Embodiment 1

[0031] The extraction method of chicory root polysaccharide includes the following steps:

[0032]S1, take fresh chicory root, wash and dry with water, crush into powder, and pass the powder through a 20 mesh sieve;

[0033] S2, the powder obtained in step S1 and deionized water are mixed according to the ratio of 1:20 feed and liquid, and the hot water is soaked at a temperature of 80 °C to obtain a crude polysaccharide solution;

[0034] S3, the crude polysaccharide solution obtained in step S2 is rapidly cooled at low temperature, filtered with 100 nylon cloth to remove the residue;

[0035] S4, the solution obtained in step S3 was added to 80% ethanol alcohol sink;

[0036] S5, the solution obtained in step S4 is concentrated in vacuo to one-third of the original volume to obtain the concentrate;

[0037] S6, the concentrate obtained in step S5 was added to the Sage solution to remove the protein, and after the protein was removed, the gel column was chromatographed to obtain...

Embodiment 2

[0056] The difference between the present embodiment and Example I is that in step A1 of the preparation method of chicory root polysaccharide hypoglycemic beverage, according to the mass percentage weighing crude polysaccharide solution 0.2%, vitamin C 0.01%, citric acid 0.01%, xylitol 1.2%, flavor 0.001%, the remaining amount is water.

Embodiment 3

[0058] The difference between the present embodiment and Example I is that in step A1 of the preparation method of chicory root polysaccharide hypoglycemic beverage, the crude polysaccharide solution was weighed according to the mass percentage 0.3%, vitamin C 0.015%, citric acid 0.015%, xylitol 1.8%, flavor 0.001%, the remaining amount is water.

Abstract

The invention relates to a chicory root polysaccharide, an extraction method thereof and a preparation method of a hypoglycemic beverage containing the chicory root polysaccharide, and belongs to the technical field of biotechnology, beverage and food.The preparation method of the chicory root pure polysaccharide comprises the steps that chicory roots are smashed, mixed into a solution according to a certain material-liquid ratio and extracted with hot water to obtain chicory root crude polysaccharide, residues are removed, and the chicory root polysaccharide is obtained. Performing alcohol precipitation, concentration, protein removal and the like to obtain pure polysaccharide of the chicory roots; the preparation method of the sugar-reducing beverage containing the chicory root polysaccharide includes the steps of formula weighing, primary mixed sterilization, secondary mixed sterilization, filling and the like. According to the invention, non-inulin micromolecular polysaccharides are extracted from chicory roots, and the functions of the non-inulin micromolecular polysaccharides are researched to prove that the new polysaccharides have hypoglycemic activity, so that the chicory roots have the hypoglycemic activity; and by utilizing the characteristic of reducing blood sugar of the chicory root polysaccharide, the blood sugar reducing beverage taking the chicory root polysaccharide as the main component is researched and developed, the blood sugar reducing value of the chicory root polysaccharide is fully utilized, and the health of a human body is benefited.

Description

Technical field [0001] The present invention relates to a polysaccharide and extraction method and application thereof, in particular to a chicory root polysaccharide and extraction method thereof, containing chicory root polysaccharide hypoglycemic beverage preparation method, which belongs to the field of biotechnology, beverage and food technology. Background [0002] Chicory (Cichorium intybus L.), a genus of chicory in the family Asteraceae, is a perennial herb. The roots are fleshy and short and thick. The stem is erect, ribbed, hollow, and multi-branched. The leaves are alternate, long inverted lanceolate, head-shaped inflorescence, corolla tongue-shaped, and blue-blue in color. Chicory is a medicinal and food dual-use plant, the leaves can be concocted into lettuce, the root contains inulin and aromatic substances, can be used to make substitute coffee, promote the activity of human digestive organs. The aerial parts and roots of the plant can be used for medicinal purpo...
