Residue Analysis In Food

Residue analysis in food is an essential science in terms of the number of laboratories and analysts involved worldwide and the range of analytical techniques available. This text uniquely combines the principles and applications of the various techniques employed in residue analysis, so as to provide the reader with a thorough understanding and pr

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.

A practical handbook on the analysis of foods for pesticide residue contamination. Its ultimate aim is to assure that a food control laboratory produces high quality analytical results using analytical methodology which has been shown to be reliable and reproducible for pesticide residue analyses.

In the last decades the public concern on the pesticide residues content in foods have been steadily rising. The global development of food trade implies that aliments from everywhere in the world can reach the consumer`s table. Therefore, the identification of agricultural practices that employ different pesticides combinations and application rates to protect produce must be characterized, as they left residues that could be noxious to human health. However, the possible number of pesticides (and its metabolites of toxicological relevance) to be found in a specific commodity is almost 1500, and the time needed to analyze them one by one, makes this analytical strategy a unrealistic task. To overcome this problem, the concept of Multi Residue Methods (MRM) for the analysis of pesticide traces have been developed. The advent of new and highly sensitive instrumentation, based in hyphenatedchromatographic systems to coupled mass analyzers (XC (MS/MS) or MSn) permitted simultaneously the identification and the determination of up to hundreds of pesticide residues in a single chromatographic run. Multiresidue Methods for the Analysis of Pesticide Residues in Food presents the analytical procedures developed in the literature, as well as those currently employed in the most advanced laboratories that perform routinely Pesticide Residue Analysis in foods. In addition to these points, the regulations, guidelines and recommendations from the most important regulatory agencies of the world on the topic will be commented and contrasted.

The object of "Residue Reviews" is to provide concise, critical reviews of timely advances, philosophy, and significant areas of accomplished or needed endeavor in the total field of residues of pesticide and certain other chemicals in foods, feeds, and in transformed food products. During the 144th National Meetings of the American Chemical Society in Los Angeles, California the Pesticides Subdivision of the A.C.S. Division of Agricultural and Food Chemistry on April 1, 1963 sponsored a symposium "Instrumen tation for the Detection and Determination of Pesticides and Their Residues in Foods". With special permission from R.N. HADER and his associates in the American Chemical Society, that symposium is reproduced in this volume of "Residue Reviews" because of its time1iness and significance to pesticide residue analysts everywhere. Without exception the symposium authors accepted my invitation to utilize "Residue Reviews" as their publication medium, and their coopera tion in the extra chore of providing manuscripts conforming to the style requirements of "Residue Reviews" is gratefully acknowledged. Presiding over the two sessions of the symposium were CHARLES L. DUNN and MILTON S. SCHECHTER, whose introductory remarks at that time comprise the foreword to this volume; their enthusiastic assistance both in organizing the symposium and in achieving this final product is warmly a pprecia ted.
