  • What are the steps in a rice bran oil refining process?
  • The steps in the process of refining rice bran oil are given in Fig. 14.1. The first step in the refining process with crude rice bran oil is usually dewaxing or winterizing. However, for other vegetable oils, the dewaxing step can be done at different times in the refining process.
  • What are the technologies of rice bran oil?
  • After that, the fatty acid composition, bioactive compounds, and the processing technologies of rice bran oil are described and the refining technology of rice bran oil (degumming, deacidification, dewaxing, etc.) as well as the technologies to remaining the bioactive compounds in rice bran oil are introduced.
  • What is deacidification of rice bran oil?
  • Deacidification is the process of removing free fatty acids from crude rice bran oil. The deacidification methods of rice bran oil include alkali refining, distillation, mixing, re-esterification, and extraction. The alkali refining method has comprehensive effects such as deacidification and decolorization, but the refining loss is much higher.
  • How to refine rice bran oil?
  • In industrial production, rice bran oil is mostly refined by hydration degumming, active clay decolorization, steam deacidification and deodorization, and low-temperature freezing dewaxing. The specific method is to add 2‰~3‰ phosphoric acid and a proper amount of water to treat the crude rice bran oil at 90 °C for degumming.
