   Preface

   Assuring safety and quality in food supply chain is one of the key drivers in the stride of food industry to keep pace with the ever demanding global standards. The benchmarks of food safety and agricultural health standards set in developed countries often pose major challenges for developing countries to succeed in international markets for high-value food products, such as fruit, vegetables, fish, meat, milk and grains. Undoubtedly, this calls for enhanced competitiveness of food technologists, scientists and entrepreneurs. In this context, there is a burgeoning demand for updated research and development to identify and control food safety hazards, and to deal specifically with analysis of food quality and safety. The laboratories need to be strengthened in terms of infrastructure facilities, manpower, and systems to detect hazards in food supply chain. With the technological interventions in food quality analysis and safety detection advancing at tremendous rates, the industry and academia need to be competitive in delivering value added food products without compromise in safety and quality.

   In this backdrop, it is essential that the current procedures and protocols in the areas of safety and quality analysis/detection be made available in an easy to read format for the benefit of the students, analysts and researchers. This book is a comprehensive documentation of both agriculture and animal food segments which confers it a unique status among the various publications in post harvest sector. The content of the book is useful both for those looking to begin food science careers and to established specialists. Besides the special emphasis on safety and quality of fruits, vegetables, tropical tubers, plantation crops, spices, bakery and confectionery, the chapters on water quality and safety attributes of meat as well as dairy industry have been designed to fill up the void in integrated strategy development protocols. Due importance has also been given to elaborate the various invasive and non invasive detection protocols to analyse the safety of foods of animal and plant origin. The contents of the book speaks of the prudent vision of the contributors to blend science and literature so that it can easily be comprehended by an undergraduate student, is a knowledge platform for post graduates and serves as an enriching guide for researchers. The authors of each chapter have presented the quality and safety aspects of each commodity in a subtle manner along with the existing regulations, wherever applicable.

   We place on record, our deepest gratitude to all the contributors of this book whose efforts has woven a unique and comprehensive document to serve the food industry. The guidance and support of Dr. K. Alagusundaram, Deputy Director General (Engg), ICAR, New Delhi, Prof. R. Chandrababu, Vice-Chancellor, Kerala Agricultural University, and Prof. M.R. Saseendranath, Vice-Chancellor, Kerala Veterinary and Animal Sciences University, have kindled our spirit and we remain grateful.

   Conscientious efforts have been registered to present the updated technologies of food safety and quality in the most befitting perspective. However, creativity is not without flaws....productive criticism is always welcome.

   Introduction

   Food safety and quality assumes paramount significance in any food industry. Globalization has driven both the food and agricultural firms to adopt systems that functions in a way to interlink food standards and international trade so as to achieve superior food quality and safety. Food industries follow several regional and international food safety procedures to procure certification from the government and other agencies in order to survive in both domestic and international markets (Ryan, 2014). The essential components in the food safety include handling, preparation and storing of the food products to ensure the food quality and to avoid food-borne diseases. The unwanted substances in a food product included by an accident is known as contaminants and the unwanted substance added to the food product to reduce the cost or to improve the other properties are known as adulterants. Contaminants and adulterants may lead to pathogens and toxins that pose serious concerns over the health of the consumer (Jha, 2016). The adulterants and contaminants are classified as physical adulterants and contaminants, chemical adulterants and residues, microbiological and pathogenic contaminants and toxins.

   Hazards in food can be categorized into physical, chemical and biological.

   Physical Hazards: Physical hazards are foreign organic or inorganic objects or extraneous materials in the food products. Hard and sharp physical hazards are of particular concern. Examples of physical hazards are broken glass, plastics, metal pieces, wood pieces, stones etc.

   Introduction

   For the year 2016-17, as per the FAO global estimate, the food grain production has crossed over 2.6 trillion metric tons, while the steadily increasing the demand is anticipated to be approximately 3.3 trillion metric tons for 2016-17. Similarly,the global production of all horticultural commodities has crossed over 1.8 trillion metric tons. The global trade of these commodities is purely based on their quality, the demand for good quality produces increases day by day. The term “quality” is a broad terminology used to explain many parameters and differs from commodity to commodity. Usually, the term ‘quality’ is classified into internal and external quality. The external quality refers the external colour, size, shape appearance, uniformity, external damage, cracks and bruishness etc. These parameters may be common for both perishables and durables.

