AN73051: Determination of Bromate in Flour and Bread by IC-MS Be the first to rate this application


Potassium bromate is a food additive used as “flour improver” in the baking industry. Bromate is considered a carcinogenic and nephrotoxic substance. We developed a method for a selective and sensitive determination of bromate in flour that uses IC coupled with MS. A recently introduced high-capacity anion-exchange column was used to separate bromate from matrix anions. Six commercial flour and flour products including homemade bread baked using flour containing potassium bromate, were analyzed. LOD and LOQ of bromate in the prepared solution were 0.10 µg/L and 0.34 µg/L, respectively.
