Abstract
This study was conducted to investigate the quality characteristics of tofu (soybean curd) prepared with the addition of Enteromorpha intenstinalis powder (EIP). The moisture, crude ash, carbohydrate, crude protein, and crude lipid contents of the EIP were 6.04%, 24.09%, 39.68%, 28.25%, and 1.94%, respectively. The yield rate of the tofu did not differ significantly according to the level of added EIP, however there was a significant decrease in pH and a significant increase in acidity. The L and a values of the tofu color were decreased as the amount of EIP in the formulation increased, whereas the b values was increased. Furthermore, hardness and brittleness were significantly increased as the level of EIP increased. In terms of overall acceptability, the preferred tofu samples were the control and that of tofu mixed with 0.2% EIP addition group.
