Data are mean ± SD (expressed as milligram of quercetin equivalent per liters of kombucha solution, mg QE/L);

Values with the different capital letters within a column are significantly different at p < 0.05, while the values with the different lowercase letters within a row are significantly different at p < 0.05 based on LSD analysis.
