Method for extracting agaric polysaccharides

Abstract

The invention relates to the technical field of bio-extraction and in particular relates to a method for extracting agaric polysaccharides. The method comprises the following steps: performing freezedrying, superfine grinding, zymolytic wall breaking, pre-extract preparation, microwave extraction and concentrated drying, breaking structures between agaric cells and cell walls thereof, grinding tissue structures of the agaric, enlarging an enzymolysis contact surface, performing microwave extraction through rose cell sap and agaric freeze-dried powder, and rapidly separating out polysaccharideactive substances in agaric by virtue of beta-phenylethanol in the rose cell sap and volatile matters thereof. The used liquid-to-solid ratio is reduced, and the efficiency of extracting the agaric polysaccharides is increased.

Description

Technical field

[0001] The invention relates to the field of biotechnology, in particular to a method for extracting polysaccharides from fungus. Background technique

[0002] Fungus, belonging to the Basidiomycetes, Fungus, Fungus family. Dark brown color, soft taste, smooth taste, rich in nutrition, can be cooked or served cold, it is not only an ingredient for cooking delicious dishes, but also has medicinal uses such as nourishing blood and nourishing skin, making skin ruddy, preventing iron deficiency anemia, etc. effect. Among them, fungus polysaccharide is the main biologically active component in fungus, which has functions such as immune regulation, anti-tumor, anti-oxidation, lowering cholesterol, and regulating blood sugar.

[0003] At present, most of the extraction techniques of fungus polysaccharides are enzymatic hydrolysis, supersound-assisted extraction, microwave-assisted extraction, superfine pulverization and other methods. There are also extraction methods th...
