Nitrogen, designated E941 in the food industry, is a noble gas used as protective packaging for a wide range of food products. As a colorless, odorless and non-toxic gas, nitrogen is ideal for preserving the freshness and extending the shelf life of food by minimizing the influence of oxygen, preventing oxidation and spoilage processes.
Its use in protective packaging technology significantly improves the quality of stored food products while maintaining their natural properties.
Properties of Nitrogen
Nitrogen has very low reactivity, which makes it an excellent choice for creating a protective atmosphere in food packaging. Its ability to displace oxygen from the package reduces the risk of growth of bacteria and other microorganisms, and also slows down oxidation processes.
Applications of Nitrogen
E941 is commonly used in the packaging of food products such as snacks, coffees, teas, dried fruits, nuts and in oxidation-sensitive products. Nitrogen is also used in the beverage industry, including the packaging of beer and wine to prevent oxidation and preserve freshness.
Where to buy Nitrogen?
Nitrogen is available through industrial gas suppliers, offering a variety of gas cylinder capacities. Because of its versatile applications, it is readily available to both large food manufacturers and smaller companies.
Nitrogen and its functions in food
In the food industry, E941 plays a key role in protecting food from spoilage, maintaining its quality, freshness and nutritional value. Using nitrogen as a protective gas is an effective way to extend the shelf life of food products without adding chemical preservatives.
