After that, the fatty acid composition, bioactive compounds, and the processing technologies of rice bran oil are described and the refining technology of rice bran oil (degumming, deacidification, dewaxing, etc.) as well as the technologies to remaining the bioactive compounds in rice bran oil are introduced.
How is rice bran oil processed?
The crude rice bran oil must go through a series of refining processes before it can meet the requirements of the standard of edible oil; those refining processes include degumming, decolorizing, and deodorizing (Haraldsson 1983 ), these processing are briefly described as follows.
How to make rice bran oil from rice husk?
When refers to Rice bran oil production, the following three processing steps are important they are raw material preparation, Rice bran oil extraction, and crude oil refining. Like other oil bearing materials, before making oil from rice husk, these raw materials must have been fully prepared.
What is rice bran?
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).
