Food Contaminants

Chemical Contaminants and Residues in Food, Second Edition is an invaluable tool for all industrial and academic researchers involved with food safety, from industry professionals responsible for producing safe food, to chemical analysts involved in testing the final products. This updated edition is expanded to cover the latest research and emerging issues, and has additional information useful for food safety testing. Written by an international team of expert contributors, this edition explores the entire food chain, acting as a roadmap for further research. Includes expanded coverage on risk assessment and testing technologies Presents fully updated chapters to provide the most up-to-date information in research on food chemical safety Provides new information on hot topic areas, such as food additives, mycotoxins, nanomaterials and food contact materials

This book discusses different aspects of contamination in Indian food products. Particular attention is given to the presence and analytical detection of detrimental substances such as pesticides, mycotoxins and other biologically-produced toxins, food chemicals and additives with natural or industrial origin. Furthermore, the book addresses the production and the commercial exploitation of native botanical ingredients, and the question if such ingredients should be regarded as foods or drugs. It also sheds light on chemical aspects of organic farming practices in India. Readers will also find information on pesticides and other detrimental chemicals detection in Indian farming. The authors present a useful opinion on how and why food contaminants can lead to border rejections during export, in particular to the European Union.

This book contains contributions based on the proceedings of two symposia on food contamination held in London in April 1989 and May 1990, both of which were organised jointly by the Environment, Food Chemistry and Toxicology Groups of the Royal Society of Chemistry. The aim of these meetings was to assess the extraneous chemical contamination of food from two sources: firstly, food-chain contaminants - the presence of plant toxicants of fungal metabolites in food, or the contamination of food from environmental sources (airborne, aquatic and terrestrial); and secondly, food-production contaminants - contaminants of man-made origin brought about by a desire to facilitate food production and distribution. The contributors concentrate on the contamination of food by chemicals arising from environmental and food-production sources. Chapter 1 is concerned with food-chain contaminants present in food as natural components of the diet. This is followed by discussion of the chlorinated dioxins and furans, and polycyclic aromatic hydrocarbons. Following an introduction to the control and surveillance of food-production contaminants, four areas of activity are described: migration from food contact materials with particular reference to plastics, the analysis and regulatory control of veterinary products, the analysis of pesticides in drinking water and finally the problem of food taints.

How many times have we thought with concern about the possible contamination of food? Pollution, agricultural treatments, technological treatments, and packaging are the best-known human sources of toxic substances as food contaminants. The present book contains 11 original research papers representing various approaches of identifying and measuring toxic residues in food materials. The analytical determination of food contaminants is an indispensable tool in characterizing the adverse effects and unexpected toxicity related to food intake. No risk assessment would be possible without data from the analysis of food contaminants. This Special Issue is an interesting overview of recent methods and is highly representative of a broad worldwide outline, collecting authors from ten different countries and four continents. Very different toxics are described, from volatile organic compounds to heavy metals and from highly polar chemicals to classical organic contaminants. A wide range of analytical techniques are portrayed, including sample preparation and clean-up methodologies, classical chromatographic and hyphenated spectroscopies, and the latest high-resolution mass spectrometry applications. The presented works consider a varied selection of foods: the studied matrices are meat, fishery products, fruits, and miscellaneous beverages.

Food Contaminants and Residue Analysis treats different aspects of the analysis of contaminants and residues in food and highlights some current concerns facing this field. The content is initiated by an overview on food safety, the objectives and importance of determining contaminants and residues in food, and the problems and challenges associated to these analyses. This is followed by full details of relevant EU and USA regulations. Topics, such as conventional chromatographic methods, accommodating cleanup, and preparing substances for further instrumental analysis, are encompassed with new analytical techniques that have been developed, significantly, over the past few years, like solid phase microextraction, liquid chromatography-mass spectrometry, immunoassays, and biosensors. A wide range of toxic contaminants and residues, from pesticides to mycotoxins or dioxins are examined, including polychlorinated biphenyls, polycyclic aromatic hydrocarbons, N-nitrosamines, heterocyclic amines, acrylamide, semicarbazide, phthalates and food packing migrating substances. This book can be a practical resource that offers ideas on how to choose the most effective techniques for determining these compounds as well as on how to solve problems or to provide relevant information. Logically structured and with numerous examples, Food Contaminants and Residue Analysis will be valuable a reference and training guide for postgraduate students, as well as a practical tool for a wide range of experts: biologists, biochemists, microbiologists, food chemists, toxicologists, chemists, agronomists, hygienists, and everybody who needs to use the analytical techniques for evaluating food safety.

Provides Updated Approved Procedures For Detection And Estimation Of Toxic Chemical Food Contaminants, Their Origin And Mode Of Entry In The Foods And Feeds. Very Useful For Those Involved In The Manufacturing, Processing And Marketing Of Foods And Feeds.
