Technical Examples

Systems and methods for preserving a perishable material sensitive to oxygen and bacterial spoilage are taught. The systems in some embodiments comprise a pressurized source of a first gas other than oxygen and a container for the perishable material, the container having a sealable lid, a passage including a one-way valve through the lid connected by a gas conduit to the pressurized source, and a mechanism for venting the container. In various embodiments oxygen exposure to the perishable material in the container is diluted by at least one cycle of pressurizing the container with the first gas other than oxygen, and then venting the container. In some embodiments oxygen dilution is by vacuum.
