• 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¨C20% 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.
  • What is rice bran oil?
  • Rice bran oil is an edible oil extracted from rice bran. Its fatty acid profile compared to other vegetable oils tends to be higher in oleic acid and lower in linoleic acid, similar to peanut oil in this regard.
  • How is crude rice bran oil refined?
  • The refining process for crude rice bran oil typically begins with dewaxing or winterizing. This step is necessary due to the fact that crude rice bran oil can contain up to 8% wax, depending on the extraction method.
  • In which countries is rice bran oil commonly used?
  • Rice bran oil is most commonly used in Japan and India, and to a certain extent in other parts of Southeast Asia, such as Thailand and Indonesia.
  • How much rice bran oil is produced in the world?
  • In 2005, approximately 2 million metric tons (MMT) of rice bran oil were processed in the world (FAO, 2007). However, if all the rice produced worldwide (598 MMT) was processed to extract lipids for rice bran oil, one could produce approximately 10 MMT.
