We envisage that combined molecular and biochemical analyses like in our study will provide valuable insights for better understanding the role of the microbial community for the beneficial properties of the beverage.Ĭhange in fermentation High throughput sequencing Kombucha tea Microbial community structure and dynamics Radical scavenging T-RFLP.Ĭopyright © 2016 Elsevier B.V. Our data thus indicate that the microbial community structure and dynamics play an important role in the biochemistry of the fermentation of the beverage. Organic kiwi juice is used during fermentation as an energy source for the SCOBY. About one-third of the original caffeine content of tea used may remain after fermentation. We further observed a significantly higher D-saccharic acid-1,4-lactone content and caffeine degradation property compared to previously described Kombucha tea fermentations. Naturally developed during fermentation to replenish the gut and boost immune health. How Much Caffeine Does Hard Kombucha Have. The biochemical properties changed with the progression of the fermentation, i.e., beneficial properties of the beverage such as the radical scavenging ability increased significantly with a maximum increase at day 7. (By comparison, coffee has 100mg of caffeine per 8. The bacterial diversity was higher in the soup than in the biofilm with a peak on the seventh day of fermentation. Our products are considered naturally decaffeinated and contain anywhere from 8mg to 14 mg per serving. Komagateibacter was identified as the single largest bacterial genus present in both the biofilm and the soup (~50%). This is the first report showing Candida as the most dominating yeast genus during Kombucha fermentation. The soup however, showed a significant shift in dominance from Candida sp. The yeast community of the biofilm did not show much variation over time and was dominated by Candida sp.
We hypothesized that several biochemical properties will change during the course of fermentation along with the shifts in the yeast and bacterial communities. In this study, we thus explored the structure and dynamics of the microbial community along with the biochemical properties of Kombucha tea at different time points up to 21 days of fermentation. Moreover, an extensive study into the microbial and biochemical dynamics has also been missing. As for ingredients, the products contain black tea, green tea, kiwi juice used as a sugar source for. It's produced by the kombucha brand GT's and made in various flavors: Strawberry Serenity, Mystic Mango and Cherry Chia, among others.
This, however, may prevent understanding the causal links between the microbial communities and the beneficial properties of Kombucha tea. Synergy Kombucha is a type of kombucha tea you may have seen at your local health foods store. The microbial community and the biochemical properties of the beverage have so far mostly been described in separate studies. The microbial community of Kombucha tea consists of bacteria and yeast which thrive in two mutually non-exclusive compartments: the soup or the beverage and the biofilm floating on it. Kombucha tea, a non-alcoholic beverage, is acquiring significant interest due to its claimed beneficial properties.
