The Keys to Generating Food Grade Nitrogen: Keeping Your Food Fresh and Flavourful

4 min read

Nitrogen, though often overlooked, plays a crucial role in our everyday lives. Beyond its presence in the air we breathe, it’s also an essential ingredient in keeping our food fresh, delicious, and safe.

In the food and beverage industry, food-grade nitrogen reigns supreme, ensuring the quality and longevity of our favourite snacks, drinks, and everything in between. But how do we generate this culinary hero? What are the keys to unlocking a steady supply of pure, food-safe nitrogen? Buckle up, food enthusiasts and science sleuths, as we delve into the fascinating world of nitrogen generation!

What is Food Grade Nitrogen?

Before diving into the generation process, let’s establish the champion we’re dealing with. Food-grade nitrogen isn’t just any nitrogen you pull from the atmosphere. It’s a meticulously purified gas that meets stringent safety standards set by food regulatory agencies.

This means it’s free from harmful contaminants like moisture, oil, and microorganisms, ensuring the purity and integrity of the food it comes in contact with.

There are two primary ways to obtain food-grade nitrogen:

  • Cylinders: These pressurized tanks come pre-filled with nitrogen and offer a convenient, portable solution. However, they can be expensive, require frequent replacements, and pose logistical challenges.
  • Generators: These on-site systems extract nitrogen directly from compressed air. They offer a cost-effective, continuous supply of nitrogen, making them ideal for large-scale food production facilities.

Unlocking the Secrets of Nitrogen Generation:

Generating food-grade nitrogen is a multi-step process that involves separating it from the other gases present in the air. Here’s a simplified breakdown:

  • Air intake: Compressed air is the raw material for nitrogen generation.
  • Pre-filtration: Impurities like dust and moisture are removed to protect the equipment and ensure the purity of the final product.
  • Separation: This is where the magic happens! Different technologies are employed to separate nitrogen from other air components, such as:
  • Pressure Swing Adsorption (PSA): This common method uses carbon molecular sieves to selectively adsorb oxygen and other gases, leaving behind pure nitrogen.
  • Membrane separation: Semipermeable membranes allow nitrogen molecules to pass through while blocking other gases.
  • Post-filtration: The newly extracted nitrogen is further filtered to remove any remaining trace impurities.
  • Quality control: Continuous monitoring and analysis ensures nitrogen meets all food grade purity standards.


Benefits of On-Site Generation:

Choosing an on-site nitrogen generator offers several advantages over relying on cylinders:

  • Cost-effectiveness: Generators eliminate the ongoing expense of purchasing and replacing cylinders, leading to significant long-term savings.
  • Convenience: A steady, on-demand supply of nitrogen means no more worrying about running out or waiting for deliveries.
  • Environmental friendliness: On-site generation reduces the carbon footprint associated with transporting and disposing of cylinders.
  • Greater control: You have complete control over the purity and flow rate of your nitrogen supply.
