Preparation method and application of NMN nano-microspheres

The invention relates to the technical field of beta-nicotinamide mononucleotide preparation, in particular to a preparation method and application of NMN nano-microspheres. The preparation method comprises the following steps that (1), NMN particles are dispersed in a coating material and stirred to be uniform, mixed powder is obtained, and the coating material is prepared from the components in parts by weight: 8-15 parts of zein ethyl alcohol, 10-15 parts of lac ethyl alcohol, 12-18 parts of gelatin, 25-35 parts of konjac glucomannan and 20-30 parts of nanometer bone meal; and (2), a wetting agent and an adhesive are added into the mixed powder for being uniformly stirred, and drying is carried out to obtain the NMN nano-microspheres with the core-shell structure. According to the preparation method and application of the NMN nano-microspheres, the NMN nano-microspheres are coated in the coating layer with special components, so that the problem that the NMN is prone to being influenced by the environment
