国家林业局重点科研项目!“油茶高产栽培技术及深度加工利用”；

本校为第一机构

初步研究了用超临界CO2流体萃取茶油的工艺,探索了不同时间、压力、温度条件下对茶油提取率的影响.结果表明,当萃取时间3～4 h,压力35～40 MPa,温度40～50℃时,即可获得90%以上的提取率,且用此法萃取的茶油纯度较高,可以省略油脂的精炼工艺.

A technology of isolation of oil of oiltea camellia with supercritical CO_2 as a solvent was described. The effect of different pressure,time and temperature on extraction yield were studied. The results showed that the efficient conditions were at 3 ~ 4 h, 35 ~ 40 MPa, 40 ~50℃. Above 90% oil could be extracted. The experimental results showed that the SC-CO_2 extraction had a...
