Description

technical field

[0001] The invention belongs to a method for regulating the degree of polymerization of oligosaccharides, in particular to a method for regulating the degree of polymerization of oligosaccharides prepared by enzymatic method. Background technique

[0002] Oligosaccharides generally refer to functional molecules composed of 2-10 monosaccharides and have certain physiological activities. The main functions are: can promote the proliferation of bifidobacteria, inhibit the harmful growth of intestinal tract, such as oligosaccharides, etc.; have the ability to inhibit tumor growth, enhance the body's immunity, and reduce blood cholesterol, such as oligomeric grapes; It can hinder the growth and reproduction of pathogenic bacteria and enhance the defense ability of plants against pests and diseases, such as galactooligosaccharides. Therefore, it is widely used in medicine, health food and agriculture. Oligosaccharides are usually obtained by degrading polysacchar...
