摘要
比较了相同提取条件下正己烷与异丙醇提取小米谷糠油的得率。结果发现:异丙醇提取的小米谷糠油得率比正己烷高4.83百分点,可以达到25.32%。异丙醇在不同提取条件下提取小米谷糠的正交试验表明:当提取温度70℃,提取时间4 h,提取4次时,小米谷糠油得率最高,为25.61%;当提取温度60℃,提取时间4 h,提取3次时,小米谷糠油中甾醇含量为1.394%,油得率为24.75%。
The oil yields of millet bran extracted with hexane and isopropanol in the same conditions were compared. The results showed that the oil yield of isopropanol extraction was 25.32%, which was 4. 83% more than that of hexane. The orthogonal test showed that the highest oil yield was 25.61% under extraction conditions of 70 ℃, 4 h and extraction 4 times ; and under extraction conditions of 60℃, 4 h and extraction 3 times, the sterol content and the oil yield reached 1. 394% and 24.75%, respectively.
