To explore the potential storage and safety of drinking leftover bottled tea beverages from various manufacturers after direct drinking from bottles, we conducted a screening experiment on the growth of salivary bacteria in plastic bottles of tea. The diluted saliva samples from 10 participants were inoculated into the test bottled beverages, which resulted in bacteria, particularly former members of the genus Lactobacillus, growing in some green tea beverages with a neutral pH. In contrast, tea beverages with less bacterial growth contained Streptococcus spp., and the leftovers may be safe to store and drink again.
为了探索直接从瓶中饮用不同制造商生产的瓶装茶饮料后的潜在储存和安全性，我们对茶饮料瓶中唾液细菌的生长情况进行了筛选实验。将 10 名参与者的稀释唾液样本接种到测试瓶装饮料中，结果发现一些 pH 值呈中性的绿茶饮料中出现了细菌生长，特别是以前的乳杆菌属成员。相比之下，细菌生长较少的茶饮料中含有链球菌属，这些剩余的茶饮料可能可以安全储存并再次饮用。
