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

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

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

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

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

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

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

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

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.

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

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. 

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.

12.0. Introduction

The benefits of food laws to the consumers and the processing industries depend upon the efficacy with which the laws are implemented. The implementation of laws requires not only a well organized national infrastructure for inspection and quality control, but also requires reliable methods of analysis, that can be used to check the quality standards for improvement of the food product w.r.t. nutrition, safety and sensory attributes. Early and accurate analysis of food product prior to preservation, during preservation or post preservation is a crucial component for quality evaluation and their quality control. Quality control in food industries depends upon three principles viz. i) raw material control, ii) process control and iii) finished product inspection. Once a product has gone through the manufacturing process, little can be done to alter its quality or to overcome the faults. Examination of the finished product at the most represents analysis with respect to standards – to accept or reject. Effective control over the raw material and process minimizes the rejection of the products. The food spoilage can be managed most effectively, if control measures are introduced at an early stage of food preparation/contamination. Reliance on symptom is often not adequate because spoilage may occur before symptom appears. The spoilage of the food may affect sensory, physical, chemical or microbiological attributes. Therefore, now a day, food processors want to analyze their food samples quickly without any delay in shipment for which they have to depend on the different methods for their quality evaluation. The analysis and quality control of food products involve physical, chemical, microbiological and sensory methods. So, widely used standard procedures / methods for evaluation of quality of food prior to preservation, during preservation or post preservation has been given in this chapter for easy implementation.

11.0. Introduction

Agricultural marketing is one of the important branches of agricultural economics. Farmers have one commodity or the other in surplus and need to be disposed off or sold to earn some money to satisfy other needs, which otherwise cannot be satisfied on the farm or in the village. Thus, agricultural marketing has two-fold objective i.e. Sale of surplus commodities and buy other commodities to satisfy family needs. In modern commercial agriculture, the surpluses with farmers are steadily rising, so also their family needs are changing with the change in lifestyle. Therefore, agricultural marketing has assumed important place. Traditionally, market is place or building where buying or selling of goods takes place. But, in modern times with fast and long distance communication facilities like telephone, market is no more restricted to a particular place only, but it has become wider and has assumed regional, national or even international status. Buying and selling is finalized on telephones only from distant places. Thus, the concept of market has radically changed.

So, marketing of food/ processed food is an important and vital constituent of modern business management. Knowledge about market is critical for the success of the product in such a highly competitive global market place. Now a day, in such modern time, marketing is itself a highly specialized and distinctive discipline. Based on marketing rules and laws, marketing is sometimes regarded as marketing science. Modern marketing strategies, tools and techniques have attained such complexity that marketing is linked with those of the modern warfare. The results of the marketing wars are witness by Cola wars and other brand bars being fiercely fought in the global market. So, the markets have become virtual battlefield for the brand wars. Markets and technologies are the two powerful forces driving the food processing industry. Further packaging has become a powerful tool in the promotion and marketing of the processed food products.

10.0. Introduction

Food processing is an important sector in agriculture, the scope of which has increased manifold that can help to prevent wastage of perishable commodities to a great extent. But, at the same time, food processing industries generate a large quantity and variety of food products, provide employment to a large number of people and uplift their economic status. The production, processing and preparation of food, all results in generation of huge quantity of waste material causing health hazards due to environmental pollution. The waste material may be in the form of leaf/ straw, waste during harvesting, food preparation waste, after processing waste, unused material as waste, food processing operation waste etc. The huge wastage of the food material is due to lack of control on such agri-economy practices. So, the disposal of waste material has become a challenge to the processors, as different agencies are pressurizing for an environment friendly treatment of waste material. The utilization of waste for the production of value added products is very important in the management of food processing waste. Different types of food industries wastes are: i) fermentation industry waste, ii) fruit and vegetable industry waste (Table 10.1) iii) Sugar and starch industry waste, iv) diary industry waste, v) meat processing industry waste, vi) coffee industry waste and vii) palm oil industry waste, viii) fish processing industry waste. So, there is great need to find out options which have positive values of food waste. The options having positive values are: i) minimization of the waste generation, ii) development of value added products. Most of fruit and vegetable wastes are a rich source of vital constituents like carbohydrates, proteins, fats, minerals, fibres etc. Mango seed kernel is rich in carbohydrates, fats, proteins, minerals; orange, melon and pumpkin seeds can provide fats and mineral matters. Apricot kernels are rich source of oil (45%) and proteins.

