Compares bacterial counts in green tea beverages before and after storage, suggesting implications for beverage safety.
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) × 10 3 and (4.5 ± 3.9) × 10 3 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) × 10 4 and (1.6 ± 3.1) × 10 3 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.
