A novel process for physically refining rice bran oil
components present in rice bran oil are destroyed or removed during traditional alkali refining. Chemical refining of rice bran oil generally results in losses that are considerably higher than those encountered with other vegetable oils [3, 4]. These higher losses are attributed to the presence of larger amounts of FFA and nonoily constituents.

γ-Oryzanol and tocopherol contents in residues of rice
Rice bran, a by-product of rice processing, represents about 8–11% of the grain by weight, and contains 16–22% of lipids, thus being commonly used for rice bran oil (RBO) extraction (da Silva et al., 2006, Pestana et al., 2009). Refining is decisive for improving stability, quality (flavour and colour) and functionality (fatty acid composition, vitamins and antioxidants) of RBO.
