Photo-regenerable oxygen scavenging packaging is generally disclosed. Some example embodiments may comprise tantalum oxide and/or manganese oxide arranged to act as a photo-regenerable oxygen scavenger. The tantalum oxide, if present, may operate as an oxygen scavenger when the tantalum oxide exists as tantalum (IV) oxide. Subjecting the tantalum oxide to light may transform at least a portion of the tantalum oxide existing as tantalum (V) oxide to tantalum (IV) oxide. The manganese oxide, if present, may operate as an oxygen scavenger when the manganese oxide exists as manganese (II) oxide. Subjecting the manganese oxide to light may transform at least a portion of the manganese oxide existing as manganese (III) oxide to manganese (II) oxide. Some example containers may include a structure defining an interior volume and a photo-regenerable oxygen scavenger disposed in fluidic communication with the interior volume. |
