Abstract: The effects of tert-butylhydroquinone(TBHQ)and rosemary extract on the storage stability of Camelina sativa(L.)Crantz seed oil were studied by Schaal oven test and Rancimat experiment according to peroxide value(POV)and oxidation stability index(OSI). The effects of these antioxidants on fatty acid composition of Camelina sativa(L.)Crantz seed oil pre- and post accelerated oxidation were analyzed. The accuracy of the above two methods in predicting shelf life of Camelina sativa(L.)Crantz seed oil was evaluated. The results showed that the oxidation stability of Camelina sativa(L.)Crantz seed oil was poor,TBHQ and rosemary extract could prolong the storage period of Camelina sativa(L.)Crantz seed oil,among them the combination of 0.02%TBHQ and 0.04% rosemary extract was able to achieve the best effect and the expected storage time was extended to more than 608 days at 20℃.After accelerated oxidation,the proportion of polyunsaturated fatty acid(PUFA)was reduced by 59.8%,while the proportion of saturated fatty acid(SFA)and monounsaturated fatty acid(MUFA)were increased by 101.9% and 71.8% respectively. Significant correlation was observed between the fatty acid composition of Camelina sativa(L.)Crantz seed oil with different antioxidants and the results of shelf life predicted by Schaal oven test(P<0.01). There was great difference between Rancimat experiment and Schaal experiment and Schaal experiment was more accurate in predicting shelf life of Camelina sativa(L.)Crantz seed oil.
