Abstract

Ultrasonic wave-assisted extraction conditions of apple seed oil were optimized by quadratic general rotary design,and quadratic regression equations were established.The optimum parameters of ratio of liquid to solid,ultrasonic time and ultrasonic power were 8.13∶1,31.3 min and 165.2 W,respectively.Under the optimum conditions,the yield of apple seed oil was up to 24.40%.GC-MS analysis showed that the unsaturated fatty acids in apple seed oil were 85.31%,in which the content of oleic acid,linoleic acid were 35.05% and 49.19%,respectively.
