  • Patent number: 6746630
    Abstract: The claims are drawn to a method of detecting seal breakage or incomplete seal formation in a package, said method comprising the steps of: (i) providing said package, prior to sealing, with a strip or ring of an indicator comprising an oxygen scavenging composition which includes a source of labile hydrogen or electrons and at least one reducible organic compound, wherein said strip or ring is located on an internal surface adjacent to where a seal is to be formed, (ii) treating the strip or ring with electromagnetic energy so as to reduce the reducible organic compound to a reduced form which is oxidizable by ground state molecular oxygen regardless of the presence of a transition metal catalyst and such that, when oxidized, there is a detectable change in a characteristic of said composition selected from the group consisting of: colour, fluorescence emission and UV-visible, infrared or near-infrared absorption, (iii) subjecting said package to a sealing process intended to seal the package, and (iv) detec

  • Patent number: 6123901
    Abstract: Oxygen scavenging materials particularly for use in the food industry, are disclosed. The oxygen scavenging materials comprise at least one compound oxidizable by molecular oxygen, wherein the at least one compound is contained within an oxygen impermeable compartment(s) or microcapsule(s) which may, as required, be broken or otherwise rendered oxygen permeable by application of heat, electromagnetic radiation, mechanical pressure or stress, or by hydration.
