termed a 'cold sterilant'. This is because it is injected into the
product stream immediately prior to the filler, where it then kills
any organisms which may be present in the sealed container.

As it is listed as a preservative in the Food Additives
Regulation (EC) 1333/2008 it must be included in the
ingredients list on the label.
