【摘要】 选用超临界CO₂萃取法提取大豆胚芽油。以单因素试验为基础,选取萃取温度,萃取时间,萃取压力,CO₂流量为主要考察因素,使用响应面设计法优化大豆胚芽油超临界提取工艺条件。优化后的提取工艺条件为提取温度45℃、萃取时间120 min、萃取压力为30 MPa、CO₂流量为30 kg/h,在此提取条件下平行实验3次,测得胚芽油出油率为（9.31±0.38）%,与预测值无显著差异。更多还原

【Abstract】 The soybean gern oil was extracted by supercritical CO₂ extraction. Based on single factor experiment, extration tempetature, extraction time, extraction pressure and CO₂ flow rate were seleted as major factors to optimize supercritical CO₂ extraction of soybean gern oil by response surface analysis. The optimized extraction conditions were as follows: extraction temprature 45 ℃, extraction time 120 min, extraction pressure 30 MPa and CO₂ flows rate 30 kg/h. Three parallel experiments were conducted under these conditions and the oil yield was（9.31±0.38）% which was not significantly different from the predicted value.更多还原
