Effects of drying methods and refrigeration conditions on the content of main active ingredients in Cordyceps militaris

ABSTRACT: Cordyceps militaris was inoculated with silkworm larvae as host and cultivated artificially to obtain Cordyceps militaris. Cordycepin and adenosine in Cordyceps militaris were determined by different drying methods and refrigeration conditions.
Fresh Cordyceps militaris was treated with microwave drying equipment. The content of cordycepin was higher when microwave power was 900 W and 720 W (P<0.01), and the content of adenosine was the highest when microwave power was 900 W (P<0.01). Fresh Cordyceps militaris was dried at high temperature, and the content of cordycepin was the highest when drying temperature was 60 C (P<0.01), and the content of cordycepin was the highest when drying temperature was 100 C. The content of adenosine was the lowest (P < 0.01) and the highest (P < 0.01) when the drying temperature was 70 C. Compared with microwave drying, high temperature drying, freeze drying and indoor shade drying, the content of cordycepin and adenosine in Cordyceps militaris treated by microwave drying was the highest (P < 0.01).
