The present study was undertaken to determine the effect of hydrothermal treatment on milling characteristics of finger millet (PPR 2700, Vakula). Finger millet grains were soaked in two different water temperatures of 30 °C and 70 °C with 24 and 1 hour 45 minutes soaking times respectively. Treatments were followed by steaming at 1, 1.5 and 2 kg cm-1 pressures. The samples were dried at 40 ºC and equilibrated to two different final moisture contents of 12 and 14% (wet basis). Hydrothermally treated samples were milled using rice polisher and the product was classified into head rice, broken and seed coat matter. From the milling studies, it was observed that the increase in soaking temperature and steaming pressure increased milling yield. Hydrothermal treatment of finger millet increased the hardness of the grain and this resulted in improved milling yield upon milling. The treatment with soaking temperature of 70 °C, steaming pressure of 2 kg cm-2 dried to a final moisture content of 14% was found to be the best with milling yield, broken percentage and seed coat percentage of 87.80%, 4.44% and 7.68% respectively.
