Air Liquide helps you with methods to remove oxygen from drinks (deoxygenation), which protects them from oxidation. Some drinks contain components that are very susceptible to oxidation, which means that color and taste can change during distribution. It has been proven that as little as 10 ppm of oxygen can cause changes. By sparging an inert gas through the beverage prior to storage and bottling, the residual oxygen in the beverage can be reduced to as little as 1 to 3 ppm, extending the shelf life of the beverage.
Inerting, blanketing and sparging
Air Liquide helps you choose a suitable method to avoid oxidation in your drink. Oxidation occurs when the empty space around a product contains moisture and oxygen, which has a negative effect on the product itself. Inerting, blanketing and sparging are the three most common ways to avoid oxidation by eliminating the oxygen in the air around the product. When replacing oxygen with nitrogen or argon, the void is filled with a dry and inert gas that protects the drink.
Dosing and purging
Air Liquide offers solutions for dosing and purging. Liquid nitrogen dosing is a unique process that helps preserve the quality of the beverage and also extends shelf life. Drops of liquid nitrogen are injected when filling bottles and cans to expel air and reduce the oxygen content of the liquid.
