| Abstract: |
| Rice bran oil attracts more and more attention due to its rich nutritional contents. Rice bran is prone to rancidity, resulting in high acid value, difficult refining and low yield of crude rice bran oil, which restricts the development of rice bran oil industry. How to remove the impurities in crude rice bran oil efficiently and meanwhile maximumly retain the nutrients such as oryzanol and phytosterol, were great challenges for rice bran oil refining. Deacidification processes with alkali refining are generally applied in traditional rice bran oil processing. In recent years, new technologies such as physical refining by super degumming and enzymatic degumming have been used for rice bran oil refining in practice. The traditional chemical process and modern physical process of rice bran oil refining technology were reviewed so as to provide reference for rice bran oil refining. |
