In this study, the quality characteristics of salad dressing prepared with mulberry, Schisandra chinensis, and Discorea powder were evaluated. Salad dressing was prepared with salad base (plain yogurt : mayonnaise : fresh cream = 8:1:1), mulberry, Schisandra chinensis for acidity, and Discorea powder for viscosity (4:4:6:1 or 4:4:6:3). Discorea powder was added at levels of 0, 7, and 18% to the salad dressing. As the concentration of Discorea powder increased, the pH level increased, and acidity decreased. Hunter's color L (lightness) value of salad dressing decreased as the amount of Discorea powder increased. Viscosity increased according to the amount of Discorea powder. Moreover, total phenolic content increased according to the amount of Discorea powder. Further, DPPH antioxidant and hydroxyl radical activity of mulberry salad dressing increased as the amount of Discorea powder increased. Sensory preference test results showed that the salad dressing added with Discorea powder had higher scores for color, flavor, taste, and texture than the control. Regarding overall preference, salad dressing containing 7% Discorea powder had the highest scores among the treatments. From these results, salad dressing containing mulberry, Schisandra chinensis for acidity, and Discorea powder for viscosity could be a functional salad dressing with high antioxidant activity.
