Zur Bildung von Carbonylverbindungen in Fetten nach Einwirkung von Elektronenstrahlen

Summary Investigations of the formation of carbonyl compounds in fats subjected to electron rays (100 Mrad) have been reported. More than 20 different substances can be determined by gasliquid-chromatography. The splitting of the ester-C-O-C-bonds is mostly accompanied by a fracture of the fatty acid chain and carbonyl compounds with 6 to 12 C-atoms are essentially formed (aldehydes mostly up to 9 C-atoms). A relatively high concentration of unsaturated C₉-ketones and a small amount of ketones with more than 13 C-atoms has been found in irradiated tripalmitin and palmitic acid. None of these higher compounds could be detected in unsaturated oils, which contain more C₁₁- and C₁₂-ketones.
