Early indica rice was heat-moisture treated at different temperature (90 degrees C, 100 degrees C and 110 degrees C) for 3 h, 5 h and 7 h at a moisture content of 28%, respectively. The effects of heat-moisture treatment (HMT) on the amylose content, pasting properties, texture properties, solubility and swelling power of early indica rice were studied. After HMT at 110 degrees C for 7 h, the amylose content of early indica rice increased from 25.2% to 30.6%, and its pasting temperature increased from 80.1 degrees C to 92.2 degrees C; the peak viscosity, trough viscosity and final viscosity were all decreased significantly. Both the solubility and the swelling power of early indica rice starches decreased after 110 degrees C 7 h heat-moisture treatment. The gel hardness of early indica rice increased significantly, but the adhesiveness decreased after HMT. (C) 2013 Elsevier Ltd. All rights reserved.
