  • 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 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¡ë~3¡ë phosphoric acid and a proper amount of water to treat the crude rice bran oil at 90 °C for degumming.
  • 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.
  • Can rice bran be treated with enzymes?
  • Treating rice bran with enzymes is a new oil processing technology. In this 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 to increase nutrient content in rice bran oil?
  • At present, to increase the nutrient content in the refined rice bran oil, some manufacturers extract these bioactive compounds from the by-products of rice bran oil processing (soap-stock, deodorized distillate, etc.) and then add them back.
  • 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.
