11.5.1 - Total (Dissolved and Headspace) Oxygen in Packaged Beer
- Packaging and Packaging Materials
The determination of the total (the dissolved and the headspace) content of oxygen in packaged beer, in bottle, can, keg and cask, by means of detecting oxygen ingress during packaging transfer and filling. Descriptors: headspace volume, net content, correlation between the oxygen content of a liquid phase and of a gas phase at equilibrium, temperature of the sample in degrees K, reading of the oxygen meter in mg/litre or ug/l, conversion of the headspace ratio.
It is necessary to use EBC Methods 9.37, 11.3.2, 11.3.1, 11.27, 11.14 and 11.18