Enzymes are organic biocatalysts which initiate and control biological reactions. A catalyst is an agent affecting the velocity of a chemical reaction without appearing among the final products of the reaction. Unlike general catalysts, enzymes are specific in nature and function at a temperature of approximately 37^o C and pH close to neutrality. All enzymes are proteins but all proteins are not enzymes. These are distributed among the cell and tissues of plants and animals. Use of malted barley in brewing, yeast in the production of alcoholic beverages and wrapping of meat in the bruised leaves of papaya tree for tenderizing meat are techniques that have been used for centuries. In bread and cheese making also, enzymes have been exploited from generation to generation. Thus, enzymes have been used without knowing the nature of enzyme as catalysts and reactions involved. However, it is only recently that nature and action of enzyme is known and its importance in food industry is realized.

8.0. Introduction

Food additives are the substances not normally consumed as a food by itself and contain or not contain nutritive value but are added to food to improve freshness, sensory and keeping quality of food. So, a food additive is defined as a substance or a mixture of substances other than the food stuff incorporated in food either directly or indirectly as a result of any phase of production, processing, storage or packaging to improve or maintain the nutritional value, enhance quality, consumer acceptability and facilitate the preparation of materials e.g., acid, alkali, bleaching agents, emulsifying & sterilizing agents, flavours, colours, nutrient supplements, clarifying agents, humectants, chemical preservatives etc. Every food available in the market or at home contains food additives. So, now the question arises that whether additives are safe from consumption/toxicological point of view or not? What are the facts or fictions, if additives are to be used in the food preparation? These are the most important questions to be answered and discussed before their use in food industry.

7.0. Introduction

The food safety is one of the most important of assurance system required for global expansion of trade between developed and developing countries. Assurance that food will not cause harm to the consumer when it is prepared and/or eaten according to its intended use is known as food safety concept. It is set of conditions and measures taken during the food chain like production, processing, storage and distribution in order to ensure that, the product consumption does not represent a risk to the human health.

6.0. Introduction

Food is the basic need of all living organisms and hence, its quality should be given top priority. Food processing involves number of unit operations for material handling and there are always chances that the food may be contaminated or adulterated. The food is said to be contaminated if food is injurious to health and contain filthy, putrid rotten odour of insect pests etc. and can affect a large number of the populations at a time and hazards may occur. However, a food is said to be adulterated if it contains any other substance which affects the nature and quality product or substance is substituted with cheaper substance. So, it is essential to set the minimum limits of the desirable characteristics required and the maximum limits of the undesirable components that the food should contain. This helps to set common standards for commodities and to prevent confusion among the consumers.

5.0. Introduction

Quality control is generally defined as the regulation by law of food manufacture, distribution and sale in order to prevent health hazards and fraud to the consumers. Thus, it becomes a criminal offence to sell adulterated, filthy or contaminated foods. Quality control is the scientific control of production. There are certain basic fundamentals which are required for successful running of the food processing industry. So, for successful quality control in an industry / organization certain management systems are needed. Depending upon consumer requirement and satisfaction, quality management system is based on four important pillars like management responsibility, resource management, product / service realization and measurement, analysis & improvement. This management system is also important for ISO certification in an organization / industry.

4.0. Introduction

Quality is a measure of the degree of excellence or degree of acceptability by the consumer. By quality, one can differentiate the individual unit of a product from the other units and can determined the degree of acceptability of the individual unit by the consumer. The quality may also be defined in term of end use and may vary depending upon consumer’s perception and need. According to USDA Marketing Workshop Report (1951) “quality is the combination of attributes or characteristics of a product that have significance in determining the degree of acceptability of the product to the user”. For industry, quality is a measure of purity, strength, flavour, colour, size, maturity, workmanship and conditions or any other distinctive attributes of the product.

According to Code of Federal Regulations “Quality is the inherent properties of any processed product which determine the relative degree of excellence of such product and includes the effect of preparation and processing and may or may not include the effects of packaging or added ingredients/ additives”.

3.0. Introduction

A hazard is any factor that may be present in the food or food products and can cause harm to the consumer either through injury or illness. Hazards may be biological, chemical and physical. It may be a biological, chemical or physical property or condition of food with the potential to cause an adverse health effect. Therefore, these hazards can be grouped into three broad categories (Fig 3.1). Further, various stages during which processing hazard can takes place in a food industry is illustrated through Fig. 3.2. Effect of different potential hazards on human health along with symptoms is presented in Annexure IV.

