Mutagenicity of UV-irradiated maltol in Salmonella typhimurium.

We investigated the photomutagenicity of maltol (3-hydroxy-2-methyl-4H-pyran-4-one) in bacterial cells. Maltol has a caramel-butterscotch odour and is used as a food additive to impart flavour to bread and cakes. Unirradiated maltol was not mutagenic up to 5 mg/plate in the Ames test. When maltol was irradiated with either UVA (a black light, 320-400 nm, 230 microW/cm(2)) for 5-30 min or UVC (a...
