超临界二氧化碳萃取磷脂的工艺研究

Stady on Technology of Phospholipids by Supercritical CO_2 Extraction

建立了用超临界二氧化碳萃取法从粗磷脂中萃取纯化磷脂的方法。考察了影响油脂萃取率的因素,采用正交实验确定了最佳萃取条件:萃取压力为30MPa,萃取温度为55℃,萃取时间为2h。大豆、葵花和胡麻三种磷脂得率分别为:88.5%、76.5%及79.2%,含磷量分别为:3.83%、2.62%及2.90%。

A method for refining coarse phospholipids by supercritical CO2 extraction was established. The experimental factors which have the effect on extraction rate were investigated, and extraction conditions were optimized as pressure 30Mpa,temperature 55℃,time 2 hours.
