Carbon dioxide (CO₂) inhibits the growth of most aerobic bacteria and moulds. Generally speaking, the higher the level of CO₂, the longer the achievable shelf-life. However, CO₂ is readily absorbed by fats and water - therefore, most foods will absorb CO₂. Excess levels of CO₂ in MAP can cause flavour tainting, drip loss and pack collapse. It is important, therefore, that a balance is struck between the commercially desirable shelf-life of a product and the degree to which any negative effects can be tolerated. When CO₂ is required to control bacterial and mould growth, a minimum of 20% is recommended.

Where drinking water is extracted from the ground, mineral content isn’t optimal for human consumption or can be unsuitable for entering into copper pipe networks where the water's low minerality can corrode piping. CO₂ in combination with calcite helps to correct water hardness to prevent corrosion build-up leading to network damage.
Adding CO₂ to drinking water increases hardness of the water stream, maintaining an equilibrium between carbonate, bicarbonate and free CO₂ and increasing the water mineralisation and dosage of each reagent.

Carbon dioxide (CO₂) provides a natural user-friendly alternative to mineral acids for the pH control in swimming pools. In water, CO₂ forms a mild carbonic acid that also helps maintain alkanility and reduces total dissolved solids.

When we talk about dry Ice (or dry ice) we refer to carbon dioxide (CO₂) in solid state. We call it that because its temperature is very low (sublimates at -78.5°C) and has the same appearance as ice, but when it evaporates, it leaves no water or any kind of residue. In addition, it also reduces the degree of humidity in the environment.
The Dry Ice is an excellent coolant, ideal to conserve moisture sensitive products and suitable for many applications such as catering, events, food preservation, oenology, refrigerated transport, industrial cleaning and in the pharmaceutical industry for the preservation of vaccinations, biological materials, etc.

Using a gas mixture for lagers, stouts and ciders dispensing provides a creamier longer lasting head and in general improves the appearance of the beer being dispensed. It also reduces fobbing and ensures faster dispensing.
Depending on the drink type, you will need a different gas mixture:
