A method and a package for packaging fresh meat in a substantially oxygen-free atmosphere. The package (10) includes a packing tray (12) which is sized for receiving a piece of fresh meat of predetermined cut. The tray (12) is overwrapped with a web of clear pllastic wrapping material (18). The overwrapped tray is ventilated to ensure gas communication between enclosed regions of the overwrapped tray and the outside ambient without blockage due to run off juices from the meat product or shifting of the meat product during transport. A number of similarly ventilated overwrapped trays are then placed within an outer barrier bag (26) which is first evacuated of normal atmosphere and then flushed with a preservation-enhancing gas. The outer bag (26) is then sealed.

L'invention porte sur un procédé d'emballage de viande fraîche en atmosphère sensiblement exempte d'oxygène et sur l'emballage associé. L'emballage (10) comporte une barquette (12) dimensionnée pour recevoir un morceau de viande préalablement découpé. La barquette (12) est enveloppée d'une feuille de plastique transparent (18). La barquette (12) une fois enveloppée est ventilée de manière à assurer le passage du gaz entre les zones sous feuille et l'extérieur sans possibilité de blocage par les jus sortant de la viande ou le déplacement de la viande pendant le transport. Plusieurs barquettes enveloppées ainsi ventilées sont ensuite placées dans un sac constituant une barrière extérieure (26) qui est d'abord vidé de l'atmosphère normale, puis rempli d'un gaz facilitant la conservation, puis scellé.
