Nitrogen Generators for Potato Chips and Snack Packaging
Oftentimes when people crave a salty and delicious snack, the first thing they reach for is a bag of potato chips. Potato chips are a ubiquitous snack option because they’re tasty, satisfying, cheap, and convenient. A common complaint about chips, however, is that half the bag is usually filled with air. There’s actually a very good reason for that. It’s not just air. It’s nitrogen gas and it helps preserve the freshness and shelf life of your favourite salty snacks, so they always taste great and stay crispy.
Why Is Nitrogen Gas Preferred for Chips and Snacks?
What’s so special about nitrogen gas? Nitrogen gas is used to displace and completely remove ambient air containing oxygen and moisture from the inside of food packaging. Oxygen exposure causes food to spoil faster and can significantly reduce its shelf life.
One of the main reasons nitrogen is the gas of choice for the food packaging industry is because of its uniquely inert qualities. That means nitrogen is completely undetectable to the senses and won’t alter or interact with the taste, smell, or appearance of the food itself. All nitrogen does is help preserve the original state of freshness of the food in a completely enclosed space. Once the packaging is opened and oxygen is allowed to get into it, nitrogen escapes and the food spoiling process begins.
If you leave chips or other snack foods out long enough, you’ll notice they start to soften and get stale. That’s because of the humidity in the air. The oils and fats in snack food can even start to get rancid from reacting with oxygen in ambient air if left exposed for a longer period of time.
