Book Description
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.

Book Description
During the last ten years, several new extraction techniques have been developed that are faster, more automated and use less organic solvents compared to classical solvent extraction techniques. Furthermore, there is a clear trend going towards the use of (and research on) environmentally sustainable methods, which is encouraging for the future. Supercritical fluid extraction (SFE) and pressurized liquid extraction (PLE) are two of the most useful techniques for extraction of non-polar and medium polar solutes from solid and semi-solid samples. These techniques commonly use pressurized carbon dioxide or hot liquids such as water as extraction solvents, respectively. For aqueous samples, stir-bar sorptive extraction (SBSE) has recently been developed. These are some of the techniques that will be described in the proposed symposium series book. Focus will be on the extraction of various compounds from food and agricultural samples in either an analytical or a process-scale point-of-view. Several of the book chapters will compare the different techniques, and describe their advantages and disadvantages. Applications discussed in this book include SFE of biopolymers from distillers dried grains, SFE of lipids from oilseeds, PLE of functional ingredients from plants and herbs, tandem SFE/PLE of acrylamide from potato chips, SFE and PLE of cholesterol and fat from hamster liver, and steam distillation-extraction (SDE) and SBSE of flavors from shitake mushrooms.