   But, in case of internal quality, each and every parameter vary from commodity to commodity, product to product. For food grains, the internal quality refers to moisture content and other nutritional parameters like carbohydrate, protein content etc. But in fruits, the internal quality refers to internal pulp colour, TSS, pH, acidity, juice content, ripeness, other biochemical and nutritional quality parameters.

   The safety of the food supply suitably remains a high main concern for industry stakeholders, regulatory agencies and patrons. With the surfacing of new safety challenges and issues, companies are establishing and upgrading programs to reduce risk factors. These programs are constantly monitored for reliability, repeatability, reproducibility and effectiveness. Due to the health and safety risks posed by chemical, microbiological and environmental contaminants, analytical methods are progressively more becoming a pride and joy of food safety programs. Innovative analytical approaches are being developed in response to budding food safety issues. To monitor for known issues only the established and officially approved methods are used often. Oftentimes, new analytical methods are developed, improved or modified quickly in response to issues, such as melamine contamination, which are unforeseen. In such instances, accurate data derived from sound, validated analytical methods are required to facilitate industry stakeholders and regulators to make sound methodical decisions.

   Through research, industry has improved a host of analytical methods in recent years, resulting in higher sensitivity and accuracy for difficult-to-detect contaminants, detection of contaminants in new matrix classes for grades. These advances have been made in the face of changing set of laws, more painstaking method-validation standards and end user demands for safe, quality products. Further to this, this spirit of innovation will continue to be fundamental in industry’s efforts to ensure the safety of the comprehensive food chain.

   Introduction

   The food that we consume should not only contain all essential nutrients like carbohydrate, protein, fat, vitamins, minerals, fibre etc but also should be hygienic and safe. Safety and quality of food is to be ensured not only during food production but also should be continuously monitored till it reaches the consumer (Coles and Frewer, 2013). The characteristics of food are altered during every processing operations viz., cleaning, sorting, transportation, thermal processing, packaging, storage, distribution etc which may be desirable or undesirable. Persistent physical, chemical and microbiological analyses have to be done at all levels of supply chain to ensure the quality of food. Traditional methods of food safety analysis are spectrophotometry, aerobic plate count method, microscopic plate count, titrations, chromatography etc. Though these techniques provide accurate results, the analysis demand cumbersome extraction steps, trained technical staff and are time consuming (Di-Natale et al., 2000). Hence, steady, sensitive and rapid monitoring of food analysis technique is a need of the hour in the present era. Biosensors can effectively replace the conventional techniques owing to its reliability, rapidity, economic and field applicability (Prasad et al., 2014). Biosensors are an attractive diagnostic alternative owing to their in situ detection ability and comparatively reduced detection time from several days to hours, or even minutes (Ruiz et al., 2017). Rapid food analysis can also minimise spoilage, especially in freshly harvested agricultural commodities, such as fruits and vegetables, meat, fish etc. In addition, the portable detection devices provide in-situ detection capabilities without extensive training and assist in integrating real time analysis in food processing centres.

   Introduction

   The world does not function without mathematics. In our day-today life we come across many problems which are solved mathematically. The mathematical logical system follows “Yes” or “No”, “True” or “False”, “1” or “0” which are precise outputs for the precise inputs. There are several ambiguous or vague problems which cannot be given with accurate precise value with the conventional logical operators. Beyond this Boolean logic operator the logical system which mimics the human brain and gives precise solutions for the imprecise linguistic variables is the Fuzzy logic system. Fuzzy logic is a novel approach that intends to imitate human reasoning using calculations and operations with fuzzy systems and linguistic variables. The problems with vague imprecise data which we come across in our day today life cannot be solved by conventional binary logical method. The fuzzy logic solution spontaneously splits a complex problem into its component parts. This reduces the solution to its component parts. Compilers may re-assemble the code for effective execution on some target, but at the programmer level the problem is a number of simple tasks.

   Fuzzy sets theory was introduced by Zadehin the year 1965, and it allows uncertain phenomena to be treated mathematically.

