摘要
【目的】研究小麦胚芽油的出油量与各影响因素之间的关系并确定最佳的工艺条件,为工业化生产提供参考;【方法】通过单因素试验和正交试验确定最佳工艺技术参数;【结果】研究了超临界CO2萃取小麦胚芽油的主要影响因素:萃取压力、萃取温度和CO2流量,并得到最佳的工艺条件:萃取压力为25MPa,萃取温度为38℃,CO2流量为10kg/h;【结论】利用超临界CO2流体萃取小麦胚芽油具有工艺简便易分离,无溶剂残留等特点,工业化生产是可行的。
[OBJECTIVE]The extraction of wheat germoil was investigated by supercritical CO2 fluid extraction（SFE-CO2）;[METHOD] Conditions of the extraction were studied using single factor experiment and four-factor and there-levelorthogonal design method as guided by extraction yield;[RESULTS]the optimized conditions were established as follows：extraction pressure 25MPa、extraction temperature 38℃、CO2flow rate 10kg/h;[CONCLUSION]The extraction of wheat germoil by supercritical CO2 fluid extraction is feasible.
