Abstract:

In order to explore the oxidative stability of coix seed oil, acid value and peroxide value of coix seed oil stored under different conditions such as temperature, light, air and antioxidants were measured. Results showed that temperature, light and air all could accelerate the oxidation of coix seed oil and among them temperature was the most critical factor. Higher stability was observed in coix seed oil with the additions of antioxidants such as vitamin E and TBHQ. Furthermore, vitamin E exhibited stronger antioxidant effect than TBHQ.

Key words: coix seed oil, oxidative stability, acid value, peroxide value
