Backsulgi were prepared with the addition of nutriprotein powder at 0%, 2%, 4%, 6%, 8%, and their sensory quality and mechanical characteristics were compared. In addition, the changes in the sensory and textural characteristics of Backsulgi were determined while storing them at the temperatures of 4$^{circ}C$ and 20$^{circ}C$ for 0, 1, 2, and 3 days. In the sensory evaluation, Backsulgi with 4% nutriprotein powder showed the highest score in overall quality. In the measurement of color changes, L value (lightness) was decreased, but a value (redness) and b value (yellowness) increased as the addition of nutriprotein powder increased. In textural characteristics, the hardness, gumminess and cohesiveness of Backsulgi were decreased by the increase of nutriprotein powder. The hardness and gumminess were increased as the storage time increased.
