Acceleration of Lipid Oxidation by Volatile Products of Hydroperoxide Decomposition (original) (raw)

Safflower oil, methyl oleate, and methyl linoleate were oxidized in a closed system where they were in contact with vapor space over previously oxidized methyl linoleate. The volatile compounds resulting from linoleate oxidation greatly accelerated peroxidation of the oil and the two esters. Similar results were obtained when safflower oil and methyl esters of oleic acid and linoleic acid were contacted with vapor phase over hexanal or 2,3decadienal, both of which are major products of decomposition of peroxides formed from peroxidized linoleate.
