Insert Extends Shelf Life Of Package Foods

摘要

Emco Packaging Systems has developed an insert consisting of a palladium catalyst and a gas permeable membrane that offers a more efficient method of scavenging oxygen in filled bottles or packages to extend shelf life.The insert is used in a modified atmosphere gas mix containing hydrogen.The palladium uses the hydrogen to bind oxygen present in the headspace of a filled bottle or package,creating water.The water formed from the process is held trapped between the membrane and a plastic substrate the company developed to put in bottle caps.The palladium keeps working until all hydrogen is consumed.
