The feasibility of incorporating jujube concentrate (JC) as a value-added food ingredient in convenience food prod-ucts was investigated using a model system of gelatin jelly. With an increasing level of JC added, the pH, moisturecontent, and lightness gradually decreased while the soluble solids content increased (p<0.05). Hardness and totalpolyphenol content also increased significantly with a higher amount of JC in the formulation (p<0.05). A con-sumer acceptance test indicated that the addition of JC had a favorable effect on consumer preferences in allattributes. Jelly with 20% JC is recommended (with respect to the overall preference score) for taking advantage ofthe functional properties of JC without sacrificing consumer acceptability.
