Abstract

The invention provides a crosslinked synanthrin preparation method. Water solution containing synanthrin and crosslinking agents is prepared, the pH (potential of hydrogen) of a system ranges from 7 to 11, and reaction is performed at the temperature of 15-75 DEG C to obtain crosslinked synanthrin. Phosphate groups of synanthrin molecules are crosslinked to prepare synanthrin phosphate, the average degree of polymerization of the synanthrin phosphate is obviously improved, and the synanthrin phosphate has higher viscosity and gel properties.

Description

technical field [0001] The invention relates to the technical field of inulin production, in particular to a preparation method of cross-linked inulin. Background technique [0002] Inulin, also known as inulin and inulin, is mostly found in Compositae plants, such as the tubers of Jerusalem artichoke and dahlia and the roots of chicory and burdock. Inulin is a natural fructose polymer, which is composed of D-fructofuranose molecules connected by β-(2,1) glycosidic bonds, and the end of each inulin molecule is connected with a glucose residue by α-(1,2) glycosidic bonds. The degree of polymerization is usually 2-60, and the average degree of polymerization is 10. As a biological polysaccharide, inulin has various physiological functions such as intestinal probiotics, promoting mineral absorption, anti-oxidation, lowering blood sugar, and lowering blood lipids. At the same time, inulin has good solubility, gel properties, moisture retention and high viscosity, which can imp...
