Nitrogen has many applications in the food industry for food conservation. It is also widely used in the sector of beverages, such as beer, one of the most coveted in the world. Although other gases, such as carbon dioxide (CO2), have generally been used to maintain the organoleptic properties of beer, and are pleasing to people's palates, nitrogen is now being used for the same purpose, since among other things:
- Increases the creaminess of the beer foam
- Increases foam stability
For people who serve beer it may seem that creaminess in the foam depends on the way you get the beer, but the reality is that it depends on the foaming technique, or the mixture of gases used to create the foam. For this, both pure nitrogen or a mixture of 70-75% nitrogen and the rest with carbon dioxide can be used.
