Abstract

This study was conducted to evaluate the quality characteristics of Sulgidduk prepared with different amounts of Hasuo (Polygoni Multiflori Radix) powder. Proximate composition analysis showed that the moisture content, pH, acidity, and volume of Sulgidduk decreased with a rise in the level of added hasuo powder. The L-value decreased, while a and b values increased, with increasing amounts of hasuo powder. In mechanical evaluation of physical properties, hardness decreased while springiness, chewiness, cohesiveness, and brittleness increased with increasing hasuo powder content. Scanning election microscopy indicated that the number of air cells decreased as the ratio of hasuo powder increased. Sensory evaluation showed that moistness and springiness decreased significantly when the amounts of hasuo powder increased. The sample containing 30 g hasuo powder scored the highest for sweet taste, savory taste, springiness, chewiness, swallowing, and in overall acceptability scores. Next, the sample containing 60 g hasuo powder scored higher than control. The optimum concentration indicate that addition of 30~60 g hasuo powder to Sulgidduk resulted in highest quality.