2.0. Introduction

Before dealing with the various processes involved in the processing of fruit and vegetables or any food commodity on commercial scale, it is necessary to consider certain important factors such as investment, site, building, water supply, staff, labour etc. which are essential for the successful running of the food processing plant. Processing plant is the premises, buildings, structure and equipment used in the preparation, processing, handling, transportation and storage of any food commodity / fruits and vegetables / the processed products. The design and layout of the food processing plant is of great importance, besides other important factors. The food processing plant may be single storeyed or multi-storeyed depending upon capacity of production and viability of the plant e.g. if the production of the plant is assumed to be small and processing plant have to run only for short duration during the year then single storeyed processing plant can serve the purpose. Plant layout, product layout and process layout are the most important components for setting up of food processing industry and can determine the working efficiency of unit. Sanitary requirements in food processing plant are also important for marketing of the prepared product in national and international market. Sanitary requirement is as important in food processing plant as is the treatment of the effluent waste. For setting up of the food processing plant certain guidelines have been laid out by FPO, 1955.

1.0. Introduction

Any commodity, produce or harvest in organic or inorganic form to be fit to eat by a particular society, and contributes materially towards growth and repair of tissue is known as food. Food processing is application of techniques in a systematic manner for preventing losses through preservation, processing, packaging, storage and distribution to ensure greater availability of a wide variety of foods. It is a set of methods and techniques used to transform raw ingredients into food for consumption by humans or animals.

The early stages of food processing were largely confined to primary processing of food crops, commodities and produce whereby all these rendered fit for consumption or sale in the markets. Processing of rice and oil seeds were the necessities of that time for living. Later on, World War II gave a fillip to some of other food processing industries to meet the demand of the defence forces of the country. Fruits and vegetables processing; wheat and sugar milling drew support and sustenance from the exigencies created by war. Post war situation almost merged into the post-independence scenario. However, food processing industry received its first major impulse after independence. During this time, all the primary food processing industries received top most priority and all necessary support from the Governments in the country.

Abstract

Agriculture is the major sector for the livelihood of the billions of people worldwide. Increasing population and decreasing arable lands are the major concern for the fulfillment of the desired food production. After green revolution more production in the crop is obtained by worldwide. Several insects and pests are responsible for the inhibition of desired production in agriculture. Therefore, pesticides play a major role in the control of destructive insects and pests. After ban of organochlorine pesticides, organophosphorus pesticides has been used vigorously. Beside the effective pest management in agriculture, residual organophosphorus pesticides are more lethal for human and other living creature. Monitoring of these compounds is very much essential in the food and agricultural samples. Chromatographic techniques are well adopted techniques for the hundreds of residual pesticides. Introduction of various analyzers in chromatographic techniques improve the monitoring of the residual pesticides from different samples. Therefore, recent advancement in residual pesticides isolation and chromatographic techniques has been discussed in this book chapter.

Abstract

We are very fortunate to be born in a nation which is blessed with awesome decent variety of natural products, fruits, vegetables, cereals, pulses and so forth. The population of India expanded consistentlythat cause a genuine sustenance and shelter problem. The supply of food is not adequate to fulfill the demand of the consumers. This shortage of food is the root for adulteration of foodstuffs by the traders. Food adulteration is a procedure in which the nature of sustenance is brought down either by the addition of inferior quality material or by extraction of valuable ingredient. An adulterant is a chemical substance which should not be contained within other substances (food, beverages) for legal or other reasons. The addition of adulterants is called adulteration. Food is adulterated to increase the quantity and make more profit. The food is sucked of its nutrients and the place where the food is grown is often contaminated. For instance: milkis mixed with water. Vanaspati is utilized as an adulterant for ghee. Adulteration of food is unsafe as it may be toxic and causes serious health hazards to the consumer. To evade this issue government has passed an act which is known as preservation of Food Adulteration Act. It covers security from risks involved due to contamination of poisonous elements. Instead of government efforts the informed and aware consumers will have the capacity to dispense with this issue. So, here in the chapter adulterants their types, effect on human health, laws and control measurement were reviewed and discussed.

