DOWNLOAD EBOOKAntioxidants are an increasingly important ingredient in food processing. Their traditional role is, as their name suggests, in inhibiting the development of oxidative rancidity in fat-based foods, particularly meat and dairy products and fried foods. However, more recent research has suggested a new role in inhibiting cardiovascular disease and cancer. Antioxidants in Food: Practical Applications provides a review of the functional role of antioxidants and discusses how they can be effectively exploited by the food industry. The first part of the book looks at antioxidants and food stability with chapters on the development of oxidative rancidity in foods, methods for inhibiting oxidation, and ways of measuring antioxidant activity. Part 2 looks at antioxidants and health, including chapters on antioxidants and cardiovascular disease, their antitumour properties, and bioavailability. A major trend in the food industry, driven by consumer concerns, has been the shift from the use of synthetic to natural ingredients in food products. Part 3 looks at the range of natural antioxidants available to the food manufacturer. The final section of the book looks at how these natural antioxidants can be effectively exploited, covering such issues as regulation, preparation, antixoxidant processing functionality and their use in a range of food products from meat and dairy products, frying oils and fried products, to fruit and vegetables and cereal products.

DOWNLOAD EBOOKThe 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.

DOWNLOAD EBOOKWarmed-Over Flavor of Meat discusses related problems and issues on warmed-over flavor (WOF) of meat that contributes to a decrease in sale, meat consumption, and production expansion. WOF is old, stale, rancid, and painty flavor and odor of meat, apparently caused by the catalytic oxidation of unsaturated fatty acids. Comprised of 10 chapters, the book initially describes the mechanisms of metals’ role in the promotion of lipid oxidation. The text also discusses the content and distribution of iron in meat and the evidence concerning the ability of the various forms of iron in meat to promote oxidative degradation of lipids. The subsequent chapters describe the oxidative deterioration in muscle foods and the free radical processes pertinent to autoxidation of foods. A chapter presents evidence for and against heme catalysis of lipid oxidation and the antioxidant role of nitrite in cured meats. The book also considers sensory and instrumental analysis of volatiles and undesirable flavors related to WOF and the isolation and separation of heteroatomic compounds associated with beef flavor. The remaining chapters describe several methodologies for retarding or preventing WOF in meat, focusing on the practical procedure of the Maillard reaction. Lastly, sources of natural antioxidants for meat product preservation are considered. Food scientists, researchers, and manufacturers will find this book invaluable.
