A comparison experiment on the hot air drying,vacuum drying and vacuum-freeze drying of Coprinus comatus was done.The content of total soluble sugar,soluble protein,Vc,rehydrated ratio and sensory quality of the dired Coprinus comatus were analyzed and evaluated.The results showed that: the content of soluble total sugar,soluble protein and Vc of dried Coprinus comatus by vacuum-freeze drying were 31.39±1.17~Aa,82.96±2.05~Aa and 0.81±0.12~Aa,the Loss significantly lower than the other two drying methods.The rehydrated ratio was 7.15±0.12~Aa,the best of the three.
