Embodiment Construction

[0006] (1) Preparation of agar oligosaccharides:

[0007] The Chinese Patent Application No. 011115094.7 provides a method for preparing agar oligosaccharides by acid hydrolysis. The present invention also provides a method for preparing agar oligosaccharides by enzymatic hydrolysis. The molecular structure of agar oligosaccharides prepared by this method is compared with that of the agar oligosaccharides prepared by the above method. The main chain is 1,3-linked β-D-galactopyranose and 1,4-linked 3,6 internal ether-α-L-galactopyranose residues repeatedly alternating chain neutral sugar linear molecule, average molecular weight In the range of 300-3600kD, the degree of polymerization is in the range of 2-12, but the reducing end is β-D-galactose, and the non-reducing end is 3,6 lactose-α-L-galactose.

[0008] The steps for preparing agar oligosaccharides by enzymatic hydrolysis are:

[0009] First extract agarase (see patent application number 03112515.8 or 03112518.2 for details)...

Abstract

Disclosed is the application of agar oligose as a health preserving component, animal and human body tests have shown that agar ligos is a non digestibility oligosaccharide, and has the functions of promoting growth of bifidobacteria, improving human body immunity, and improving internal secretion system.

Description

Technical field [0001] The invention relates to the application of agar oligosaccharides as prebiotics. 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 intestinal tract, thereby enhancing the host's health. Gibson first proposed the concept of prebiotics in 1995, and now prebiotics as a micro-ecological regulator has been widely studied and applied. Prebiotics can significantly promote the proliferation of intestinal probiotics such as bifidobacteria, and bifidobacteria themselves produce large amounts of lactic acid during their own reproduction. Lactic acid can stimulate intestinal peristalsis, excrete harmful substances in the body, and promote vitamin B1, B2, B6 and the human body Absorption of calcium ions. At the same time, prebiotics inhibit the growth of pathogenic bacteria, spoilage bacteria and other harmful bact...
