Modified atmosphere packaging (MAP) is the process of using high purity nitrogen to eliminate oxygen from food packaging in order to prevent spoilage and preserve freshness. Food products like chips, nuts, dairy, produce, and meat all benefit from MAP when it comes to preserving quality and increasing shelf-life. For a process like MAP where there is a constant need for high purity nitrogen, investing in an on-site nitrogen generator can significantly reduce the costs and time associated with the packaging process.
