| 中文摘要: |
| 对翅果油的超临界CO2流体萃取工艺条件进行研究。在单因素试验的基础上，以萃取压力、萃取温度、萃取时间和原料粒度为影响因素，以翅果油得率为指标，采用正交试验优化工艺条件。比较了浸出法、超临界CO2流体萃取法、冷榨法和热榨法4种不同提取方法对翅果油得率和微量活性成分的影响。结果表明：超临界CO2流体萃取翅果油最优工艺条件为萃取压力30 MPa、萃取温度50?℃、萃取时间150 min、原料粒度80目，此条件下翅果油得率为（28.32±115）%；4种提取方法中，浸出法的翅果油得率、VE及甾醇含量最高，其次是超临界CO2流体萃取法，除热榨法的翅果油角鲨烯含量最高外，压榨法的其他指标均最低。 |
| 英文摘要: |
| The extraction process conditions of Elaeagnus mollis Diels seed oil by supercritical CO2 fluid (SC-CO2) was studied.Based on single factor experiment, with extraction pressure, extraction temperature, extraction time and raw material particle size as the influence factors, and the oil yield as indicator, orthogonal experiment was conducted to optimize SC-CO2 extraction conditions. The effects of four extraction methods including solvent extraction, SC-CO2 extraction, cold pressing and hot pressing on the oil yield and trace active component content of E. mollis Diels seed oil were compared. The results showed that the optimal SC-CO2 extraction conditions of E. mollis Diels seed oil were obtained as follows: extraction pressure 30 MPa, extraction temperature 50?℃, extraction time 150 min and raw material particle size 80 meshes. Under these conditions, the yield of E. mollis Diels seed oil was （28.32±1.15）%. In the four extraction methods, the oil yield and contents of VE and sterol in E. mollis Diels seed oil obtained by solvent extraction were the highest,followed by SC-CO2 extraction. Except for the highest squalene content in E. mollis Diels seed oil by hot pressing, the other indexes of E. mollis Diels seed oil by cold pressing and hot pressing were the lowest. |
