Food preservation can include depositing dry ice and food within packaging. The packaging can include a flexible liner defining a wall aperture and an internal chamber. The internal chamber can receive the deposited dry ice and food and have an internal atmosphere. The packaging can include a check valve mounted to the flexible liner and covering the wall aperture. The check valve can be configured to occupy: (i) a closed state blocking fluid communication between the internal chamber and ambient via the wall aperture and (ii) an open state enabling fluid flow from the internal chamber, through the wall aperture, and into ambient.

The present invention relates to a refrigerator designed to reduce the deterioration rate of stored items, such as food, fruits, vegetables, meat, flowers, and plants, within the storage compartment using plasma and a photocatalyst. Specifically, the invention performs filtering with a photocatalyst and plasma sterilization on the air in the storage compartment to decompose ethylene gas and other substances, thereby reducing the deterioration rate of stored items and extending their storage period. The invention utilizes a compact high-density plasma generator with discharge electrodes and ground electrodes arranged in multiple cells. Plasma is uniformly and multidimensionally generated in the air within the storage compartment, decomposing ethylene gas to slow the deterioration rate of food, fruits, vegetables, meat, flowers, and plants, and extending their storage period.
