一种米糠油的精炼方法
摘要：
一种米糠油的精炼方法，是在毛糠油中加入0.5－3％的乙醇胺于室温下搅拌反应0.5－1小时，离心分离，得到粗糠油，然后用软水搅拌水洗粗糠油至少一次，最后分离、静置，上清液即是精制米糠油，外观澄清透明，色泽淡黄微红，酸值在6以下，一次水洗精炼得率≥55％。本方法只使用少量乙醇胺即可对毛糠油进行精炼，脱胶脱酸，改善色泽，降低酸值；且在室温、常压下操作，使工艺大大简化。
摘要（英）：

The rice bran oil refining process includes adding ethanolamine in 0.5-3 % into raw rice bran oil stirring at room temperature to react for 0.5-1 hr, and centrifugally separating to obtain coarse rice bran oil; washing with soft water for at least one time; and final standing to separate out the supernatant as the refined rice bran oil, which is clear, transparent, reddish yellow and has acid value below 6 and yield not lower than 55 %. The said process of refining rice bran oil can degum, deacidify, improve color and lower acid value, and is simple.
