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.

Antibiotic Resistance and Gene transfer
 
It is important that probiotic strains should be assessed for their phenotypical antibiotic resistance and potential to transfer resistance gene as otherwise they cannot be used in food (BgVV, 2000; Vankerckhoven et al., 2008). It is vital to do research on characterization of acquired resistance mechanisms and transferability of resistance genes and on methods for determining transferability.

SYNOPSIS

Animal source foods (ASF) include any food item that comes from an animal source such as meat, milk, fish, eggs, cheese and yogurt. Many individuals do not consume ASF or consume little ASF by either personal choice or necessity as ASF may not be accessible or available to these people. Animals are used as food either directly or indirectly by the products they produce. Animal source foods (ASF) include any food item that comes from an animal source such as meat, milk, fish, eggs, cheese and yogurt.

Abstract

By loosely inspiring the actions of neurons in the human brain, artificial neural networks (ANNs) are widely accepted as a powerful nonlinear adaptive approach to tackle complex, dynamic, highly nonlinear, and ill-defined problems in an increasing number of fields of food industry.They have been used extensively in food drying to solve problems of nonlinear function approximation, pattern recognition, data description, optimization, simulation, pattern recognition, control, data sorting, clustering, and noise reduction, due to their massively parallel structure and capability to learn from examples. In this chapter, after providing a brief description of ANN technology and its principles as well as the structure of the most commonly employed ANNs in this context, an example is given to explain how the ANN technique is used for modeling and controlling food drying process. Generally, modeling, prediction, and optimization of heat and mass transfer, thermodynamic performance indicators, and quality parameters as well as physico-chemical attributes of dried foods are the most popular subjects to attract researchers’ attention to apply the ANNs in food drying industry.

1. INTRODUCTION

Annuals are the group of plants that complete their life cycle in one season or in one year during which they grow, flower and produce seed; and after this they wither out. A true annual (like zinnia) is a plant that will grow from seeds, flower, produce seeds and die in one season. Zinnias provide a succession of flowers for summer colour in any sunny location with good soil drainage

The term annual when applied to herbaceous ornamentals refers to plants that are grown for only one season. A true annual completes its life cycle (bears seed) in one season and has an extended bloom span lasting (in most cases) throughout the summer. Some plants that we use like annuals in the garden actually are herbaceous perennial plants that bloom the first season but are unable to survive the winter climate.

Some varieties will self-sow or naturally reseed themselves. This may be undesirable in many flowers because the parents of this seed are unknown and hybrid characteristics get lost. Plants will scatter everywhere instead of growing in their designated spot. Examples: Alyssum, Petunias and Impatiens. Impatiens flowers are currently the most popular annuals and are unsurpassed for abundant flowers in a shady garden. Some perennials, which are plants that live from year to year are classed with annuals because they are not winter-hardy and must be set out every year. Examples are begonias and snapdragons.

Typically, the annuals we think are as loving the heat of summer, but there are some popular annual plants that prefer the cool of spring and fall. Examples: pansies, snapdragons, ornamental cabbage and kale. These plants actually grow more lush and vigorous when the weather is cool not hot and dry; therefore, they are often offered for sale in early spring.

Introduction
• Meat inspection involves proper veterinary examination of live food animals prior to slaughter (called ante-mortem examination), inspection of carcases and offals and pathological examinations where deemed fit
• Full ante-mortem inspection represents 50% of meat inspection
• Ante-mortem inspection is particularly useful for detecting scheduled or infectious diseases which are communicable to man e.g. anthrax, rabies and glanders
• Diseases where animals show nervous symptoms like tetanus, tuberculous meningitis, sturdy in sheep, lysteriosis, rabies, cysticosis etc. and where skin lesions are manifested such as food and mouth disease, swine fever etc. are easily detected during ante-mortem inspection which are difficult to be detected in post-mortem inspection
• Animals must undergo veterinary ante-mortem inspection on the day of their arrival at the slaughterhouse or before the beginning of daily slaughtering
The inspection must determine
1. Whether the animals are suffering from a disease which is communicableto man and to animals or whether they show symptoms
2. Whether they show symptoms of disease or of a disorder of their general condition which is likely to make their meat unfit for human consumption-- any medicine/substances
3. Whether they are tired, agitated or injured
4. Whether they are sufficiently clean to enter the normal slaughter protocol
• For public health purposes, the veterinarian must separate normal animals from those which may be suffering from a potentially zoonotic disease or present a hygiene risk to the slaughter hall environment owing to the soiled condition of their hide/fleece

1. Introduction Ayurvedic texts like Charak Samhita and Sushruta Samhita, have described millets as the staple food useful in managing diabetes mellitus (Sachan Kumar, 2004). Based on the experience of eating these millets for time immemorial, there exists also a strong traditional knowledge about health benefits associated with them. For example, as per an adage in the state of Karnataka, India: “Those who eat rice will grow as a light weight; their body being just like that of a bird; those who eat Jowar will become as strong as a wolf but those who eat Ragi (millets) will be the strongest of them all, plus they would be free from illness (‘nirogi’ in Sanskrit)”! Certain studies from literature refer nutraceutical character of millets, especially, Kodo and Kutki, which in our opinion should help mankind in eradicating malnutrition and hunger while ensuring sustainable supply of food.

