The flour with high damaged starch increased water retention capacity (Nishita & Bean, 1982). Water binding capacity, SP and solubility at 80 C of rice flours are shown in Table 1.Water binding capacity and solubility of HP-80 were 162.32 and 4.09%, and those of HP-200 were 196.50 and 6.11%, respectively. Water binding capacity and solubility increased when particle sizes decreased, but SP values stayed in the range of 7.48e7.94. The color values of the rice flours are also shown in Table 1
