Abstract

Soybean, cottonseed, and corn oils were hydrogenated to obtain triacyglycerols containing conjugated linoleic acids. The oxidative stability of soybean oil, cottonseed oil, and corn oil was less with CLA than without CLA during autoxidation. However, the autoxidative stability of oils increased as the CLA content increased. During photooxidation of oils, the oxidative stability of oils was higher with CLA than without CLA, and the stability of oils increased as the CLA content increased. The mechanisms of autoxidation and photooxidation of oils were probably due to the contents and anti- and prooxidant activities of individual conjugated linoleic acids in bulk oil, and minor compounds present in oils.
