PB1121 paddy was soaked in water at seven different temperatures (40oC-80oC) till it achieved desired moisture. Soaking showed significant effect on physical characteristics of PB1121 rice. Soaking altered the length, breadth, thickness volume, surface area, equivalent diameter and sphericity of paddy grain. Un-soaked grains had bulk and true density as 508.60 and 1138.8 kg m-3, respectively, whereas that of soaked grains varied from 511-527 and 1188-1238 kg m-3, respectively. Head rice yield (HRY) of un-soaked rice was 42.12% whereas that of soaked rice varied from 50.21%-53.05%. Soaked grains were harder than the un-soaked grains. Un-soaked rice had lightness and redness values as 60.26 and 6.47, respectively but, with soaking temperature, lightness decreased (9.56%-16.23%) whereas redness increased (9.58%-25.50%). Soaking
imparted reddish color to the grain, but not yellowness. Based on grain color, hardness and HRY, it was inferred that 65oC to 70oC temperatures would be appropriate for soaking of PB1121 paddy.
