Processing Technology of Rice Bran Oil, ScienceDirect
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 ).
Components of rice bran oil have been assessed for their effect on refining losses. Rice bran oil used in the study had the following (percent) analysis: free fatty acids, 6.8; phosphatides, 1.25

why choose solvent extraction method to extract rice bran. due to the low oil content of rice bran, we choose the solvent extraction method to extract the rice bran oil mostly. rice bran oil is high nutritional value and more and more popular among the people, but the oil content of rice bran only 15-18%, it's lower than sunflower seed, corn germ, peanut, and so on.

Optimization of Physical Refining to Produce Rice Bran Oil
Crude rice bran oil (RBO) is rich in valuable minor components such as tocotrienols, phytosterols and γ-oryzanol. These compounds are well preserved during physical refining, but in current industrial practice, RBO is mostly refined chemically because this results in a lighter color. However this process removes most of the γ-oryzanol. The challenge is to develop a refining process which
Degumming. Rice Bran oil contain phosphatides like other oils 1.5% max. This will be removed through the standard degumming process by addition 2% water and 1kg to 1.5Kg of food grade phosphoric acid to the oil at 60°C and allowing to mix for 20 minutes and then by separating through the centrifugal separators.
Effects of Crude Rice Bran Oil Components on Alkali-Refining
The effects of minor components in crude rice bran oil (RBO) including free fatty acids (FFA), rice bran wax (RBW), γ-oryzanol, and long-chain fatty alcohols (LCFA), on alkali refining losses were determined. Refined palm oil (PO), soybean oil (SBO) and sunflower oil (SFO) were used as oil models to which minor component present in RBO were added. Refining losses of all model oils were
RBO, rice bran oil. Oryzanol is an important component of crude rice bran oil (RBO), and its content ranges from 1.5 to 2.9% in RBO (1). It has many beneficial biological effects. Some of the biological effects of oryzanol and RBO are: (i) reduction of cholesterol in the blood of experimental rats and human volunteers (2,3),
- How is crude rice bran oil refined?
- The refining process for crude rice bran oil typically begins with dewaxing or winterizing. This step is necessary due to the fact that crude rice bran oil can contain up to 8% wax, depending on the extraction method.
- What is deacidification of rice bran oil?
- Deacidification is the process of removing free fatty acids from crude rice bran oil. This process can be achieved through various methods such as alkali refining, distillation, mixing, re-esterification, and extraction. Among these, alkali refining has comprehensive effects like deacidification and decolorization, but it results in higher refining loss.
- What are the technologies of rice bran oil?
- The processing technologies of rice bran oil include degumming, deacidification, dewaxing, etc.. These technologies help refine the oil and maintain its bioactive compounds.
- What are the initial refining processes for rice bran oil?
- 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.
- Is rice bran chemically refined?
- In industrial practice, rice bran is still mostly chemically refined. Earlier attempts to apply physical refining failed because it was not possible to produce a refined oil with a sufficiently light color.
- What is rice bran oil?
- Rice bran oil (RBO) is unique among edible vegetable oils because of its unique fatty acid composition, phenolic compound (¦Ã-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.
