This study was carried out to investigate the quality characteristics of ginseng Jung Kwa obtained by treatments with different sugars. Ginseng Jung Kwa was made with four different sugars (sucrose, glucose, honey and fructose). Chemical characteristic was measured by ginsenosides content and rheological characteristics were measured by rheometer and color meter. Total ginsenoside and Rf contents on Ginseng Jung Kwa by sucrose were highest at 10.0, and 7.82 ㎎/g, respectively. On ginseng Jung Kwa by fructose, total ginsenoside content was the lowest, and hardness and adhesiveness were the highest, and by honey, stiffness, cohesiveness, gumminess, chewiness, and springiness were the highest, and fracture force did not appear as a significant difference by treatment of different sugars. Coefficient of variance on ginseng Jung Kwa by honey was the highest. On ginseng Jung Kwa by sucrose, color (lightness, redness and yellowness) all were the highest. Browning on Jung Kwa by fructose was the greatest. Sensory evaluation preference analysis (color, taste, texture, flavor and overall acceptability) on ginseng Jung Kwa were determined by 50 panelists (30～50"s age) using 5-point scale. On ginseng Jung Kwa by honey, texture and overall acceptability were the best. Ginseng Jung Kwa by fructose was very sticking and adhering, so preference by sensory evaluation was inferior to others.
