Abstract
This study compared bacterial counts and composition in plastic-bottled green tea beverages immediately after direct drinking and after storage at 37°C for 1 day. Immediately after drinking, (1.9 ± 1.6) × 103 and (4.5 ± 3.9) × 103 colony forming units (CFU)/mL were recovered from standard green tea and strong green tea, respectively. After 1 day of storage, (1.3 ± 1.5) × 104 and (1.6 ± 3.1) × 103 CFU/mL were recovered from standard green tea and strong green tea, respectively. Following storage, Lacticaseibacillus spp., Streptococcus, and Veillonella were isolated from both beverages.
