Abstract
A method comprises subjecting ant oxygen scavenger to actinic radiation; and then optionally storing the oxygen scavenger in a container, the container configured such that the oxygen scavenger exhibits no substantial oxygen scavenging activity while inside the container. The dosed oxygen scavenger can later be removed from the container, if stored therein, subjected to a second dose of actinic radiation to trigger the oxygen scavenger, and used in packaging oxygen sensitive products. A stored oxygen scavenger, untriggered, is also disclosed.
