  • 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).
  • 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.
  • What are the steps in a rice bran oil refining process?
  • The steps in the process of refining rice bran oil are given in Fig. 14.1. The first step in the refining process with crude rice bran oil is usually dewaxing or winterizing. However, for other vegetable oils, the dewaxing step can be done at different times in the refining process.
  • Is -oryzanol a value-added co-product of rice bran processing?
  • ¦Ã-Oryzanol is an important value-added co-product of rice bran processing. Therefore, research to improve the recovery of ¦Ã-oryzanol and other phytochemicals, in order to obtain fractions enriched in a particular compound or group of compounds, has been conducted.
  • 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.
  • Where is rice bran oil primarily used?
  • Rice bran oil is primarily used in Japan and India, and to a certain extent in other parts of Southeast Asia, such as Thailand and Indonesia.
