- Abstract
Different brands of commercial green tea beverages exhibit different total phenolic contents (TPC) and antioxidant activities (TEACDPPH). In the present study, lyophilized Cosmos caudatus (ulam raja) extract (UREX) was added to different brands of commercial green tea bags at two levels; 25 mg (GT-LUREX) and 50 mg (GT-HUREX) per sachet as an additive for green tea and its effects on their TPC, TEACDPPH, physicochemical and sensory attributes were investigated. The addition of UREX increased yellowness and chroma values of the green tea beverages significantly (P<0.05), however, lightness was significantly (P<0.05) decreased and no influence on the clarity and turbidity was observed. TPC and TEACDPPH were significantly (P<0.05) higher in GT-HUREX when compared to GT-LUREX and control. Sensory attributes of GT-HUREX were significantly (P<0.05) improved. Based on the obtained results, UREX can enhance the nutraceutical and functional properties of green tea beverage, as well as its physical and sensory attributes.
