Materials and Methods
Chainat 1 and KDML 105 brown rice were germinated according to the method of Khampang et al. (2009) with a slight modification. Brown rice was soaked in water at room temperature until the root length of rice was 0.5-1 mm. Germinated brown rice was dried at 55°C for 10 hrs and ground to flour in a grinder and passed through a 300 μm (50 mesh) screen. After that germinated brown rice flour was mixed with water at ratio of 3:1, 2:1 and 1:1. The flour were heated at the temperature of 60, 80 and 100°C. To investigate the influence of flour:water ratio and temperature in pregelatinization process on thermal and rheological properties of pregelatinized germinated brown rice flour. Thermal and rheological properties of pregelatinized germinated brown rice flour were determined by using Differential Scanning Calorimeter (DSC) and Rheometer by the method of Kim et al. (1995) and Hagenimana and Ding (2005).
