Rice bran oil (RBO) is obtained through extraction of rice bran which is a by-product of the rice milling industries. There are several techniques used for the extraction of the RBO, but solvent extraction using hexane is the most popular used conventional method for commercial extraction.
How is RBO extracted from rice bran?
The Japanese were the first to extract RBO from rice bran using the hydraulic press technique, which is still used nowa-days, but recently, the preferred industrial technique for com-mercial uses is extraction using non-polar solvents, such as hexane .
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 -γ oryzanol, a powerful antioxidant mixture of bioactive molecules.
What is rice bran oil?
Rice bran oil (RBO) is unique among edible vegetable oils because of its unique fatty acid composition, phenolic compound (γ-oryzanol, ferulic acid) and vitamin E (tocopherol and tocotrienol). It has become a great choice of cooking oil because of its very high burning point, neutral taste and delicate flavour.