   Introduction

   Food grains have been the key component of the human diet for thousands of years and have played a vital role in framing human civilization. Rice, wheat, and maize, and to a lesser extent, coarse grains are major staples, crucial to the daily endurance of billions of people around the world. Cereal grains are consumed by more than 50% of world population to meet daily calorie requirements. Most grains undergo a milling process that ideally removes the outer bran (pericarp) and germ layers; catering to consumer market requirements. To a farmer, yield is the most prominent aspect. As the grain moves along the supply chain, and as the product reaches the market, quality becomes the key determinant of its sale-ability and economic value. Grain quality is defined by a range of physical and compositional properties where threshold necessities are set according to end consumer use requirements. Most industries and consumer markets have become habituated over the years to demand grain with specific attributes. Where consumers are close to the source of grain production (e.g. in local markets), their own preferences and the laws of supply and demand control the grain quality. However, where grain is traded over large distances, particularly internationally, consumers almost have no direct influence on quality, requiring regulatory standards to be established and imposed to protect consumer rights. Therefore in the grain supply chain, all points have effects with respect to grain quality.

   Introduction

   Water is not only a vital environmental factor to all forms of life, but it has also a great role to play in socio-economic development of human population. Since antiquity humans have valued the importance of clean water and have used various techniques to improve its quality. In modern times, the safe drinking water became first a public health issue and then a human rights issue. The access to safe drinkin gwater now considered as a basic human right which is an essential component of effective policy for health protection. Improving access to safe drinking-water can result in tangible as well as intangible benefits to health. It has been shown that investments in water supply and sanitation can yield a net economic benefit, because the reductions in adverse health effects and healthcare costs outweigh the costs of undertaking the interventions (WHO, 2017). Past experiences have also proved that interventions in improving access to safe water favour the poor in particular, whether in rural or urban areas, and can be an effective part of poverty alleviation strategies. The disparity in water availability, reliability, and quality between the developed world and developing countries is enormous. Unfortunately, in many developing countries people lack access to safe water and therefore waterborne diseases are still a major cause of death, especially among children under age of 5. According to a joint report by World Health Organization (WHO) and United Nations International Children’s Emergency Fund (UNICEF) (WHO/UNICEF report 2017), around 2.1 billion people worldwide lack access to safe and readily available water at home, and around 4.5 billion, lack safely managed sanitation facilities. Moreover, many of these countries that have set drinking water standards often lack the resources to implement or enforce them.

   Introduction

   India, with its unique agro climatic conditions is capable of producing a wide variety of fruits and vegetables. These highly perishable produce in both fresh and processed forms are of high demand in domestic as well as international market. Nowadays farming is becoming an enterprise and shifting towards consumer driven agriculture. Produce quality measurement is of utmost importance as consumers are more quality conscious and ready to pay higher for quality. Consumer preference is moving towards healthy food, minimally processed and, fresh cut fruits and vegetables, prepared salads, ready to cook, ready to eat and ready to drink health beverages. Hence health, nutrition, convenience, quality and safety of produce should be guaranteed to the consumers. Due to globalisation of production and trade, legislations and standards for markets are strict and product quality is the necessity for competitive markets.

   Quality of a produce, based on subjective and objective measurement, is defined differently by consumers, wholesalers, retailers, processors or any other who is associated with it and varies with market either national or international. Quality of foods may be defined as the composite of those characteristics that differentiate individual units of a product, and have significance in determining the degree of acceptability of that unit to the user (Kramer, 1965). According to ISO (International Organisation of Standardisation), “Food quality is the totality of features and characteristics of a product that bear on its ability to satisfy stated or implied needs” and as per CAC (2003), “Food safety is the assurance that food will not cause harm to the consumer when it is prepared and/or consumed according to its intended use”. Food safety is the most important component of quality.

    Introduction

    Tropical tuber crops viz., cassava (Manihot esculenta Crantz), sweet potato (Ipomoea batatas), taro (Colocasia esculenta), yams (Dioscorea sp.), Elephant foot yam (Amorphophallus paeoniifolius), arrowroot (Maranta arundinacea) etc., are the important sources of starch after cereals and are used as staple or supplementary food in many of the tropical and sub tropical countries. Being the crops with adaptability to wide range of soil, climate and environment of the tropics and sub tropics and requiring minimum agronomic input and care for growth, they can be very well fitted into the prevailing cropping systems. They are the most efficient converters of solar energy and have the ability to reserve energy in the form of carbohydrate in the bulky roots and hence tuber crops are also called as calorie density crops. Tuber crops, though branded as poor man’s crops in rural areas have considerable unrealized potential for processing into high end products for food, feed and industrial uses. They are generally consumed as vegetable after boiling it in water and eaten along with some spicy curry or by extracting starch or flour. Besides serving as an insurance crop during times of food scarcity, it can also function as an industrial raw material for a wide spectrum of products

