PROBLEM TO BE SOLVED: To provide a method for producing aseptic packaging rice in which the reliability of sealing can be increased, and a container for aseptic packaging rice.SOLUTION: Rice is charged to a container having an opening at the upper part, after press heating treatment, baking water is fed thereto, a film-shaped sealed member is joined to the first annular region along the whole circumferential face of the periphery part of the container to seal the container (first seal), and cooking is performed. During the cooking, by the pressure at the inside of the container, in the optional part of the first annular region, the peripheral part of the container and the sealing member is separated, and the pressure at the inside of the container is released. Next, as the container is covered with the sealing member, a steaming step is passed through. Thereafter, the sealing member is joined to the second annular region different from the first annular region, the container is sealed (second seal).COPYRIGHT: (C)2016,JPO&INPIT【課題】密封の信頼性が高められる無菌包装米飯の製造方法及び無菌包装米飯用容器を提供することを目的とする。【解決手段】上部に開口を有した容器に米を入れ、加圧加熱処理後、炊き水を供給し、フィルム状の密閉部材を該容器の周縁部の全周面に沿った第1環状領域に接合することにより該容器を密閉し(第1シール)、炊飯を行う。炊飯中、該容器内の圧力により上記第1環状領域のうちの任意部分において該容器の周縁部と該密閉部材との接合が離れ、該容器内の圧力を開放する。次に、上記密閉部材で上記容器を覆ったまま、蒸らし工程を経る。その後、上記密閉部材を、上記容器の周縁部の全周面に沿った、前記第1環状領域とは異なる第2環状領域に接合することにより該容器を密封する(第2シール)。【選択図】図1
