| Abstract: | Supercritical CO2 was applied to extract oil from grape seed,and the chemical composition of grape seed oil was analyzed by gas chromatography.The results showed that the optimum extraction conditions were extraction pressure 30 MPa,temperature 40℃ and time 90 min by orthogonal experiment.Under such conditions,the extraction rate reached 89.4%.In the grape seeds oil,the content of unsaturated fatty acid was relatively high,and could reach 88.3%,which mainly included 69.9% of linoleic acid and 18.4% of oleic acid.Saturated fatty acids were mainly stearic acid and palmitic acid,and they accounted 3.6% and 8.1%,respectively. |