    Introduction

    As the world population continues to grow, the global market for food products is expanding, together with an increased emphasis on food safety. Consumers have become more discerning in the type of foods they buy and how these foods affect their health and well being. Food safety is generally defined as the assurance that the food will not cause any harm to the consumer when it is prepared and/or eaten according to its intended use ( To achieve food safety, a management system has been developed which aims on preventing problems before they occur, rather than trying to detect failures through end product testing. It also places more responsibility for ensuring food safety on food manufacturers, who have to develop control and traceability of their products from ‘farm to plate’. The system requires the identification of specific hazards throughout the entire process of food production, concentrates on the points in the process that are critical to the safety of the product, and highlights measures for their control (Henson and Caswell, 1999).

    Introduction

    Over centuries, spices have been used as an important addendum for colour, flavour and preservation of foods. In addition, their medicinal and cosmetic utilities have been widely recognized (Purseglove et al., 1981; Srinivasan, 2005). All these benefits made them extremely desirable with an ever growing demand in the international market. India holds the title of the largest producer and exporter of spices with major share for pepper, capsicum, turmeric, ginger cardamom, seed spices, curry powders, spice oils and oleoresins. The other primary producers of spices includes China, Indonesia, Malaysia, Egypt, Turkey Brazil and Mexico while USA, Europe, Japan, East Asian and Middle East countries are their major importers.

    Spices are made from diverse plant parts viz. rhizomes, barks, leaves, fruits and seeds and hence its processing methods vary depending on the raw material. However, the basic unit operations namely harvest, pre-treatment, drying, cleaning, particle size reduction, packaging and microbial decontamination in sequence remains common for the production of most of the spices. Inappropriate conduct of basic unit operations often lead to high microbial load, aflatoxin contamination, losses of valuable compounds, change in sensory characteristics, physical damages and incorporation of contaminants in spice products (Table 1). Moreover, spices being natural products, they may be fraught with a large number of microorganisms including several pathogenic species of bacteria and fungus depending on the prevailing conditions in their cultivation areas. In addition, poor food sanitation awareness and practices in spice producing countries may worsen their microbiological safety. Although spices are nonperishable in nature due to their low moisture contents after drying, they may act as a source of microbial populations upon contact with moist food products with no further thermal treatment. The outbreak of ‘salmonellosis’ in Germany (1993) due to contaminated paprika and paprika-powdered potato chips is an example. The aforesaid disadvantages related to conventional spice production may confound their international trade unless desired objectives of food safety management schemes such as International Commission on Microbiological Specifications for Foods (ICMSF) are met. Moreover, international agencies have set standard to guarantee safe spices and augment business interests of their adherents. For example, both the European Spice Association (ESA, 2015) and American Spice Trade Association have set a maximum level of 1% w/w extraneous matter in spices (ASTA, 2017). These challenges associated with the conventional production system may be effectively addressed by preventive risk management strategy by which suitable control measures are enforced at earlier phases of food chain prior to consumption. The control measures must guarantee that the level of contamination has not exceeded the maximum permissible limit at every phase of spice production from farm to table.

    Introduction

    Milk, an integral component of our staple diet is nature's most ideal and complete food. There is a long history and tradition of high consumption of dairy products in India. Consumption pattern of dairy products in India is quite unique and is centred on traditional products; however, novel products are gradually gaining momentum in urban areas. Despite being the largest milk producing country in the world, India accounts for a negligible share in the worldwide dairy trade. Domestic demand for dairy products is showing an increasing trend and it is expected that demand-supply gap will further widen which might transform India being a net importer of dairy products. The domestic demand for dairy products is showing an increasing trend and it is expected that demand-supply gap will get further widened. India, world’s largest milk producer has enough scope for diversified value addition as this can definitely assure a better margin of profit. However, for this, one has to maintain reputation and competitiveness in the market. To emerge as a leader in this competitive global market, continuous improvement of quality is highly essential. Safety, just as the other side of the coin is also of utmost importance to reinforce consumer confidence. Nowadays, quality is not a matter of choice but a necessity and even a responsibility of all stake holders. In the case of food, the term, 'Quality' refers to physical, chemical, microbiological, technological, economic and aesthetic characteristics. From consumer point of view, the word, 'Quality' embraces mostly the organoleptic characteristics like body, texture and flavour than the objective properties like fat, protein, lactose and acidity as determined by science based tests.

