Abstract: The presently disclosed subject matter is directed to a system and method that allows on-demand oxygen generation within a package. Particularly, the disclosed package incorporates a mass of an oxygen generating material within the interior or exterior of the package. The oxygen generating material is contained by some means, for example, in a cartridge, pouch, sachet, or other similar article separate from a packaged product. For applications with fresh red meat, at the time the package is ready for display, oxygen generation is initiated to increase the oxygen concentration within the package interior, thereby allowing blooming of the red meat.
