Procedure for the preparation of food products in an autoclave in a container formed by a composite material in flat form with a layer of crosslinked outer polymer of color that can be obtained by gravure printing

摘要

A process for the production of a closed container (3) that closes an interior space (1) with respect to an environment (2), filled with food products from at least one composite material (7) in flat form presenting the minus one edge (4), which contains the steps: a) facilitation of the composite material (7) in flat form, which contains a1. at least one crosslinked outer plastic paint layer (9) containing a dye (20), the plastic paint layer (9) containing a polyaddition product; a2. a support layer (6); and a3. a layer of thermoplastic plastic (16); b) conformation of the composite material (7) in flat form with the obtaining of an open container (14), pointing the plastic paint layer (9) towards the environment (2) and the plastic layer (16) towards the interior space (one); c) filling the open container (14) with a food product; d) closing of the container (14) open with obtaining the container (3) filling closed; e) preservation of the food product in the container (3) closed filling in a pressure chamber under a chamber pressure of more than 1 bar at a temperature in a range of more than 100 to 140 ° C in the presence of water vapor.