    Introduction

    Humans have primarily consumed "meat/meat products based on where they lived and how they evolved. According to Food Safety and Standards Act 2006, “meat means fresh meat, poultry and game meat which could be in the form of whole pieces, cuts or comminuted (minced etc.), whereas, meat products are those that have been processed by various methods so that they no longer resemble fresh meat”. These products include meat, poultry, and game products in whole pieces or cuts that are cured salted and dried, processed by non-heat treatment, fermented non-heat treated products, heat treated or frozen products. Edible casings used for sausages etc. also come in the category of meat and meat products. Through a notification dated 12^th September, 2017, the FSSAI has included domestic rabbits (Oryctolagus cuniculus) in the Food Safety and Standards (Food Products Standards and Food Additives) Regulation 2011 in the regulation under meat and meat products.

    With the advent of globalisation, there has been an increase in food trade which has led to the introduction of exotic meat and meat products. Moreover, rapidly growing economies like India, now demonstrate a growing appetite for meat. As the consumer demand for high quality meat is increasing in most countries, the meat industry should consistently produce and supply quality meat that is safe and healthy for the consumer to ensure continued consumption of meat products.

    Introduction

    Meat derived from animals are subjected to various contaminations from number of sources. The animal itself is a major contributor of both pathogenic and spoilage organisms. Further contamination may be introduced from water used, equipment used for product preparation, from the meat handlers and the surrounding environment. Microbiological problems such as food poisoning or spoilage may arise when the desired effect is not achieved and is usually due to errors in the handling or processing procedures. The detection and rapid correction of such errors and their future prevention is a major objective of any quality control system.

    In traditional approach to meat and meat product quality control system, only the samples of the final product were analyzed by laboratory test to check for compliance with specifications. However, the responsibility for control of hazards rests with individuals involved in all stages from farm to ultimate consumer. And the control of hazards at each stages of food chain may be achieved by Hazard Analysis Critical control point (HACCP). Hazard analysis critical control point is an internationally recognized system that helps to ensure the manufacture of safe food products. HACCP is not a zero risk system but rather a system designated to minimize the risk of food safety hazards. HACCP concept is a systematic and rational approach Firstly by consideration of the hazards i.e., microorganisms or their toxins, that need to be controlled in a specific operation by structured hazard analysis and secondly on the identification of the most effective means of controlling the identified hazards. This system, by focusing attention on the factor that directly affects the microbiological safety and quality of meat foods, eliminates wasteful use of resources and superfluous consideration. As a consequence, the cost/benefit relationships are more favorable. The system is applicable at all levels of meat food chain from farm production through processing, transporting, merchandising and ultimate use in the meat food service establishment or at home. Ensuring food safety and quality is the responsibility of all links in the food chain. Now a day’s food consumers are very much health conscious and they want their food to be safe and of good quality. As meat being highly perishable and high risk food product, it is very much imperative on the part of meat and meat products producers and exporters to produce safe and quality meat to stand in the competitive world and further hygienic meat processing is important not only to provide safe and wholesome meat but to provide a good public image and to increase consumer demand.

    Introduction

    Food is an important contributor to human well being and is essential for sustaining life. From this point of view food is expected to contains essential nutrients, such as carbohydrates, protein fat, vitamins and other essential minerals which support life. The food production initially started for individual sustenance which slowly developed in to a community requirement necessitating the involvement of man and machinery for various activities concerned with food. The progress from famine in many parts of the world to the level of self-sufficiency and the role of science and agriculture have been absolutely significant in many parts of the world. India is no exception and the green revolution during the post 1960s and the succeeding blue and white revolution ensured the self-sufficiency in India.

    Of late food acts as a vehicle for inclusion of hazard in food meant for human consumption. According to Grunert (2005), factors responsible for the alarmingly higher rate of concern by public include significantly higher number of food scares in public domain, critical understanding of production and processing of certain food products sold in the market as well as the diversified food choices of the consumers in different parts of the world. Besides, the increased awareness of the consumers on food related health issues also have its share in the increased concern on food at large.

