Fermentation raw material treatment method for improving yield and quality of cordyceps sinensis

The invention provides a fermentation raw material treatment method for improving the yield and quality of cordyceps sinensis. Protease is added, so that the yield and quality of a product are improved. The fermentation raw material treatment method comprises the following steps of: adding 0.2-0.4 percent (enzyme mass/culture medium mass) of protease into a prepared liquid seed culture medium; performing enzymolysis and inoculation. The enzymolysis conditions are that the enzymolysis temperature is 45-55 DEG C, and enzymolysis time is 4-8 hours.
