Abstract
An oxygen scavenging composition composed of a carrier and a metal coated, inert, porous particulate material having the metal substantially in a zero valence state. The composition is contained within the interior cavity of a container to scavenge oxygen therein. The composition may form at least a part of the interior surface of the container or be present therein in the form of a film, mat, sachet or ceramic.
