Abstract
A method for packaging non-liquid food products, particularly those sensitive to oxygen, such as vegetables, in a container with a low oxygen content, the container including an opening. The method includes the following steps: the container is filled with the products, in a non-controlled atmosphere; the air is removed from the container by filling same to capacity with a liquid; the full container is placed in a non-oxidizing atmosphere formed by at least one non-oxidizing gas; the liquid is fully or partially emptied from the container in a non-oxidizing atmosphere while the food products are kept in the container, such that the at least one non-oxidizing gas replaces the liquid in the container; and the above-mentioned container opening is closed in a gas-tight manner in a non-oxidizing atmosphere. A unit for carrying out the method is also described.
