The method describes how to calculate the total exposure of individuals to radionuclides in drinking water.
Drinking water intended for use as an ingredient in the production of beer (brewing liquor) or other foods
Determination of the total oxygen content (dissolved and in the headspace) in filled containers
The bottled or canned beer is brought to 20 °C and mechanically shaken, thereby achieving equilibrium between the oxygen dissolved in the beer and the oxygen present in the headspace (Henry’s and Dalton’s laws). By directly measuring either the oxygen in the beer or in the headspace, the total oxygen can be calculated through referencing a table of values, which includes the headspace volume as a percentage of the fill volume.
This test method provides a means for evaluating any possible influence originating from the spray-coated lining of a sealed can on the beverage packaged within.
Beverage cans which are used in the brewing and food production industries
The inner lining of the can and the lid should not influence the odor/aroma or flavor of the product in any way. For this reason, the inner lining must conform to the regulations governing foods in the European Union and to those of the respective member states pursuant to their valid constitutions. Furthermore, the provisions drawn up by the BGVV Commission on Plastics in Germany (Bundesinstitut für gesundheitlichen Verbraucherschutz und Veterinärmedizin) must also be taken into consideration.
The safest approach is to perform a comparative taste test with mineral water or beer from the same batch that has been treated in an identical manner in a can (sample) and in a bottle (reference).
Large-format beverage cans (also known as mini kegs or party kegs) which are used in the brewing and food production industries
The inner lining of the mini keg and the lid should not influence the aroma or flavor of the product in any way. For this reason, the inner lining must conform to the regulations governing foods in the European Union and to those of the respective member states pursuant to their valid constitutions. Furthermore, the provisions drawn up by the BGVV Commission on Plastics in Germany (Bundesinstitut für gesundheitlichen Verbraucherschutz und Veterinärmedizin) must also be taken into consideration.
