| titleOfInvention | Preparation method of chitosan oligosaccharide |
| abstract | The invention provides a preparation method of chitosan oligosaccharide, relating to the preparation of chitosan oligosaccharide, which specifically comprises the following steps: (1) gelatinizing chitosan: dissolving chitosan in acid solution to obtain colloidal chitosan, and heating; (2) enzymolysis: adding the complex enzyme A into the colloidal chitosan, heating and stirring, adding the complex enzyme B, stirring at constant temperature, adding the chitosan enzyme, and continuously stirring to obtain a chitosan enzymolysis liquid; (3) separation: and centrifuging the chitosanase hydrolysate, and performing membrane concentration to obtain the chitosan oligosaccharide. The preparation method can obtain the chitosan oligosaccharide with narrow molecular weight distribution and high content, and further can be more effectively applied to the fields of fertilizers, feeds, pesticides and the like. |
