11849745 · 2023-12-26 ·

A meat-packaging procedure and a machine for packaging meat cuts for long-term storage is operated at temperatures of between 28 and 42 F. The process includes sealing meat cuts or full poultry birds or bird pieces within a master bag containing (i) oxygen scavenger materials capable of reducing the residual oxygen content of the atmosphere within the bag to 0 ppm within 96 hours of sealing, and (ii) a CO2 generator capable to generate CO2 in the amount of at least 100 mL per pound of meat or poultry within 7 days of sealing. Gas is injected into the master bag to form a CO2-rich storage environment of at least 50% CO2. For meat trays containing meat with poor color stability, oxygen scavengers are preferably placed within the meat trays. For cuts with good color stability, the oxygen scavengers may be placed outside the meat trays.

METHOD AND APPARATUS FOR EXTENDING SHELF-LIFE OF MEAT & POULTRY
20200315220 · 2020-10-08 ·

The current invention covers an improved meat-packaging procedure and machine for packaging meat cuts for long-term storage at temperatures of between 28 and 42 F. The process includes sealing meat cuts or full poultry birds or bird pieces within a master bag containing (i) oxygen scavenger materials capable of reducing the residual oxygen content of the atmosphere within the bag to 0 ppm within 96 hours of sealing, and (ii) a CO2 generator capable to generate CO2 in the amount of at least 100 mL per pound of meat or poultry within 7 days of sealing. Gas is injected into the master bag to form a CO2-rich storage environment of at least 50% CO2. Depending upon the gas-volume and oxygen scavengers design in the master-bag to maintain diffusion, the CO2 generators may not be needed in the master-bag. The over-wrap of the meat or poultry trays, if meat or poultry are packed in trays, can be perforated so that gas exchange occurs within the master bag between the interior and exterior of the meat tray to absorb the residual oxygen inside the meat trays. For meat trays containing meat with poor color stability, oxygen scavengers are preferably placed within the meat trays. For cuts with good color stability, the oxygen scavengers may be placed outside the meat trays. Meat can be stored by this system for up to 10 weeks and up to twelve days of retail display life. Poultry can be stored for 28+ days by this system. Poultry can be treated with PAA or without PAA and can either be air-chilled or water-chilled with or without PAA: in both instances substantial shelf-life extension is obtained. PAA treated poultry tend to show high microbial growth when compared with non-PAA treated poultry.
