Abstract
In as much as the oryzanol can be efficiently recovered from rice bran oil, two processes using an anion exchange resin were investigated. In the first process, oryzanol and free fatty acid adsorbed by resin were simultaneously desorbed with the mixture of benzene, methanol and hydrochloric acid (or acetic acid gracial, boric acid etc.) solution from which oryzanol was recovered with good result. In the second, oryzanol was separately adsorbed by the resin esterifying the free fatty acid and then oryzanol was desorbed and recovered with the same mixed solution. Both processes are recommended as practical.
