Abstract

The present invention relates to preparation and application of crust oligosaccharide and belongs to the field of deep chitin processing technology. Non-specific enzyme is used to raise the hydrolysis degree of chitosan and the separation and purification of hydrolytic product. The key point of the present invention is that the chitosan material is produced into crust oligosaccharide powder through acid dissolving, heating, enzymolysis and hydrolysis with compoiste, enzyme comprising polysaccharide hydrolase, proteinase and lipase, deactivating enzyme, filtering, ultrafiltering, ion exchange or nanometer filtering, vacuum concentration and drying. The product is used in producing various functional health foods with the functions of immunological regulation and blood fat regulation.

Description

technical field

[0001] The invention relates to a preparation method and application of chitooligosaccharides, in particular to a preparation method of chitooligosaccharides using a compound enzyme hydrolysis method and the application of chitooligosaccharides, belonging to the technical field of chitin deep processing. Background technique

[0002] Chitooligosaccharides are a class of water-soluble oligosaccharides linked by N-acetyl-D-glucosamine (NAG) and / or D-glucosamine (GA) through β-1,4 glycosidic bonds. Prepared by hydrolyzing chitin or chitosan. Chitin and chitosan can be obtained from the shells of shrimps and crabs, the shells of insects and the cell walls of fungi through acid-base treatment. This is a renewable resource, the total amount of resources on the earth is second only to cellulose. However, compared with cellulose, its structure contains acetamido or free amino groups in addition to hydroxyl groups. Its functional properties and uses are more importa...
