Keeping Food Fresh with a Nitrogen Generator

Pffftt! You pull open the bag of ground coffee you just bought and out comes a waft of unmistakable aroma that wakes you up before the grounds even hit the filter basket on your coffeemaker.

Despite the fact that the bag sat on the shelf of your grocery store for weeks or longer, the coffee is as fresh as the day it was packaged.


Why? Because it's not air that is released as you open the bag. The air has actually been replaced with an inert gas, typically Nitrogen, to limit the oxygen that comes in contact with the coffee. This is called Modified Atmosphere Packaging (MAP), which increases the shelf life of minimally processed foods without the need for vacuum packaging, preservatives, or freezing.

MAP reduces the oxygen in packaging to below 1% to prevent spoilage and preserve properties such as aroma, crispness, color, flavor and texture of packaged foods. It is used for all types of foods including potato chips and other snack foods; cooking oils; nuts and dried fruits; cheeses; wine bottling and many other food and beverage categories.

Nitrogen Generators simplify the MAP process by making Nitrogen available on demand at low cost, either as the primary inert gas or mixed with other gases. A Nitrogen Generator eliminates long term gas contracts, constantly change out tanks and cylinders, and the need for hazardous storage.

Will a Nitrogen Generator make your packaging process easier, more convenient, and lower your costs? Contact South-Tek Systems today and take a fresh approach to your Nitrogen Supply: 888-526-6284.
