GALVANIC PACKAGE FOR FRUITS AND VEGETABLES AND PRESERVATION METHOD

摘要

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.

1. A package for fruits and vegetables having galvanic functionality, said package comprising:
a storage unit formed of a nonmetallic substrate and having at least one internal surface; and a first metal deposited on the at least one internal surface of the storage unit, a second metal in the storage unit, wherein the first metal and the second metal have different galvanic properties, one of the first metal and the second metal being sacrificial.
