Method for retaining polyphenol content in rice milling process

The invention discloses a method for retaining the polyphenol content in the rice milling process. The method comprises the following steps that A, brown rice obtained from decladding of rice seeds ismechanically milled; and B, the product obtained after the treatment of the step A is crushed and screened, and rice flour with the high retaining rate of polyphenol is obtained. By means of the method, through precise control of the milling rotary speed and time, milling is conducted, and meanwhile, the polyphenol content in the rice flour is effectively retained; and the method is simple in operation, the process is safe and efficient, the obtained rice flour can be used as a novel healthy food, the product has antioxidant and anti-free radical ability, the platelet coagulation can be inhibited, the incidence of coronary heart diseases and cancers is reduced, the tissue aging is delayed, the good effect is achieved, and the rice flour is the ideal choice for the patients with cardiovascular and cerebrovascular
