Abstract
A package for fruits and vegetables having galvanic functionality is formed by using two or more metals with different galvanic activity properties on the surface of a nonmetallic substrate. The metals may be deposited electrolytically, by vacuum, autocatalytically, or by other methods. The metals are selected to create a galvanic reaction after the package is filled with a low pH food product and its associated liquids, juices, brine, etc. The package may extend the shelf-life of the food product contained therein, for example, by making metal ions available to the food product.
