Autoxidation of Unsaturated Fatty Acid Methyl Esters. I.

Journal of Japan Oil Chemists' Society, 1978
Methyl linoleate and its trans, trans isomer, methyl linolenate, and a mixture of methyl eicosapentaenoate and methyl docosahexaenoate (50 : 50%) were autoxidized in the conditions free from natural antioxidants and metals. Their autoxidations gave the induction period of 49, 52, 18 and 11h, and showed the oxidation rates of 3.61, 3.08, 5.24 and 9.41 ...
