The feasibility of incorporating jujube powder as a value-added food ingredient in bakery food products, using a model system of muffins, was investigated. Jujube powder was incorporated into muffins at 0, 5, 10, 15, and 20% weight amounts based on the total weight of wheat flour. Qualities, such as pH, volume index, height, and moisture content, of muffins decreased significantly with increasing levels of jujube powder added (p<0.05). In terms of color, lightness decreased, whereas redness increased significantly for both crust and crumb (p<0.05) with increasing levels of jujube powder. Baking loss also decreased gradually, while hardness and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity were significantly influenced with higher amounts of jujube powder in the formulation (p<0.05). Finally, the consumer acceptance test indicated that the highest levels of jujube incorporation (20%, w/w) had a considerable adverse effect on consumer preferences in all attributes. In contrast, muffins with moderate levels of jujube powder (10%, w/w) are recommended (with respect to overall preference score) for taking advantage of the functional properties of jujube powder without sacrificing consumer acceptability.
