Abstract
This study was carried out to investigate physiochemical properties and factors related with eating quality in the rice and paddy rice with different storage methods. As storage period was longer and temperature was higher, the b values of chromaticity and degree of fatty acid were increased, and the b value of room temp. was higher than that of low temp. In the varieties, the b value of Samcheonbyeo was the highest among varieties. also b value of Gancheokbyeo and Sae-gyehwabyeo were more increased than those of Dongjinbyeo and Hojinbyeo. Toyo meter values were significantly different according to storage temperature and period. Toyo meter values in storage of low temp. small decreased from 8 month after storages and that of loom temp. was severe decreased from 2 month after storages. In storage of low temp, Toyo meter values in storage of low temp. $(5{\sim}10^{\circ}C)$ was the lowest, and those of the early varieties were the most decreased. Degree of fatty acid of brown rice was increased from 2 month after storages and those of low temp. was severe increased. So, they made rice quality and eating quality to be deteriorated.
