Research Abstract

With increasing the atmosphere temperature, the quantity of rice harvest decreases, and the taste of cooked rice is bad. In the present study, the physicochemical properties of koshihikari and koshiibuki grown at Niigata prefecture were investigated to clarify the mechanism that the cooked rice grown at high temperature has a bad taste, and to build a new method based on the image analysis which evaluates the taste of cooked rice. When the area of white-core in the rice grain increased, the weight of one thousand brown grains, the length of one brown grain, and the hardness of cooked rice decreased. The shape of starch granule in the white-core rice grains was more circular than that in the control.
