The emerging field of green analytical chemistry is concerned with the development of analytical procedures that minimize consumption of hazardous reagents and solvents, and maximize safety for operators and the environment. In recent years there have been significant developments in methodological and technological tools to prevent and reduce the deleterious effects of analytical activities; key strategies include recycling, replacement, reduction and detoxification of reagents and solvents. The Handbook of Green Analytical Chemistry provides a comprehensive overview of the present state and recent developments in green chemical analysis. A series of detailed chapters, written by international specialists in the field, discuss the fundamental principles of green analytical chemistry and present a catalogue of tools for developing environmentally friendly analytical techniques. Topics covered include: Concepts: Fundamental principles, education, laboratory experiments and publication in green analytical chemistry. The Analytical Process: Green sampling techniques and sample preparation, direct analysis of samples, green methods for capillary electrophoresis, chromatography, atomic spectroscopy, solid phase molecular spectroscopy, derivative molecular spectroscopy and electroanalytical methods. Strategies: Energy saving, automation, miniaturization and photocatalytic treatment of laboratory wastes. Fields of Application: Green bioanalytical chemistry, biodiagnostics, environmental analysis and industrial analysis. This advanced handbook is a practical resource for experienced analytical chemists who are interested in implementing green approaches in their work.

In the 21st Century, processing food is no longer a simple or straightforward matter. Ongoing advances in manufacturing have placed new demands on the design and methodology of food processes. A highly interdisciplinary science, food process design draws upon the principles of chemical and mechanical engineering, microbiology, chemistry, nutrition and economics, and is of central importance to the food industry. Process design is the core of food engineering, and is concerned at its root with taking new concepts in food design and developing them through production and eventual consumption. Handbook of Food Process Design is a major new 2-volume work aimed at food engineers and the wider food industry. Comprising 46 original chapters written by a host of leading international food scientists, engineers, academics and systems specialists, the book has been developed to be the most comprehensive guide to food process design ever published. Starting from first principles, the book provides a complete account of food process designs, including heating and cooling, pasteurization, sterilization, refrigeration, drying, crystallization, extrusion, and separation. Mechanical operations including mixing, agitation, size reduction, extraction and leaching processes are fully documented. Novel process designs such as irradiation, high-pressure processing, ultrasound, ohmic heating and pulsed UV-light are also presented. Food packaging processes are considered, and chapters on food quality, safety and commercial imperatives portray the role process design in the broader context of food production and consumption.

Performing effective chemical separations-a step-by-step guide to the most commonly used techniques. How do experienced analysts go about making a chemical separation work? Through precise, detailed coverage of the principles, equipment, and techniques involved, this combination laboratory manual and reference source gives readers a working knowledge of an impressive array of separation methods. In forty-two chapters, it explores all major categories of separation, including those involving phase changes, extraction, chromatography, ion-exchange resins, electric fields, flotation, membranes, and miscellaneous techniques. With an emphasis on everyday practice rather than theory, Chemical Separations explains the principles and parameters of these methods with a minimum of mathematics, while providing 59 specific experiments to demonstrate proper procedures. Drawn from well-known commercial and academic laboratories and approved by national standard-setting organizations, these experiments feature step-by-step protocols for each separation scheme, precise instructions on setting up the apparatus, and helpful checklists for essential chemicals and supplies. With Chemical Separations as their guide, laboratory analysts and newcomers to chemical analysis will learn how to obtain quality analysis using commercial products, natural samples, and proven real-world laboratory techniques.

An insightful exploration of the key aspects concerning the chemical analysis of antibiotic residues in food The presence of excess residues from frequent antibiotic use in animals is not only illegal, but can pose serious health risks by contaminating products for human consumption such as meat and milk. Chemical Analysis of Antibiotic Residues in Food is a single-source reference for readers interested in the development of analytical methods for analyzing antibiotic residues in food. It covers themes that include quality assurance and quality control, antibiotic chemical properties, pharmacokinetics, metabolism, distribution, food safety regulations, and chemical analysis. In addition, the material presented includes background information valuable for understanding the choice of marker residue and target animal tissue to use for regulatory analysis. This comprehensive reference: Includes topics on general issues related to screening and confirmatory methods Presents updated information on food safety regulation based on routine screening and confirmatory methods, especially LC-MS Provides general guidance for method development, validation, and estimation of measurement uncertainty Chemical Analysis of Antibiotic Residues in Food is written and organized with a balance between practical use and theory to provide laboratories with a solid and reliable reference on antibiotic residue analysis. Thorough coverage elicits the latest scientific findings to assist the ongoing efforts toward refining analytical methods for producing safe foods of animal origin.

Almost two decades have passed since the first edition of Food Science was published in 1968. Previous editions have been widely circulated in the United States and abroad and have been accepted as a textbook in many colleges and universities. The book also has been translated into Japanese and Spanish. This response has encouraged me to adhere to prior objectives in preparing this fourth edition. The book continues to be aimed primarily at those with no previous instruction in food sci ence. Its purpose is to introduce and to survey the complex and fasci nating interrelationships between the properties of food materials and the changing methods of handling and manufacturing them into an al most unlimited number of useful products. The book especially ad dresses the needs for insight and appreciation of the broad scope of food science by students considering this field as a profession, as well as those by professionals in allied fields that service or interface with the food industry in ever-increasing ways. The literature of food science and food technology has rapidly ma tured from earlier articles to books to encyclopedias. Where technolog ical capabilities once were limited, rapid advances in many fields contin ually raise questions on the responsible management of technology and its environmental, social, and economic consequences. Changes in em phasis have been many. Affluent countries have become more con cerned with the health effects of nutrient excesses than with deficien cies, while hungry nations continue to suffer shortages.
