ABSTRACT: The drying and microwave drying conditions of Cordyceps militaris and their effects on the main active ingredients were studied. The results showed that the drying rate increased with the increase of drying temperature, and there were significant differences at all test temperatures. More than 75% of the moisture was lost in the first two hours. With the increase of microwave drying power, the drying rate also increased, and reached a very significant difference under each test microwave drying power. More than 75% of the moisture was lost in the first two hours. Lost in the first 6 minutes.
For the content of active ingredients, 900W is the best in microwave drying equipment, which is significantly higher than other power. Cordycepin content is the highest at 60 C, while adenosine content is the highest at 70. In production, different drying conditions can be selected according to needs.
Key words: microwave drying of silkworm caterpillar fungus; drying; drying rate; active ingredients
Silkworm caterpillar fungus, which has similar active ingredients with Cordyceps sinensis, is a very valuable potential alternative to Cordyceps sinensis, and because of its ability to cultivate artificially, has formed a huge industry in China. The content of cordycepin and adenosine is an important index to evaluate the quality of Cordyceps militaris products. In addition, drying is an important link in the production of Cordyceps militaris, which directly affects the quality of products. It is of great significance to study the drying conditions of silkworm caterpillar fungus and their effects on the content of active ingredients for the further development of silkworm caterpillar fungus.
