The purpose of this study was to determine the most desirable mixture ratio of tomato powder to rice flour for the preparation of tomato Sulgidduk(Sulgidduk containing tomato powder). The moisture contents of samples ranged from 38% to 42%. The L-value decreased, while a- and b-values increased, with increasing amounts of added tomato powder. Also, the pH of samples decreased with increasing amounts of tomato powder. In the mechanical evaluation of physical properties, hardness, adhesiveness, cohesiveness and springiness decreased with increasing tomato powder content. And throughout the storage period, gumminess and chewiness decreased. Based on sensory evaluations, the tomato power intensified the color, flavor, sweetness and sourness of the Sulgidduk. The sample containing 6% tomato powder had the highest softness, moistness, chewiness and the overall-acceptability scores. Consequently, the addition of 6% tomato powder to the rice flour was determined to be the best formula for tomato Sulgidduk in terms of the sensory qualities such as softness, moistness, chewiness and overall-acceptability.
