Abstract

|
This study examined the quality characteristics of Sulgitteok samples prepared with different ratios of lotus root powder over 4 days of storage. The moisture contents of the lotus root powder-containing samples ranged from 35.39 to 37.31% and that of the Sulgitteok without lotus root powder control was 35.92%. The results showed that the various samples had the inconsistent changes during the storage period. As the content of lotus root powder increased, the ；L-values of samples decreased and the a- and b-values increased. However, their L-, a- and b-values did not show large differences with storage. When compared to the control, the hardness, gumminess, and chewiness of samples slowly increased as the amount of lotus root powder increased. Springiness and cohesiveness decreased according to the amount of added lotus root powder. And increasing amounts of lotus root powder and storage time resulted in greater reductions in adhesiveness. In addition, increasing storage time caused cohesiveness to decrease and springiness to increase. The sensory evaluation results showed that the 20% lotus root Sulgitteok received the highest scores, therefore, this samples was deemed superior.
