Embodiment 1

[0024] This embodiment includes the following steps:

[0025] (1) Raw material selection: wheat bran;

[0026] (2) Cleaning to remove impurities: put the wheat bran in a clear water tank for cleaning to remove impurities in the wheat bran;

[0027] (3) High-temperature cooking: put the cleaned wheat bran into a high-pressure cooking pot, add water in a weight ratio of 1:2 of wheat bran:water, then seal and heat to 121° C., and heat for 10-20 minutes;

[0028] (4) Phytic acid removal: cool the mixed solution after high-temperature cooking to 50-60°C, then add water until the weight ratio of wheat bran (dried wheat bran in step (1)) to water is 1:5, use 5 -10 mol / L of sulfuric acid to adjust the pH value of the mixture to 5.0, and maintain it for 5-6 hours to fully decompose the phytic acid;

[0029] (5) Hydrolysis: maintain the temperature of the phytic acid-removing mixture at 60° C., adjust the pH value to 6.0 with NaOH, add 2% neutral protease by the total weight of the li...

Embodiment 2

[0038] In the present embodiment, from raw material selection to bleaching, neutralization process is identical with embodiment 1, and difference is that its follow-up process adopts following method:

[0039] Dehydration: Put the decolorized and rinsed wheat bran fiber into the centrifuge for high-speed centrifugal dehydration to obtain hydrated dietary fiber;

[0040] Drying: Put the preliminarily dehydrated dietary fiber into a tray, put it into a vacuum drying oven, and carry out vacuum drying under the condition of a vacuum degree of 0.06MPa, and the drying temperature is 70-80°C;

[0041] Pulverizing and sieving: the vacuum-dried dietary fiber is ultrafinely pulverized and sieved with a superfine pulverizer to reach more than 120 mesh;

[0042] Inspection and packaging: The fineness and color of the refined dietary fiber after ultrafine grinding are inspected, and then quantitative packaging is carried out.

Abstract

A process for preparing edible bran fibres from wheat bran includes such steps as washing wheat bran, removing impurities, high-temp steaming, removing humic acid, hydrolyzing, enzymolyzing, deactivating enzyme, bleaching, neutralizing, and packing.

Description

technical field [0001] The invention relates to a method for extracting dietary fiber, in particular to a method for extracting dietary fiber from wheat bran, that is, a method for converting wheat bran into dietary fiber through multiple functions. Background technique [0002] Dietary fiber is suitable for all kinds of foods such as flour products, health food, fiber-fortified food, medical food and functional sports drink. There are: [0003] (1) Strong water absorption and expansion, low heat energy, can prevent obesity; [0004] (2) It can stimulate gastrointestinal motility, prevent constipation and intestinal system diseases; [0005] (3) It can absorb organic substances in the body, lower serum cholesterol, and prevent coronary heart disease caused by coronary arteriosclerosis; [0006] (4) It can accelerate the excretion of toxic metal ions through ion exchange, and play a role in detoxification and lowering blood pressure; [0007] (5) Regulate glucose metaboli...
