The best formula was the one containing 75% (v/v) of red dragon juice in fresh condition with vitamin C content of 19.32±0.62 mg/100 mL, antioxidant activity of 354.25±0.77 ppm, hedonic color, taste, and viscosity between favorable and very favorable. After 2 weeks of storage at room temperature (28±2ºC), the vitamin C, total carotene, and antioxidant activity of the mixture decreased by 29.72, 15.44, and 46.59%, res-pectively.
