This study was carried out to know whether recommended temperature-Time course until boiling of cooked rice is for the sake of the uniform gelatinization of rice starch or for the water absorption of rice grain.First, homogenized rice, instead of rice grain, was employed to avoid the influence of the rice tissues, and the period necessary to attain the boiling point was setted to 5,10,20 and 40 min., respectively, from the initial temperature of 30°C, and as the results no differences were confirmed between these samples.Second, the texture of cooked rice, which was cooked under the usual cooking conditions except the cooking times, was compared. When cooked under slow temperature increase, like as the case of over 20 min, for the boiling, the longer the cooking time is, the less homogeneity in the texture and the difference of water absorption between the top and the bottom in a pot was significant. On the other hand, in the case of shorter cooking time, like as 5 min, to attain the boiling point, it seemed to be too short to get enough water content necessary to gelatinize the starch at the center of the rice grain.From these results, as the cooking method of rice, to adjust the temperature increase so as to attain to boiling point after 10 min. cooking seemed to be not based on the matter of the gelatinization of starch but on the point to obtain the uniform water absorption in the pot.
