  • What are the technologies of rice bran oil?
  • The processing technologies of rice bran oil include degumming, deacidification, dewaxing, etc.. These technologies help refine the oil and maintain its bioactive compounds.
  • Can rice bran be treated with enzymes?
  • Treating rice bran with enzymes is a new oil processing technology. The cell tissue of rice bran is hydrolyzed with protease and then oil is released to achieve the purpose of oil extraction (Hanmoungjai et al. 2001).
  • How is rice bran oil extracted?
  • Rice bran oil is extracted from rice bran, which contains about 15¨C20% crude oil. The extraction methods include pressing, solvent extraction, supercritical carbon dioxide extraction, and enzymatic extraction.
  • What can rice bran be used for?
  • In addition to the main product of rice processing, the by-products, such as broken rice, rice bran, rice embryo, rice husk, etc. can also be refined into high-value products. Rice bran, for example, can be used to extract oil, but these technologies are still limited in China and some other developing countries.
  • What is the process to refine rice bran oil?
  • To refine rice bran oil, the following steps are taken: hydration degumming, active clay decolorization, steam deacidification and deodorization, and low-temperature freezing dewaxing. Specifically, degumming involves adding 2¡ë~3¡ë phosphoric acid and a proper amount of water to treat the crude oil at 90 °C.
  • What is deacidification of rice bran oil?
  • Deacidification is the process of removing free fatty acids from crude rice bran oil. This process can be achieved through various methods such as alkali refining, distillation, mixing, re-esterification, and extraction. Among these, alkali refining has comprehensive effects like deacidification and decolorization, but it results in higher refining loss.
