  • 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 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.
  • What is the chemical composition of rice bran?
  • Chemical composition of bran depends on rice variety, treatment of the grain prior to milling, milling technology used, degree of milling, and the downstream processing of bran, that is, fractionation. Typical oil content in rice bran varies between 10% and 23%. Genotype significantly affects the oil content in bran ( Goffman et al., 2003 ).
  • Is rice bran oil oxidation a stable product?
  • Rice Bran Oil Oxidation RBO is promoted as a stable product due to high concentrations of antioxidants, that is, oryzanol, tocopherols, and tocotrienols, naturally present in the oil ( Latha and Nasirullah, 2014; Mishra and Sharma, 2014 ).
