When nitrogen is introduced into a package, it drives out oxygen and any moisture present. By modifying the atmosphere inside the package, food packaging with nitrogen preserves quality, slows down spoilage and extends the products' shelf life
How Nitrogen Protects Food
What exactly does this additional barrier of nitrogen do for a food product? It all comes down to reduced exposure to oxygen, which prevents:
Discoloration: Consumers expect a particular color when buying food. Even though oxygen doesn't spoil the food, it can still be discolored, creating a less-appetizing product and experience for the customer. This process is called enzymatic browning and often occurs in fruits and vegetables as the enzymes' natural processes are sped up in the presence of oxygen. If you've ever cut an apple and watched it turn brown when you don't eat it quickly, you've seen enzymatic browning in action. This type of oxidation can also cause the nutritional content of a product to be reduced.
Spoilage: Of course, as food is exposed to the elements, it's going to break down faster. Exposure to oxygen causes lipid oxidation, which brings discoloration and odd flavors, along with a loss of nutrients.
Texture Differences: Oxygen spoilage can also affect the texture of the food, leading to mushy vegetables, stale chips and other effects.
"Off" Flavors: Similarly, as food breaks down upon exposure to oxygen and as bacteria eats away at it, you might notice some odd flavors.
Many of these factors come from a combination of factors, like enzymatic processes, physical damage and microbial growth. That last factor can have various effects and isn't always visible — a perfectly ripe-looking tomato can be filled with undesirable bacteria. Different types of food are susceptible to many types of microorganisms, but keeping oxygen out of the equation is an effective way to prevent their growth and negative effects.
