摘要
本文系统地研究了棉籽油脱臭馏出物中甾醇提取方法,主要得出以下结论:采用转酯化-结晶法对棉籽油脱臭馏出物中甾醇进行萃取,最佳萃取条件为:料液比为1/5(m/V),转酯化温度为60℃,催化剂使用量为35%,转酯化时间为4 h,甾醇提取率为54.80%,甾醇纯度达到82.10%。
A process for extracting plant sterol fi＇om cotton oil deodorizer distillate and the crystal purification were studied. The optimal conditions for transesterification of sterol ester were obtained as followed： the rate of blend composition 1/5 （m/V ）, temperature 60 ℃, the dosage of catalyst 35% and time 4.0 hour. The recovery rate was 54.8% and purity of rough sterol was 82.10%.
