Mission-Critical Nitrogen™ Keeps Food Fresh!
Oxygen can be detrimental to food quality – it introduces moisture and deteriorates the quality of the product. Nitrogen is used to reduce the presence of oxygen ensuring freshness and a longer shelf life. Using nitrogen to purge food products of oxygen is a safe practice widely used throughout the food industry.
South-Tek’s N2GEN systems allows you to reliably create Nitrogen from thin air, in- house and on-demand.
Why is nitrogen so important for food processing/packaging?
Nitrogen gas has long been used in the food industry to help preserve the freshness, integrity, and quality of the delivered product. Food manufacturers often use nitrogen purging and nitrogen blanketing to displace oxygen from the atmosphere while processing or storing the food.
Nitrogen gas is also used to provide a pressurized atmosphere that prevents package collapse. Using N2 gas in this way helps ensure that more delicate foods, such as chips and crackers, won’t get crushed in the bags where they’re stored.
Food packaging types include:
Bags, bottles, cans, boxes, plastic, and cardboard containers.
Traditionally supplied as bulk liquid nitrogen, today, factories are replacing bulk N2 with Nitrogen generators as a safe, efficient and cost-effective solution for reliable food-grade mission-critical nitrogen™.

Nitrogen Benefits for Food Applications
From animal feed to gourmet delicacies, ensure food product quality with an N2GEN mission-critical nitrogen™ generator – a cost-effective alternative to high-pressure N2 cylinders or bulk liquid N2. South-Tek’s industrial Nitrogen generators are designed and built to suit each customer’s unique needs with the exact purity and flowrate your process requires.
- Food Packaging: Manufacturers often use nitrogen purging or MAP (Modified atmosphere packaging) to displace oxygen from the package before sealing it closed, in addition N2 provides a pressurized atmosphere that prevents package collapse.
- Food Processing: Nitrogen gas preserves taste, texture, and color during food processing by preventing oxygen from reaching the food and maintaining freshness.
- Food Storage: By creating a storage atmosphere that carefully controls the oxygen and humidity levels, apples, pears, oranges, and other produce can remain fresh and crisp much longer, because the ripening process will be significantly slowed.
- Edible Oils: Whether refined or not, all oils are sensitive to heat, light, and exposure to oxygen. Oils become rancid under these conditions, which affects the taste, smell and clarity of the oil. Nitrogen is used for blanketing, purging and to fill the head space of the bottle.
- Animal Feed Storage: The use of nitrogen gas prevents stored animal feed from going bad by reducing the oxygen level and displacing moisture. Animal feed often has a significant amount of oils in them and Nitrogen is used to protect the feed from going rancid, allowing for a longer shelf life. Nitrogen is also used during the packaging process to open up the bags prior to being filled.
Cost Comparison
Traditionally, buying bulk liquid nitrogen has been the go-to solution for the Heat- Treating industry. With modern nitrogen generators dialed-in to meet the specific requirements of the heat treating industry, companies are recognizing the numerous benefits, including reducing operational expenses, and are making the switch.
