Study on the differences of main components, enzyme activities and microbial composition between defective and normal JIUYAO.

The quality of JIUYAO was significantly affected by the water content. Due to the different abundances of aerobic and anaerobic bacteria in JIUYAO, oxygen may also be an important parameter affecting the quality of JIUYAO. We believe that the present study offers a theoretical basis for the quality evaluation and control of JIUYAO. This article is protected by copyright. All rights reserved.
