Example Embodiment

[0032] Example 1:

[0033] A wheat flour containing a wheat aleurone layer, the wheat flour containing an aleurone layer of 3.8 wt%.

[0034] The preparation method of wheat flour with wheat aleurone layer includes the following steps:

[0035] 1) Light peeling

[0036] The wheat was lightly peeled, and the phloem layer, which accounted for 5.5% of the wheat mass, was peeled off. The skin of the wheat was effectively peeled off, and the wheat ditch was also effectively removed to obtain the wheat kernels with an aleurone layer;

[0037] 2) Tempering wheat

[0038] 3) Stripping of the aleurone layer

[0039] The wheat grains with the aleurone layer are sieved through a sieve with different meshes to extract the wheat aleurone layer;

[0040] 4) Smash and add back

[0041] The aleurone layer is superfinely pulverized, and the pulverized materials evenly enter the inspection sieve for screening, and then add back to the flour. Among them, the ultra-powder pulverization uses the existi...

Abstract

The invention discloses a preparation method of wheat flour containing a wheat aleurone layer. The preparation method comprises the following steps: slightly removing a phloem layer accounting for 5.5%-6% by mass of wheat from the wheat to obtain wheat grains with the wheat aleurone layer; screening the wheat grains with the wheat aleurone layer by sieves with different mesh numbers to extract the wheat aleurone layer; performing superfine grinding on the aleurone layer by adopting a superfine grinding technology, uniformly feeding the ground materials into a check sieve for screening, and adding the screened materials into the flour. According to the preparation method, a novel peeling technology, the superfine grinding technology and a wheat aleurone layer extracting and adding technology are organically combined, and the aleurone layer is applied to the flour industry, so that the nutritional element content of the flour is relatively high and the requirements of people are met.

Description

Technical field [0001] The present invention involves a kind of wheat flour and its preparation process, which specifically involves the extraction process of a wheat flour layer. Background technique [0002] Wheat paste layer is a special component in wheat seeds. It is rich in protein, lipids, minerals and other nutrients and has special physiological functions.The wheat paste layer does not have color, and the pink color does not have an impact. However, it is difficult to separate the paste layer from the surface of the surface of the flue pink in the modern flour industry.Remove the bran, and its various nutrients and physiological functions are worthy of effective use. [0003] Wheat paste layer is composed of a large number of thick wall cells, which is rich in B vitamins, minerals, and protein.When the flour with high grinding accuracy, the traditional flour processing paste layer will be removed with bran.According to the characteristics of the inherent tissue structure...
