availability of scientific papers published in this aspect, indication of only trends rather than solid proofs and non-revelation of non-significant data regarding related experiments. However, this review could evaluate the positive and negative aspects of organic cultivation and food production from the available data, so as to suggest measures for improving the quality and safety of organic food products.

It has been found that at the household level the health of female members in any family suffers to a large extent. It could be encountered to low health care, poor housing or/and environmental conditions. Due to malnutrition it affects the health to such an extent that it gives rise to many diseases. For a sustainable nutritional status food and various aspects of health needs attention. Looking into that, nutrition is directly related to the health status. For food and nutrition security it is vital to see the availability, accessibility and utilization of food. The World Food Programme (WFP) developed the Vulnerability Analysis and Mapping (VAM) project to analyse the vulnerability to food insecurity of target populations. A prominent part of VAM is related to food access. The demographic and Health Survey (DHS), funded by USAID, provides health data for many countries to help them design their national policy. FAO has developed the Global Information Early Warning System (GIEWS), which collects data related to temporary food insecurity. Under the leadership of WHO, several health surveillance systems have been developed and implemented to monitor the epidemiology of various forms of malnutrition and of selected diseases. At the meso or sub-national level, food market surveys provide data on the availability of food. Agricultural production surveys, intra-household food frequency interviews, immunization surveys and anthropometric surveys of children under five can be used to assess the availability, accessibility and utilization of food and its stability at micro level. Most common Food and Nutrition Security (FNS) indicators at different social and administrative levels depends on the supply and demand. To determine the national situation of food availability data on the production of different food commodities, fertility rate and the trends in internal population needs to be seen. Food prices and per capita food consumption are indicators for national food accessibility. The rates of stunting, wasting and underweight in children, low Body Mass Index (BMI) in adults and low birth weight are FNS impact indicators that designate the extent to which food is adequately being used, utilized and converted into a satisfactory national nutrition situation. Fluctuations and shortages of food availability or accessibility in food prices make the national FNS unstable. Sensitive indicators for accessibility of food are the prices in the market. The sewage disposal and diarrheal diseases (DD) rates affect food utilization.A temporal food and nutrition insecurity arises due to pre and post harvest food availability and accessibility along with low BMI.If the food is in shortage leading to the consumption of more wild foods indicates reduced food availability at household level. Also if the number of meals per day goes down and unemployment increases it indicates low food accessibility.Malnutrition indicators like wasting, goitre or anaemia among the household members show reduced food utilization at micro level. Finally, changes in pre-harvest food consumption practices are good indicators for temporal food insecurity.

Millets are highly nutritious and play a significant role in many people’s diets around the world. They have traditionally been transformed into a range of products through fermentation and malting for centuries. In the era of sustainable development, we still lag in using millets as a primary source of nutrition even after knowing that they are rich in terms of nutrition and other essential elements as compared to cereals. Today we have lots of information regarding different millets; nutrition content, methods of preservation, fermentation, malting, its products etc. Foods made from millet are regarded as potential prebiotics because they can improve the availability or functionality of probiotics, which has major positive effects on health. Foods have been fermented in order to enhance their flavor, texture and palatability. Although fermentation can result in a variety of products, the most prevalent ones are ethanol, lactic acid, carbon dioxide and hydrogen gas (H2 ). Commercial applications for these materials include use in food, vitamins, medications and industrial chemicals. Additionally, fermentation increases the amount of protein present, improves the accessibility of carbohydrates and reduces antinutritional components like tannin and phytic acid. Even though it has some drawbacks, such as the potential for contamination with dangerous microbes, fermentation technology is proven to enhance the nutritional quality of food products. This chapter covers the millet fermentation technology’s effects on the nutritional composition of the millets, contemporary developments in fermented millet-based products and technological improvements examined in the millet fermentation technology.

1. Algal Biomass

Algae is defined as heterogeneous assemblage of organisms that range in size from tiny cells to giant seaweeds, thus algae mostly are photosynthetic species which include eukaryotes and prokaryotic Cyanobacteria (blue-green algae) and live in aquatic habitats. They are ubiquitous in nature and are found in variety of environments ranging from soil, sand, marshes, brackish water, sea and fresh water. Most of them are capable of manufacturing their own food.

