E230

Preservative.

Synthesised from benzene. A white, water-insoluble powder used predominantly against Penicillium fungi growing on citrus fruits. It is used to disinfect containers and in impregnating the wrapping of citrus fruits. Sometimes fruits are dipped in a solution of biphenyl, which slowly penetrates the peel and may be present in the fruit itself. Typically found impregnated into citrus fruit wrappers to prevent post harvest diseases.

It is excreted unaltered by the kidneys. Sensitivity has been reported for people handling large consignments of citrus fruits (ships, trucks).

Used for agricultural purposes (an aromatic fungicide), it is a skin and eye irritant.

Biphenyl is a constituent of the wood preservative creosote.

Not recommended for consumption by children.
