The effects of different soaking treatments on the retention and release of active ingredients in Cordyceps sinensis in water are studied,so as to provide a reference for consumers to choose a reasonable soaking method.The results show that the overall active components of Cordyceps sinensis treated with water at 35℃ and 30 min are higher,and the contents of polysaccharide,protein,cordyceps acid and adenosine are the highest,which are 501.5 mg,2 565.2 mg,1 521.2 mg and 5 670.1 μg,respectively.The content of cordycepin under these conditions(561.3 μg)is similar to that of 35℃ and 1 h soaking water treatment(561.9 μg).In addition,repeated soaking in water will significantly reduce the content of active ingredients,so soaking in water multiple times should be avoided.
