Oil from Rice Bran and its Processing Technology
In this technology, the cell tissue of rice bran is hydrolyzed with protease and then oil is released to achieve the purpose of oil extraction (Hanmoungjai et al. 2001). In a previous study, Chen (2014) used alkaline protease to extract oil from rice bran and determined the optimal process parameters.
1. Introduction. 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).
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 major prerequisite for processing the oil through physical refining is to have phosphorus content < 5 ppm for degummed, bleached, and dewaxed oil. Degumming is the key pretreatment process before physical refining, followed by bleaching and dewaxing. Because RBO is a dark-colored oil having waxes, special strategies are to be adopted even
Rice Bran and Rice Bran Oil
The addition of alkali reduces the micronutrient contents in refined oil. It is, therefore, evident that physical refining would be the preferred refining methodology for RBO. The major prerequisite for processing the oil through physical refining is to have phosphorus content < 5 ppm for degummed, bleached, and dewaxed oil. Degumming is the
A new process for the physical refining of rice bran oil through combined degumming and dewaxing was developed on a laboratory scale and then demonstrated on a commercial scale. The simultaneous degumming and dewaxing of the crude oil with a solution of water and CaCl2, followed by crystallization at a low temperature (20°C), facilitated precipitation of the hydratable and nonhydratable

The Journal of the American Oil Chemists' Society publishes original research and technological advances on fats, oils, oilseed proteins, and related materials. Abstract A new process for the physical refining of rice bran oil through combined degumming and dewaxing was developed on a laboratory scale and then demonstrated on a commercial scale.
Phytosterols and γ-oryzanol in rice bran oils and distillates
Summary Commercially available refined rice bran oil (RBO) contained high contents of phytosterol and γ-oryzanol, that is, 858–1034 and 248–887 mg per 100 g oil, respectively. Although the crude rice bran oil (CRBO) had high contents of both phytochemicals (1362–1376 mg phytosterol per 100 g and 1599–1666 mg γ-oryzanol per 100 g), physical refining process resulted in their reduction
Expand. 20. Physical refining of rice bran oil (RBO) with acidity between 4.0 and 12.4% has been investigated in relation to degumming and dewaxing pretretments. It appears that physical refining after combined low-temperature (10°C) degumming-dewaxing produces good-quality RBO with respect to color, free fatty acid, oryzanol, and tocopherol
- How is rice bran oil refined?
- After the extraction, the crude rice bran oil is often refined in order to improve its quality and commercial value. The fundamental steps of the refining process include dewaxing, degumming, neutralization of the free fatty acids, bleaching, and steam deodorization.
- What are the technologies of rice bran oil?
- 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.
- 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 deacidification of rice bran oil?
- Deacidification is the process of removing free fatty acids from crude rice bran oil. The deacidification methods of rice bran oil include alkali refining, distillation, mixing, re-esterification, and extraction. The alkali refining method has comprehensive effects such as deacidification and decolorization, but the refining loss is much higher.
