Applications Of Nitrogen In Food And Beverage Industry


Nitrogen is widely used in many industries and fields such as agriculture, food preservation, medicine, energy, chemicals, etc. In this article, we specifically discuss the application of nitrogen in food and beverage preservation.

Nitrogen is extensively used in the food and beverage industry to keep products fresh and of high quality.

Why are nitrogen chosen to preserve food and beverage?

The main cause of food and beverage spoilage is bacteria, which require oxygen to survive and grow. Therefore, by removing oxygen and filling the packaging with nitrogen, the formation of molds or other harmful substances on the products can be prevented. All industries and types of packaging can benefit from nitrogen gas, from cans and bottles to bags and boxes. Here are the main benefits of using nitrogen gas to fill food packaging.

By removing air in the packaging or other preservatives, nitrogen gas helps to restrict oxidation and the growth of bacteria, molds, and other microorganisms, allowing products to be preserved for a longer time and maintain their fresh taste.

Nitrogen is also used for cooling, especially in beer and wine production. In the brewing and winemaking process, nitrogen gas is used to cool the containers quickly and control their temperature.

Nitrogen gas is also used to create foam in coffee, cream, and other beverages with bubbles, making the products more visually appealing and enhancing the customer experience.

Therefore, nitrogen gas is an essential component in the food and beverage industry, helping to enhance preservation, cooling, packaging, and foam creation for products, ensuring quality and freshness for customers.

The process of preserving food and beverages using nitrogen gas

The process of preserving food with nitrogen gas is usually done by injecting nitrogen into the product packaging, removing air and moisture inside to keep the product preserved for longer and maintain a fresh taste. Specifically, the process of preserving food with nitrogen gas is as follows:

  • Prepare the product that needs to be preserved and suitable packaging.
  • Pack the product into the packaging and leave some empty space inside the packaging.
  • Nitrogen gas is pumped into the packaging through a conduit or gas valve.
  • Nitrogen gas will remove most of the air in the packaging, reduce the oxidation of the product, and prevent the growth of bacteria, mold, and other microorganisms.
  • The packaging is then sealed to preserve the product inside.

Preserving food with nitrogen gas allows products to be preserved for longer periods without using preservatives or other technologies. In addition, the product retains its flavor and freshness, bringing trust and satisfaction to consumers about the quality of the product.

Is nitrogen gas used to preserve food toxic?

Nitrogen gas is not toxic to humans, so it does not harm health if used properly and in small amounts.

However, the use of nitrogen gas in food preservation must comply with safety regulations and ensure that the amount of nitrogen gas used does not exceed the prescribed limit.
