E230 is a food additive approved by the European Union (EU) and used as an antifungal synthetic preservative in food products, particularly citrus fruits to prevent the growth of penicillium mould. It is mainly used for agricultural purposes.
The common name for E230 is biphenyl or diphenyl.
E230 is synthesised from benzene. Dipping citrus fruits in a solution of diphenyl allows it to penetrate the skin and preserve the fruit inside.
E230 is banned in Australia and has been known to cause liver, as well as central and peripheral nerve damage in some people subject to frequent close contact to large amounts of E230. It is classified as an irritant. Headaches and skin disorders have also been reported in conjunction with the use of E230.
