亚临界流体萃取技术提取柚皮精油的工艺优化
目的  优化亚临界流体萃取技术提取柚皮精油的工艺条件。方法  以萃取时间、料液比、夹带剂的添加量为考察因素, 以精油的提取率为实验指标进行单因素及正交试验设计。结果  亚临界流体技术萃取柚皮精油的最优的工艺条件是萃取时间40 min、料液比1:7(m:V)、夹带剂添加量0.6 mL/g, 在此条件下, 柚皮精油达到最高提取率, 为1.35%。结论  亚临界流体萃取技术提取柚皮精油是一种提取率比较高的方法。

Objective  To optimize the process conditions of extracting pomelo peel oil by subcritical fluid extraction. Methods  The extraction time, the ratio of material to liquid and the amount of entrainer were taken as the factors, the single factor and orthogonal experiments were carried out with the extraction rate of essential oil as the experimental index. Results  The optimal process conditions for the extraction of pomelo peel oil by subcritical fluid technology were extraction time 40 min, ratio of material to liquid 1:7(m:V), entrainer addition amount 0.6 mL/g. Under these conditions, pomelo peel essential oils reached a maximum extraction rate of 1.35%. Conclusion  Subcritical fluid extraction technology for extracting pomelo peel oil has a relatively high extraction rate.
