rice bran oil extraction

Rice Bran Oil Extraction

Then rice bran solvent extraction is used to extract oil from rice bran. Advanced extraction technology and techniques were developed with technical assistance to come up with crude rice bran oil that is high in vitamin E and oryzanol.

Rice bran has 17% oil content by weight. After the refining process, the refined rice bran oil weighs only 12% of the rice bran raw material. Rice bran oil (also known as rice bran extract) is the oil extracted from the germ and inner husk of rice. It is notable for its very high smoke point of 490 °F (254 °C) and its mild flavor, making it suitable for high-temperature cooking methods such as stir frying and deep frying. It is popular as a cooking oil in several Asian countries, including Japan and China.

Rice Bran Oil Extraction

The bran fraction, which includes the germ or embryo in most commercial milling operations, represents only about 8% of paddy weight but contains about three-fourths of the total oil (Juliano and Bechtel, 1985; Lu and Luh, 1991). Containing about 15-20% oil (the same general range of soybeans), rice bran is commercially feasible for rice bran oil extraction.

Rice Bran Oil Extraction Process

The rice bran oil extraction process begins with raw material preparation. Rice bran is first screened and then heated by steam at temperature higher than 100 degrees Celsius to stop Lipase hydrolysis in rice bran prior to extraction.
