What is rice bran oil (RBO)?
This lipidic fraction can be extracted to obtain rice bran oil (RBO), a high value-added product with unique health properties as a result of its high concentration in ¦Ã-oryzanol, a powerful antioxidant mixture of bioactive molecules.
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 organic solvent extraction.
