E223 is a food additive approved by
the European Union (EU) and used as an antimicrobial, antioxidant synthetic
and bleaching agent in food products.
The common name of E223 is sodium metabisulphite.
It is also known as pyrosulphurous acid or disodium
As with other sulphurous
acid salts, the chemical’s oxidising effect has the disadvantage
of reducing the vitamin content of the food containing it.
E223 is a sodium salt of sulphurous acid. Added sulphites (E221 – E228)
should be avoided if an individual is intolerant to natural sulphites.
The chemical is hard to metabolise in those with impaired function of
the kidneys and is known to illicit asthma attacks in asthmatics.
Examples of food/drink products that may include E223:
Vegetables (especially frozen), fruit juice, pickles, frozen shellfish
and dried fruits.
