Rice bran is a byproduct of the rice milling industry obtained from milling of brown rice to produce white rice. It contains 15%?20% of oil. Apart from oil, rice bran is a promising source for proteins, carbohydrates, dietary fiber, vitamins, tocopherol, γ-oryzanol, and phospholipids ( Tao, 1989; Houston, 1972; Saunders, 1986 ).
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.
What is rice bran wax used for?
Some industrial manufacturers also used it for oil recovery. However, the recovered oil was utilized for nonedible applications. In addition, a few researchers ( Prasad et al., 2008, Prasad et al., 2009) developed a process for the upgradation and bleaching of crude rice bran wax.
How to stabilize rice bran?
The results indicated that microwave, extrusion, steaming, -80 °C, ultraviolet irradiation, infrared heating have potential to stabilize rice bran. Extrusion and microwave processes are suitable for large-scale with short-time industrial processing although with increase of oil peroxide values and colour.
