Abstract
Dilution concentration of watermelon juice, concentrations of added sugar, citric acid, and vitamin C, sterilization temperature and time, and natural color extracts were evaluated to determine optimum conditions for watermelon beverage production. Optimum dilution concentration of watermelon juice and optimum content of soluble solid were 40% and $12^{\circ}Brix$, respectively. Addition of 0.5 and 0.3 g/L or 1.0 and 0.3 g/L citric acid and vitamin C gave optimum sensory quality. Sterilization of watermelon beverage at above $70^{\circ}C$ decreased redness. Sterilization at $60^{\circ}C$ for 10 to 30 min or at $70^{\circ}C$ for 10 min achieved best sensory quality. Addition of 20 g/L raspberries gave best sensory quality among raspberries, omija, and borage. Hot water was better than alcohol for extraction of natural color. Ratio of extracts for optimum sensory quality was 7 : 3 for extract of 20 g raspberries/L : extract of 30 g omija/L.
