Chemical profile, antioxidants, and enzymatic activity of the kombucha tea beverages as a potential anti-obesity beverage
This study aimed to investigate the chemical profile, antioxidant activity, and enzyme inhibition of black tea kombucha and kombucha without tea, as well as the relationship between these three parameters. Both kombuchas of different fermentation time (1, 7, 14, 21 days) had been analysed. The pH an...
