This book was released on 1993 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research was to evaluate the effects of dietary heated fats from a commercial deep-fat frying operation and of cyclic fatty acids (CFA) on rat liver enzyme activity. The fats were partially hydrogenated soybean oil (PHSBO) used 4 days (4-MH) and 7 days (7-DH) for frying foodstuffs. Balanced diets containing these used fats were fed to rats for 10 weeks. In a second experiment, rats were pair-fed diets containing graded doses of 7-DH. In a third, 0.15% CFA diet was fed to animals. In a fourth, rats were pair-fed diet containing the 7-DH treated (T-7DH) with magnesium silicate which removes some polymers from the used oil. All four sets of experiments were conducted with control rats fed non-heated PHSBO (NH) diet. All diets were isocaloric with 15% fat. Animals fed 7-DH diet either ad libitum or by pair-feeding, showed significant increased contents of cytochromes P$sb{450}$ and b$sb5$ as well as increased activity of (EC 1.6.2.4) NADPH-cytochrome P$sb{450}$ reductase when compared to controls. The 4-MH diet group showed the same trends for cytochromes contents and reductase activity in comparison to controls. Similar results were obtained with CFA diet. The activities of (EC 2.3.1.21) carnitine palmitoyltransferase-I; (EC 1.1.1.42) isocitrate dehydrogenase; were significantly decreased in each case either ad libitum or by pair-feeding in comparison to controls. Significantly depressed activity of (EC 1.1.1.49) glucose 6-phosphate dehydrogenase was also noticed for these animals when compared to NH. Similar results were recorded when fed CFA diet to rats. In addition, liver and microsomal protein were significantly increased when the used oils were fed to rats either ad libitum or by pair-feeding in comparison to NH. Enlarged and fatty livers were noted. Similar results were obtained when fed CFA diet. Liver glycogen was significantly decreased when fed the used oils or CFA diets in comparison to controls. However, when animals were fed T-7DH diet, the activities of the enzymes were significantly improved.

Available in PDF, EPUB and Kindle. Book excerpt: Provides researchers, medical personnel, nutrition students, and others with an up-to-date view of several aspects of fat digestion and absorption and describes potential and realized applications. Topics addressed include enzymatic aspects of fat digestion in the gastrointestinal tract; the uptake of fat digestion products in the brush border membrane, the intracellular transport, and incorporation of these substances in glycerolipids and chylomicrons, or their portal transport; methods used to evaluate fat absorption; the effects of the triglyceride structure on fat digestion and absorption; an overview of fat absorption and studies related to malabsorption due to pancreatic and bile acid deficiency states; the effects of simulated household heating on fat absorption; and the reduction of fat uptake, either by feeding unabsorbable food fats or by interference with the digestion process of usual food fats by pharmacological means.

Download or read book Frying of Food written by Dimitrios Boskou and published by CRC Press. This book was released on 1999-07-21 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important resource concentrates mainly on two factors that influence the deterioration of a fat at elevated temperatures: the nature of the heated fat and the presence of oxidation retardants, especially those naturally occurring in oils or obtained from natural sources. Discussions include important biologically active ingredients present in oils and fats and minor constituents, which appear to affect the performance of a heated oil and/or may also be categorized as functional. Frying of Food also discusses olar phenolic compounds which have an impact on the stability of oils at high temperatures.
Download or read book Fatty Acids in Foods and their Health Implications Third Edition written by Ching Kuang Chow and published by CRC Press. This book was released on 2007-11-19 with total page 1296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the bestselling second edition, mounting research into fatty acids reveals new and more defined links between the consumption of dietary fats and their biological health effects. Whether consuming omega-3 to prevent heart disease or avoiding trans fats to preserve heart health, it is more and more clear that not only the quantity but the type of fatty acid plays an important role in the etiology of the most common degenerative diseases. Keeping abreast of the mechanisms by which fatty acids exert their biological effects is crucial to unraveling the pathogenesis of a number of debilitating chronic disorders and can contribute to the development of effective preventive measures. Thoroughly revised to reflect the most resent research findings, Fatty Acids in Foods and their Health Implications, Third Edition retains the highly detailed, authoritative quality of the previous editions to present the current knowledge of fatty acids in food and food products and reveal diverse health implications. This edition includes eight entirely new chapters covering fatty acids in fermented foods, the effects of heating and frying on oils, the significance of dietary ?-linolenate in biological systems and inflammation, biological effects of conjugated linoleic acid and alpha-linolenic acid, and the role of fatty acids in food intake and energy homeostasis, as well as cognition, behavior, brain development, and mood disease. Several chapters underwent complete rewrites in light of new research on fatty acids in meat, meat products, and milk fat; fatty acid metabolism; eicosanoids; fatty acids and aging; and fatty acids and visual dysfunction. The most complete resource available on fatty acids and their biological effects, Fatty Acids in Foods and their Health Implications, Third Edition provides state-of-the-science information from all corners of nutritional and biomedical research.

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.
