Effects of Different Drying Methods on the Quality of Forest Ginseng Revealed Based on Metabolomics and Enzyme Activity

Forest ginseng (FG) is a rare medicinal and culinary plant in China, and its drying quality is heavily dependent on the drying method. This study investigated the effects of traditional hot air drying (HAD) and the self-developed negative-pressure circulating airflow-assisted desiccator drying (PCAD) method on the quality of FG using metabolomics and enzyme ac- tivity. The results revealed that the enzyme activities of dried FG were reduced considerably. PCAD preserved higher enzyme activity...
