Introducing the principles, practice and applications of mass spectrometric techniques in the study of natural substances in foods, this book conveys the depth and breadth of modern mass spectrometry in relation to food analysis. It covers traditional techniques such as electron and chemical ionisation and newer soft ionisation techniques such as matrix-assisted laser desorption ionisation and electrospray. All of these techniques are especially relevant in food quality and safety studies and in biopolymer analysis. The ability to analyse biopolymers by mass spectrometry is having a major impact on the study of food structure components, food proteins, food pathogens and food components produced from genetically modified organisms. The principles and practice of mass spectrometry are covered in the early chapters and are followed by applications in flavour analysis and the determination of non-nutrient, biologically-active, natural substances in foods. The analysis and metabolic studies of amino acids, peptides, proteins, lipids, sugars, carbohydrates and vitamins is also discussed, with separate chapters on mineral and micronutrient metabolism and techniques of pyrolysis mass spectrometry. Mass Spectrometry of Natural Substances in Food will be a valuable resource for food scientists, food analysts and others working in food research, nutrition and safety.

This book is designed as a laboratory manual of methods used for the preparation and extraction of organic chemical compounds from food sources. It offers ideas on how to facilitate progress towards the total automation of the assay, as well as proposing assays for unknowns by comparison with known methods. Beginning with an introduction to extraction methodology, Extraction of Organic Analytes from Foods then progresses through sample preparation, extraction techniques (partition, solvation, distillation, adsorption and diffusion) and applications. Subject indices for the applications are organised by commodity, method, chemical class and analyte, and provide useful examples of references from the literature to illustrate historical development of the techniques. Examples of methods that have been compared, combined or used in collaborative trials have been correlated and used to form the beginnings of a database that can be expanded and updated to provide a laboratory reference source. Logically structured and with numerous examples, Extraction of Organic Analytes from Foods will be invaluable to practising food analysts as both a reference and training guide. In addition, the introductory sections in each chapter have been written with food science and technology students in mind, making this an important title for academic libraries.
