  • What is rice bran?
  • Rice bran is obtained from outer layer of the brown (husked) rice kernel during milling. It has emerged as potential by-product from rice processing industry due to the increasing demand for rice bran oil (RBO) as healthy functional food ingredients.
  • Is rice bran oil a seed derived oil?
  • Rice bran oil (RBO) is not a seed-derived oil. Therefore, the crude oil obtained by conventional solvent extraction using hexane has a number of impurities that are required to be removed before human consumption. Unlike other oils, the bran contains a lipase enzyme that converts the neutral oil to free fatty acids (FFAs) and partial glycerides.
  • What is rice bran oil (RBO)?
  • Rice bran oil (RBO) is considered to be a superior quality oil as it has a balanced fatty acid profile, and it contains a number of minor components with proven nutritional benefits such as ¦Ã-oryzanol, tocotrienol, tocopherol, and squalene (Houston, 1972).
  • Should rice bran be stabilized after production?
  • It is advised to stabilize rice bran or RBO immediately upon production. High FFA results in high refining loss, therefore, it is beneficial to have FFA level of less than 5% in the crude RBO, and exceeding amount of FFA (> 10%) is unfit for human consumption (Orthoefer and Eastman, 2005).
  • When should oil be extracted from rice bran?
  • 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. Under favorable conditions, the rate of oil degradation and FFA formation could be very high (Houston, 1972).
  • What is degumming of rice bran oil?
  • Degumming of Rice Bran Oil The most important pretreatment step is the degumming of crude oil. Oil degumming is carried out to remove undesired phospholipids, metal ions, and other impurities from oil.
