In this study, the quality characteristics of jelly with black garlic (0, 10, 20, and 30%) were evaluated. The pH of jelly with black garlic decreased according to the amount of black garlic added. The sugar content of the jelly increased significantly with added black garlic. Lightness, redness, and yellowness decreased with increasing black garlic content. Moreover, the textural properties, which included hardness, springiness, cohesiveness, gumminess, and chewiness decreased in jelly that contained black garlic compared to the controls. Additionally, the antioxidant activity of jelly that contained black garlic increased in a concentration dependent manner. The IC50 values of the DPPH radical scavenging activity for jelly that contained 10, 20 and 30% black garlic were 132.47, 50.97, 40.06, and 30.41 mg/mL, respectively. The IC50 values of the hydroxyl radical scavenging activity of jelly decreased as the black garlic concentration increased. Finally, sensory results showed that the scores of over-all preference and buying intention for jelly with 20% black garlic were the highest.
