Abstract
A method for deep vacuum packaging of a food product and a system for implementing this method. The food product and at least one additive are placed in a mixing device. The mixing device is evacuated and its contents are mixed to ensure a penetration of the additive(s) in the food product and to outgas the mixture until an absolute pressure is less than or equal to 30 mbar. The temperature of the food product is less than the boiling temperature of the liquid and the additives contained therein at a particular pressure. At least a portion of the mixture cold blanched is packaged in a tight container. The container is optionally pasteurised/sterilized in a short time by controlling the pressure and temperature conditions such that the container does not open or become crushed under the effect of a pressure difference between the inside of the container and the autoclave.
