Abstract: To obtain a kombucha-fermented beverage with stable quality and good taste, this study
used total sugar, total acid, and sensory score as indexes to explore the mixing ratio of
fermentation strains, and optimized the fermentation conditions by single factor and response
surface experiment. The results showed that the optimal ratio of Komagataeibacter xylinus 1512,
Zygosaccharomyces bailii 1484, and Lactobacillus. plantarum 1298 was 2:1:1. The optimal
technological conditions of the new kombucha were % of tea dosage, 8% of sucrose dosage,
6% of inoculation dosage, and fermented at 30 ℃ for 7 d. Under the optimized conditions, the
sensory score, total acid, total sugar, and total phenol of kombucha were points, mg/mL,
mg/mL, and mg/mL, respectively. The new kombucha had shorter fermentation time
and superior taste than the traditional kombucha.
