Abstract:
A method of removing an entrained amount of oxygen in a sealed package containing an oxidisable product comprising the steps of:(a) dispersing in a solution of a water-insoluble adhesive material a particulate catalyst which has high activity for combining hydrogen and oxygen; (b) applying the dispersion to a predetermined area of the inside surface of the material from which the package is made; (c) evaporating solvent from the dispersion in such manner that the catalyst particles become partially encapsulated on a surface of the dried adhesive; and (d) introducing a mixture of an inert gas or gases and hydrogen into the package either before or after sealing of the package, the hydrogen being present in the package in sufficient quantity to react with the entrained oxygen to form water.
