Book excerpt: 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.

Book excerpt: 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

Download or read book Advances in NMR Spectroscopy for Lipid Oxidation Assessment written by Hong-Sik Hwang and published by Springer. This book was released on 2017-02-16 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Brief provides a comprehensive overview of NMR spectroscopy, covering techniques such as 1H, 13C, and 31P NMR, which are reliable tools to determine lipid oxidation level, to identify oxidation products, and to elucidate oxidation mechanism. The Brief shows that 1H NMR spectroscopy continually demonstrates reliability, accuracy, convenience, and advantages over conventional analytical methods in determination of the level of oxidation of edible oil during frying and storage through monitoring changes in several proton signals of oil, including olefinic, bisallylic and allylic protons. This modern analytical method is shown within this text to be used to identify oxidation products, including primary oxidation products such as hydroperoxides and conjugated dienes and secondary products such as aldehydes, ketones, epoxides and their derivatives. By identifying intermediates and final oxidation products, many oxidation mechanisms could be elucidated. A relatively newer method, the text demonstrates that 13C NMR and 31P NMR spectroscopy can also provide additional information on the molecular structure of an oxidation product. Backgrounds, principles, and advantages over conventional methods, most recent advances, and future prospects of these methods are discussed. Advances in NMR Spectroscopy for Lipid Oxidation Assessment begins by covering the various mechanisms of lipid oxidation, including various methods to determine oxidation products. NMR spectroscopy is then covered, including its applications in foods. The next section focuses on 1H NMR Spectroscopy, including its use for assessment of lipid oxidation during oil storage and frying. The following section focuses on 13C NMR spectroscopy, including its use in determining and identifying oxidation products and mechanisms. A final section focuses on sup31“/p>

Available in PDF, EPUB and Kindle. Book excerpt: Oxidative modification of lipids and phospholipids—including radical damage, halogenation, and nitration—result in significant changes to the chemical properties of the molecules, which in turn have a major effect on their biochemical functions. Lipid oxidation has long been regarded as a deleterious process responsible for lipid rancidity, loss of function, and generation of toxic products. However in recent years, research has also focused on the non-detrimental physiological and pathological effects of these chemical reactions. Lipid Oxidation in Health and Disease provides an up-to-date review of the role of oxidized lipid products in physiological and pathophysiological processes. Covering the diverse topics that contribute to research in this important field, this book explores: The mechanisms of lipid oxidation, both enzymatic and non-enzymatic Antioxidant defenses and lipid oxidation Lipid oxidation products and cell signaling The roles of oxidized lipids in specific diseases—including cardiovascular, neurodegenerative, and metabolic disorders, as well as in cancer Drug targeting and the therapeutic potential of oxidized lipids Accurate measurement of the formation of lipid oxidation products and investigation of their biological effects and roles in disease are critical to biomedical science and new targeted therapeutics. Written by acknowledged experts in the field, this book provides a broad survey of both established knowledge and recent findings on the action of oxidized lipid products on cell signaling and gene expression in health and disease.

This book was released on 2013-06-29 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 book was released on 2012-12-06 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contents of this book are the proceedings of the ACS symposium, "Impact of Processing on Food Safety," which was held April 16-17, 1997, at the American Chemical Society National Meeting in San Francisco, CA. This symposium brought together re searchers from diverse backgrounds in academia, government, and industry. Twenty speakers discussed topics ranging from the regulatory aspects of food processing to the microbiological and chemical changes in food during processing. The main goal of food processing is to improve the microbial safety of food by de stroying pathogenic and spoilage organisms. Food processing can also improve food safety by destroying or eliminating naturally occurring toxins, chemical contaminants, and antinutritive factors. Unfortunately, processing can also cause chemical changes that result in the formation of toxic or antinutritive factors. The purpose of this book is to summarize our knowledge of both the beneficial and deleterious effects of processing. Chapter I con siders the consumer's perceptions about food contaminants and food processing. Chapter 2 summarizes the effects of traditional and nontraditional processing methods on microor ganisms in food. Chapters 3-6 review the effects of processing on lipids (fatty acids and cholesterol) in food. Changes in the nutritive value of vitamins and minerals as a result of processing are discussed in chapter 7. Chapter 8 concentrates on how processing reduces the allergenicity of some foods.

Download or read book Biochemistry of Foods written by N.A.M. Eskin and published by Elsevier. This book was released on 2012-12-02 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Omega-3 Delivery Systems: Production, Physical Characterization and Oxidative Stability offers the most recent updates for developing, characterizing, and stabilizing both traditional and novel omega-3 delivery systems, including their final incorporation into food matrices and physicochemical changes during digestion. The book brings chapters on novel omega-3 delivery systems (e.g., high-fat emulsions, Pickering emulsions, electrosprayed capsules, and solid lipid nanoparticles), the application of advanced techniques to evaluate physical and oxidative stabilities (e.g., SAXS, SANS, ESR, and super-resolution fluorescence microscopy), and new developments of food enrichment and physicochemical changes during digestion. The book provides a unique multidisciplinary and multisectoral approach, i.e., featuring authors from industry and academy. Long chain omega-3 polyunsaturated fatty acids (PUFA) present numerous health benefits; however, the consumption of natural products rich in omega-3 PUFA (e.g., fish, krill, and algae) is not enough to reach the daily-recommended values. Therefore, the food industry is highly interested in producing omega-3 fortified foods. Brings a holistic approach of omega-3 delivery systems, bringing scientific understanding on production, physical characterization, and oxidative stability Covers key aspects to develop, characterize, and use omega-3 delivery systems for food enrichment, considering physicochemical changes occurring during digestion Serves as an interface between lipid oxidation and colloids chemistry, encapsulation techniques, soft matter physics, food development, and nutrients bioavailability
