不同方法提取芹菜籽精油的比较研究

Comparative research on celery seeds essential oil prepared by different methods

应用有机溶剂提取(SE)、同步水蒸气蒸馏萃取(SDE)和超临界CO2流体萃取(SFE-CO2)方法提取芹菜籽中的活性成分,对不同提取方法制备的芹菜籽油进行了得率、制备工艺、感官评定等方面的研究。结果表明:超临界萃取优于常规方法,并确定了超临界CO2萃取芹菜籽精油的最佳工艺条件为:原料粒度60目,温度45℃,压力20MPa,流量15L/h,萃取时间2h。

Extracted celery seeds oil by different methods including organic solvent extraction （SE）, simultaneous water distillation-solvent extraction（SDE） and supercritical carbon dioxide fluid extraction（SFE- CO2）. Studied the yield, technology and flavor character of celery seeds oil from different methods. Experimental results show that： SFE-CO2 is the best, and the optimum technological condition of extracting oil from celery seeds was defined： particle size 60 meshes, temperature 45 ℃, working pressure 20 MPa, CO2 flow 15 L/h, operating time 2 h.
