Argon (E938) - what is it?

Argon, designated E938 in the food industry, is a noble gas used as a protective packaging to extend the shelf life of food products. As a colorless, odorless and non-toxic element, argon is a safe alternative to traditional protective gases such as nitrogen. Using argon in the food industry takes advantage of its property of minimal chemical reactivity, which helps protect food from oxidation and other degradation processes.

Properties of Argon

Argon has exceptional chemical stability, which makes it effective in protecting food from oxidation processes. Its density is higher than that of air, allowing it to better insulate food products from the external atmosphere and increase its effectiveness as a protective packaging.

Application of Argon

E938 is used in various segments of the food industry, including packaging of meats, fish, seafood, as well as in bakery products and cheese. The use of argon as a protective packaging allows the freshness of products to be prolonged without the addition of preservatives.

Where to buy Argon?

Argon is available through industrial and specialty gas suppliers, offering different cylinder capacities depending on your needs. It can be purchased both in stationary stores and online.

Argon and its functions in food

As a food additive, E938 plays a key role in preserving the quality and extending the shelf life of food products. Using argon as a protective gas allows food to maintain its natural flavor and nutritional properties, minimizing the need for additional preservatives.
