PROBLEM TO BE SOLVED: To provide processed cooked rice easy in production management, capable of preserved at room temperature, giving a small amount of just-cooked rice or ingredient-added seasoned rice in a short time with simple devices and capable of responding to wide variety of uses.SOLUTION: The processed cooked rice is provided by adding water at a weight ratio of 200%-100% to rice having rice starch at least partially pregelatinized to have a moisture value within of range of not less than 0.1 wt.% but less than 15 wt.%, and filling the obtained to seal in a container, the pregelatinized rice in the container is heated for 10-30 min at a temperature of 85°C-125°C to obtain cooked rice when served, so that the supply of the pregelatinized rice provides with simple devices such as a steamer a necessity minimum of just-cooked rice or ingredient-added seasoned rice because easy in control on the processed cooked rice production procedure owing to low moisture value of the pregelatinized rice.COPYRIGHT: (C)2012,JPO&INPIT【課題】生産管理が容易且つ常温保存が可能で、簡易な設備で少量ずつの炊き立てご飯や具材入り炊き込みご飯を短時間で得、多種多様の用途に対応出来る加工米飯を提供する。【解決手段】水分値が0.1重量%ないし15重量%未満の範囲内で米澱粉の少なくとも1部をアルファー化した米に、水を重量比で200%ないし100%の割合で添加し、これらを容器に充填密封してなるものであり、利用時に85℃ないし125℃の温度にて容器内のアルファー化米を10分間ないし30分間加熱して、炊飯米を得ることで、上記のアルファー化米が供給されれば、アルファー化米の水分値が低いから加工米飯の生産過程での管理が容易で、蒸し器など簡易な設備で必要最小限ずつの炊き立てご飯や具材入り炊き込みご飯を得ることが出来る。
