This was attribute to a fact that the main component in waxy rice was amylopectin that was more sensitive to heat and pressure than amylose (Hu et al., 2011). The pressure difference, therefore, was easier to widen the channels for the soaked waxy rice grains. The channels could be swelled by heat air during cooking. These results suggest that the higher sensitivity of rice components to soaking pressure was responsible for generating the homogeneous network microstructure. This network might produce the lower hardness and the higher springiness of cooked waxy rice.
