This study was to investigate the effects of green tea powder addition on the quality of white bread. Initial pasting temperature on amylograph increased and peak and final viscosity decreased with the addition of green tea powder. The lightness values of bread crust decreased and lightness and redness value of bread crumb was not affected, but b values decreased with the increase of green tea powder contents. The volume was significantly reduced with addition of green tea powder up to 5.0% level, compared to that of control. The addition of green tea powder at 2.5% was not affected in most of texture parameters(hardness, springiness, cohesiveness, gumminess and chewiness). But, 10% green tea powder addition to the bread increased significantly hardness, gumminess and chewiness. As results of sensory evaluation, the bread containing 2.5% green tea powder had the highest score in appearance, color, flavor, taste, texture, and overall acceptance. Concludingly, in terms of overall properties, the addition of 2.5% green tea powder to white bread showed the best result.
