摘要
米糠浸出毛油所含的胶杂种类多,组分复杂,对精炼效果影响大,必须选择合适的脱胶方法加以脱除。通过对多种脱胶方法的试用和比对,发现草酸脱胶法对米糠浸出毛油脱胶效果比较理想。介绍了草酸脱胶的工艺流程、生产效果及对后续精炼工序的影响;米糠浸出毛油经过草酸脱胶,再结合脱色、脱蜡和物理脱酸等过程,可以生产出质量稳定、色泽清淡的米糠成品油。
The solvent influenced the refining extracted crude rice bran oil contained many kinds of gum impurities, which badly effect of the oil. Proper degumming method should be chosen to remove the gum impurities. The oxalic acid degumming process, the production effect and its influence on the following procedure were described. The results showed that the refined rice bran oil with stable quality and light color could be produced through a series of oxalic acid degumming, bleaching, dewaxing and physical refining processes.
