摘要: 根据粗米糠油精炼和工艺方面的要求,确定温度、循环水量、油脂残留酸价、油脂中谷维素含量变化、液晶层高度、液晶层形成时间为工艺的主要影响因素。根据脂肪酸在一定pH值范围内转化为脂肪酸钠可以形成液晶相的原理,提出高酸价米糠油液晶态脱酸的新型工艺方法。

Abstract: Based on requests of coarse rice bran oil refining technology ,main effect factors were determined by temperature, circulation water quantity, oil remaining acid value, change of oryzanol content, height and forming time of liquid crystal. Based on principle that fatty acids can be transformed into fatty acid sodium in certainty range of pH, an efficient method was provided for separation of fatty acids in liquid crystal state of rice bran oil with high acid value.

Key words: rice bran oil, liquid crystal state, separation of fatty acids
