  • What are the refining processes of rice bran oil?
  • The refining technology of rice bran oil includes degumming, deacidification, dewaxing, etc. as well as the technologies to remaining the bioactive compounds in rice bran oil.
  • What is rice bran oil?
  • This oil can be extracted from a byproduct (rice bran) of rice processing, and the production of this oil is gaining world-wide attention because of its interesting technological properties such as the excellent heat stability and high smoke point.
  • 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.
  • What is the difference between mixed refining and re-esterification of rice bran oil?
  • Mixed refining improves the refining rate and obtains high-quality rice bran oil with reduced solvent loss. On the other hand, re-esterification effectively removes free fatty acids and significantly increases the glycerol content in rice bran oil.
  • What is deacidification of rice bran oil?
  • Deacidification is the process of removing free fatty acids from crude rice bran oil. This process can be achieved through various methods such as alkali refining, distillation, mixing, re-esterification, and extraction. Among these, alkali refining has comprehensive effects like deacidification and decolorization, but it results in higher refining loss.
  • What is the acid value of rice bran oil after alkali refining?
  • After alkali refining, the oleic acid value of rice bran oil was reduced to 0.23 mg/g. Additionally, the extraction method also has a good effect on deacidification. Liu (2005) obtained rice bran oil with an acid value reduced from 31.02 to 4.52 mg/g at the ratio of oil to solvent (95% ethanol) of 1:1.8.