Microalgal research is offering wide potential in food biotechnology and is gaining more attention because of presence of wide range of bioactive and nutraceutical properties and added health benefits.The increasing population is one of the major growing concerns of today’s world. To meet the nutritional requirement of the rising population, researchers are looking for optional sources for food which are easy to cultivate, cost effective and produce large amount of bioactive compounds useful to prevent major diseases. Chlorella is unicellular green alga that is a potential source of nutrients like carotenoids, minerals, vitamins, and polyunsaturated fatty acids. Especially, omega-3 fatty acid and carotenoids have received considerable interests due to their roles in the prevention of chronic diseases. Lutein and zeaxanthin from Chlorella have been shown to be associated with eye health and function. Beta-carotene is known to reduce the risk of CVDs and certain cancers. Animal studies also demonstrated that Chlorella supplementation reduced the serum cholesterol levels.

Similarly, the blue green microalgae Spirulina, possesses diverse biological activities and nutritional significance. Regular consumption of Spirulina fortified food improves immune system by increasing phagocytic activity of macrophages, stimulating the production of antibodies and cytokines, increase accumulation of NK cells into tissue and activation and mobilization of T and B cells. Spirulina have also shown to perform regulatory role on lipid and carbohydrate metabolism by exhibiting glucose and lipid profile correcting activity in experimental animals and in diabetic patients. They were also found to be active against several enveloped viruses including herpes virus, cytomegalovirus, influenza virus and HIV. They are capable to inhibit carcinogenesis due to antioxidant properties.

Introduction

For many years it has been an elusive task to provide a precise definition as to what constitutes quality in wheat. Each country has its own traditions in bread and other bakery products. Quality will mean different things to a miller, a baker, a grain handler or a plant breeder. As the baking industry becomes increasingly specialized, specific qualities are sought. Even among those wheat varieties generally recognized as having desirable quality traits, the influence of environment can be substantial, and this necessitates a high level of skill on the part of grain buyers to survey the current year’s crop and blend the wheat for a specific end-use. This genotype X environment effect on quality also limits the capacity of end-users to source identity-preserved wheat from a narrow geographic area. Those of us engaged in the field of plant breeding are concerned primarily with those traits that can be manipulated genetically, and we study their stability under a range of climatic conditions. Constraints in time, cost, and sample availability usually necessitate the use of predictive tests during early generations, followed by milling and baking tests on advanced lines that have met a number of agronomic, disease and predictive quality criteria.

Introduction

Dough is a complex mixture of flour constituents, water, salt and other ingredients depending upon the requirements of end-products. It is the principal intermediate stage in the transformation of wheat into different end-use products. Rheological properties of dough determine the behaviour of dough during mixing, rounding and molding used in making different products and also effect on the quality of finished product. Therefore, understanding the various features of dough rheology and their relations with product quality is important. The importance is enhanced further because of mechanization and automation of baking industry. Dough is composed of continuous phase in which gas cells are dispersed. The continuous phase is called “dough phase”. It consists of starch granules embedded in protein matrix along with some lipids, cell remnants and yeast cells in fermented dough. Gas production and retention is the most comprehensive quality requirements of the dough for bread making. The ability of the wheat dough to retain gas during fermentation and oven rise is unique. This depends on the ability of the dough to be stretched into thin membranes because of protein phase.

Introduction

Wheat is the most important cereal crop to the human kind. It is the main source of energy and nutrition in human diet. Wheat is consumed in the form of large number of end products as chapati, bread, biscuit, cakes, pretzels, noodles and pasta products. Millions of people are involved in milling, baking and pasta products industry with huge turnover per annum. However, each end-use product of wheat has it’s own specific requirement for example basically hard wheats along with strong gluten and high protein content are used for bead making. Soft wheat with weak gluten and low protein content are required for biscuit making Souza et al. (1994). Durum (tetraploid) wheat is used for pasta products as macaroni, vermicelli and spheghatti and Dicoccum for therapeautic purposes. Often chemical improvers are used to improve the dough properties for these products. Most of these chemicals have been banned because of their toxic effects. Therefore, only alternative is to develop varieties suited to meet the requirements of these end-use products. This needs better understanding of molecular basis of grain quality to accelerate breeding for producing wheat varieties for each end-use product separately. Storage proteins are the major component of grain which determines end-product quality. In this chapter detailed structure, genetics and functionality of gluten proteins are described.

