Research Abstract

Maltol are used as a flavor enhancer in breads and cakes. It became mutagenic to bacteria, when the solution was irradiated with UV. Formaldehyde was detected in a crude fraction containing mutagenic photoproduct from UVC-irradiated maltol. However, formaldehyde contributed less than 10% of mutagenicity of the mutagenic fraction.
