Abstract

This study was carried out to investigate the acceptable ratio of Sulgidduk with added soybean curd residue powder. The moisture content of Sulgidduk with added soybean curd residue powder (0${\sim}$ 10%) ranged from 40.54 ${\sim}$41.38%, and there were no significant differences between the addition of soybean curd residue powder and control. There were also no significant differences in swelling power and pore ratio from control to the addition of 4% soybean curd residue powder. However, these decreased with increasing addition of soybean curd residue powder of more than 6%. The L (lightness) value decreased with increasing addition of soybean curd residue powder, but the a (redness) and b (yellowness) values increased significantly. As the amount of soybean curd residue powder increased, the hardness, cohesiveness, springiness and gumminess decreased, and, the decrease was especially significant with addition of more than 6%. With increases in the storage period, the hardness, springiness and gumminess increased, while cohesiveness decreased for all additions of soybean curd residue powder. In sensory evaluations, Sulgidduk with the addition of 4% soybean curd residue powder was the most preferred with regard to overall quality. These results indicated that the Sulgidduk with 2% and 4% added soybean curd residue powder exhibited the best quality.
