  • What is the preferred process for refining rice bran oil?
  • 3. Preferred Process for Refining of Rice Bran Oil 3.1. Physical Refining Versus Chemical Refining Fig. 1 shows the various stages of the physical and chemical refining processes. Physical refining of RBO includes four basic operations, namely degumming, bleaching, dewaxing, and deodorization/deacidification.
  • 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 γ-oryzanol, tocotrienol, tocopherol, and squalene (Houston, 1972).
  • 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.
  • 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%–20% of oil. Apart from oil, rice bran is a promising source for proteins, carbohydrates, dietary fiber, vitamins, tocopherol, γ-oryzanol, and phospholipids (Tao, 1989; Houston, 1972; Saunders, 1986).
