Embodiment Construction

[0006] (1) Preparation of alginate oligosaccharides:

[0007] Chinese patent application number 02135571.1 provides a method for preparing alginate oligosaccharides by chemical oxidation. Chinese patent application number 01107952.5 provides a method for preparing alginate oligosaccharides by acid hydrolysis.

[0008] The invention provides a method for preparing algin oligosaccharides by enzymatic hydrolysis, the molecular structure of the algin oligosaccharides prepared by this method is compared with the structure of the algin oligosaccharides prepared by the above two methods, the main chain Both are linear molecules formed by the continuous or alternate connection of α-L-guluronic acid and β-D-mannuronic acid. The average molecular weight is in the range of 500-2000, and the degree of polymerization is 2-10. The difference is that there is an unsaturated double bond between the carbon 4 and carbon 5 positions of the reducing end.

[0009] The steps of preparing alginate...

Abstract

An application of the algin oligose in preparing medicine, food additive, helth-care food, or feed additive for preventing and treating tumor and intestinal infection, elongating life, and beautifying skin is disclosed.

Description

Technical field: [0001] The present invention relates to the application of algin oligosaccharide as a prebiotic. Background technique: [0002] Prebiotics are substances that are not digested by the host's gastrointestinal tract and can selectively stimulate the growth of one or several beneficial bacteria in the host's intestines, thereby improving the health of the host. Gibson first proposed the concept of prebiotics in 1995, and now prebiotics have been widely studied and applied as a kind of microecological regulator. Prebiotics can significantly promote the proliferation of intestinal probiotics such as Bifidobacteria, and Bifidobacteria itself produces a large amount of lactic acid in the process of self-reproduction. Lactic acid can stimulate intestinal peristalsis, excrete harmful substances in the body, and promote vitamin B1, B2, B6 and human body. absorption of calcium ions. At the same time, prebiotics inhibit the growth of harmful bacteria such as pathogenic...
