The material presented in this book deals with basic mechanisms of free radical reactions in autoxidation processes and anitoxidant suppression of autoxidation of foods, biochemical models and biologi cal systems. Autoxidation in foods and corresponding biological effects are usually approached separately although recent mechanistic developments in the biochemistry and free radical chemistry of per oxides and their precursors tend to bring these two fields closer. Apparent ability of antioxidants in diets to reduce the inci dence of cancer has resulted in scrutiny of autoxidized products and their precursors as possibly toxic, mutagenic and carcinogenic agents. Mechanisms of any of these effects have been barely ad dressed. Yet we know now that free radicals, as esoteric as they were only a few decades ago, are being discovered in foods, biochem ical and biological systems and do play a role in the above-mentioned causalities. The purpose of the Workshop and the resulting book was to give a unifying approach towards study of beneficial and deleterious effects of autoxidation, based on rigorous scientific considerations. It is our hope that the material presented in this book will not only provide a review of the "state of the art" of autoxidation and anti oxidants, but also reflect the interaction which occurred during the Workshop between workers using model sytems, and food and biological systems.

This volume results from the Eighth Basic Symposium held by the Institute of Food Technologists in Anaheim, California on June 8-9, 1984. The theme of the symposium was "Chemical Changes in Food during Processing." The speakers included a mix of individuals from academic institu tions, governmental agencies, and the food industry. Twenty speakers discussed topics ranging from the basic chemistry relating to food constituents to the more applied aspects of chemical changes in food components during food processing. It was the intent of the organizers to bring together a group of speakers who could address the chemistry of changes in food compo nents during processing from a mechanistic point of view. As a con sequence, the proceedings of this symposium emphasize the basic chemistry of changes in food constituents from a generic perspective which is intended to provide the reader with a background to address more specific problems that may arise.

Antioxidants are present naturally in virtually all food commodities, providing them with a valuable degree of protection against oxidative attack. When food commodities are subjected to processing, such natural antioxidants are often depleted, whether physically, from the nature of the process itself, or by chemical degradation. In conse quence, processed food products usually keep less well than do the commodities from which they originated. Ideally, food producers would like them to keep better. This objective can often be achieved by blending natural products rich in antioxidants with processed foods, or by using well recognised antioxidants as food additives. In order to understand their action, and hence to apply antioxidants intelligently in food product formulation, some knowledge of the mechanisms by which they function is necessary. This is complex and of antioxidative may rely on one or more of several alternative forms intervention. Accordingly, the various mechanisms that may be relevant are discussed in Chapter 1, in each case including the 'intervention' mechanism. When present in, or added to, foods antioxidants are functional in very small quantities, typically, perhaps, at levels of 0ยท01 % or less.

In this second edition, Edwin Frankel has updated and extended his now well-known book Lipid oxidation which has come to be regarded as the standard work on the subject since the publication of the first edition seven years previously. His main objective is to develop the background necessary for a better understanding of what factors should be considered, and what methods and lipid systems should be employed, to achieve suitable evaluation and control of lipid oxidation in complex foods and biological systems. The oxidation of unsaturated fatty acids is one of the most fundamental reactions in lipid chemistry. When unsaturated lipids are exposed to air, the complex, volatile oxidation compounds that are formed cause rancidity. This decreases the quality of foods that contain natural lipid components as well as foods in which oils are used as ingredients. Furthermore, products of lipid oxidation have been implicated in many vital biological reactions, and evidence has accumulated to show that free radicals and reactive oxygen species participate in tissue injuries and in degenerative disease. Although there have been many significant advances in this challenging field, many important problems remain unsolved. This second edition of Lipid oxidation follows the example of the first edition in offering a summary of the many unsolved problems that need further research. The need to understand lipid oxidation is greater than ever with the increased interest in long-chain polyunsaturated fatty acids, the reformulation of oils to avoid hydrogenation and trans fatty acids, and the enormous attention given to natural phenolic antioxidants, including flavonoids and other phytochemicals.

Seafoods are important sources of nutrients for humans. Proteins and non protein nitrogenous compounds play an important role in the nutritional value and sensory quality of seafoods. Consumption of fish and marine oils is also actively encouraged for the prevention and treatment of cardio vascular diseases and rheumatoid arthritis. Highly unsaturated long-chain omega-3 fatty acids are regarded as the active components of marine oils and seafood lipids. The basic chemical and biochemical properties of seafood proteins and lipids, in addition to flavour-active components, their microbiological safety and freshness quality, are important factors to be considered. A presentation of the state-of-the-art research results on seafoods with respect to their chemistry, processing technology and quality in one volume was made possible by cooperative efforts ofan international group of experts. Following a brief overview, the book is divided into three sections. In Part 1 (chapters 2 to 8) the chemistry of seafood components such as proteins, lipids, flavorants (together with their properties and nutritional significance) is discussed. Part 2 (chapters 9 to 13) describes the quality of seafoods with respect to their freshness, preservation, micro biological safety and sensory attributes. The final section of the book (chapters 14 to 16) summarizes further processing of raw material, underutilized species and processing discards for production of value added products.