Abstract

Consumers increased response to new products with high sensory, organoleptic and nutritional potentials has impelled a search for new substitutes to processing methods. For several years, thermal processing was the main technology for producing safe products with long shelf lives, although in most cases losses of fresh flavors, vitamins, and some physicochemical characteristics were the price of safety and long-term stability. Pulsed electric field (PEF) processing as a non- thermal technique has been proven to inactivate microorganisms with minimal losses of flavor and food quality, possibly making it the answer to present-day consumer demands. In addition, the low processing temperatures used in this non- thermal technology allow the process to be nutrient preserving, energy efficient, which translates into lower costs and fewer environmental impacts. In this chapter, the the configuration of various PEF equipment, their electric configuration and recent application of this technique in processing of foods have been discussed in detail.

Abstract

Ghee means the pure clarified fat derived solely from milk or curd or from desi (cooking) butter or from cream to which no coloring matter or preservative has been added. It is the second largest dairy product prepared from milk and it is almost 35% of total milk production. Unfortunately, the producers or the middle- men involved in the ghee trade, tend to adulterate ghee with cheaper oils and fats like vegetable oils, animal body fats, hydrogenated fats and sometimes even the non-edible mineral oils, especially during lean season to earn more money. Recently, the problem of adulteration has assumed a very serious dimension. Such a situation has tarnished the image of dairy industry. Methods presently adopted by food law enforcing agencies to ensure the quality of ghee are mainly based on the physico- chemical constants, but all these methods have some limitations. So researchers are always in search of different innovative methods to check the quality of ghee.

Abstract

Tremendous hike inworld population has increased thrust on the limited resources which has considerably affected the viability of the food. The emerging challenge for policy makers and food scientists is to put forward viable solutions. Utilization of underutilized crops/plants that act as good sources of starch could be explored in a better way for the sustenance of the limited sources like food crops/plants. The demand for starch and the foods containing starch has been increasing continually. Since, the starch in its native form has certain limitations in its functional properties to be used for different applications. Therefore, it becomes important to explore certain technologies which could be used for modification of starch. Among different technologies gamma irradiation ensures food safety while inducing physicochemical changes of the components. Although, the chemical modifications have been used widely so far but the concerns related to the chemical residues left are diminishing their demand. Hence, the physical processes particularly the gamma irradiation process has emerged as an efficient alternative with some benefits over other process like eco-friendly, economical, reliable and safe for altering the physico-chemical and biological characteristics of the product. Gamma Irradiation of starch has been successfully employed for the achievement of some desired physico-chemical, biological and functional properties of the foods and other related items. In this chapter, valuable impact of gamma irradiation on the physico-chemical, biological and functional properties of starch has been summarized.

To ensure safe food and adequate sanitation programs, the equipment used for processing of food products must be designed, fabricated, constructed, and installed according to sound hygienic design principles. This ensures the equipment can be adequately cleaned and sanitized, and that surfaces are resistant to daily exposure to corrosive food products and cleaning/sanitizing chemicals. This chapter focuses primarily on fundamental principles of hygienic design, which protect the product from microbial, chemical, and foreign-body contamination. This is followed by a discussion of general aspects of hygienic construction and design of food equipments, the selection of materials of construction and specification of surface finishes, fabrication, installation and cleaning and sanitization. Quality of raw materials or foods ingredients, proper processing, packaging and storage of finished products decides the quality of the food products. Planning for plant and equipment layout, its design, services (water, air, refrigeration, steam), waste disposal etc. are some of the critical factors, which contributes to quality. In addition, the food processing equipment must comply with strict standards and regulations, which are necessary for securing the quality and safety of the food products to the consumers.

Abstract

Micronutrient (vitamin and mineral) deficiencies affect more than 2 billion people worldwide and are especially prevalent in developing countries including India. Conditions due to vitamin mineral deficiencies account for 7.3 percent of the global disease burden.Iron deficiency (anemia), vitamin A and iodine deficiency disorders continue to be a grim public health problem. Thus, elimination of vitamin and mineral deficiencies is essential to improve the overall health of the masses as well as to sustain economic growth and national development. Food fortification is an effective intervention to deliver vitamin and mineral rich foods to large populations. In addition to the prevention of vitamin and mineral deficiencies, food fortification is an effective measure to raise vitamin and mineral levels by moving the population towards consuming recommended dietary allowances for most micronutrients-making it a long–term and a sustainable strategy. India is the largest producer of milk in the world with 146.3 million tonnes and the consumption rate of milk and milk products by all age groups of people are high.Therefore, fortification of milk with mineral and vitamins could be a safe and effective strategy to fight these micronutrient deficiencies.

