Effect of Instant Pu'er Tea Content on Kombucha Fermentation

Abstract:

Kombucha Fermentation conditions wereoptimized by pH value and sensory scores.，The fermentation substrates werebrown sugar，and the instant pu-erh tea：water was at 0.8 g∶1 000 mL.when brown sugar content was at 5.5 g and the pH value was at 3.7，the Kombucha beverage was orange，Pleasant aroma，moderate sweet and sour taste，also showed high membrane yield. The microbial results in optimization technique showed that Kombucha was composed of yeast，acetic acid bacteria and lactic acid bacteria. This study discovered new microorganisms which werebeneficial for Kombucha fermentation and human health.
