Rice Bran Oil: A Versatile Source for Edible and Industrial

Trends of Ricebran Oil production in Zimbabwe Tridge

  • 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 used for?
  • This by-product represents around 9% of all milled rice, and it is full of nutritional and bioactive compounds, but despite these positive proprieties, it is usually wasted or used for animal feeds. Rice bran is particularly rich in oil, which is generally extracted by means of mechanical pressing or or-ganic solvent extraction.
  • What is commercial rice bran?
  • Commercial rice bran is usually a mixture of these two rice by-products . This fraction possesses an extraordinary quantity of nutritive compounds, such as fibers, fats, proteins, vitamins (vitamin E and B complexes), and antioxidant mol-ecules. It contains 10 –23% of oil, which is usually extracted using a solvent .
  • Which solvent is used in rice bran oil extraction?
  • The solvents applied in the extraction processes are generally organic compounds derived from non-renewable sources . Hexane is the most common solvent used in rice bran oil extraction . This solvent is cheap and efficient, but it is a petroleum-based solvent, volatile, flammable, and dangerous for humans and for the environment .