Abstract

Nutrition and genetics both have very crucial role in human health and in development of chronic diseases such as cancer, osteoporosis, diabetes and cardiovascular diseases. Difference between individuals in response to dietary intervention is a well-known phenomenon in nutrition research (Ordovas, 2008).The effect of dietary changes on phenotypes such as blood cholesterol, body weight and blood pressure can differ significantly between individuals (Ordovas et al., 2007). Various bioprocess i.e. ingestion, absorption, digestion, transport, metabolism and excretion of nutrients and food bioactive components in human body is carried out through proteins such as enzymes, receptors, transporters, ion channels and hormones. Genetic variation leads to altered production and affect functional properties of these proteins. Furthermore nutritional efficacy is also different among different individuals which might be affected by nutritional status. Thus diet and gene expression are interrelated and have a mutual effect on physiology of human body.

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.

Abstract

Chitin has been ranked at second position after cellulose as the most abundant natural biopolymer. Chitin has similar chemical structure to that of cellulose with 2-acetamido-2-deoxy-b-d-glucose (NAG) monomers attached via ß (1–>4) linkages. Chitosan is the deacetylated (to varying degrees) form of chitin, which, unlike chitin, is soluble in acidic solutions. Therefore, Chitosan, a copolymer of glucosamine and N-acetyl glucosamine, is amongst the most copious biopolymers on earth and finds wide range of biomedical and industrial applications. It has been approved in 1983 by USDA as a feed additive. Chitin basically is obtained from prawn/crab shells and chemical treatment of chitin produces chitosan. Since supplies of seafood waste are seasonable and variable, so fungi can be used as alternative source for chitosan. The unique physicochemical properties of chitosan provide great potential of its utilization in food industry especially dairy industry such as production of dairy products, dairy waste water treatment, extension of shelf life of dairy products etc. In recent years, exotic synthetic compounds are losing their appeal, thus application of chitinous products in dairy as well as processing aids has received considerable attention. The modified chitosan with greater functional properties has increased application in different dairy foods. This chapter focuses on the fundamental uses of chitosan and their derivatives in a variety of dairy industry applications.

Abstract

Meat is considered to be a highly perishable food commodity because of its biological composition. Thus, to extend its shelf life and maintain its nutritive value, there is an urgent need to find out alternatives for synthetic anti-microbial and anti-oxidants. This will not only serve the purpose of meat product manufacturer’s but will also satisfy the consumers’ demand for minimally processed meat products devoid of synthetic preservatives. This review discusses the natural antimicrobial and anti- oxidants sources viz., various essential oils, their composition and application in different meat and meat products. Essential oils from basil, rosemary, thyme, oregano, ginger, basilica, balm, coriander, rosemary and clove have exhibited a better potential to be used as an antimicrobial agent in meat and meat products. They owe their anti-microbial properties to the phenolic compounds present in them. They dislocate cell membrane and disrupt functionality of bacterial cell membrane and eventually leading to the release of intracellular components. However, essential oils are not widely used due to the pungent and intense aroma imparted to the food, thus there is still need to work out on the novel technologies which can not only increase food shelf life but at the same time, are sensorially acceptable to the consumers.

Abstract

Agro-food industries generate a large amount of by-products and wastes. These byproducts and wastes have a negative impact in terms of the environmental concern due to the increase of pollutant disposal, and industrial sustainability because of high costs related to their management. These byproducts and wastes are rich in minerals, sugars and proteins. The composition and characteristics of wastes from different food processing industries vary and rely upon the production technique and the nature of the product. India is the second largest producer of rice/paddy in the world and the utilization of rice bran is gaining importance. However, a small fraction of these have been utilized. In case of fruits and vegetables, industrial processing of potato generates between 70 and 140 thousand tons of peels worldwide annually. Moreover, 37% of world’s total annual production of banana is shared by India. Hence, to minimize the disposal fees and trash collection new policies and methods have been developed for handling and treatment of wastes and byproducts. This chapter envisages the status of different agro-food industrial byproducts and wastes for the development of different food and non-food products.