Introduction

The health and wellness continue to drive growth in the global food industry as the consumers are constantly looking for the foods, beverages and other dietary solutions that will help them more aggressively to meet their own unique nutrition and personal health goals. Worldwide countries are going through a nutritional transition and are now affected by double burden of problems like nutritional and food security. The common alarming problems are under nutrition and specific nutrient deficiencies simultaneously coupled with imbalanced diets and chronic diseases. The problem of chronic diseases, non-communicable diseases (cardiovascular diseases, respiratory diseases, diabetes, obesity, cancer etc.) and malnutrition is more serious in the developing countries. The lack of access to health services, sufficient income, healthy and nutritious foods characterize majority of poor people in developing countries. So, food is not only the solution but also viewed as a product to enhance health and wellbeing, and it encourages the producers by supplying new goods that meet these needs. From the past decade, there has been growing consumer awareness regarding health, nutrition and the food safety which are often triggered by specific food incidents, especially in the developed countries and high-income groups in such countries. In the food industry there have been two broad trends which are hazards in the food chain and nutritional profile of the food. There has been recognition that hazards and contaminants can enter the food chain and can cause sickness, death and diseases, and so governments, often to deal with consumer and industry concerns, establish regulations and standards on food hazards including standards on pesticides, antibiotics, microbiological hazards and other chemical and physical contaminants. On the other hand, there is also a growing awareness of the health-enhancing properties for prevention and treatment of health concerns beyond the basic nutritional component of many foods.

Furthermore, fermentation can be harnessed for waste management and environmental remediation, enabling the transformation of organic waste into valuable biogas. With ongoing advancements, fermentation technology continues to open new avenues for innovation and contribute to a more sustainable and environmentally conscious future. The present chapter compares types of fermentation process as well as gives an insight into various industrial prospects of fermentation technology.

Ice cream defects can result from formulation imbalance, poor ingredient quality, processing deviations, inadequate freezing or hardening, packaging problems, storage conditions, and cold-chain failures. This chapter provides a systematic framework for understanding, classifying, diagnosing, and correcting defects affecting flavour, body, texture, melting, colour, appearance, packaging, and storage stability. It emphasizes that a visible defect in the finished product may originate much earlier in the production or distribution chain. Examples include iciness caused by slow freezing or temperature abuse, weak body associated with formulation or overrun, and flavour problems originating from raw materials or microbial activity. Defect analysis therefore becomes an important tool for troubleshooting, quality improvement, training, and preventive action.

The cold chain is the lifeline of the ice cream industry because the product must remain continuously frozen from factory hardening until consumption. This chapter examines the complete cold-chain network, beginning with hardening and factory cold storage and extending through CFA or distributor cold rooms, refrigerated transport, retail freezers, and final consumer handling. It explains temperature requirements, monitoring systems, equipment selection, cold-room management, stock rotation, and quality assurance. Particular attention is given to Indian challenges such as power interruptions, inadequate freezer maintenance, poor retailer practices, and temperature abuse. The chapter demonstrates how disciplined cold-chain management protects texture, flavour, shape, overrun, shelf life, and ultimately consumer confidence

A greenfield ice cream project involves much more than installing production machinery. It requires integrated planning of the business model, market opportunity, capacity, product portfolio, plant layout, process technology, refrigeration, utilities, packaging, cold storage, quality systems, regulatory compliance, distribution, working capital, and future scalability. This chapter presents a practical framework for evaluating new ice cream manufacturing projects, with particular attention to a representative 1000 LPH facility. Different project scales and business models are considered along with major plant and machinery requirements. The chapter also highlights common project-planning mistakes and best practices. It helps entrepreneurs and investors assess technical feasibility, operational readiness, financial requirements, scalability, and long-term commercial viability.

Tamarind (Tamarindus Indica)

Introduction

The fruit of tamarind a pod 5 to 15 cm long, 3 to 10 seeds surrounded with edible pulp which is principal souring agent for sauces, chutney, in beverages and in general cooking. Pulp is carminative, laxative, given as infusion in biliousness and febrile conditions. It is also used in dyring and tanning and for polishing and cleaning metal ware. The tartaric acid is extracted from unripe fruits. The polysaccharide (jellose) is extracted from seeds, which is used as a sizing material in the cotton and jute industries. Besides, polyose obtained from the seed is good substitute for fruit pectin in the preparation of jam, jelly or marmalade. The bark and leaves are used for tanning. Tamarind balls are prepared after taking out seeds from the fruit. Tamarind paste and tamarind juice concentrate are the other commercial products.

The fruits, flattish, bean-like, irregulary curved and bulged pods, are born in great abundance along the new branches and usually vary from 2 to 7 in long and from 3/4 to 1 1/4 in (2-3.2 cm) in diameter. Exceptionally large tamarinds have been found on individual trees. The pods may be cinnamon-brown or grayish-brown externally and, at first, are tender-skinned with green, highly acid flesh and soft, whitish, under-developed seeds. As they mature, the pods fill out somewhat and the juicy, acidulous pulp turns brown or reddish-brown.
