Problems solved by technology

[0003] The rice bran mixture obtained by the traditional extrusion extruding process contains a small amount of broken rice, and broken rice is the main source of starch, wherein the weight percentage of broken rice in the rice bran mixture is greater than 40%, and the starch content in the rice bran powder made for this is high, The increase of starch content causes the relative content of other nutrients to decrease; the traditional extrusion extruding process uses high temperature above 100°C to treat rice bran, which will cause greater damage to nutrients sensitive to high temperature; the grinding and crushing of the traditional extrusion extruding process is to use General grinding machine, the product fineness is below 80 mesh, which is not conducive to the absorption of nutrients after eating

Embodiment 1

[0035] This embodiment is based on figure 1 Raw material rice was preliminarily processed as indicated, and Wugong black indica rice (purchased from Shanghai Shangnong Health Food Co., Ltd.) Brown and milled rice. Among them, dehusking is the process of removing the husks of paddy rice to obtain brown rice. Rice milling is the process of stripping the bran and grain of brown rice. However, a small amount of broken rice is mixed in the rice bran collected after peeling, and the rice bran containing a small amount of broken rice is called a rice bran mixture. It is then sieved using a vibrating sieve. The sieve hole size of the vibrating sieve is 20 mesh, and the rice bran or the rice bran mixture with a rice bran content of 70% is obtained through sieving. The vibrating screen is made of copper or stainless steel.

[0036] In this embodiment, the rice bran or the rice bran mixture is dried. The drying equipment is an electronic intelligent drying equipment that can contro...

Embodiment 2

[0042] This embodiment is based on figure 1 Raw material rice was preliminarily processed as indicated, and Wugong black indica rice (purchased from Shanghai Shangnong Health Food Co., Ltd.) Brown and milled rice. Among them, dehusking is the process of removing the husks of paddy rice to obtain brown rice. Rice milling is the process of peeling off the bran and grain of brown rice, but a small amount of broken rice is mixed in the rice bran collected after peeling, and the rice bran containing a small amount of broken rice is called a rice bran mixture. Then use a vibrating sieve to sieve. The mesh size of the vibrating sieve is 26 meshes, and the rice bran or the rice bran mixture with a rice bran content of 60% is obtained through sieving. The vibrating screen is made of copper or stainless steel.

[0043] In this embodiment, the rice bran or the rice bran mixture is dried. The drying equipment is an electronic intelligent drying equipment that can control temperature a...

Embodiment 3

[0049] The rice bran powder in this example is made from the rice bran of Wugong black indica brown rice and Wugong black japonica brown rice. The weight ratio of Ugon black indica rice bran and Ugon black japonica rice bran is 1:1. The resulting rice bran powder contained 7.4% (weight percent) anthocyanins. 10.6% (by weight) of the crude fiber in the original state remained in the rice bran powder. Rice bran powder also preserves 352mg / kg calcium, 71.1mg / kg iron, 58mg / kg zinc, 101mg / kg vitamin E and 1mg / kg vitamin B1. The content of total flavonoids in rice bran powder is 2510mg / kg. The starch content in the rice bran powder is 300 g / kg, the water content of the rice bran powder is 113 g / kg, and the fineness of the rice bran powder is below 200 mesh, preferably 200 mesh.

Abstract

The invention discloses a processing method for rice bran powder. The processing method comprises the following steps: (1) providing rice bran or a rice bran mixture, wherein the weight percentage ofthe rice bran in the rice bran mixture is 60% or above; (2) drying the rice bran or the rice bran mixture at a temperature of 100 DEG C or below; and (3) crushing the rice bran or the rice bran mixture so as to obtain the rice bran powder. The rice bran powder obtained by using the method provided by the invention has high anthocyanin content and rich cereal nutrients.

Description

technical field [0001] The invention relates to the technical field of food, in particular to a rice bran powder and a processing method thereof. Background technique [0002] Rice bran is composed of pericarp, seed coat, outer endosperm, aleurone layer and embryo in brown rice. The rice bran mix is ​​made up of rice bran and a small amount of broken rice. Rice bran is rich in various nutrients and bioactive substances. Now in developed countries such as the United States, edible rice bran has come out, and similar products have been invented in China. Now the market is full of various rice bran powders. Rice bran powder has the effect of laxative, lowering cholesterol and reducing urinary stones. It is a long-term consumption Healthy food. However, due to the different raw materials and processing techniques used for processing rice bran, the composition of rice bran is not exactly the same. [0003] The rice bran mixture obtained by the traditional extrusion extruding ...
