摘要: 采用超临界CO2萃取技术,对薜荔籽中薜荔籽油的萃取工艺进行探讨。研究粉碎度、萃取压力、萃取温度、CO2流量和萃取时间对薜荔籽油出油率的影响。实验表明,超临界CO2萃取薜荔籽油的最佳工艺参数是粉碎度40目、萃取压力25MPa、萃取温度40℃、CO2流量25L/h、萃取时间90min,薜荔籽油的出油率最高,达到20.93%。

Abstract: The supercritical CO2 extraction technologey was employed to extract oil from Ficus pumila L.seed. The effects of frinding degree,extraction pressure,extraction temperature,CO2 flow rate and the extraction time on the extraction rate of the Ficus pumila L. seed oil were discussed emphatically,and they were optimized by orthogonal test. The results showed that the optimal conditions of supercritical CO2 extraction are as follows: grinding degree 40 meshes,extraction pressure 25MPa,extraction temperature 40℃,CO2 flow rate 25L/h and extraction time 90 min. The maximum extraction rate of the Ficus pumila L.seed oil reaches 20.93%.
