Method for preparing soluble dietary fibers of bean dregs

Abstract

The invention provides a method for preparing soluble dietary fibers of bean dregs, which solves the problems of low yield and high cost of the soluble dietary fibers of the bean dregs in the prior art. According to the method, mechanical, chemical and enzyme methods are creatively combined, so compared with the conventional single or two-method combined preparation method, the method has the advantages of high product yield, high quality and low cost; the sequence is a continuous operating process, and the three kinds of treatment is sequential and synergetic; and the method has the greatest significance that the yield and the quality of the soluble dietary fibers in the bean dregs are improved, and the yield is improved by 42 to 43.8 percent. The method is simple, easy to operate and short in period, and does not require complex equipment. In the double-screw extrusion process, the conventional thought of high-temperature extrusion is broken, and an extrusion mode of low temperature and high shear is utilized; and cellulose, xylanase and pectinase are creatively combined and used in a specific ratio and used for preparing the soluble dietary fibers of the bean dregs together to achieve a good effect.

Description

technical field [0001] The invention provides a method for preparing soybean dregs soluble dietary fiber, relates to a soybean dietary fiber processing technology, and belongs to the technical field of food processing. Background technique [0002] As a functional food base material, dietary fiber is widely used in the food industry and has become the seventh largest nutrient after sugar, protein, fat, water, minerals and vitamins. According to the different solubility of dietary fiber, it can be divided into soluble dietary fiber (soluble dietary fiber, SDF) and insoluble dietary fiber (insoluble dietary fiber, IDF). Cellulose, lignin. Many studies have shown that SDF has stronger physiological functions than IDF in many aspects, and its application range is wider than IDF. However, most of the dietary fiber from natural sources is IDF, and the content of SDF is relatively low. Therefore, it is particularly important to increase the content of SDF in natural dietary fiber...
