Abstract
The invention discloses a biosynthesis method of dendritic glucosyl nanoparticles, and belongs to the technical field of carbohydrate deep processing. According to the biosynthesis method of the dendritic glucosyl nanoparticles, cyclodextrin is taken as the raw material, and the dendritic glucosyl nanoparticles are prepared by a one-pot synthesis technology based on the cooperative catalysis of invitro polysaccharide enzyme preparation. The biosynthesis method is simple in process, controllable in reaction conditions and continuous in production, and further has the characteristics of low cost, environmental friendliness and the like. The diameter size of the dendrimer glucosyl nanoparticles is 20-100nm, the absolute molecular weight is greater than 1.0 *10<5>g/mol, the polydispersity coefficient is less than 1.3, and the branch density is 6-12%. The dendrimer glucosyl nanoparticles can be widely used as carriers in industries of nutrition food, medicine, cosmetics and the like.
