Abstract: A method for triggering an oxygen scavenging composition for use in packaging an oxygen sensitive article includes the steps of providing an oxygen scavenging composition comprising an oxidizable organic compound and, optionally, a transition metal catalyst, and exposing the composition to a source of pulsed light wherein each pulse has a duration of between 1 microsecond and 1 millisecond, a frequency of between 0.1 to 100 Hertz, and a total intensity of at least 350 mW/cm2 so that each pulse provides the composition with a dose of UV light of at least 0.1 J/cm2 so as to provide a triggered composition. The triggered composition can be applied to an article so as to provide an oxygen scavenging package. An apparatus and packaging system are also disclosed.

Abstract: A method of reheating a cooked food. First, an unperforated package is provided having an internal pressure of less than about 13.7 psia and enclosing a cooked meat. The package comprises a film comprising an inside film layer adjacent the internal space of the package. The inside film layer comprises one or more polymers selected from polyamide and polyester. The cooked meat is heated while enclosed in the unperforated package to an internal meat temperature of above about 100° F. The method is useful in reducing the warmed over flavor effect that may result from reheating the cooked meat.
