Abstract

This study was conducted to investigate the quality characteristics of tofu prepared with the addition of shrimp powder. Moisture, crude ash, carbohydrate, crude protein, crude lipid of the used shrimp powder were 3.81%, 0.70%, 42.15%, 49.36%, and 3.98%, respectivly. The yield rate of the tofu did not differ significantly according to the level of added of shrimp powder, however there was a significant decrease in pH and a significant increase in acidity. The L and b values of the tofu were decreased as the amount of shrimp powder in the formulation increased, whereas the a values was increased. Furthermore, hardness was significantly increased as the level of shrimp powder increased. In terms of overall acceptability, the preferred tofu samples were the control and that containing 2.0% shrimp powder addition group.
