1, laxative: Carbohydrates in rice bran do not act with digestive enzymes in intestinal tract, thus playing the same laxative effect as adding wheat bran.

2, extracts the rice bran oil: Rice bran extracts the rice bran oil in our country already to get the larger development, because the rice bran oil mainly is the unsaturated fatty acid, but also contains the vitamin E, the squalene, the active lipase and the solid form phytoconstituent and so on. Rice bran oil can reduce the cholesterol in the blood vessel wall excessive deposition, can be used in the prevention and treatment of high blood fat. Rice bran oil is rich in 3 kinds of ferulic acid ester antioxidants play an important role in its antioxidant stability.

3, extract phytic acid: phytic acid in plants usually appears in the form of calcium phytate, calcium phytate content in rice bran can be up to 10%~11%, usually can be extracted by precipitation method or ion exchange method. After extraction of phytic acid from skimmed rice bran, the dregs can be used as feed with high nutritional value.

4, extract ferulic acid from rice bran, as food additives, with adsorption of ultraviolet light and prevent oxidation. The ceramide glycoside contained in the rice bran has the function of inhibiting the melanin generation, uses it to manufacture the cosmetic to keep the skin moist and white.

Hu Chengmiao, the executive director of China Cereals and Oils Society, said in June, 2012 at the first international exchange meeting of rice oil industry development: if we can reasonably utilize the rice bran resources, our country can produce more than 2,300,000 tons of rice oil every year, which is equivalent to the oil content of the soybeans produced by our country's more than 100,000,000 acres of land, which will make the edible oil self-sufficiency rate of our country increase by 5%. Edible oil self-sufficiency rate increased by 5 to 10 percent.

China is a big rice-producing country. in 2011, China's rice production amounted to as much as 200 million tons, while the amount of rice bran amounted to 18 million tons, and the oil content rate of rice bran was as high as 15 percent. "China has the natural advantage of promoting and popularizing rice oil. This is one of the effective ways to improve the self-sufficiency rate of China's edible oil without competing with grain for land, and a useful attempt to solve the problem of China's high dependence on foreign oilseeds.

Technological limitations are the main reason that the utilization rate of rice bran in China has been at a low level. National grain and oil industry science and technology innovation forerunner, created a decentralized preservation, centralized production, centralized refining "a decentralized, two centralized" new rice oil production mode, overcome the best preservation of rice skin and rice germ for only 6 hours of the problem, and effectively expand the production capacity.
