The effects of water to rice ratio on the properties of cooked nonwaxy and waxy rice during storage were investigated by sensory evaluation and instrumental test by Instron. The result of sensory evaluation revealed more significant difference in most of texture characteristics than flavour. As the water to rice ratio increased, the moisture content of cooked rice increased and the value of moistness and plumpness increased but that of hardness decreased. Overall eating quality was the highest in cooked nonwaxy rice with 1.4(water/rice) and in cooked waxy rice with 1.2(water/rice). In the case of instrumental test, hardness showed highly significant difference and the value of hardness of nonwaxy cooked rice was greater than that of waxy cooked rice.
