The manufacturer of D-mannose powder tells you that oligomannose is made up of D-mannose connected by β-1, 4 glycosidic bonds to form the main chain, and glucose is connected to the main chain or branched chain. The degree of polymerization is between 2-10. Oligosaccharides. The manufacturer of D-mannose powder tells you that it is a new type of prebiotic, which can activate and multiply bifidobacteria and lactic acid bacteria in large quantities, and adjust the micro-ecological balance.

The manufacturer of D-mannose powder tells you that the methods of separation and purification of oligosaccharides mainly include activated carbon column chromatography, yeast fermentation and gel column chromatography. The yeast fermentation method needs to screen out suitable yeast strains first and requires relatively simple sample components. The separation effect of gel column chromatography is very good and the speed is fast, but the cost of the gel used is very high, and the sample load is greatly restricted. The manufacturer of D-mannose powder tells you that in comparison, activated carbon column chromatography has low cost, good separation effect, large sample load, and also has the effect of decolorization and desalination, which is very suitable for preparing single oligosaccharide products.
The manufacturer of D-mannose powder tells you that the production methods of oligomannose mainly include extraction from natural raw materials, chemical degradation and biodegradation. The post-processing of the first two methods is more complicated, and the chemical method with acid-base hydrolysis is costly and pollutes the environment. The manufacturer of D-mannose powder tells you that the biodegradation process is non-toxic and safe, with mild reaction conditions, low energy consumption, saving resources and protecting the environment. It is the most ideal method for producing MOS. The enzymatic production of mannose oligosaccharides is mainly restricted by the low catalytic efficiency of the key enzymes used, the high production and use costs of the enzymes, and the high substrate viscosity that makes it difficult to achieve high-concentration production. Therefore, in order to realize the industrial production of mannose oligosaccharides prepared by enzymatic method, the manufacturer of D-mannose powder tells you that a breakthrough must be made in the research of the key enzymes that hydrolyze KGM.
