Abstract

Freshly squeezed juices were prepared using the domestic Chunggyun, Hanrabong, and imported oranges and physicochemical and sensory characteristics of the juices were investigated. The Chunggyun had significantly the lowest pH value of 3.35, and imported and Hanrabong showed the pH values of 3.82 and 3.93, respectively(p<0.05). The refractive index of Hanrabong showed significantly the highest values of $14.7^{\circ}Bx$ (p<0.05), and the samples of imported and Chunggyun did not show significant differences with indices of 12.5 and 12.2, respectively. The quantitative descriptive analysis(QDA) showed imported sample had significantly the highest values of sweet and sour aroma with values of 11.57 and 11.08, respectively. However, Hanrabong showed significantly the highest value of sweet flavor with value of 12.31. Consumer acceptance test represented the Chunggyun was the most accepted one but did not show any great differences in overall, appearances, and flavor among the samples.