Abstract

The interest in the utilization of industrial by-products is increasing day by day and is major reason for exploring different meat, poultry and fish industry waste and optimization of extracting conditions of different valuable compounds. Utilization of these by-products in effective manner can be positive for meat industry economy as well as environmental pollution of the country. Besides the potential revenue losses, non-utilized or underutilized by-products accounts for the extra cost for their disposal. Meat producers are converting these by-products into value added edible and inedible form. Among the most prominent current uses of meat, poultry and fish waste are food ingredients, water treatment, cosmetic and personal care products, biogas/biodiesel, biomedical and pharmaceutical application. Several studies have dealt with the production of several value-added products such as gelatin, collagen, enzymes, specific proteins, bioactive peptides, chitin, chitosan, and pigments fro m the meat industries waste. Recently, in the food and pharmaceutical industry, an increasing number of new applications have been found for products generated from meat, poultry and fish industry waste; in different products as foaming agents, emulsifiers, biodegradable film-forming materials, colloid stabilizers, and microencapsulating agents, in line with the growing trend to replace synthetic agents with more natural ones.

Abstract

India ranks in the world’s five largest producers of over 80% of agricultural produce items. Processing of agricultural produce generates substantial amount of crop residues which can have tremendous value to farmers. However, a large portion of the residues is burned on farm primarily to clear the field from straw and stubble; which affects the environment, soil health and crop yield.The conversion of crop residues to eco-friendly and valuable product like biochar is need of the hour. Biochar is an organic amendment which slowly releases C in the soil, and is stable over the years. Various applications of biochar like reduction in greenhouse gases emission, sequestering C in the soil, increasing crop yield, used as combusting fuel and livestock feedmakes it a promising candidate for sustainable agriculture and environment.

Abstract

Food lost during the production chain is referred to as postharvest loss. Reducing postharvest loss can effectively feed starving mouths while conserving resources and decreasing the pressure to produce more. There are five main areas where postharvest loss can be reduced – harvest, storage, transportation, processing, and retail. New approaches and technologies in each of these areas will increase the amount of food available for human consumption. The total loss due to poor post- harvest processing of agricultural products in India when valued in terms of monetary reflects a tremendous loss in the economy. Annual value of harvest and post-harvest losses of major agricultural produces at national level to be of the order of Rs. 92,651 Crore calculated using production data of 2012-13 at 2014 wholesale prices. Deficits in food items or financial loss should not have occurred if postharvest losses were reduced through proper processing and preservation from harvest to consumption. Both the government and private sector need to invest in research so as to improve and modernize post-harvest facilities for attaining more efficient market infrastructure and distribution channels. Research and extension activities have to be closely coordinated particularly in the public sector for the benefit of farmers, traders and consumers.

The dairy processing industry in India deals mainly with the fluid milk and/or short shelf life products, despite India being the largest producer of milk in the world, with an output bordering the 110 million ton mark. This feature offers immense potential in the area of R&D in dairy processing in terms of value addition. The potential gains are many, including higher returns for producers and advantages in terms of health, therapeutic, nutritional and/or gastronomy for the consumers. However, the Indian Dairy Industry can amass possible benefits by being a global contender in trade only when its products are at par with those available in the rest of the world in terms of price and quality. It is evident from the post-WTO scenario that for sustainability, Indian dairy industry will need to maintain wholehearted commitment to quality management right from the farm to the consumer, shedding its inhibitions and resistance to changes.

9.1. WTO Agreements and Food Industry

The General Agreement on Tariffs and Trade (GATT) was formed in 1947 and lasted until 1994, when it was replaced by the World Trade Organization (WTO) in 1995. The WTO is the only global international organization dealing with the rules of trade between nations. It provides a forum for negotiating agreements aimed at reducing obstacles to international trade and ensuring fair deal for all, thus contributing to economic growth and development. Currently, there are 16 agreements to which all WTO members are parties and two agreements to which only some WTO members are parties. WTO currently has 153 members, of which 117 are developing countries or separate customs territories. The Head Quarters of WTO is at Geneva (Switzerland) and the official languages are English, French and Spanish.

India has achieved a commendable position of being the highest milk producing country in the world. Nearly 110 million tons of milk per annum is contributed by small and marginal farmers having 2-3 milch animals which are scattered in lakhs of villages across the length and breath of India. The poor socio-economic conditions are serious constraints in producing raw milk of good quality. The quality of milk is further deteriorated during subsequent handling and transportation. Milk being a product of biological origin, is extremely vulnerable to attack by microbes. It is also a good vehicle for additives and adulterants without any apparent changes in its appearance. Thus, milk is susceptible to several post-secretion changes, some natural and some man-made.