Millets have immense potential of providing nutritional security worldwide and play a pivotal role in food and nutrition economy. The nutritional aspects of millets are comparatively superior from the widely consumed cereals across the globe. With the presence of various essential macro nutrients millets are also enriched with the goodness of micro nutrients as minerals, vitamins and possess various bioactive compounds that portray several health benefits. The nutritional attributes of the millets are accompanied with several antinutritional factors such as tannins, phytates, saponins, trypsin and amylase inhibitors etc. that limit the bioavailability of the essential nutrients and minerals in these wonder grains upon consumption.

In India, people are mostly vegetarian, depending largely on cereals and pulses, as their staple foods, which provide the main source of dietary proteins and calories. The proteins from pulses are known to be inferior quality, due to the deficiency of sulphur containing amino acids as well as due to other factors like digestibility, availability of amino acids, anti-nutritional factors, etc. The anti-nutritional factors present in this type of food, including their contents of enzyme inhibitors, lectins, flatulence factors, tannins, phytic acid and saponins. Anti-nutritional factors can cause detrimental effects to humans and animal growth and performance by impairing intake, uptake, or utilization of other food and feed components, or by causing discomfort and stress to humans and animals. The anti-nutritional factors mainly occur in pulses and grain legumes and foods and feed material prepared from grain legumes and pulses.

Substance which, from nutritional point of view, interferes with normal growth, reproduction or health when consumed regularly in amount existing in a normal component of diet should be considered as harmful and toxic. A significant part of human population relies on legumes as staple food for subsistence, particularly in combination with cereals. They are unique foods because their rich nutrient content including starch, protein, dietary fibre, oligosaccharides, phytochemicals (especially the isoflavones in soybean) and minerals. Their nutritional contents contribute to many health benefits to human.

Foods are classified into three groups on the basis of ease of spoilage. Spoilage meant a condition produced by the excessive growth of microorganisms leading gradually to decay or decomposition. The stable or non perishable foods like sugar, flour, grains and dry products do not ordinarily spoil unless handled carelessly. The semi-perishable food like potatoes, onions, apples, waxed fruits, fruits and vegetables having thick skin can be protected from spoilage if properly handled and processed. The perishable foods, like livestock products, seafood, and poultry items, dairy products, and most fruit and vegetables spoil readily unless special preservatives methods are used. The spoilage of foods may be caused by molds, yeast, bacteria, enzymes, food constituents and insects. The use of food additives have become necessary to prevent spoilage other wise caused by the growth of bacteria, yeasts and molds.

Food spoilage usually refers to undesirable changes occurring in food due to the action of micro-organisms, insects and enzymes. The original nutritional value, texture, flavour of the food are damaged, the food become harmful to people and unsuitable to eat. Today however, preservation has used such factors as temperature, water activity, pH, gases, organic acids, salts, antibiotics, irradiation, packaging and various combinations of these factors. Foods vary greatly in the length of time for which they can be held in their natural form without spoilage. Preservatives retard product spoilage caused by mold, air, bacteria, fungi or yeast. Bacterial contamination can cause food-borne illness, including life-threatening botulism.

Fisheries sector plays an important role in food security and fish is now traded internationally. Shift in the trading policies (import and export) of seafood/aquatic products are happening at a rapid pace and consumption of seafood increased globally in substantial quantum. It is estimated that aquatic products export from Asian countries outcompetes earlier contributions to their importing partners year after year. Aquatic products include chordates, mollusc and arthropods from freshwater, brackish and marine system. They are nutrient rich diet and perishable too in nature and this prompted the industry to process the seafood in to different forms such as frozen, canned, cured and dried to extend its shelf life and recently value addition step being followed to improve the customer satisfaction. Nevertheless, the risk associated with the transboundary exchange of pathogens of seafood importance and its antibiotic resistance cannot be disregarded. Majority of the pathogens are not a native flora of fish. Each step in the aquatic products production chain either in the captured or cultured fisheries involves the contact of the seafood to the environment where they are grown, various implements used, contact surfaces, handlers, water etc. This post harvest handling makes the seafood contaminated with the pathogens of seafood importance such as Escherichia coli, Salmonella spp, Clostridium botulinum, Listeria monocytogenes, Staphylococcus aureus, Vibrio cholerae, Vibrio parahaemolyticus, Shigella sp, Aeromonas hydrophila, Plesiomonas shigelloides and viral pathogens such as hepatitis A virus etc. Among these pathogens, Escherichia coli, Salmonella spp, Staphylococcus aureus and Shigella spp are non-indigenous to the aquatic environment and others are indigenous to the aquatic environment. Depending on the nature of the environment (contaminated water source), feeding habits (filter feeders), season of harvest (summer season) are very crucial factors which cause seafood inherently contaminated in nature.

