  • 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.
  • How is rice bran oil extracted?
  • There are about 15–20% crude oil in rice bran; normally, the rice bran oil is extracted by pressing or solvent extraction methods, such as supercritical carbon dioxide extraction and enzymatic extraction, and then refined by decolorization, deodorization, or other processes.
  • Does rice bran oil hydrolyze after milling?
  • However, after the rice is milled, lipase is transferred into the rice bran, and oil hydrolysis occurs quickly. The acid value of fresh rice bran oil rises significantly in the first 6 hours and will bring an undesirable factor for further rice oil processing (Wu et al. 2020).
  • 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.
