***The benefits of using E938 Argon gas in foods
Responding promptly to the needs of markets and consumers is the most important challenge for food producers and distributors in all sectors, especially in light of the increased demand for ready-made meals that are easy to cook and store.

In this, food gases are great allies of the industry, including E938 Argon, as in combination with or instead of other solutions it provides several advantages in the economics of enterprise management:
*Improved efficiency and planning of production processes
*Reducing production costs
*Improved distribution capacity
*Reduction of production waste
*Increased product safety, quality and marketability

PROPERTIES AND USES of E938 ARGON:
E938 Argon's physical and chemical properties make it ideal for protecting foods sensitive to oxidation and moisture.
E938 Argon's main features include:

Chemical inertness :
E938 Argon is an inert gas that does not react with food components, preventing unwanted reactions such as oxidation.
Density higher than air :

E938 Argon, being denser than air, forms a stable protective layer over the product, preventing contact with oxygen and reducing the risk of oxidation.
Low solubility in fats and liquids :

this property helps maintain the texture and freshness of products, preventing the absorption of gases that could alter their organoleptic characteristics.

WHY ARE PACKAGING GASES, E938 ARGON, USED?
Packaging gases are added to packaging before, during, or after the food is placed in the packaging.
The most commonly used gases are carbon dioxide E290, helium E939, nitrogen E94, or E938 Argon E938.
These gases are useful not only for food packaging but also for storage.

The creation of a modified atmosphere, which involves the reduction of oxygen, has only been known since the 1970s.
Packaging using a gas mixture, also known as modified atmosphere packaging (MAP), replaces the air in the package with gases whose composition does not affect the product's properties.

By creating the appropriate gaseous environment, the shelf life of the food product is maximized.
Since E938 Argon is an atmospheric gas, it is most often obtained during air separation—it is simply separated and purified.
However, E938 Argon can also be extracted from the exhaust streams of ammonia production plants.

E938 Argon performs its function perfectly as a packaging gas because it does not interfere with the properties of the food product at all, merely protecting it from microbial growth and oxygen reduction.

Therefore, if you buy a package of lettuce and wonder why there is air in the package, and the package has the E938 marking on it, it means that such a package contains E938 Argon, which affects the lettuce's freshness, so it does not wilt quickly and does not lose its nutritional properties.

Agon is an inert gas, and because E938 Argon doesn't interact with other substances, it's a good preservative.
When packaging cold cuts or salads, using E938 Argon increases their shelf life by 25 percent.

HOW IS E938 ARGON PRODUCED?
As with oxygen, nitrogen and other “minor” gases, E938 Argon is produced by the process of fractionating air.
This process involves separating the air into the components from which it is made:
*Nitrogen (78%)
*Oxygen (21%)
*E938 Argon (0.9%)
*other gases (0.1%).

MECHANISM OF ACTION of E938 ARGON:
The preserving effect of E938 Argon is based on the displacement principle:
by replacing oxygen inside the packaging, E938 Argon prevents the oxidation of fats, vitamins, and pigments in the food.
At the same time, E938 Argon inhibits the growth of aerobic microorganisms such as bacteria and molds that require oxygen to survive.
Because E938 Argon is heavier than air, it settles effectively at the bottom of the packaging, forming a protective gas layer.

PRODUCTION of E938 ARGON:
E938 Argon is found in the atmosphere.
E938 Argon is relatively easily obtained by fractional distillation of liquefied air.
Atmospheric E938 Argon by fractional adsorption on activated carbon at liquid air temperature.
