PROBLEM TO BE SOLVED: To provide a packaging method of food capable of airtightly packaging the food without attaching bacteria to the food after sterilization even if a clean room which causes a steep rise of equipment cost and the restriction of an installation space is not introduced.SOLUTION: The packaging method of the food for airtightly closing a food-contained container after sterilization which contains the food into a container body of which the upper surface is opened includes: a step of bringing the interior of the container containing a primarily processed food to a positive pressure state while or after the container containing the primarily processed food in which the opened part of the container body in the container containing the food is covered with a gas permeable film having air permeability is thermally sterilized and a step of laminating an airtight material on an area containing at least the opened part of the gas permeable film in the container containing the primarily processed food in the positive pressure state so as to airtightly close the interior of the container containing the primarily processed food.COPYRIGHT: (C)2013,JPO&INPIT【課題】設備コストの高騰や設置スペースの制限の原因となるクリーンルームを導入しなくても、殺菌後の食品に雑菌類を付着させることなく該食品を密閉包装することのできる食品の包装方法を提供することを課題という。【解決手段】上面が開放した容器本体に食品を収容した殺菌後の食品入容器を密閉する食品の包装方法であって、前記食品入容器における容器本体の開放部分を通気性を有する気体透過性フィルムで覆った一次加工済食品入容器を加熱殺菌中又は加熱殺菌した後に、該一次加工済食品入容器の内部を陽圧状態にし、該陽圧状態の一次加工済食品入容器における気体透過性フィルムの少なくとも前記開放部分を含んだ領域に気密性材を積層し、前記一次加工済食品入容器内を密閉するようにした。【選択図】図3
