  • How is rice bran oil refined?
  • After the extraction, the crude rice bran oil is often refined in order to improve its quality and commercial value. The fundamental steps of the refining process include dewaxing, degumming, neutralization of the free fatty acids, bleaching, and steam deodorization.
  • What is the largest oil refinery in South Africa?
  • Operated by the Port Harcourt Refining Company ¨C a subsidiary of the Nigerian National Petroleum Corporation ¨C the refinery is currently the country¡¯s largest operating refinery. South Africa¡¯s SAPREF refinery, a 50:50 joint venture between BP and Shell, is the largest crude oil refinery in southern Africa, boasting 180,000 bpd capacity.
  • 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 the preferred refining method for RBO?
  • The addition of alkali reduces the micronutrient contents in refined oil. It is, therefore, evident that physical refining would be the preferred refining methodology for RBO. The major prerequisite for processing the oil through physical refining is to have phosphorus content < 5 ppm for degummed, bleached, and dewaxed oil.
  • 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).
  • 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).
