Abstract: Oxidation stability of EAEP soybean oil under different temperature and storage time was studied. The quality parameters peroxide value, p- anisidine value, conjugated dienes, conjugated trienes was evaluated. The model accounting for the effect of temperature on oxidation rate was merged with the Arrhenius equation to get a model predicting shelf life on the basis of the concomitant changes in temperature. These results were time-dependent.The results showed that peroxide value, p- anisidine value, conjugated dienes, conjugated trienes follow the pattern that a higher rate of increment during early storage, then the rate decreased.The activation energy ( Ea) for the IP of EAEP soybean oil autoxidation was 72.10 k J / mol, storage at 60℃ revealing significantly temperature dependence for autoxidation in oil.The EAEP soybean oil should store at low temperature.
