Freeze-thaw stability of 8% dried basis of native and selected modified rice starch pastes subjected to five freeze-thaw cycles at thawing conditions of 30 C for 1 h is illustrated in table 5. It could be seen that native rice starch and modified rice starches showed similar patterns with highest % syneresis in the first cycle and then % syneresis gradually decreased to the fifth cycle. Native rice starch showed the decreasing of % syneresis from cycle 1 to cycle 5 of 28.86%, 22.26%, 10.61%, 1.25% and 1.31%, respectively. The % syneresis of modified rice starch with 4% STPP was decreased from cycle 1 to cycle 5 of which confirmed the occurring of phosphorylation reaction.
