Embodiment 1

[0049] The method for utilizing mulberry stalks and kudzu vines to produce dietary fiber comprises the following steps:

[0050] (1), first remove the soil, stones and sundries in the mulberry stalks, then crush the mulberry stalks to 3mm with a pulverizer; then use a double-screw extruder to puff the mulberry stalks to obtain mulberry stalk powder;

[0051] (2) After removing impurities from the kudzu vine, wash it, dry it in the shade, and crush it into a 100-mesh fine powder with a pulverizer;

[0052] (3) Weigh parts by weight of the mulberry stalk powder obtained after the puffing treatment in step (1), kudzu vine, bean curd residue and wheat bran pulverized in step (2) to obtain a mixture; add water twice the volume of the mixture , to obtain a slurry; put the slurry into -35°C for 25min / L and take it out; then thaw it at 10°C for 30min / L to obtain the broken slurry;

[0053] (4) Stir the wall-broken slurry obtained in step (3) evenly and put it into a cooking pot, add ...

Abstract

The invention discloses a method for producing dietary fibers by using mulberry twigs and kudzu vines. The method comprises the steps: firstly, cutting off the mulberry twigs, carrying out swelling treatment, then, mixing materials, and then, adopting a freezing wall breaking method to subject water liquid inside cells to icing expansion and break plant cell walls without damage dietary fibers, vitamins and other nutrient elements in the cell walls; then, introducing high-temperature steam, so as to subject part of free starch to pasting, carry out sterilization and contribute to the decomposition and removal of the starch in subsequent processes; then, imitating the pH value of a digestion environment by an acidic pH adjuster and an alkaline pH adjuster by using a semi-bionic method, softening the fibers so as to obtain relatively pure softened crude dietary fiber residues, and finally, carrying out bleaching, drying and ultramicro crushing processes, thereby preparing high-quality water-insoluble dietary fiber powder, of which the mass content is 60% to 65%.

Description

technical field [0001] The invention relates to a dietary fiber, in particular to a method for producing dietary fiber by utilizing mulberry stalks and kudzu vines. Background technique [0002] Dietary fiber usually refers to the part of plant food that cannot be digested and absorbed by the human body. A number of scientific studies in recent years have shown that the occurrence of many diseases is related to the lack of dietary fiber, which makes dietary fiber emerge. As human beings eat more and more finely, dietary fiber is more and more favored by people. [0003] According to the chemical structure, dietary fiber is divided into four categories: cellulose, hemicellulose, lignin and pectin. They cannot be absorbed by the human body but play important functions in the body and play the role of health guard. Dietary fiber can stimulate intestinal peristalsis, increase the volume of intestinal content, and reduce the time that feces stay in the intestinal tract. Dietar...
