Effects of Prunus mume byproduct (PLB), obtained after manufacture of Prunus mume liquer, on quality characteristics of bread were investigated. The pH of dough and bread decreased but titratable acidity increased by addition of 10% or 20% PLB. The volume of dough during fermentation and the baking loss of bread containing PLB were smaller than those of the dough and bread without PLB. The weight of bread increased but the volume decreased by addition of PLB. L (lightness) value increased and a (redness) value decreased in the surface of bread containing PLB. b (yellowness) value did not show difference between treatments. The internal color of bread containing PLB decreased in L and a value but increased in b value. The hardness and strength of bread decreased with 10% PLB but increased with 20% PLB compared to control. Cohesiveness and springiness of bread increased with 10% or 20% PLB, but did not show significant difference between concentrations. As results of sensory evaluation, taste and flavor of the bread containing 10% PLB increased significantly compared to control. The sensory quality of bread with 20% PLB decreased significantly. The strength, springiness, and hardness of bread with 20% PLB were higher than those of control. The taste, flavor, color, and overall acceptability of bread with 10% PLB were better than those of control. No molds were found in breads with 20% PLB and 20% PLB powder during storage for 1 week at room temperature.
