Optimized Paocai Fermentation of Rehmannia Radix: Physicochemical Quality, Untargeted Metabolomics, and Antioxidant Activity
Rehmannia Radix is an important medicinal and edible plant resource in China. However, the production of paocai by fermenting Rehmannia Radix has rarely been reported. This study employed response surface methodology to optimize fermentation conditions, and investigated the changes in physicochemical properties, bioact...
