Tea is a famous non-alcoholic beverage worldwide. Various types of tea are prepared to meet the demand of different people. Among the various tea types, green tea (GTE), black tea (BTE), and Pu-erh tea (PEE) are major ones. The objective of this study was to investigate the physicochemical characteristics and antioxidant potential of three tea extracts to be considered as an in-flight beverage. The pH (5.62) of GTE was significantly highest whereas the titratable acidity (0.18 g/100 mL) was significantly highest in BTE. The highest lightness value was found in GTE (87.12) and redness and yellowness in BTE (30.15 and 85.32). The amount of total free amino acid was significantly highest in PEE (174.52 g/ mL), followed by GTE (31.28 g/ mL) and BTE (24.98 g/ mL). Similarly, the antioxidant potential of PEE was significantly high among the three tea extracts. The results indicated that Pu-erh tea could be a good in-flight beverage.
