The sensory and instrumental characteristics of warm and cool cooked rices with pressure and electric cookers were examined. The types of rice varieties tested were Choucheong (traditional rice variety) Samgang and Seogwang (high-yielding rice varietis) The result of sensor evaluation revealed more significant differences in most of appearance, texture characteristics than flavour. The difference of sensory characteristics according to the types of cookers and the warm or cool cooked rices was greatest in Seogwang among three varieties. The instrumental measurement of cooked rices using instron showed that the difference between types of varieties and cookers was more clearly in cool cooked rices than warm ones. Especially hardness in instrumental characteristics revealed highly signficant difference. With regard to the correlation between instrumental and sensory characteristics, hardness had a significantly high correlation with texture while others had low ones.
