| 摘 要： | 通过超临界CO2流体萃取大豆胚芽油的实验,探讨了萃取压力、萃取温度、萃取时间和CO2流量对大豆胚芽油萃取率的影响。结果表明,最适宜的萃取条件为萃取压力30MPa、萃取温度45℃、萃取时间120min、CO2流量25kg/h,在此条件下萃取率为91.38%;超临界CO2法得到的大豆胚芽油不饱和脂肪酸含量为84.2%,其中亚麻酸和亚油酸占74%,碘值为152gI/100g。

| Abstract: | Clearly demonstrated the principal factors affecting the extraction of soy germ oil with supercritical CO2 fluid. These were extracting pressure, extracting temperature, extracting period, and CO2 flowing rate. The results showed that satisfactory extracting conditions: extracting pressure of 30 MPa, extracting temperature of 45 ℃ for 120 minutes at CO2 flowing rate of 25 kg/h. Under these conditions, the yield of soy germ oil reached 91.38%. At the same time we analyzed the Compositions on extracting of soy germ oil with supercritical carbon dioxide. Supercritical carbon dioxide method got the unsaturated fatty acid content as 84.2%, among them, linolenic acid and linoleic acid account for 74%, its iodine value is 152 gI/100g. |
