Carbon dioxide and sparkling water
Carbon dioxide – in the food sector E290 – is used as a propellant for tapping (mainly beer, but there are those who also use it for wine). Furthermore, carbon dioxide is the food gas used in the household gas cylinders, to ‘’gass’’ natural water, making it sparkling.
Nitrogen, beer, wine
Nitrogen is used in the food sector for the inertization and bottling of wine. Going to fill the empty part of a wine bottle with nitrogen prevents the drink from oxidizing when it comes into contract with oxygen. In some cases, even nitrogen is used as a propellant for wine and beer taps.
Argon: a noble gas
Argon gas is a noble gas which, in the food sector, is mainly used for storing wines. In particular, during the bottling phase, it is used to maintain the quality of the wine, also thanks to its being odorless, tasteless, non-corrosive and non-flammable.
Oxygen: the most famous gas
Perhaps the best known and among the most widespread gases on our planet (especially in the Earth’s atmosphere), Oxygen is used in many food sectors (for example as an E948 additive), but also in the therapeutic/hospital sector, as a drug (when speaks of medical oxygen), in hyperbaric chambers and in oxygen therapy.
