The disclosure relates to a method and an apparatus for heat-treating a food which is packed in a container (1, 14) of flexible or foldably formable packaging material for the purposes of extending the shelf life of the food. In order to accelerate the heat treatment, the container (1, 14) is disposed such that it is, during the heat treatment proper, caused to adopt a first position in which the distance between opposing side wall panels (7) and, thereby, the layer thickness of the packed food, is reduced to a minimum, taking into account the volume of the food and the surface of the packaging material, as well as the shape of the container proper. After completed heat treatment, the container is brought to a second position in which the shape of the container corresponds to that shape in which the container (14), with its packed, heat treated food, is to be distributed, sold or used.
