Abstract:
Soybean germ contains about 8% of oils，most of which are unsaturated fatty acids.Extraction technique of soybean germ oil by supercritical carbon dioxide method was studied by orthogonal test.Through the response surface optimization method，the optimum extraction temperarure，pressure，time and ultrasonic power for the maximum estraction was 37℃，26.3 MPa，29 min and 300 W，respectively.The extraction rate of soybean germ reached 87.24 %，and the oil had transparent pale yellow color and pure taste.
