Abstract

The invention discloses a preparation method of a wheat bran dietary fiber. The preparation method includes the steps of: pretreatment, production of a semi-product, purification, and post-treatment. The invention also discloses the wheat bran dietary fiber produced through the method. In the pretreatment, a wheat bran raw material is subjected to high-temperature steaming, steam explosion and ultrasonic treatment in a combination manner, so that the structure and tissue of the raw material are effectively damaged and inclusions are completely exposed; by means of impurity removal treatment, content of non-dietary fiber components in the raw material is reduced. After the pretreatment, enzymolysis effect with cellulase or a compound enzyme including cellulase and hemicellulase is increased, so that enzymolysis is more completely and the purity of the product is increased, in addition, the palatability of the product is improved; after the enzymolysis, purification is carried out to further increase the purity, so that the product is high in purity; the wheat bran dietary fiber has small fiber particle size and has high water retention capability and expansion property.

Description

technical field [0001] The invention belongs to the technical field of dietary fiber preparation, and in particular relates to a preparation method of wheat bran dietary fiber and the wheat bran dietary fiber. Background technique [0002] Dietary fiber is an important non-nutrient. It is a kind of indigestible part of carbohydrates such as non-starch polysaccharides and oligosaccharides. It can neither be digested and absorbed by the human gastrointestinal tract, nor can it produce energy. However, in recent years, more and more studies have shown that the intake of dietary fiber is closely related to human health, and adequate intake of dietary fiber will reduce the risk of constipation, obesity, diabetes, cardiovascular disease and intestinal cancer. For example, dietary fiber can absorb a large amount of water in the intestinal tract, keep the stool soft, effectively activate the beneficial bacteria in the intestinal tract, promote the proliferation of beneficial bacteri...
