Purpose: The aim of this study was to compare the cooking properties of Bodeurami and Ilmi to promote consumption of rice. Methods: The properties of Bodeurami and Ilmi such as proximate composition, Hunter's color value, water absorption rate, and cooking properties as well as Hunter's color value, texture properties, and sensory evaluation of cooked rice were analyzed. Results: Crude protein, crude fat, and crude ash contents of Bodeurami and Ilmi were higher in brown rice than in white rice. Regardless of rice cultivars, L-value was lower, whereas a and b-values were higher in brown rice than in white rice. The water absorption rate of rice grains was higher in white rice than in brown rice and increased rapidly to 75 min for white rice and 4 hr for brown rice. Cooking properties, water absorption, and expansibility of white rice were higher than those of brown rice, and there were significant differences between Bodeurami and Ilmi. Immediately after cooking and after storage at warm ($70^{\circ}C$) and room temperatures ($25^{\circ}C$), hardness of cooked rice increased after storage, but was not significantly different between Bodeurami white rice and Ilmi brown rice. The sensory evaluation shows that Bodeurami brown rice scored the highest for taste, texture and overall preference. Conclusion: Thus, the results of this study shows that Bodeurami brown rice is characterized by high cooking quality without any mixed white rice, and Bodeurami white rice could be used for the rice processing industry as well as cooked rice.
