Abstract

The invention discloses a preparation method of bean dreg dietary fiber. The preparation method of the bean dreg dietary fiber comprises the following steps of carrying out pretreatment, preparing semi-finished products, carrying out purification, and carrying out post-treatment. The invention further discloses bean dreg dietary fiber prepared according to the preparation method of the bean dreg dietary fiber. According to the preparation method of the bean dreg dietary fiber, a combination of a high-temperature steaming treatment, a steam explosion treatment and an ultrasonic treatment is adopted when pretreatment is performed on raw materials so as to effectively destroy structural organizations of the raw materials, and thus, inclusions in the raw materials are fully exposed; moreover,impurity removing treatment is combined so as to further reduce non-dietary-fiber components in the raw materials. The pretreated raw materials are beneficial for enhancement of enzymatic hydrolysis effects of cellulase or compound enzymes of cellulase and hemicellulase so as to ensure more sufficient enzymatic hydrolysis, and thus, purity of final products is improved; moreover, palatability of the final products can be also effectively improved. In addition, purification is further carried out after the enzymatic hydrolysis so that the purity is further increased, and thus, the final products have the advantage of high purity. The bean dreg dietary fiber disclosed by the invention further has the advantages of small fiber particle size, strong water holding capacity, and high in expansive capacity.

Description

technical field [0001] The invention belongs to the technical field of dietary fiber preparation, and in particular relates to a preparation method of okara dietary fiber and okara 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 bacteria, and create ...
