Rice variety, "Ilmi" was a major portion of brand rices in Jeonbuk region, and in few portion, there were variety-mixed brands, Shindongjin, Kosihikari, and Hitomebore. Comparing the ratio of head rice of high-quality Jeonbukoriginated brand rice with other domestic brand rices were not significantly different. Head rice ratio and mechanical taste values were not significantly different between high-quality Jeonbuk-originated brand rice and the other domestic brand rices. The contents of protein, moisture, amylose of rice were also not significantly different between them. The quality of high-quality Jeonbuk-originated brand rice was as good as that of other domestic brand rices and had not changed it by period.

There could get difference on the major component related to palatability of rice as country in this study. Comparing with foreign rices. protein content of domestic rice (6.1%) was similar with that of United States, lower than those of Chinese and Thailand. The head rice ratio of the domestic rice was 92%, which was similar with those of Unite State and Chinese but the Chinese parboiled rice was completely cracked during processing. The setback viscosity of domestic rice related to retrogradation was lower than those of the imported rice except United States. The Ad (Adhesiveness / H(Hardness) ratio was higher in the domestic and United States rice.
