Food product i.e. foie gras, containers sterilization method, involves closing openings of containers so as to ensure degassing at level of one of openings possessing obturation with degree that is adjusted to be less than determined value

摘要

The method involves closing two openings (3, 3 ') of containers (1) by corresponding lids (4, 4 ') at different sealing degrees during a preliminary preparatory phase so as to ensure main or exclusive degassing at a level of one of the openings possessing an obturation with the slightly increased sealing degree. The sealing degree is adjusted to be less than a determined maximal threshold value. The sealing at the level of each opening is obtained by crushing a circumferential joint using the lids that are made of glass or metal. An independent claim is also included for a sterilizable container for a food product, comprising a hollow cylindrical body.
