ABSTRACT
Gelatinization parameters of selected starch materials such as flour grits, native starches, and modified starch were determined thermomechanically, by measuring the respective torque values. The highest torque [Nm] was found to occur during gelatinization of rice grits, potato starch, and distarch phosphate. Pure starches required less time to gelatinize, compared to flour grits. Grits of larger grain sizes required higher initial temperatures (tP) to gelatinize. The highest gelatinization rates were observed in potato starch and distarch phosphate.
Key words: starch, grits, gelatinization, torque.
