INVESTIGATIONS ABOUT THE AUTOXIDATION OF FATS AND OILS BY A CHEMILUMINESCENCE METHOD

The oxidative stability of different oils was determined by a Rancimat apparatus. Samples of oils obtained at definite time intervals from t he Rancimat were measured by a chemiluminescence method. Thereby the h ydroperoxides formed during the first step of the autoxidation and rad icals react in presence of a catalyst with Luminol. The results are pr esented in dependence of the storage time and discussed with relation to the results of the Rancimat apparatus. There is a good correlation between both methods (r = 0.9865).
