Abstract
The invention relates to a method for packaging a liquid product (1), such as a food product, and, in particular, a product sensitive to oxygen, in a container (2) with a low oxygen content, said container including an opening (3). The method of the invention comprises the following steps: the air is removed from the container by filling same to capacity with the liquid product in a non-controlled atmosphere; the full container is placed in a non-oxidizing atmosphere formed by at least one non-oxidizing gas; the liquid product is partially emptied from the container in a non-oxidizing atmosphere, such that the at least one non-oxidizing gas replaces the product discharged from the container; and the above-mentioned container opening is closed in a gas-tight manner while the container is partially full of the liquid product in a non-oxidizing atmosphere.
