To enhance gamsulgi quality, the optimal conditions for persimmon peel powder (PPP) addition were evaluated with PPP content(10, 50), sugar content(5, 25) and water content(10, 50%) by reponse surface methodology (RSM). The statistical significanes of sugar element in gamsulgi preperation did not show. Optimal conditions for the content of PPP and water, predicted for each corresponding sensory parameter of gamsulgi, were 10∼40% and 18∼50% for consistency, 10∼32% and 11∼50% for after swallowing, 24∼50% and 14∼39% for color, 10∼40% and 31∼50% for chewiness, 14∼38% and 22∼47% for moistness, 10∼38% and 22∼50% for texture, and 10∼43% and 18∼50% for overall quality. The overall optimal conditions, which satisfied with all sensory properties of gamsulgi, were 25% for PPP content and 35% for water content.
