This book offers a new physical chemistry perspective on the control of lipid oxidation reactions by antioxidants, and it further explores the application of several oxidation inhibition strategies on food and biological systems. Divided in 3 parts, the book reviews the latest methods to control lipid oxidation, it examines lipid oxidation and inhibition in different food systems, and it finishes with an overview of the biological, health and nutritional effects of lipid oxidation. Chapters from expert contributors cover topics such as the use of magnetic methods to monitor lipid and protein oxidation, the kinetics and mechanisms of lipid oxidation and antioxidant inhibition reactions, interfacial chemistry, oxidative stress and its impact in human health, nutritional, sensory and physiological aspects of lipid oxidation, and new applications of plant and marine antioxidants. While focused on lipid peroxidation in food and biological systems, the chemistry elucidated in this book is applicable also to toxicology, medicine, plant physiology and pathology, and cosmetic industry. The book will therefore appeal to researchers in the lipid oxidation field covering food, biological and medical areas.

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.

Lipid oxidation in food systems is one of the most important factors which affect food quality, nutrition, safety, color and consumers’ acceptance. The control of lipid oxidation remains an ongoing challenge as most foods constitute very complex matrices. Lipids are mostly incorporated as emulsions, and chemical reactions occur at various interfaces throughout the food matrix. Recently, incorporation of healthy lipids into food systems to deliver the desired nutrients is becoming more popular in the food industry. Many food ingredients contain a vast array of components, many of them unknown or constituting diverse or undefined molecular structures making the need in the food industry to develop effective approaches to mitigate lipid oxidation in food systems. This book provides recent perspectives aimed at a better understanding of lipid oxidation mechanisms and strategies to improve the oxidative stability of food systems. Five chapters on naturally-derived antioxidants that focus on applications within food systems Contributors include an international group of leading researchers from academic, industrial, and governmental entities Discusses the oxidative stability of enzymatically produced oils and fats Provides overviews on the complexities of lipid oxidation mechanisms, and emulsion systems most suseptible to rapid lipid oxidation

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.

Biochemistry of Foods attempts to emphasize the importance of biochemistry in the rapidly developing field of food science, and to provide a deeper understanding of those chemical changes occurring in foods. The development of acceptable fruits and vegetables on postharvest storage is dependent on critical biochemical transformations taking place within the plant organ. The chapters discuss how meat and fish similarly undergo postmortem chemical changes which affect their consumer acceptability. In addition to natural changes, those induced by processing or mechanical injury affect the quality of foods. Such changes can be controlled through an understanding of the chemical reactions involved, for instance, in enzymic and nonenzymic browning. Increased sophistication in food production has resulted in the widespread use of enzymes in food-processing operations. Some of the more important enzymes are discussed, with an emphasis on their role in the food industry. The final chapter is concerned with the biodeterioration of foods. The various microorganisms involved in the degradation of proteins, carbohydrates, oils, and fats are discussed, with special reference to the individual biochemical reactions responsible for food deterioration.

Designed to help all those who need to prevent or control oxidation, especially in food products, or to understand the properties of antioxidants in food, nutrition, health and medicine, this title covers chapters such as the chemistry of antioxidation, antioxidant action in multi-phase systems, antioxidants in biology, and among other topics. The field of antioxidants has expanded over the last six decades into a wide variety of multi-disciplinary areas that impact foods and health. Antioxidants in food and biology: Facts and fiction is a handbook designed to help all those who need to prevent or control oxidation, especially in food products, or to understand the properties of antioxidants in food, nutrition, health and medicine. It conveys the complexity of antioxidant chemistry by providing an appreciation of the various phenomena that affect oxidation and its inhibition in foods and biological systems. Beginning with the underlying chemistry, the book moves on to explain how the activity of antioxidants is affected at the interface of complex multiphase lipid systems and to discuss the problems of evaluating the activities of antioxidants in foods and biological systems. After reviewing the antioxidants present in various foods, the author addresses the hypothesis that the health of an individual is influenced by the efficiency of various protection systems against oxidant damage. He also considers whether or not additional or more effective natural antioxidants are needed in our diet to reduce oxidative stress from dietary and environmental factors, and to thus reduce the risk of cardiovascular disease.
