E174 is a natural metal food additive approved by the European Union (EU). It is used as a colouring agent in food and drink products.
The common name for E174 is silver, i.e. the chemical element silver.
E174 is silver / grey colouring for food products. This metal is also used in photography, batteries, and for the more obvious uses in jewellery and other silverware such as cutlery. E174 can be obtained by crushed silver bearing ore.
Frequent and prolonged exposure to the dust form of silver may cause argyria, which is permanent staining of the eyes (argyrosis) and skin - especially of the nose and throat, as well as causing eye damage.
Use of silver as a food colouring is banned in Australia.