Indian dairy industry faces a mammoth task to meet the world quality standards, particularly in the present context of globalization and increasing quality conscious consumers. In view of the highly perishable nature of milk soon after it is secreted, it is important to monitor its quality by having a firmly installed quality assurance programme along the entire production-to-supply chain. This can be possible with application of sensitive, accurate and rapid methodologies as a tool in quality assurance programmes.

Quality comprises of several attributes ranging from physical, chemical, technological and bacteriological through nutritional to aesthetic. All dairy plants have a quality assurance laboratory (Fig. 8.1) and usually follow chemical quality control with the intention of payments to contractors/producers, processing of milk and meeting mandatory requirements for end products. Quality is judged both by objective and subjective tests.

Cleaning and sanitisation are the two processes employed in dairy industry to ensure hygiene and product safety. The safety of milk and milk products is a very important aspect and every attempt should be made, during processing, to minimize contamination through handling and processing equipments. The accumulated dried milk solids (milk stones) consist largely of calcium phosphate, milk proteins (precipitated, coagulated and baked on by heat) and insoluble calcium salts from water and washing detergents. The surface can also contain biofilms, which are formed by the incorporation of bacteria into the accumulated inorganic and organic materials that attach to most surfaces. With time and in the presence of nutrients, a biofilm and the bacteria within the biofilm will grow and become strongly attached to the surface. The removal of dairy soil, milk stones as well biofilms is the prime objective of the cleaning process. International Dairy Federation (IDF) defines a clean surface as one which is free from residual film or soil that will not contaminate the food products coming in contact with it.

While cleaning refers to the removal of soil from the surface of the equipment, sanitisation implies destruction of all pathogenic and almost all non-pathogenic organisms. Cleaning and sanitisation are complimentary processes. Either of the processes alone will not achieve the desired result, which is to leave the surface as free as possible from soil and viable organisms. In actual practice cleaning and sanitisation overlap to some extent, as during cleaning a high proportion of bacteria are destroyed and others get removed in the detergent solution. Inadequate or faulty cleaning and sanitisation can have serious consequences, as milk is a prefect nutrient in which bacteria can multiply. A thorough understanding of the cleaning methods is, therefore, necessary for economic production of high quality food products.

Packaging is a tool that is used to contain the product, protect the product from environmental hazards and help in marketing the product. Examples of ideal natural packaging systems are that of a banana, orange, coconut and egg, where the packaging is provided by nature. The major step forward in the food processing arena has been the ability to protect and preserve products with packaging and hence ensuring the availability of fresh and processed products out of season and over long distances in various forms. Milk is a highly perishable product and is not uniformly available round the year to the whole country due to geographical and genetic variations. If dairy products are to be available all the year round the country, irrespective of the season and area, it must be presented in packages that are convenient to purchase and use.

Packaging has additional responsibilities of providing convenience, safety and facilitating, besides handling, storage and distribution of products. It should prevent spoilage of food by microbial or insect attack. It also preserves the quality and nutritive value of many foods by the exclusion of oxygen and the control of moisture loss or gain. It increases the shelf-life and ensures longer availability and contributes to the product image through structural and graphic design. Product information is also given out through the medium of labeling, which acts as a tool for marketing and advertising.

Milk, as secreted in the udder of a healthy animal is practically sterile, but during its transit to the processing plant, becomes heavily contaminated with a variety of micro-organisms. These may be responsible for spoilage of milk or for causing diseases in animals and human beings. It thus becomes imperative that adequate heat treatment is given to milk to destroy these micro-organisms, thus increasing the shelf-life of milk as well as making it safe. Varied heat treatments offer the potential of producing different kinds of processed milk to satisfy the needs of the consumer. To cater to the ever-increasing demand of consumers, several varieties of processed milk are available in the market, some of which are discussed below.

5.1. Pasteurised Milk

Pasteurisation was named after the renowned French scientist Louis Pasteur, who discovered that spoilage organisms could be inactivated in wine by applying heat at temperatures below its boiling point. The process was later applied to milk and remains the most important operation in the processing of milk.

It is the process by which every particle of milk is heated to such temperature-time combinations (usually to 63°C for not less than 30 minutes or to 72°C for not less than 15 seconds) and promptly cooled to 4°C or below so as to destroy any harmful bacteria that may be present without affecting flavour and food value. Pasteurisation does not involve the use of any additives. Apart from making milk safe to drink, pasteurisation increases the length of time it can be kept before it spoils. The nutrient losses due to pasteurisation are so small, that they are considered insignificant.

