E 223Preservatives

Sodium metabisulphite

Characteristics

Additive NameSodium metabisulphite
E No.E 223
TypeIndividual Substance
In plain language

A synthetic preservative and antioxidant used to prevent browning and microbial growth in food and drinks. Found mainly in wines, dried fruits, and some seafood products. It releases sulphur dioxide, which is the active preserving agent. People with asthma or sulphite sensitivity can experience reactions — breathing difficulties, skin rashes, or digestive upset. EFSA has set an acceptable daily intake, and its very limited authorisation in only one food category reflects a cautious regulatory approach.