    Presently food is considered as a commodity which crosses international border concurrent with the human movement and hence quality has become a major concern. The traditional food is getting replaced with value added products, particularly ready to cook, ready to eat, partially cooked products, etc. consequent to life style changes. In order to meet the demand of the trade, the conventional processing is getting replaced by community processing or industrial processing with increased number of players in the primary production, processing, transportation and other value chain activities prompting larger product control. In the process, consumers are exposed to a variety of products produced as business ventures in modern food production systems needing efficient quality control and quality assurance to tackle the issues of quality. The increased incidence of hazards in both raw materials and final products consequent to the absence or inappropriate production schedule calls for increased food safety concerns. Besides the shelf-life of the products, addition of chemicals during the production also add to the concern.

    Wheat Production and Consumption

    Wheat, rice, maize, barley, sorghum and the millets are the main crops that provide nutrition to people worldwide. The production of grains in different countries depends on the various factors such as water availability, soil conditions, temperature, cultural and economical are most critical factors. Nutritional needs of the developing countries are more dependent on cereal grains compared to the developed ones. Approximately 60% of the calorie requirements in the developing countries are met from cereals. The International Grains Council (IGC) forecasted for total grains production in 2017-18 to 2.079 billion tonnes. There is a need to have major research to increase their productivity, reduce storage losses, enhance efficiency of processing and to ensure food safety in the entire supply chain. Among them, wheat is one of the most important crop species and is a staple food for about 35% of the world population. Wheat is unique among the grains because of its protein type, which when mixed with the water by mechanical forces yields into viscoelastic dough due to the formation of gluten. This unique property of dough is capable of retaining the gases which are produced by yeast or baking powder resulting in the production of an array of leavened products such as bread, cookie and cake.

    Wheat is also an important source of dietary proteins for humans but like other cereals, it is deficient in the essential amino acid lysine. Wheat crop is adaptable to the wide range of growth conditions compared to other major cereals and hence it is cultivated widely throughout the world. Wheat cereal is the major dominating staple in the North Africa, Central and West Asia, providing the 50% of the calorie requirement in the region. The world wheat production is 740 million tonnes, with China ranking first by producing 125 million tonnes of wheat annually. Other major wheat producing countries are India, USA, Russia Australia, France and Canada. The global per capita consumption of wheat is about 66 kg, which varies widely in different regions. In Algeria, Egypt, Israel and other Middle East as well as Eastern Europe the consumption of wheat flour is high (150 kg/year). The food uses of wheat in developing countries are more than 80%, while in developed countries it is less than 50%. The consumption of the wheat in developing countries is significantly increasing due to globalization and growing economies. After rice, wheat is a major cereal crop in India and contributes to more than 50% of the total calories. It is grown in the cooler regions of India during the period of November to April. In grain production, rice ranks first with the production of about 105 million tonnes per year. In India, total grain production is 136 million tonnes for the year 2016-17 as per the International Grains Council. India ranks second in the production of wheat in the world and produce about 95 million tonnes annually. The bread wheat (astevum) contributes to approximately 94% while durum wheat is 4% and dicoccum wheat accounts to 2%.

    Introduction

    Baking is a traditional activity which has a long history, and according to some recent discovery, it is indicated to be dated back to as early as around 21,000 B.C. It is termed as a complex operation of prolonged heat transfer through radiation, convection, and conduction. Baking is considered to be one of the oldest methods of cooking, most commonly the bread baking but it is not only limited to the bread instead it provides a wide range of products such as cookies, pastry, pizzas, breakfast cereals, etc. Baking includes lots of raw materials such as flour, water, yeast, milk and milk derivatives, shortening, sugars, eggs and some minor ingredients such as malt products, cocoa products, dough improvers, inhibitors of microbiological spoilers, spices, etc. Food items which are rich in sugar and carbohydrates such as chocolates, candies are known as confections, and the art of making these products is termed as confectionary. Confectionery can be broadly classified into two major categories, namely sweet confectionary and baked confectionery. Conventionally cake was defined as the flour based sweet food, whereas bread was defined as the flou-based non-sweet food.

