摘  要：
[目的]研究超临界CO2萃取大蒜油最佳工艺。[方法]在设计单因素试验优化超临界CO2萃取大蒜油工艺条件的基础上,采用正交试验确定超临界CO2萃取大蒜油最佳工艺。[结果]影响大蒜油萃取率的主次因素为:萃取压力>萃取时间>萃取温度;超临界CO2萃取大蒜油的最佳工艺条件为:以15%(V/W)无水乙醇为夹带剂,萃取温度40℃,萃取压力25MPa,萃取时间2.5h,CO2流量80L/h;在此工艺条件下,萃取率可达0.461%。[结论]该研究改进了超临界CO2萃取大蒜油工艺条件,为大蒜油的工业化萃取提供了理论依据。

摘  要：
[Objective] The optimum process of garlic oil extraction by supercritical CO2 was studied.[Method] First,the single factor experiments were carried out to optimize the process of the extraction of garlic oil by supercritical CO2,on that basis,the best process conditions were obtained by the orthogonal experiments.[Result] The primary and secondary factors which affect the extraction rate were showed as following:extraction pressure > extraction time> extraction temperature.The optimum process conditions of garlic oil extraction by supercritical CO2 from the garlic were showed as following:taking 15% ethanol as entertainer,extraction temperature 40 ℃,extraction pressure 25 MPa,extraction time 2.5 h and the flow of carbon dioxide was 80 L/h.Under these conditions,the extraction yield was 0.461%.[Conclusion] These primary results improved the process of garlic oil extraction,and provided the theoretic basis for the industrial extraction of garlic oil.
