Several varieties of rough rice that were either stored for an extended period o f time or freshly harvested were conditioned to initial moisture contents rangin g from 10 to 17%. After the individual kernel moisture content distributions wer e measured, the samples were soaked in water at temperatures ranging from 10 to 40 degrees C. The samples were then dried and milled. The bulk critical moisture content, at which head rice yield began to decline due to moisture adsorption, ranged from 12.5 to 14.9%, depending on the variety, harvest moisture content, a nd storage conditions. The kernel critical moisture content, determined from eac h sample from the cumulative kernel moisture content frequency distribution, inc reased with increasing sample initial moisture content.
