Nitrogen gas is applied in many different industries and fields such as: Agriculture, food preservation, medicine, energy, chemistry… In this article, we specifically talk about the application of nitrogen gas in the food preservation industry. products and beverages.
Nitrogen gas is widely used in the food and beverage industry to keep products fresh and of high quality.
Why choose nitrogen gas for food and beverage preservation?
Bacteria are the main cause of food and drinks spoiling quickly and having a short shelf life, and to survive they need one thing: Oxygen. So, by removing oxygen and filling the packaging with nitrogen, mold or other harmful substances are prevented from forming on the product. Industries and all types of packaging can benefit from nitrogen gas. From cans and bottles to bags and boxes, here are the key benefits of filling food packaging with nitrogen gas.
Therefore, nitrogen gas is often used to preserve food and beverages by removing air from packaging or other preservatives. When air is removed, oxidation and the growth of bacteria, mold, and other microorganisms are limited, helping products to be preserved longer and maintain fresh flavor.
Another use of nitrogen gas is for cooling, especially in the production of beer and wine. During beer and wine production, nitrogen gas is used to rapidly cool and control the temperature of the tanks.
In addition, nitrogen gas is also used to create foam in coffee, ice cream and other frothy drinks, giving the product an attractive appearance and enhancing the customer experience.
Therefore, nitrogen gas is an important ingredient in the food and beverage industry, helping to enhance preservation, cooling, packaging and foaming of products, ensuring product quality and freshness. for customers.
Process of preserving food and beverages with nitrogen gas
The process of preserving food with nitrogen gas is often done by inserting nitrogen gas into the product’s packaging, removing air and moisture inside to keep the product preserved longer and maintain flavor. fresh. Specifically, the process of preserving food with nitrogen gas is as follows:
• Prepare products that need to be stored and packaged appropriately.
• The product is packed into a package and leaves space inside the package.
• Nitrogen gas is injected into the packaging through a hose or air valve.
• Nitrogen gas will remove most of the air in the packaging, reducing oxidation of the product and preventing the growth of bacteria, mold and other microorganisms.
• The packaging is then sealed, so that the product inside is preserved.
Preserving food with nitrogen gas allows products to be preserved for longer periods of time without using preservatives or other technology. In addition, the product also retains its flavor and freshness, giving consumers confidence and satisfaction with product quality.