    Baked confectionery, also known as flour confectionery includes products such as cakes, pastries, and similar baked goods, especially which are served in dessert. These delicacies hold history not much later to the bread baking. Earlier the baked confectionery especially cakes were only affordable by the rich and were prepared for special occasions such as festivity, celebrations, etc. but now a large number of flour confectioneries are being produced in the world which is delightfully acceptable and are much more in demand by a various group of people.

    Introduction

    Oils and fats are the major class of compounds in lipids. Oils and fats are essential nutrients in both human and animal diets and produced from plant, animal, marine and microbial sources. Dietary oils and fats are concentrated sources of metabolizable energy (9 kCal/gram) compared to protein or carbohydrates (4 kCal/g). According to the recommendations of Food and Agriculture Organization (FAO) of the United Nations, the maximum total fat intake for adults is 30 to 35% E (total energy calories). The minimum fat intake recommended is 15% E for most individuals and 20% E for women of reproductive age and for malnourished populations (FAO, 2010).The current dietary guidelines for optimal health and prevention of diet-related chronic diseases like diabetes, coronary heart disease (CHD), cancer and obesity emphasize the importance of both the quantity and quality of total fat in the diet. In addition to the caloric and nutritional value, oils and fats exhibit many functional properties in the diet. Oils and fats enhance the value of foods by releasing the flavours of other food components, provide texture, increase palatability of food, and impart the feeling of satiety after eating. Oils and fats provide essential fatty acids (omega 3 and 6) which are the building blocks for several metabolic pathways for the healthy life. Oils and fats are excellent carriers of fat-soluble vitamins A, D, E and K, and the absorption of these vitamins is impaired at very low-fat intakes. Due to this reason, sseveral countries have started using edible oils and fats as a suitable vehicle for the fortification of vitamin A and D as edible oils are consumed by almost everyone (Diosady and Krishnaswamy, 2018). Oils and fats are structural bodily components, and are involved in vital physiological processes, including growth, development, inflammation, and brain function. Lipoproteins are important cellular constituents, occurring both in the cell membrane and mitochondria, and also serving as the means of transporting lipids in the blood. Oils and fats are responsible for making biological membranes such as phospholipids and cholesterol, vital for making the cell membranes. Most of the edible oils contain several minor constituents which are known as potent nutraceutical constituents with several health benefits. In addition to edible purpose, oils and fats are being used in many industrial applications such as soaps, detergents, cosmetics, lubricants, specialty chemicals, biofuels, etc. Hence oils and fats are indispensable source for food (edible oils and nutraceuticals), fuel (biodiesel, lubricants etc.) and fabulous chemicals (oleochemicals).

    Introduction

    Food is any substance or a product obtained from nature, which contains nutritive and non-nutritive components that help to maintain or improve the health of an individual if consumed in optimal amount (Sukhneet and Malhotra, 2014). Globalization of food production and procurement makes food chains longer and more complex and increases the risk of food safety incidents. Infections and diseases arising from contaminated/adulterated food remain threats to global public health (Havelaar et al., 2015; Luo et al., 2019). The WHO reports shows that every year foodborne diseases cause the death of 33 million people including many children (WHO, 2019). Food safety is linked to the presence of foodborne hazards in food at the point of consumption. Since food safety hazards can occur at any stage in the food chain it is essential that adequate control be in place. Therefore, a combined effort of all parties in the food chain is required to deliver safe food products to the final consumer. Effective and harmonized food safety systems shall manage and ensure the safety and suitability of food in each link of the supply chain.

    Although the food industry has the prime responsibility of ensuring safe foods in most societies, the maintenance of a safe food supply is regarded as a responsibility of the government of that country. This responsibility has, over many years, led governments to adopt legislation, standards and regulations for food processing and to impose penalties when a business fails to meet the expectation. As with any legislation, an effective system for detecting failures to comply with the legal requirements increases compliance and hence, in this case, promotes food safety. Governments have an obligation to protect consumer health and this includes protection against food borne diseases. Food standards are therefore necessary to aid governments in protecting public health. However, the standards can only be effective when they are enforced through an efficient food control system. This therefore requires comprehensive legislation inspection, food monitoring and food borne surveillance. An efficient food control system must be supported by competent staff with good laboratory services. Political and institutional support and stability are also important elements.
