specific Embodiment 1

[0025] A preparation method rich in dietary fiber xylo-oligosaccharide powder, it comprises the following steps:

[0026] a) Bamboo raw materials are pretreated, cooked, pulp washed, enzymatically hydrolyzed for the first time, and separated and cleaned to obtain sugar liquid and fiber slag. The method of enzymatic hydrolysis for the first time is: , adding an appropriate amount of water to the extract after pulp washing, and then adding acid, so that the pH value of the first mixed solution is controlled at 3; second, the temperature is raised, so that the temperature of the first mixed solution is controlled at 30 ° C; third, Add enzymes, add an appropriate amount of amylase or xylanase to the first mixed solution, and the content of the amylase or xylanase is controlled at 0.2%; fourth, constant temperature, so that the first mixed solution is in a constant temperature environment, and its control The time is 3 hours; fifth, the temperature is raised so that the temperature...

Abstract

A preparation method for a xylooligosaccharide powder rich in dietary fibers comprises the following steps: carrying out pretreatment, cooking treatment, pulp washing treatment, first enzymolysis treatment and separation and cleaning treatment of a bamboo raw material successively, to obtain a sugar liquid and a fiber residue; carrying out refined purification and concentration treatment of the sugar liquid, to obtain a refined sugar liquid; carrying out secondary enzymolysis treatment, rinsing treatment and drying treatment of the fiber residue successively, to obtain a dried fiber, wherein the water content of the dried fiber is controlled at 0.5%-20%; mixing the refined sugar liquid and the dried fiber, to obtain a mixed slurry, wherein the mixing ratio of the refined sugar liquid to the dried fiber is (100-1):(30-80); and carrying out drying treatment of the mixed slurry to obtain the xylooligosaccharide powder. The prepared xylooligosaccharide powder rich in the dietary fibers canrelieve the characteristic of moisture absorption of xylooligosaccharide, and is convenient to use.

Description

technical field [0001] The invention relates to a preparation method of xylo-oligosaccharide powder, in particular to a preparation method of xylo-oligosaccharide powder rich in dietary fiber. Background technique [0002] Xylooligosaccharides, also known as xylooligosaccharides, are functional polymeric sugars formed by combining 2-7 xylose molecules with β-1,4 glycosidic bonds. Compared with soybean oligosaccharides, fructooligosaccharides, and isomaltose oligosaccharides commonly used by people, it has unique advantages, and it can selectively promote the proliferation activity of intestinal bifidobacteria. Its bifidus factor function is 10-20 times that of other polysaccharides. [0003] Existing xylo-oligosaccharides are generally added with excipients such as maltodextrin, sorbitol, etc., and then dried and powdered. Easy to absorb moisture. In order to solve the problem of moisture absorption, manufacturers generally add anti-caking agents to xylo-oligosaccharides ...
