In the course of the project COST 91 *, on the Effects of Thermal Processing and Distribution on the Quality and Nutritive Value of Food, it became clear that approved methods were needed for vitamin determination in food. An expert group on vitamins met in March 1981 to set the requirements which these methods must meet. On the basis of these requirements, methods were selected for vitamin A, ~-carotene, vitamin B1 (thiamine), vitamin C and vitamin E. Unfortunately, for vitamins B2 (riboflavin), B6 and D only tentative methods could be chosen, since the methods available only partially fulfilled the require ments set by the expert group. For niacin and folic acid some references only could be given because none of the existing methods satisfied these requirements, and for vitamin B , vitamin K, pantothenic acid and 12 biotin it was not considered possible to give even references. All methods were carefully described in detail so that every laboratory worker could use them without being an expert in vitamin assay. In October 1983 an enlarged expert group on vitamins approved the compilation of methods and approached a publishing house with a view to publication. The editors wish to thank Dr Peter Zeuthen, the leader of the project COST 91, for his interest in their work, and Mr G.

To achieve and maintain optimal health, it is essential that the vitamins in foods are present in sufficient quantity and are in a form that the body can assimilate. Vitamins in Foods: Analysis, Bioavailability, and Stability presents the latest information about vitamins and their analysis, bioavailability, and stability in foods. The contents of the book is divided into two parts to facilitate accessibility and understanding. Part I, Properties of Vitamins, discusses the effects of food processing on vitamin retention, the physiology of vitamin absorption, and the physiochemical properties of individual vitamins. Factors affecting vitamin bioavailability are also discussed in detail. The second part, Analysis of Vitamins, describes the principles of analytical methods and provides detailed methods for depicting individual vitamins in foods. Analytical topics of particular interest include the identification of problems associated with quantitatively extracting vitamins from the food matrix; assay techniques, including immunoassays, protein binding, microbiological, and biosensor assays; the presentation of high-performance liquid chromatography (HPLC) methodology illustrated in tables accompanied by step-by-step details of sample preparation; the explanation of representative separations (chromatograms) taken from original research papers are reproduced together with ultraviolet and florescence spectra of vitamins; the appraisal of various analytical approaches that are currently employed. Comprehensive andcomplete, Vitamins in Foods: Analysis, Bioavailability, and Stability is a must have resource for those who need the latest information on analytical methodology and factors affecting vitamin bioavailability and retention in foods.

Employing a uniform, easy-to-use format, Vitamin Analysis for the Health and Food Sciences, Second Edition provides the most current information on the methods of vitamin analysis applicable to foods, supplements, and pharmaceuticals. Highlighting the rapid advancement of vitamin assay methodology, this edition emphasizes the use of improved and sophisticated instrumentation including the recent applications and impact of the widely adopted LC-MS. Designed as a bench reference, this volume gives you the tools to make efficient and correct decisions regarding the appropriate analytical approach--saving time and effort in the lab. Each chapter is devoted to a particular vitamin and begins with a brief review of its uniqueness and its role in metabolism. The authors stress a thorough understanding of the chemistry of each compound in order to effectively analyze it and to this end provide the chemical structure and nomenclature of each vitamin, along with tabular information on spectral properties. They supply extensive insight into practical problem-solving including an awareness of the stability of vitamins and their extraction from different biological matrices. All information is heavily documented with the latest scientific papers and organized into easily read tables covering topics necessary for accurate analytical results. After presenting the chemistry and biochemistry of the vitamin, each chapter details the commonly used analytical and regulatory methods. A summary table gives at-a-glance information on many of these sources, as well as several of the AOAC International Methods. In addition the authors apply their extensive experience in the field to create a critical, interpretive review of the advanced methods of vitamin analysis with sufficient detail to be a valuable guide to cutting-edge methodology.
