Measuring dissolved gases in packaged beverages
When measuring dissolved gases in packaged beverages, the type of package has a considerable influence on the result. If several gases are present, selective analysis methods are required. This article describes which package properties influence the results and which analysis methods are sufficiently selective and accurate.
Carbon dioxide and oxygen are the most important gases dissolved in beverages, nitrogen is becoming increasingly important. If several gases are present, selective analysis methods are required. It is therefore often not possible to determine the carbon dioxide content of beverages with sufficient accuracy using traditional pressure/temperature methods. It is characterized by its good solubility in beverages. ...
