| Abstract: |
| The rice bran oil is hard to refine for its high impurities,high acid value and deep color. The crude rice bran oil (containing 3%-12% wax,280-300 mg/kg phosphorus,6%-7% sugar ester and 7%-9% solid fat) with the acid value 25-26 mgKOH/g and peroxide value 5 mmol/kg was used as the material, and the refining process of the degumming with alkali after acid processing, pre-and re-bleaching, dewaxing, physical deacidification and deodorization, defatting was described.After refining, the first-grade rice bran oil containing 0.9% trans fatty acid could be obtained. The yield of the finished liquid oil was 61.6%,and the shelf life was greater than or equal to 14 months. |