Milk, on reception at the dairy factory is subjected to various unit operations on its way to product manufacture. Processing is applied as a means to convert liquid milk into products or to render the milk (and products) safe from harmful organisms. The basic processing operations to which milk is subjected at processing units have been described in this chapter. The common processing operations employed are depicted in Fig. 4.1. Several of these operations are routine compulsory processes common to all dairies, while certain others are undertaken for specialized purposes in some dairies.

4.1. Filtration and Clarification

At the time of milking various foreign materials such as dirt, feed, manure, dandruff, hair, flies, dust particles, worn out cells, cell debris and many other undesirable substances may find their way into milk. The process of removal of this extraneous matter (solid particles of higher density than that of milk) is called filtration or clarification. This can be achieved either by simple filtration through specially woven filter cloth or continuous process of centrifugal clarification that helps

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.

Milk is the secretion of the mammary glands of animals. For human consumption, milk is that liquid obtained from the cow or the buffalo during the period following at least 72 hours after calving or until the milk is colostrums-free. It is a complex biological fluid consisting of seven main components: water, fat, protein, sugar (lactose), minerals, vitamins and enzymes. Milk is a white opaque fluid in which fat is present as an emulsion, protein and some mineral matters in colloidal suspension and lactose together with some minerals and soluble proteins in true solution. The opacity of milk is due to its content of suspended particles of fat, proteins and certain minerals. The colour varies from white to yellow depending on the carotene content of the fat. Skimmed milk is more transparent with a slightly bluish tinge. Milk of a good flavour has a pleasant, slightly sweet taste, and no odour. It is an excellent source of calcium, phosphorous and riboflavin. Vitamin A and D are currently added to whole milk, partly skimmed and skimmed milk.

1.1. Introduction

The significance of milk as the most wholesome single food available in nature has never been debated. It is as ancient as mankind itself, as it is the substance created to feed the mammalian infant. All species of mammals, from the lowly rat to the mighty whale, produce milk for this purpose. Several centuries ago, perhaps as early as 6000-8000 BC, ancient man learned to domesticate species of animals for obtaining their milk for consumption. These included cows, buffalos, sheep, goats and camels, all of which are still used in various parts of the world for the production of milk for human use (Fig. 1.1 & 1.2).

For looking into the biosafety in research laboratories, agriculture and other food producing industries it is important to look into the numerous strains of lactic acid bacteria that are associated with food systems and are capable of producing bacteriocin or antibacterial proteins with activity against foodborne pathogens such as Listeria monocytogens, Staphylococcus aureus and Clostridium botulinum. Recently considerable attention has been given on the identification of these proteins and their biochemical properties including spectrum of activity, production conditions, purification procedures, aminoacid composition and mode of action. Advances in genetic engineering have facilitated the characterization of proteins at genetic level, providing information about protein synthesis, structure and cloning of bacteriocin genes into other organism. One problem in the use of bacteriocin in their applications as bio-preservatives is the emergence of resistant population. The understanding on the mechanism of resistance to bacteriocins is limited which limits the application in biopreservation. Much of the work on bacteriocin has been done under controlled laboratory conditions without the presence of adventitious microbial population. More research is needed to determine the efficacy of bacteriocin producing organisms and bacteriocins which are stable under commercial conditions. Foodborne illness is a major international problem and an important cause of reduced economic growth. The contamination of the food supply with the pathogens and its persistence, growth, multiplication and/or toxin production

Food safety scientifically describes various methods of handling, preparation and storage of food to prevent any foodborne illnesses. However, it is important to check the safety between industry, market and the consumer. From the food industry to the market the practices relating to food labeling, food hygiene, food additives and pesticide residues are important to be looked into and the policies on biotechnology. The governmental imports and exports needs to be given proper guidelines. Certification systems and Inspection for foods need to be installed which should be clean and corruption free. When all this is properly considered the food could be safe in the market. This may allow for safe delivery and safe preparation of the food for the consumers. Many diseases are transmitted by food which serves as a growth medium for bacteria and cause food poisoning. In the developed countries it has been observed that there are many intricate standards for food preparation. However, in the developing countries the availability of adequate safe water itself is a question. It is possible to prevent food poisoning to 100%. An ordinance and code regulation in US (1943)was given.
