摘要
以超临界CO2萃取技术从三叶木通种子中萃取脂肪油,探讨萃取压力、萃取温度对萃取收率的影响,以及分离压力对脂肪油酸值的影响,确定最佳萃取工艺条件为:萃取压力30 MPa,萃取温度45℃,分离釜Ⅰ压力11MPa,分离釜Ⅰ温度50℃,分离釜Ⅱ压力6 MPa,分离釜Ⅱ温度45℃,萃取时间2 h。同时将该方法与传统溶剂提以法进行比较,并进行GC-MS分析,实验结果表明两种方法提取的油的组成基本一致,不饱和脂肪酸含量较高。
The extraction of fatty oils from the seed of Akebia trifoliata （Thunb） Koidz with supercritical CO2 was studied. The effects of extraction pressure, extraction temperature on the yields were discussed. The optimal condition of this method was as follow： extraction pressure 30MPa, extraction temerature 45℃, separator I pressure l lMPa, separator I temperature 50℃, separator Ⅱ pressure 6MPa, separator Ⅱ temperature 45℃,extraction period 2 hours. Compared with the traditional solvent extraction, with a GC-MS analysis, it revealed that the component extracted with supercritical CO2 was basically consistent with that extracted with petroleum ether, and it was rich unsaturated fatty acid.
