Abstract

Glycyrrhizae Radix is an herbal medicine vulnerable to fungi. So there are regulations on mycotoxins. Therefore, in this study, the affect of various drying methods and additional gamma irradiation (10 kGy) was studied to suppress the microbial generation of Glycyrrhizae Radix. As a result of detecting and comparing microorganisms using the dry film method for samples prepared by each of natural, hot air, freezing, microwave drying and gamma irradiation, the affect of reducing microorganisms by microwave drying and gamma irradiation was confirmed. There was no statistically significant change in the content of the active compounds between the treatment groups.
