Abstract

This study investigated the quality characteristics of tofu prepared with Boehmeria nivea powder. Moisture, crude ash, carbohydrate, crude protein and crude lipid contents were 7.71%, 20.09%, 39.01%, 31.25% and 0.93%, respectively. The yield of tofu added with BNP increased with addition of BNP, However, there was a significant decrease in pH as well as a significant increase in total acidity. In addition, L, a and b values of tofu decreased with increasing content of BNP. In terms of textural properties, hardness, chewiness and brittleness increased, whereas springiness and cohesiveness decreased, with increasing addition of BNP. In the sensory evaluation, overall preference for tofu added with 0.6% BNP was the highest. According to the results, addition of BNP positively affects the overall sensory evaluation of tofu, and 0.6% is the optimal level.
