Abstract: Conjugated linoleic acid(CLA) was prepared from sunflower oil, while L-ascorbyl palmitate, L-ascorbyl laurate and D-isoascorbyl palmitate were prepared from L-ascorbic acid, D-isoascorbic acid, palmitic acid and lauric acid. Effects of the three esters on protecting CLA from oxidation were studied. Results showed that the antioxidant effects of the three esters in different amounts(0.02%, 0.04% and 0.08%) on CLA are prominent and similar with each other. They can be used as good and safe antioxidants for commercial CLA.

Key words: conjugated linoleic acid, L-ascorbyl palmitate, L-ascorbyl laurate, D-isoascorbyl palmitate, antioxidation
