Study on physical and chemical index and volatile components from hot processing sweet apricot kernel oil under three storage temperatures

In order to explore the storage quality change of hot processing apricot kernel oil at 37, 25 and 10℃, the traditional physical and chemical index, such as acid value, peroxide value, Euv232, Euv268, and the volatile components change of apricot kernel oil during the storage have been studied using HS-SPME/GC analysis techniques and traditional analysis techniques.The result showed that changing of index of apricot kernel oil under three storage conditions was very obvious, especially for the apricot kernel oil at 37℃ (acid value, peroxide value, Euv232 and Euv268 ascend 409% , 242% , 27% and 49% , respectively) , but it was appear gentle for the apricot kernel oil under refrigerated condition while the acid value, peroxide value, Euv232 and Euv268 separately increment by 255% , 66% , 36% and 64%.
