Problems solved by technology

Although the yield of oligosaccharides can be increased after enzymatic hydrolysis, it is difficult for the remaining phytic acid, starch, monosaccharides, disaccharides, phenolic acids, proteins, flavonoids, and lignans to effectively decompose the oligosaccharides after filtration and decolorization. Sugar is separated from them; the biggest weakness of ion exchange is low efficiency and long time, so the industrialization technology of bran oligosaccharides is still in the laboratory research stage
This has hindered the industrial application of bran oligosaccharides

Embodiment Construction

[0028] According to a preferred embodiment of the present invention, the production process of wheat bran soluble oligosaccharides is as follows: bran → pulverization → homogenization → paste mixing → one-step enzymatic hydrolysis with compound enzyme → separation and filtration → ethanol precipitation → reconstitution with water → three Deproteinize with chloroacetic acid → centrifuge → clear night → concentrate for later use, and finally obtain the bran oligosaccharide concentrate.

[0029] In a specific embodiment realizing above-mentioned production technique, comprise the following steps:

[0030] After drying and crushing the wheat bran, pass through a 60-mesh sieve;

[0031] Add 2-3 times deionized water to the crushed wheat bran;

[0032] Heating at 50°C for 20-30 minutes;

[0033] Homogeneous under 25-35Mpa pressure;

[0034] Under the condition of 45-55°C, add a compound enzyme preparation including phytase, cellulase, protease, amylase and oligosaccharide enzyme,...

Abstract

The invention refers to a method of producing oligose by wheat bran and the drink with the oligose. The method includes: dry the wheat bran and then crust; add in deionized water to drip; make homogeneous process; adds in the compound enzyme preparation including phytase, fibrin enzyme, protease and oligosaccharidase to make enzymolysis and adjust pH; making sterilization; centrifuge and filter to get the clear liquid with oligose; make vacu9um concentration on the clear liquid to get the concentrated mixture with dissoluble oligose soild. The components' dosage in the compound enzyme preparation: phytase 10-30 U / g bran, fibrin enuzyme 10-20 U / g bran, protease 30-40 U / g bran and oligosaccharidase 20-30U / g bran.

Description

technical field [0001] The present invention relates to a method for producing oligosaccharides and beverages containing the oligosaccharides produced by the method, in particular to a method for producing oligosaccharides from wheat bran and beverages containing the oligosaccharides produced by the method. Background technique [0002] At present, the amount of bran, a by-product of wheat processing, is as high as 20 million tons per year in my country. The utilization of bran is mainly used as livestock feed and fermentation medium. Therefore, the price is low. It is of great economic and social benefit to find an effective way to utilize bran and increase the utilization value of bran. The main component of bran is carbohydrates, accounting for about 60%. The development of functional oligosaccharides from bran carbohydrates is one of the effective ways to increase the value and comprehensive utilization of bran. [0003] The unique nutrition of wheat bran oligosacchari...
