  • How is rice bran oil made in China?
  • Two refining processes, steam refining and miscella refining, are now the primary industrial techniques used for producing edible RBO in China. Steam refining usually produces refined RBO with a dark color, which is designated as grade-three or grade-four RBO according to the National Standard of China (GB19112 Rice Bran Oil) [ 4 ].
  • What is the first step in refining 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.
  • 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 you use rice bran for food?
  • A major problem of using RBO for food purposes is the time lag between bran production and oil extraction. Oil should be extracted immediately as soon as the bran is produced. Otherwise, oil will be hydrolyzed into free fatty acids (FFAs) and glycerol by the action of very active lipase enzymes present in rice bran.
  • How is rice bran oil processed?
  • Rice bran oil undergoes several refining processes to meet the standards of edible oil. These processes include degumming, decolorizing, and deodorizing. Briefly, degumming removes gums and phospholipids, decolorizing removes color pigments, and deodorizing removes unwanted odors and flavors.
  • 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).
