  • Patent number: 7935373
    Abstract: Packaged meat products, methods of packaging meat, and systems for packaging meat. With respect to packaged meat products, one particular embodiment of a packaged meat product comprises a container having a low gas permeability and an enclosed interior volume. The packaged meat product further includes a meat product enclosed within the interior volume of the container and a modified atmosphere comprising not greater than about 10% carbon monoxide within the interior volume of the container. The meat product has a first volume less than the interior volume, and the modified atmosphere has a second volume such that a volume ratio of the second volume to the first volume is not greater than approximately 1:1.

  • Publication number: 20090297667
    Abstract: A product packaging comprises a base, a lid, a meat product, and a gas within a space between the base, the lid, and the meat product. The base and the lid form a cavity having a first volume. The meat product has a first color and a second volume. The second volume is smaller than the first volume. The cavity is configured and arranged to receive the meat product. The space has a third volume that is the difference between the first volume and the second volume. The gas within the space comprises no greater than 30% carbon monoxide, and at least one of the base and the lid has an oxygen transmission rate of 0.1 to 15 cc of oxygen per package in 24 hours so that in 18 to 90 days the first color of the meat product has noticeably changed to a second color.

  • Patent number: 4812320
    Abstract: The process for shaping and slicing primal meat cuts and then packaging the slices to increase the shelf-life thereof includes crust freezing the primal cuts to a depth of approximately 3/8 to 1/2 inch. The crust frozen primal cuts are then tempered for a period of time until the internal temperature reaches approximately 26.degree.-28.degree. F. and the tempered cuts are shaped in a molding press. The shaped primal cuts are then sliced, placed in a tray, and a gas pervious film is applied skin-tight to the slices and the upper surface of the tray. The packages are then frozen before shipment to retain outlets.
