Diphenyl (Biphenyl(phenylbenzene). Diphenyl was used as a preservative/fungicide. Diphenyl was authorised in the EU under the number E 230 as a fungicide or preservative for food. The substance was mainly applied externally on citrus fruit peels. Diphenyl is now banned in the EU as a post-harvest treatment agent for citrus fruits.
