Food & Beverage

Without the aid of atmospheric gases, beverages would be flat, transporting food would be extremely difficult, shelf life would be minimal, and food producers and distributors would have expensive disposal costs. Carbon dioxide and nitrogen play significant roles in food preservation and transportation. Both gases, sometimes used in a mixture, prevent oxygen exposure (which causes unhealthy compounds, unpleasant tastes, and odors) by displacing oxygen in food packaging. Nitrogen improves freezing and refrigeration techniques, and dry ice (frozen CO2) keeps food cold and prevents insect infestation in grains and farm products. Argon is another commonly used gas, as it’s inert and displaces oxygen.

Carbon Dioxide

Perhaps one of carbon dioxide’s best-known uses is as a carbonation method for soft drinks, seltzer water, and beer. Carbonation is not its only purpose, as it also maintains the fresh taste and color throughout production, transfer, storage, and bottling. Beverage companies rely on it to create bubbles, but also to move products between tanks or kegs and cans. Carbon dioxide prevents unwanted oxidation and premature fermentation at breweries and wineries.

Food distributors use dry ice for transportation, as it turns from solid to gas, without liquifying. This sublimination prevents water and residue from accumulating. These dry ice blocks are sanitary, food-grade and FDA approved. Commercial kitchens regularly use dry ice to refrigerate, flash freeze, and store dry goods.


Modified Atmospheric Packaging (MAP), also known as reduced oxygen packaging, is a blend of carbon dioxide, oxygen and nitrogen that is used to preserve fresh produce, for sparging and brewing applications, for blanketing and purging after packaging, and protection against oxidation.

Moisture inside of packaged food invites unwanted bacteria, mold, and mildew, which is why nitrogen is used to displace oxygen and lock out moisture. More nitrogen is necessary for fresh foods like fruits and vegetables, seafood, meat, and meat products. Dried goods, such as honey and rice, require less nitrogen for packaging.

Nitrogen is also used as a carbonator in specialty beverages, as it produces a different type of carbonation than carbon dioxide. Carbon dioxide is 50 times more soluble in water than nitrogen, creating larger bubbles for extra fizziness. Nitrogen produces less aggressive bubbles for a finer taste. It’s used for nitro brew coffee, kombucha and teas, and some craft beers.


Argon is used in the beverage industry to displace oxygen in spaces as small as a bottle and as large as a barrel. That little burst of rising steam when a cork is popped off a bottle of wine is created courtesy of argon. Any area of a wine bottle or barrel that is not filled with liquid is occupied by some form of gas to lock in freshness during storage. A drop of the inert gas is placed in the headspace before the cork seals the bottle, displacing oxygen and maintaining the wine’s freshness.

Carbon Dioxide

Carbon dioxide (CO₂) is a colorless, odorless gas that naturally occurs in the earth’s atmosphere. It is a dense inert gas that, when combined with argon, is used as a shielding gas in the welding process. Uses for carbon dioxide also include controlling pH levels in paper manufacturing and wastewater treatment and increasing yields in cultivation through the acceleration of natural cycles of photosynthesis.

Greenhouse gas emissions are an environmental concern. Carbon removal initiatives, such as direct air capture, extract carbon dioxide from the air and funnel it to be stored or reused by various industries. Green dry cleaning, with carbon dioxide, is environmentally friendly and replaces toxic cleaning solvents and chemicals like perchloroethylene and chlorine-based mixtures.

In its solid form, carbon dioxide is manufactured into small pellets for dry ice blasting, miraculously blowing away soot, smoke, paint, and excess buildup from coffee roasting machines and commercial kitchen appliances. Dry ice is made when cryogenic carbon dioxide is injected into a holding tank where it can be frozen to its desired temperature of -109 degrees Fahrenheit. Cleaning with carbon dioxide gas applications – both liquid and solid – can, realistically, be an environmentally friendly alternative to cleaning applications that use harsh chemicals that contaminate natural bodies of water through wastewater runoff.

Carbon Dioxide plays a significant role in food preservation and transport. Food distributors use dry ice for transportation, as it turns from solid to gas, without liquifying. This sublimination prevents water and residue from accumulating. These blocks are sanitary, food-grade and FDA approved. Beverage companies rely on it to create bubbles, but also to move product between tanks or to kegs and cans. Carbon Dioxide maintains beverage freshness, taste and color and prevents unwanted oxidation and premature fermentation at breweries and wineries.

Carbon dioxide supplies through RMA are offered in a variety of sizes for a variety of systems.

More About Carbon Dioxide



RMA provides helium (He) for a variety of uses in whatever purity needed. We provide high-pressure gas cylinder and liquid cylinder containers large enough to cool a particle collider or an MRI magnet, and small enough to use for balloons at your next party.

The inert gas can chill temperatures to near absolute zero. Various usages include: pressurizing and leak detection; balloon inflation; fiber optics; and glass production. Helium, however, is more than balloons, but operates within medical, technology, manufacturing, and aerospace industries. Helium is often mixed with other gases, like oxygen, in treatments for respiratory ailments like asthma and emphysema, and breathing cylinders for deep sea dives.

Where is helium found and how is it harvested? Helium is a component of natural gas production and is found within subterranean reserves in places rich in oil like Wyoming, Algeria, Qatar, and Russia. As a non-renewable resource, the helium market frequently undergoes global shortages that disrupt its essential industry applications. Partnering with a helium supplier like RMA can ensure that you have the supplies of helium gas that you need when you need it. Our dedication to flawless dependability prioritizes our partners when shortages arise.

Mixed Gases

Mixed gases are a wide and diverse group of products developed for use in specific industries for customized applications. A gas mixture is defined in a molar gas fraction, by percentage, parts per thousand or parts per million. Though gas mixtures are used in many industries, these are common applications in the medical, food and beverage, and welding industries.

More About Mixed Gases

Nitrogen (N), a colorless, odorless, tasteless gas, is the most common element in our atmosphere at 78%. It’s a component of all living matter, including water, soil, plants, and the human body. It accounts for about 3% of human body weight. Nitrogen has many useful applications in both its gas and liquid forms. One fun fact about nitrogen is that it’s responsible for the Aurora Borealis or Northern Lights’ purple color! When solar wind stimulates nitrogen atoms, the result is the purple and blue-colored lights emitted when the atoms decay.

Nitrogen is unique in that it can be used to prevent fires, but is also used to make explosives. In its natural state, Nitrogen is inert. However, if isolated or harnessed (as in the case of making explosives), it can release a large amount of energy. On the other hand, Nitrogen fights potential fire hazards by eliminating one point in the fire triangle. As a purging gas, its inert nature is denser than oxygen. By removing oxygen, with only heat and fuel remaining, nitrogen eliminates fire’s ability to ignite and thrive.
