The carbohydrate characteristics and storability of two Korean traditional confections Seban-kangjeong (a Korean fried waxy-rice cookie) and starch-dashik (a Korean pressed starch cookie) were studied as compared with two Western confections fried cookie and biscuit. Seban-kangjeong showed lower contents of starch and sucrose and higher content of reducing sugar whereas starch-dashik showed higher contents of starch and sucrose and lower content of reducing sugar. Moisture content was higher in Korean confections than in Western confections. The degree of gelatinization was higher in Seban-kangjeong and fried cookie which were made through a frying process. Moisture adsorption isotherms were constructed for the four products. In storage test for 6 months under different temperature and humidity conditions, the relative humidity maintaining the initial moisture content of products was 68% for Seban-kangjeong and starch-dashik and 20% for fried cookie and biscuit. The ratio of retrogradation in storage was 15% in Seban-kangjeong, 20% in starchdashik and 28% in fried cookie and biscuit, showing the lowest progress in freezer storage.

The purpose of this study was to determine the most appropriate ratio for burdock glutinous rice Dasik. Burdock glutinous rice Dasik was prepared with different levels of burdock powder (0, 3, 6, 9 and 12%) and the quality characteristics of burdock glutinous rice Dasik were analyzed. Moisture contents of burdock glutinous rice Dasik increased as the amount of burdock powder increased (p<0.001) compared to the control group. The L-value, a-value, and b-value of burdock glutinous rice Dasik showed a tendency to decrease compared to the control group. The sugar content of burdock glutinous rice Dasik increased (p<0.001) with the amount of burdock powder. The hardness and adhesiveness of the glutinous rice Dasik with burdock powder of 6% or less were decreased, but those with 9% or more burdock powder had higher hardness and adhesiveness than the control group. In addition, the cohesiveness, springiness, gumminess, and chewiness of glutinous rice Dasik with burdock powder increased compared to the control group. The DPPH free radical scavenging activity of the glutinous rice Dasik with 9% and 12% burdock powder were higher than that of the control group (p<0.001). In the sensory test of burdock glutinous rice Dasik, the samples added with 3% and 6% burdock powder gained higher preferences, but the evaluations of others were lower than that of the control group. The glutinous rice Dasik with less than 6% burdock powder was highly evaluated, so it is considered as the most appropriate sample.
