Kyongdan is a kind of Korean rice cake made from glutinous rice powder. This study attempted to clarify the factors which affect the textural characteristics, and to examine the effects on sensory characteristics and texture of Kyongdan in various soaking time, temperature and volume of adding water in the preparation of Kyongdan. Evaluation was conducted through sensory evaluation and objective evaluation. The degree of gelatinization in various storage time and temperature were evaluated by $\beta$-amylase digestibility. The results were summarized as follows. 1. In preparation, the significant factors were the temperature and volume of water, number of kneading, condition of powder, and the relationships between soaking time and temperature of water and between volume and temperature of water and between volume of water and number of kneading and between volume of water and salt. 2. In sensory evaluation on the various soaking time and temperature and volume of water, the most favorite tendency on the overall quality was at the addition level of hot water of 25% with glutinous rice powder made by soaking for 12 hours. This condition corresponded to the low level of hardness, gumminess, chewiness and the high level of springiness and cohesiveness in comparision with Instron measurement. 3. The degree of gelatinization were decreased rapidly during two days of storage. In storage temperature, Kyongdan which was stored at $0^{\circ}C$, showed the most low level of the degree of gelatinization at the same storage time.
