The purpose of this study was to determine the desirable mixture ratio of Rubus coreanus Miquel leaf powder to rice flour for the preparation of sulgidduk. The moisture of samples raged from 41.92% to 38.21%. The addition of Rubus coreanus Miquel leaf powder in the Sulgidduk tended to decrease the lightness (L) in Hunter color value, but to increase the redness (a) and yellowness (b). With increasing Rubus coreanus Miquel leaf powder level, the hardness of the samples decreased and their springiness, cohesiveness and chewiness increased. In sensory evaluation, the addition of 5% Rubus coreanus Miquel leaf powder showed the best score in taste and overall preference. Therefore, these results suggested that the addition of 5% Rubus coreanus Miquel leaf powder could be applied for making Rubus coreanus Miquel leaf powder sulgidduk.
