Embodiment 1

[0020] A kind of production method of purple sweet potato dregs dietary fiber mainly adopts the following steps:

[0021] A. Raw material pretreatment: crush purple sweet potato dregs and red sweet potato dregs, the weight ratio of purple sweet potato dregs and red sweet potato dregs is 1:1, the crushing particle size is 40 mesh, and then add purple sweet potato dregs and red sweet potato dregs 10 times the weight After fully stirring, let it stand for 3.5 hours to remove the potato skins and sundries floating on the upper layer;

[0022] B. Starch gelatinization, hydrolysis, and saccharification: the purple sweet potato dregs and red sweet potato dregs after impurity removal treatment are kept at 85°C for 30-40 minutes, and the purple sweet potato dregs and red sweet potato dregs are first gelatinized, and then cooled to 62°C , add α-amylase to hydrolyze for 1-2 hours according to the weight of purple sweet potato dregs and red sweet potato dregs, cool the material after enzy...

Embodiment 2

[0031] A kind of production method of purple sweet potato dregs dietary fiber mainly adopts the following steps:

[0032] A, raw material pretreatment: crush purple sweet potato residue and potato residue, the weight ratio of purple sweet potato residue and potato residue is 2:1, and the crushing particle size is 35 mesh, then add purple sweet potato residue and potato residue 10 times the weight of water, After fully stirring, let it stand for 3.5 hours to remove the purple sweet potato skin, potato skin and sundries floating on the upper layer;

[0033] B. Starch gelatinization, hydrolysis, and saccharification: the purple sweet potato dregs and potato dregs after impurity removal treatment are kept at 85°C for 38 minutes, and the purple sweet potato dregs and potato dregs are first gelatinized, and then cooled to 65°C, press purple sweet potato Add α-amylase to hydrolyze 1% of the weight of dregs and potato dregs for 2 hours, cool down the enzymatically hydrolyzed material ...

Embodiment 3

[0042] A kind of production method of purple sweet potato dregs dietary fiber mainly adopts the following steps:

[0043] A. Raw material pretreatment: crush purple sweet potato dregs and bean dregs, the weight ratio of purple sweet potato dregs and bean dregs is 3:1, the crushing particle size is 40 mesh, then add water 9 times the weight of purple sweet potato dregs and bean dregs, and stir well Let it stand for 4 hours, remove the purple sweet potato skin, soybean skin and sundries floating on the upper layer;

[0044] B. Starch gelatinization, hydrolysis, and saccharification: the purple sweet potato dregs and bean dregs after impurity removal treatment are kept at 85°C for 35 minutes, and the purple sweet potato dregs and bean dregs starch are gelatinized first, and then cooled to 65°C. Add α-amylase to hydrolyze 1.3% of the weight of bean dregs for 2 hours, cool the material after enzymolysis to 60°C, adjust the pH value to 5.5, add glucoamylase to 1% of the weight of th...

Abstract

The invention provides a production method of purple sweet potato residue dietary fibers, relates to the field of dietary fiber processing. The dietary fibers are processed from purple sweet potato residues, and the dietary fiber product quality is improved by the process of thinning purple sweet potato residue particles, homogenizing, performing high-pressure spray-drying and the like. According to the method, the purple sweet potato residues are used as a raw material for processing the purple sweet potato residue dietary fibers; the purpose of turning wastes into wealth is achieved; a product is rich in dietary fibers and good in quality, and can promote gastrointestinal motility, remove mucus, intestinal gas and septic matter retained in an enteric cavity, discharge toxic substances and cancerogenic substances in excrement, improve a digestive tract environment and prevent gastrointestinal diseases after being eaten often. A new path is opened for comprehensive development and utilization of potato residues and bean dregs, an environment protection effect is achieved, and the production method has high economic and beneficial benefits.

Description

technical field [0001] The invention relates to a processing method of dietary fiber, in particular to a production method of purple sweet potato dregs dietary fiber. Background technique [0002] Purple sweet potato is rich in protein, 18 kinds of amino acids that are easily digested and absorbed by the human body, 8 kinds of vitamins such as vitamin C, B, and A, and more than 10 kinds of natural mineral elements such as phosphorus and iron. It is rich in iron and selenium. Selenium and iron are essential elements for anti-fatigue, anti-aging, and blood enrichment. They can enhance the body's immunity, remove free radicals in the body, inhibit the synthesis of DNA in cancer cells and the division and growth of cancer cells, and prevent cancers such as gastric cancer and liver cancer. happened. [0003] Purple sweet potato is rich in plant cellulose, and purple sweet potato residue is a high-quality dietary fiber, which can promote gastrointestinal motility, clean up mucus...
