title: [The mutagenicity of caramel colors].
abstract: In the present study commercially available caustic and ammoniated caramel colours were tested for their mutagenic potential using the Ames assay. The test was performed using the standard test strains Salmonella typhimurium TA 1535, TA 1537, TA 98 and TA 100 with and without a metabolic activation system (S9-mix). Furthermore, a special preincubation procedure without metabolic activation system was applied. None of the tested caramel colours showed any mutagenic effect in the Ames test.
