This study was carried out to investigate the quality characteristics of Baiksulgis made of imported rice(Thai and Chinese rice, harvested in 1998) and domestic rice(Chuchung byeo, harvested in 1998 and 1997). Moisture content, color value, yields of reducing sugar by $\beta$-amylase reaction, texture and sensory properties of Baiksulgis were measured. Moisture contents of rice flour and Baiksulgi made of Korean rice harvested in 1997 were highest and those of Thai rice were lowest among the samples. This tends were also seen during storage. Lightness and redness of Baiksulgi made of Thai rice were lowest and yellowness of Baiksulgis made of Korean rice harvested in 1997 and Chinese rice were higher than those made of other rices. Yield of reducing sugar by $\beta$-amylase reaction was highest in Baiksulgi made of Korean rice harvested in 1998 and lowest in Baiksulgi made of Thai rice. And the value decreased less than half of initial value after 24 hour storage. Adhesiveness of Baiksulgi made of Thai rice was zero and cohesiveness, chewiness and gumminess of that were very low. This results showed that Baiksulgi made of Thai rice was lack of chewy texture and this trend was more apparent as the storage time increased. In sensory tests, Baiksulgi made of Chinese rice had most yellowish color and that made of imported rice such as Chinese and Thai rice had more coarse texture than that made of domestic rices. off odor was lowest in Baiksulgi made or Korean rice harvested in 1997 and sweet taste was lowest in that made or Thai rice. Hardness adhesiveness, moistness and chewiness of Baiksulgi made of domestic rices were much higher than those made of impoted rices, and these results showed that Baiksulgi made of domestic rices had acceptable texture. Baiksulgi made of Thai rice showed the lowest acceptability due to lack of above textural characteristics and it was needed to add the material to modify the texture of that.
