  • What is rice bran oil refining process?
  • The rice oil refining process generally involves deacidification, decolorization, deodorization, and triglyceride removal (Table 4). The byproducts of rice bran oil refinement can also be used to extract bioactive substances, such as ¦Ã-oryzanol and tocopherol. Table 4. Refinement and extraction of active substances. 5.2.1. Deacidification
  • What technologies are used in rice bran oil extraction?
  • New combined technologies have emerged to improve the efficiency and quality of rice bran oil. These include enzyme-assisted extraction, ultrasound-assisted water extraction, supercritical and subcritical CO 2 extraction, microwave-assisted extraction, and subcritical fluid technology. All these have broad application prospects . 5.1.1.
  • Why is rice bran crude oil difficult to refine?
  • The high acid value and dark color of rice bran crude oil make it difficult to refine rice oil. Nutrients are readily lost during the refining process. In addition, the production of trans-fatty acids, 3-chloropropanol ester, and other potentially harmful substances affects the quality and safety of rice oil products.
  • Can degumming & dewaxing be used for rice bran oil refining?
  • A new process for the physical refining of rice bran oil through combined degumming and dewaxing was developed on a laboratory scale and then demonstrated on a commercial scale.
  • Does delayed stabilization affect the quality of rice bran oil?
  • Research has found that a delayed stabilization treatment of rice bran seriously affects the overall quality of rice bran oil. Compared with traditional solvent extraction, the new extraction technologies have improved the yield and nutritional value of rice bran oil, but most of them are still in the research stage.
  • How is rice bran oil extracted?
  • Table 3. New rice bran oil extraction technology. Mechanical pressing is a conventional extraction technique that does not involve heat treatment or any organic solvent and is less expensive than solvent extraction.
