抄録

We used 20-60% juice of Japanese summer orange and Amanatsukan in place of water on rice cooking, and exaimined about the effect of this method on the color, taste and quality of cooked rice. The results are as follows.:
1) There were on adverse effect on the color and taste by cooking with juice and the rice cooked with adequate amount of juice was acceptable in sensory evaluation.
2) The cooked rice with juice showed low hardness, high adhesiveness and was glossy. By microscopical observation, the thick matter was at the surface of cooked rice grains. It was suggested that there is the relation between this matter and adhesiveness and glossiness. It was considered that we can make use of these characteristics to the aged rice stored for a long time and the low-adhesive rice.
3) As for state of acid permeation into the cooked rice grains, large quantity of acid was contained around the surface. It is remarkable for the cooked rice with more juice. It was considered that the surface state of cooked rice was changed by acid, and this fact appeared to difference on the texture.
