ABSTRACT:
Methods and containers for preserving a product such as a respiratory product having an internal vapor pressure. The product is placed into an enclosure, and the enclosure is sealed and pressured with appropriately humidified air or other suitable oxygen containing gas to a positive pressure with respect to ambient pressure to provide a vapor pressure greater than or at least equal to the internal vapor pressure of the product. The volume of the product in relation to the volume of the enclosure and the pressure are such that the enclosure has free air space sufficient to prevent the onset of an anaerobic condition for substantially the storage period of the product assuming the enclosure is maintained approximately at a predetermined temperature. The temperature of the enclosure may be controlled, and may be maintained below the normal freezing temperature of water, and preferably below the normal liquid to solid phase change temperature of the product, but is maintained above the liquid to solid phase change temperature of the product under pressure in the enclosure. Various pressurized packaging methods and structures also are disclosed.
