Abstract

The invention relates to a method for synchronously extracting cordyceps militaris polysaccharide from composite dual enzymes. The method comprises the following steps of crushing dried cordyceps militaris, adding water, mixing the crushed cordyceps militaris with the water, adjusting pH, performing enzymolysis and the like so as to obtain a cordyceps militaris stock solution. The cordyceps militaris polysaccharide is extracted by an enzyme method, so that the extraction rate of the cordyceps militaris polysaccharide can be effectively increased, besides, the structure and the composition of the cordyceps militaris are not destroyed, the exertion of the efficacies of the cordyceps militaris is facilitated, and the utilization rate and the absorptivity are increased.

Description

technical field [0001] The invention relates to a method for extracting fungal polysaccharides, in particular to a method for synchronously extracting polysaccharides from Cordyceps militaris with compound double enzymes and its application in processing Cordyceps militaris beverages, belonging to the field of high-tech processing. Background technique [0002] Wang Pu et al focused on the pharmacological activity of Cordyceps polysaccharides through the chemical structure of Cordyceps polysaccharides, especially anti-tumor, hypoglycemic, protective effects on liver and kidney function, and immune regulation, and proposed that Cordyceps polysaccharides can be applied to food and play a role in human health. to a significant effect. He Jianli et al. researched and summarized the detection methods of functional components in Cordyceps, such as cordycepic acid, cordycepin, polysaccharides, sterols, and superoxide dismutase, which can be applied to the quality control and develo...
