  • How does rice bran oil affect refining?
  • Solvent extracted rice bran oil contains considerable amounts of phosphatides and other mucilaginous materials which form deposits in the storage tanks. They, in combination with oryzanol, increase refining losses by emulsifying considerable amounts of neutral oil, which is lost in the soap stock.
  • What is rice bran?
  • Rice bran is a byproduct of the rice milling industry obtained from milling of brown rice to produce white rice. It contains 15%¨C20% of oil. Apart from oil, rice bran is a promising source for proteins, carbohydrates, dietary fiber, vitamins, tocopherol, ¦Ã-oryzanol, and phospholipids (Tao, 1989; Houston, 1972; Saunders, 1986).
  • 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.
  • 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.
  • Is rice bran chemically refined?
  • In industrial practice, rice bran is still mostly chemically refined. Earlier attempts to apply physical refining failed because it was not possible to produce a refined oil with a sufficiently light color.
  • What is rice bran wax used for?
  • Some industrial manufacturers also used it for oil recovery. However, the recovered oil was utilized for nonedible applications. In addition, a few researchers (Prasad et al., 2008, Prasad et al., 2009) developed a process for the upgradation and bleaching of crude rice bran wax.
