The principal objective of this study was to determine the quality characteristics of tofu prepared with the addition of skate (Raja kenojei) powder. The moisture, crude ash, carbohydrate, crude protein, and crude lipid contents of the used skate powder were 5.34%, 14.15%, 1.90%, 76.60%, and 2.08%, respectivly. The yield rate of the tofu did not differ significantly with the level of added skate powder; however, significant reductions in pH and a significant increase in acidity were observed. The L and b values of the tofu decreased with increases in the amount of added skate powder in the formulation, whereas the a values increased directly with the amount of added skate powder. Furthermore, hardness was increased significantly as the level of skate powder increased. In terms of overall acceptability, the preferred tofu samples were the control and the group to which, 1.0% skate powder was added.
