Abstract

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.

Description

technical field [0001] The invention relates to the technical field of an artificial fermentation method for Cordyceps sinensis, in particular to a method for processing fermentation raw materials that can improve the yield and quality of Cordyceps sinensis. Background technique [0002] Cordyceps sinensis, also known as Cordyceps sinensis, is a traditional precious Chinese medicine in my country. It has various pharmacological effects such as relieving cough, reducing phlegm, lowering serum cholesterol, regulating and enhancing immunity, and anti-tumor. In recent years, the demand for Cordyceps sinensis has increased dramatically at home and abroad. But because Cordyceps sinensis has its strict parasitism and special growth geographical environment, the output is quite limited, and the medicine source is relatively scarce. In order to alleviate the contradiction between supply and demand in the market, artificial fermentation products of Cordyceps sinensis are becoming mor...