Normally raw milk contains different levels of inhibitory substances, which restrict the normal development of bacteria and some times may even kill them. The degree of inhibitory activity varies considerably in milks of different species, viz, cow, buffalo, human. Maximum activity present in human milk, variations occur in the milks of individual animals and some times even at different milking or from different quarters of the udder of the same animal.
There are two groups of antimicrobial substances present in milk:
    1.    Inherent or naturally occurring substances in milk. 
    2.    Non- inherent compounds secreted into milk from other sources.

Abstract

The cereal grains are grown around the world, the most common is wheat, which accounts for one third of the total grain crop worldwide. In addition to providing energy, whole grains contain several key nutrients, including fibers, lipids, B vitamins and minerals as well as other beneficial components such as phenolic acids, flavonoids, lignans and phytosterols. Several of these components function as antioxidants. While multiple studies have been conducted to analyze antioxidants in different grains. In wheat and other grains, naturally occurring phytonutrients with antioxidant activity include phenolic acids, flavonoids, coumarins, polyphenols, phytates, terpenes, carotenoids, tocopherols and tocotrienols. Potential roles of the naturally occurring antioxidants in grains include free radical scavenger, reducing agent, complexation of prooxidant metals, quenchers of singlet-oxygen molecules and antioxidant defense enzyme system activators for biological systems. Wheat grain contains several components that have potential antioxidant activity and thus may have a protective role in human health. Traditional wheat-based breakfast foods include hot and cold ready-to-eat (RTE) cereals, as well as a variety of yeast-leavened and chemically leavened bakery products. Increasing baking time and temperature increases antioxidant activity in the bread crust and lowers antioxidant activity in the bread crumb portion. Wheat and wheat based products, particularly partial and 100% whole grain products have been shown to provide a variety of beneficial components including fiber, vitamins, minerals and other phytonutrients with antioxidant activity. Scientific evidence indicates that consumption of three or more ounce equivalents of whole grain foods per day may reduce the risk of coronary heart disease, type 2 diabetes and certain cancers and help with weight management.

Abstract

Dietary antioxidants can be found naturally in various fruits, vegetables and food products.Typically, antioxidant phytochemicals commonly found in food products are Vitamin C, Vitamin E, carotenoids, polyphenols, melanoidins and indoles. The main characteristic of an antioxidant is its ability to scavenge free radicals and form stable end product which inhibit the chain oxidative mechanisms that lead to degenerative diseases which are harmful to human health. Drying is widely used in food processing to minimize food wastage and to extend food shelf-life. Pretreatment, drying methods and storage conditions are some of the processing parameters affecting the quality of dried products. Selection of processing conditions and storage environment are therefore critical in maximizing the retention of food antioxidants. This chapter aims to compile and summarize studies carried out for antioxidants namely antioxidant contents in dried food products, effect of processing parameters and quantification methods in the analyses of antioxidants.

Aonla is said to be indigenous to tropical south-eastern Asia, particularly in central and southern India (Firminger, 1947). The genus comprises of about 350 species. It is also called Indian gooseberry, amla, nelli, myrobalan, amlaki, amali, ambala, amlika, sirikai, amalakamu in different regional languages in India. Aonla is one of the richest sources of natural ascorbic acid which is protected by high polyphenols content during storage and processing. Aonla is indigenous to central and southern India. It is found it Sri Lanka, Malaysia, China and Malacca. In India, it is widely cultivated in Uttar Pradesh, Tamil Nadu. Madhya Pradesh, Rajasthan, Gujarat, Chhatisgarh and Jharkhand.

Biosensors are the next generation detection devices, use biological sensing elements like enzymes, nucleic acids, antibody, cells, organelles, tissues, receptors; have got varied applications in the field of drug discovery, diagnosis, biomedicine, food safety and processing, environmental monitoring, defense and security etc. Microbial biosensors are analytical device that uses naturally occurring or engineered microbial cells as the recognition elements to detect physiological changes in cells with the help of suitable physicochemical transducer.

Pre-harvest factors are responsible for the majority of post-harvest losses. Fruits which have already been infected with insects and pathogens, have been poorly irrigated and fertilized, or are of low quality before harvesting will never benefit with post-harvest cures. As a result, the process of accomplishing production quality, as well as harvesting, processing, and selling, must be taken into account.
