ABSTRACT:
A method for the cooking and vacuum packing of food includes placing food that is to be cooked and vacuum packed inside a container; passing the container into a microwave tunnel which is suitable for the application of microwave energy to the container and food for the heating and cooking of the food inside the container; subjecting the container containing the food to microwave energy to heat the food; and ceasing the application of microwave energy such that the venting opening closes and, as the container cools, steam therein condenses, whereupon a vacuum arises inside the container. The cooking and vacuum packing take place in the same operation in the container and the container is flexible such that it molds itself to its contents when a vacuum arises in the container.
