Specific heat and gelatinization temperature of long-grain basmati rice were measured using differential scanning calorimetry (DSC). The value of specific heat of brown rice sample ranged between 1.27 to 4.83 kJ/kg K, with temperature varying from -10 to 150C range, whereas the same varied from 1.23 to 4.34 kJ/kg-K for paddy for moisture content of 13 % and 12.4 % (wb), respectively. The gelatinization temperature range of has been found to be between 73-77 C for the powdered milled rice sample.
