富含谷维素的米糠油精炼方法研究

主要研究了米糠油的物理精炼方法,对米糠油的物理精炼工艺过程及其参数进行了深入的研究。物理精炼可以得到富含谷维素的三级米糠油,前脱蜡物理精炼米糠油工艺的成品油得率比后脱蜡工艺高0.5%,前脱蜡工艺成品油中谷维素含量达到1.72%,比后脱蜡工艺高出0.13%。

The physical refining crafts, especially about the dewaxing craft and the operation process of dewaxing craft was studied. The result indicated the physical refining crafts production according with the national Grade Ⅲ of rice bran oil. The refined oil yield and oryzanol content of the former dewaxing was higher than the latter 0.5%. And refined oil oryzanol content reached 1.72%, 0.13% higher than the latter.
