采用半连续法研究了超临界二氧化碳(SC-CO2)萃取花生油的最佳萃取工艺条件,并将提取的花生油送至国家粮油质量监督检测中心检测.结果 表明,SC-CO2萃取花生油的最佳工艺条件为:萃取温度50℃,萃取压力30 MPa,动态萃取120 min.在此条件下出油率可达49％.检测结果显示:不溶性杂质含量＜00.003 2％,酸值＜12.5(KOH) mg/g,过氧化值＜1.6 mmol/kg,未检出溶剂残留.超临界萃取的花生毛油色泽清亮、淡黄透明、出油率高,重要参数均能达到国家一级油标准,证明超临界萃取技术是一种能高效萃取高品质花生油的方法.

The optimal extraction conditions of supercritical carbon dioxide(SC-CO2)extraction of peanut oil were studied by semi-continuous method,and the extracted peanut oil was sent to the National Grain and Oil Quality Supervision and Inspection Center for testing.The results showed that the optimum conditions for the extraction of peanut oil by SC-CO2 were as follows:extraction temperature 50℃,extraction pressure 30 MPa,and dynamic extraction 120 min.Under the conditions,the oil yield was up to 49%.Test results were insoluble impurities content
