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.

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.

High Oleic Oils: Development, Properties and Uses is the first complete reference to address practical applications for this new and dynamic category of fats and oils that are essentially replacing partially hydrogenated oils in various food and nonfood uses. As a category, high oleic oils are highly stable, but like other fats and oils, there are differences in the composition and applications of the various types of high oleic oils. Their compositions allow for the production of a range of frying oils, increased shelf-life foods, functional shortenings and hard fats, and even industrial products not easily produced with nonhigh oleic oils. Information and know-how on these applications and advantages has been in high demand and short supply until now.Based on extensive commercial experience, seminars and presentations, Editor Frank Flider has identified common customer questions, needs and concerns about high oleic oils, and addresses them in this single comprehensive volume outlining development, composition, and utilization of high oleic oils. Through the individual expertise of a highly qualified team of contributing authors, this book outlines the development, composition, and utilization of these oils, making it of value to a wide range of readers, including the research and development industry and academic researchers. - Details the development and technology behind today's high oleic crops and oils as well as the history and background of many naturally occurring oleic oils - Describes high oleic oils' nutritional and compositional advantages over PHOs and lower oleic oils - Presents unbiased, noncommercial, science-based, and objective insights, deliberately balanced to represent high oleic oil varieties equally - Addresses transgenic insights as well as new state-of-the-art and future development technologies
