Method for keeping cordyceps sinensis fresh by using irradiation method
The technology for fresh Cordyceps sinensis and Cordyceps sinensis is applied in the field of preservation of Cordyceps sinensis, can solve the problems of complicated operation and high equipment dependence, and achieves the effects of reducing the growth rate of polyphenol oxidase activity and the decreasing rate of soluble protein content.
