Abstract

In this study, sweetened black and green tea were utilized as substrate for kombucha fermentation. Linden, lemon balm, sage, echinacea, mint, and cinnamon infusions were added to kombucha to design a novel beverage with Unproved functional and organoleptic characteristics. After fermentation, the antioxidant capacity (AC) of the kombucha increased by 13.96% 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH), 48.90% ferric reducing antioxidant power (FRAP), and 55.54% cupric reducing AC (CUPRAC). On days 0 and 9 of storage, the bioaccessibility of the total phenolics and AC (FRAP and CUPRAC) in all of the samples showed a significant increase after gastric and intestinal digestion when compared to pregastric digestion (P
