Abstract

The invention discloses oligodextrose and a preparation method thereof, and belongs to the field of oligosaccharides. The preparation method comprises the following steps of: mixing polysaccharide, an adsorbent and a salt solution, and reacting to obtain the oligodextrose, wherein the adsorbent is one of a resin material and an activated carbon material or above, the polysaccharide is one of cellulose and chitosan or above, and the salt solution is one of a LiBr solution, a LiCl solution, a ZnCl2 solution and a ZnBr2 solution or above. According to the preparation method, selective conversion of cellulose to oligosaccharide with a specific polymerization degree (2-20) is realized, and the selectivity of the obtained oligosaccharide reaches 90% or above. Meanwhile, the oligosaccharide concentration can be increased to 200 g / L or above, and the highest oligosaccharide concentration reaches 247.1 g / L. In addition, the resin material adopted by the invention can be oxidized and regenerated through hydrogen peroxide to keep stable properties.

Description

technical field

[0001] The invention belongs to the field of oligosaccharides, and in particular relates to an oligosaccharide and a preparation method thereof. Background technique

[0002] Glucose oligosaccharides with a degree of polymerization of 2-20 are an important raw material for prebiotics. This type of oligosaccharide cannot be transformed and utilized by the upper digestive tract of the human body, but can be transformed and absorbed by probiotics such as bifidobacteria in the intestinal tract, thereby regulating the intestinal tract environment for the growth of colonies, inhibit the growth of harmful bacteria, improve the body's ability to absorb minerals, and protect human health. In recent years, the market expansion of prebiotic oligosaccharides at home and abroad has been extremely rapid, and oligosaccharides have also attracted more and more attention as a high value-added chemical.

[0003] The traditional oligosaccharide preparation technology is mainly...
