We love our snacks and we like them fresh and healthy. That means minimal preservatives, yet no loss of freshness, and a long shelf life. Is it possible to have it all? With the help of nitrogen, we come very close. This inert gas has long been the choice of premium food and beverage manufacturers. It's what gushes out of your favourite pack of chips
when you pull it open. It's what keeps your coffee
pods fresh for your morning cup. It's what keeps your wine
bright well after it's been popped. The nitrogen gets in with the help of a process known as MAP
(Modified Atmosphere Packaging) which packs snacks like a mini-earth with an atmosphere that keeps its contents in prime condition.
But it's not enough to get nitrogen into the package—the gas must be food-grade compliant. It must be free of contaminants such as dust, oil, water, gases, and micro-organisms. This is not just necessary for a high-quality product, it's necessary for the protection of customer health and for preserving the credibility and reputation of your business and brand. Food air safety is paramount. In fact, the ISO (International Organization for Standardization), SQF (Safe Quality Food Institute), and BRC (British Retail Consortium) have identified compressed air used in packaging and processing as a possible threat to food air safety.
