✦ Synopsis

In the last decade, a multitude of secondary products have been identified from the radical and photosensitized oxidations of polyunsaturated lipids. These secondary products consist of oxygenated monomeric materials including epoxy-hydroperoxides, oxo-hydroperoxides, hydroperoxy epidioxides, dihydroperoxides, hydroperoxy bis-epidioxides, and hydroperoxy bicycloendoperoxides. More recently, higher molecular weight dimeric compounds have been identified from autoxidized methyl linoleate and linolenate. Decomposition of these oxidation products form a wide range of carbonyl compounds, hydrocarbons, furans, and other materials that contribute to the flavor deterioration of foods and that are implicated in biological oxidation. The interaction of some of these degradation products with DNA may be involved in cell-damaging reactions.

## Abstract Olive oil was converted into methyl esters which were autoxidized at 60 °C. The composition of oxidized products was determined by the comparison of infrared spectra and NMR spectra of the original and acetylated samples, the sample reduced with potassium iodide and the acetylated reduc

## Abstract The thermal treatment of vegetable oils was studied by gel chromatography on packings of styrene‐divinylbenzene copolymers. Unlike oils with a lower content of polyene acids, those with a high content of polyene acids contained a larger amount of higher oligomers of fatty acids. The gel
