Nitrogen Generators are a cost-effective and convenient source of Nitrogen gas for maintaining coffee freshness in packaging from roasting to brewing. Controlling the exposure of coffee beans to oxygen is critical to taste and freshness. Coffee beans that are not properly preserved after roasting will lose too much carbon dioxide, which accelerates staling and allows volatile aromas to escape, weakening flavor.

Packaging Coffee with Nitrogen Flush

Adding a Nitrogen gas flush to the process of packaging ground or whole bean coffee soon after roasting pushes residual oxygen out of the packaging. The pressure of the Nitrogen gas inside the sealed package promotes proper aging of the coffee by slowing down the degassing or loss of CO2. This also traps the volatile aromas within the space, improving the flavor and creating a stable atmosphere for long term storage. The effect is to maintain freshness for long-distance transport of bulk coffee, and extend shelf life once the packaged coffee reaches the retailer.
