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 (RBO)?
Rice bran oil (RBO) is considered to be a superior quality oil as it has a balanced fatty acid profile, and it contains a number of minor components with proven nutritional benefits such as γ-oryzanol, tocotrienol, tocopherol, and squalene (Houston, 1972 ).
Why is parboiled rice bran a good choice for dewaxing?
It was observed that oils obtained from parboiled rice bran have much easier operation compared to raw bran. The temperature of the place also has an influence on dewaxing parameters. Another important factor is the moisture content of the oil.
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.
