PURPOSE:To excellently prevent mutual integration of solid food in a container and to produce the solid food packed in a container causing neither browning on the top of the food nor scorching, by bringing the top of the solid food into contact with a cover part of the container during heating under pressure. CONSTITUTION:A solid food such as boiled rice, boiled beans, noodle foods, etc., packed and sealed in a rigid or semi-rigid and heat-resistant container constituted in such a way that the side wall part, bottom part or cover part of the container is temporarily deformed by heating under pressure in a manner where air content of the container after the packing and sealing is 40-85vol.%, preferably 45-80vol.% based on total volume of the container and >=about 60% total area on the top of the solid food is brought into contact with the cover of the container. Preferably heat treatment under pressure is carried out under control in such a way that time for pressure drop outside the container is set behind starting point of cooling. |
