초록

This study was conducted to investigate the physicochemical and sensory characteristics of tofu prepared with the addition of lotus root powder (LRP). The moisture, crude ash, carbohydrate, crude protein, and crude lipid contents of the lotus root powder were 8.29%, 4.73%, 30.66%, 47.84%, and 8.48%, respectively. The yield rate of the tofu did not differ significantly according to the level of added LRP; however, there was a significant decrease in pH and a significant increase in acidity. The L and b values of the tofu decreased as the amount of LRP in the formulation increased, whereas the a value increased. Furthermore, hardness and cohesiveness increased significantly as the level of LRP increased. In sensory evaluation, LRP tofu had low scores in air cell size and a beany smell, but high scores in hardness. In terms of overall acceptability, the preferred tofu samples were the control and that containing 0.3% lotus root powder.
