Beverage Applications

CO2 is used to carbonate beverages such as soft drinks, sparkling mineral water, beer and certain speciality beverages. During production, the CO2 level needs to be adjusted according to the formulation, product characteristics and sensory requirements.
The appropriate amount of CO2 creates the required effervescence, refreshing mouthfeel and characteristic flavour while maintaining consistent product quality. Controlling the carbonation process also helps ensure that the product meets requirements before filling and packaging.

In beverage production, oxygen can affect product colour, flavour and stability. Nitrogen or argon can be used to replace oxygen in the headspace, storage tanks or certain processing stages to limit oxidation.
This application is particularly suitable for oxygen-sensitive products where flavour, colour and consistent quality need to be maintained during production and storage.

In certain bottling or canning processes, liquid nitrogen can be used to help displace air from the package, reduce residual oxygen and create internal pressure after filling. This helps protect the product and supports package stability during storage and transport.

For certain PET bottles, cans or thin-walled packaging, controlling the internal pressure is important to limit deformation, denting or collapse. Liquid nitrogen can be used in such cases to create internal pressure and increase packaging stability.
