Abstract:
A package for a product comprising: means for supporting or retaining the product; and a moisture-activated oxygen scavenging composition comprising a polymeric carrier permeable to both oxygen and water or water vapor, an ascorbate compound which is capable of reacting with oxygen after activation with water or water vapor; and a catalyzing agent in an amount effective to increase the rate of reaction of said ascorbate compound with oxygen which is present inside the package, said ascorbate compound and said catalyzing agent being relatively uniformly dispersed as separate components throughout said polymeric carrier; said oxygen scavenging composition being dormant and substantially non-reactive with oxygen until moisture-activated, said oxygen scavenging composition being in contact with the product or the environment between the product and the package for scavenging oxygen therefrom, so as to avoid or reduce detrimental effects of oxygen upon the performance, odor or flavor properties of the product.
