Abstract: This study evaluated the physicochemical properties of the most common ready-to-drink (RTD) tea beverages in China, and analyzed their polyphenolic profiles and antioxidant capacities. Also,it assessed the daily intake of dietary polyphenols. Results showed that due to the low total soluble solid content, pH and characteristic color parameters, all samples were slightly acidic and showed a slight yellow color. Although different tea beverages contained different concentrations of total sugar, they contained relatively high vitamin C and total phenolics content. Therefore, these beverages showed good antioxidant capacity. HPLC analysis results indicated that these beverages contained five catechins and caffeine, namely, epigallocatechin, gallocatechin, gallocatechin gallate, epicatechin, and epicatechin gallate. In addition, according to the monitoring data from the nutrition and health of Chinese residents during 2010—2012, the average daily polyphenolic intake from RTD teas was estimated to be 33.07 mg/person for Chinese adults.
