Problems solved by technology

The existing oil bran is usually used as feed, feed additive, and fishing bait, and the economic benefit is not high
Especially the oil bran of purple rice and black rice is rich in natural anthocyanins, and directly used as a feed additive or fishing bait seriously reduces its economic value

Abstract

The invention provides a preparation method of wheat meal containing abundant natural anthocyanin for solving the problems in the prior art. The method comprises the steps that S1, oil bran of rice containing abundant natural anthocyanin is selected, and puffing oil bran is prepared; S2, the puffing oil bran obtained in S1 is smashed into 100-120 meshes, and oil bran powder is obtained; S3, the oil bran powder obtained in S2 and wheat meal are mixed according to a preset ratio, and wheat meal containing abundant natural anthocyanin is obtained. The oil bran of rice containing natural anthocyanin in step 1 is pulp rice oil bran or black rice oil bran or the mixture of the pulp rice oil bran and the black rice oil bran. The oil bran of rice containing natural anthocyanin is subjected to deepprocessing treatment, and the economic value of the pulp rice oil bran and the black rice oil bran is increased. Meanwhile, the unique oil bran puffing treatment technology is adopted, and the effective ingredient content of natural anthocyanin is reserved to the maximum extent in the puffing process.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a wheat flour rich in natural anthocyanins and a preparation method thereof. Background technique [0002] Wheat is the general name of wheat plants. It is a monocotyledonous plant and a gramineous plant widely planted all over the world. The caryopsis of wheat is one of the staple foods of human beings. After being ground into flour, it can be used to make bread, steamed buns, biscuits, and noodles. Food such as fermented can be made into beer, alcohol, liquor (such as vodka), or biomass fuel. Wheat is one of the three major grains, and almost all of it is used for food, and only about one-sixth is used as feed. Mesopotamia is the first area in the world to cultivate wheat, and China is one of the earliest countries in the world to plant wheat. [0003] Wheat can be divided into white wheat and red wheat according to the color of the skin. White-skinned wh...
