In different fats, and under different conditions, autoxidation produces tal- lowy, painty, burned, fishy, grassy, and other off-flavors and odors; the senses of taste and smell can detect autoxicla- tive deterioration quite readily.

Simic Center for Radiation Research, National Bureau of Standards, Washington, D C. Air-induced oxidation of organic and inorganic systems, which is actually a result of direct or indirect action of mo- lecular oxygen (dioxygen), usually goes through free radical processes and is commonly described as autoxidation.
The present review intends to provide an overall and critical picture of cholesterol photosensitized oxidation in food and biological systems, and its possible impact on human health and well.

Agric. and Food Chem. – FREE RADICAL AUTOXIDATION The biological consequences of oxidized lipids that arise from in vivo reactions or from ingested foods long have attracted the attention of biochemists and food scientists.
Many researchers are now working worldwide on a wide assortment of biological systems. Effect of Ascorbic Acid on Lipid Autoxidation in a Model Food System.

25, No. 4, pp. Consequences of protein oxidation. Reactive oxygen species (ROS), which may be present in biological systems and, to some extent, in food, include superoxide, hydrogen peroxide, hydroxyl radical, and peroxynitrite, and these are able to induce protein damage. The book belongs to the Food Science and Technology series of monographs.
It is not surpris- ing therefore that much of the emphasis is oriented towards the implications of lipid peroxidation pro- cesses in foodstuffs and related biological systems. Some of the more far-reaching aspects and conse. Autoxidation. Autoxidation is any oxidation that occurs in open air or in presence of oxygen (and sometimes UV radiation) and forms peroxides and hydroperoxides.
HYDROGENATION. Liquid oils can be converted to solid fats by the process known as hydrogenation. In this process there is an addition of hydrogen to unsaturated fat thus converting oils into solid fats. for complex food and biological systems. The test is not specific and can interact with other non-oil minor components (DNA, sugars).
Iodine value (IV) The IV (“iodine adsorption value” or “iodine number” or “iodine index”) measures the number of reactive double bonds present in an oil.
A higher IV number indicates more double bonds in. Autoxidation, however, is more complex, and involves at least another path, which was elucidated by the combined effort of several authors (Antonini and Brunori, ; Wallace et al., ; Brantley et al., ).A crucial observation was that the autoxidation rate exhibits a bell-shaped dependence on O 2 partial pressure, being maximal at partial saturations ( to ) and declining at.
Autoxidation in food The prevention of autoxidation is important in the food and drink industry and is achieved both by both chemical preservatives and a range of oxygen excluding food preservation techniques such as canning.
Autoxidation of lipids in biological systems is a direct process that occurs by homolysis of endogenous hydroperoxides by scission of ROOH and production of RO.
and ROO. The polyunsaturated fatty acids such as linoleic and arachidonic acids, which are present as phosphoglyceride esters in lipid membranes, are particularly susceptible to. Based on years of academic and industrial research by an international panel of experts, Chemical, Biological, and Functional Properties of Food Lipids, Second Edition provides a concise, yet well-documented presentation of the current state of knowledge on lipids.

Piloni and Susana Puntarulo. Submitted: November 12th Reviewed: April 24th Published: August 29th DOI: / In this study, the products formed by epoxidation with m-chloroperbenzoic acid (MCPBA), oxidative cleavage with KMnO 4, and autoxidation in low-moisture and aqueous model systems, in the presence and absence of light, at ambient condition were identified.
The presence of oxidation products was also verified in processed products (tomato juice. Abstract | Lipid oxidation is a major cause of deterioration in the quality of food and food products. Oxidation can occur in both triglycerides and phospholipids of food because lipids are divided into two main classes; polar lipids (phospholipids) and neutral lipids (triglycerides).

This book covers the latest findings on how information is processed in various biological. Autoxidation of polyunsaturated fatty acids is one of the most important reactions in food and biological systems and can only be completely prevented by the total exclusion of oxygen (Pokorny.
Antioxidant Defenses in Biological Systems • Fat-soluble cellular membrane consists – Vitamin E – beta-carotene – Coenzyme • Water soluble antioxidant scavengers – Vitamin C – Glutathione peroxidase, – Superoxide dismutase – Catalase 19 Synthetic antioxidants PGTBHQ 20 The rate of quercetin autoxidation can be fitted to a monoexponential first-order decay with a k value of × 10 −2 M −1 s −1.
Comparison of quercetin oxidative products in the different systems provides a deeper insight into the underlying mechanism involved in the oxidation process.
Formation of complexes of catechol with iron or copper were investigated, in particular, with respect to the effect of pH, buffer, and rate and degree of oxidation on these systems.
Many other organic compounds are shown to form analogous complexes. Ascorbic acid formed a complex similar to that of catechol since not only were both complexes coloured between pH 6 and 9 but both were also. 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.
The biological effects of excess levels of the spectrum of these species are quite similar, and that is the reason they are collectively called reactive oxygen species (ROS).

Food Oxidants and Antioxidants: Chemical, Biological, and Functional Properties provides a single-volume reference on the effects of naturally occurring and process-generated prooxidants and antioxidants on various aspects of food quality. The book begins with a general introduction to oxidation in food and then characterizes the main oxidants.In biological systems these RNS not only originate from the biosynthesis of NO but also from exogenous sources such as polluted air and dietary nitrite.
While the ability of NO2 to induce lipid peroxidation has been long known, more recent studies have discovered novel processes that have been termed lipid nitration.
Physical Chemistry's Understanding. Biological oxidation-reduction reactions, or simply biological oxidations utilize multiple stages or processes of oxidation to produce large amounts of Gibbs energy, which is used to synthesize the energy unit called adenosine triphosphate or efficiently produce ATP, the process of glycolysis must be near an abundance of oxygen.
