This reference describes recent advances and applications of capillary electrophoresis in the field of food science. The first two chapters are devoted to the fundamentals of capillary electrophoresis, and to the main sample preparation techniques used for food analysis using this miniaturized separation technique, respectively. These two introductory chapters are followed by several chapters focused on the different strategies for analyzing specific food components, including lipids, carbohydrates, proteins, peptides, amino acids, vitamins, polyphenols, and food additives. The information provided in these chapters helps readers to understand and develop appropriate methods to carry out a deep characterization of food samples. Relevant concepts such as food authentication, chemical food safety or the control of the quality and safety of dietary supplements, and food metabolomics are also covered, where appropriate. The big potential of capillary electrophoresis to achieve chiral separations and the determination of enantiomers in food samples or to develop targeted and non-targeted metabolomics strategies to ensure food safety and quality is also described. As an additional step towards analytical miniaturization, a chapter devoted to food analysis by microchip electrophoresis is also included in this book. All 14 chapters are contributed by highly experienced researchers in the field. Capillary Electrophoresis in Food Analysis is a key source of information for food chemists and analytical chemists in industry (quality control laboratories) and academia (research labs and training courses).

Carbohydrates and glycoconjugates play an important role in several life processes. The wide variety of carbohydrate species and their inherent polydispersity and heterogeneity require separation techniques of high resolving power and high selectivity such as high performance liquid chromatography (HPLC) and capillary electrophoresis (HPCE). In the last decade HPLC, and recently HPCE methods have been developed for the high resolution and reproducible quantitation of carbohydrates. Despite the importance of these two column separation technologies in the area of carbohydrates, no previous book describes specialized methods for the separation, purification and detection of carbohydrates and glycoconjugates by HPLC and HPCE. Therefore, the objective of the present book is to provide a comprehensive review of carbohydrate analysis by HPLC and HPCE by covering analytical and preparative separation techniques for all classes of carbohydrates including mono- and disaccharides; linear and cyclic oligosaccharides; branched heterooligosaccharides (e.g., glycans, plant-derived oligosaccharides); glycoconjugates (e.g., glycolipids, glycoproteins); carbohydrates in food and beverage; compositional carbohydrates of polysaccharides; carbohydrates in biomass degradation; etc. The book will be of interest to a wide audience, including analytical chemists and biochemists, carbohydrate, glycoprotein and glycolipid chemists, molecular biologists, biotechnologists, etc. It will also be a useful reference work for both the experienced analyst and the newcomer as well as for users of HPLC and HPCE, graduates and postdoctoral students.

Instrumental Methods in Food Analysis is aimed at graduate students in the science, technology and engineering of food and nutrition who have completed an advanced course in food analysis. The book is designed to fit in with one or more such courses, as it covers the whole range of methods applied to food analysis, including chromatographic techniques (HPLC and GC), spectroscopic techniques (AA and ICP), electroanalytical and electrophoresis techniques. No analysis can be made without appropriate sample preparation and in view of the present economic climate, the search for new ways to prepare samples is becoming increasingly important. Guided by the need for environmentally-friendly technologies, the editors chose two, relatively new techniques, the microwave-assisted processes (MAPTM (Chapter 10) and supercritical fluid extraction (Chapter 11). Features of this book: - is one the few academic books on food analysis specifically designed for a one semester or one year course -it contains updated information - the coverage gives a good balance between theory, and applications of techniques to various food commodities. The chapters are divided into two distinct sections: the first is a description of the basic theory regarding the technique and the second is dedicated to a description of examples to which the reader can relate in his/her daily work.

Over the last decade, high performance Capillary electrophoresis (HPCE) has emerged as a powerful and versatile separation technique that promises to rival high performance liquid chromatography when applied to the separation of both charged and neutral species. The high speed and high separation efficiency which can be attained using any of the various modes of HPCE has resulted in the increased use of the technique in a range of analytical environments. The procedures are, however, still in the early stages of development and several barriers remain to their adoption as the technique of choice for a range of analytical problems. One such barrier is the selection and optimization of the conditions required to achieve reproducible separations of analytes and it is in this area that this new book seeks to give assistance. The book is written by an international team of authors, drawn from both academic and industrial users, and the manufacturers of instruments. At its heart are a number of tables, divided into specific application areas. These give details of published separations of a wide range of archetypal analytes, the successful separation conditions and the matrix in which they were presented. These tables are based on separations reported since 1992 and are fully referenced to the original literature. The tables are supported by discussions of the problems that a particular area presents and the strategies and solutions adopted to overcome them. The general areas covered are biochemistry, pharmaceutical science, bioscience, ion analysis, food analysis and environmental science.

Food manufacturers, researchers and society in general are increasingly highly interested in the quality and origin of food products. Considering the complexity of the food chain in a globalized world — where many players are involved between production and consumption — fraudulent food manipulation and adulteration practices are increasingly easier to conduct without being detected. Generally, food adulteration is carried out to increase volume, to mask the presence of inferior quality components, and to replace authentic substances for the seller's economic gain. Analytical methodologies to guarantee food integrity and authenticity are therefore required.Chromatographic and Related Separation Techniques in Food Integrity and Authenticity — Volume A: Advances in Chromatographic Techniques addresses fraud prevention and the latest chromatographic and related separation analytical techniques to guarantee food integrity and authenticity by giving special attention to relevant authenticity issues in food production.Chromatographic and Related Separation Techniques in Food Integrity and Authenticity — Volume B: Relevant Applications addresses the relevant application of techniques to assess different food products' integrity and authenticity.

The first edition of Food Analysis: Theory and Practice was published in 1971 and was revised in 1978. The second edition was published in 1987, and in 1993 we found it necessary to prepare a third edition to reflect and cover the most recent advances in the field of food analysis. A complete revision of a book is an arduous and anguished task. The following are challenges that we wanted to address in this revision: to update the material without eliminating classic and time-preserved and honored methods used by the food analyst; to broaden and deepen the coverage and scope without increasing the size of the book; and to produce a textbook (for senior undergraduate and graduate students) with regard to objectives, scope, and outlay while providing a reference and resource for the worker and researcher in the field of food analysis. To meet those challenges we added much new material and took out practically the same amount of "rel atively outdated" material. Every chapter has been extensively updated and revised; many of the pictures in the previous editions were deleted and, whenever available and appropriate, were replaced by diagrams or flow sheets. In Part I we have expanded the seetions on sampling, preparation of sam pIes, reporting results, and reliability of analyses.
