Potassium bromate is also used as a chemical reagent and as an oxidizer to mature flour during milling and to condition dough during baking (US FDA, 1994; IARC, 1999). Reacts violently with aluminium, disulfur dibromide, arsenic, carbon, copper, metal sulfides, phosphorus and sulfur. Potassium Bromate acts as oxidizing agents, by helping to improve the dough by giving it long elasticity, rises the bread and better quality of the final product. Is KBrO3 acid or base? chemical structure of potassium bromate Potassium bromate (KBrO3), is a flour "improver" that strengthens dough and allows for greater oven spring and higher rising in the oven. Chemical Status; Cancer: Currently listed. it's a strong oxidizing agent that is reduced smoothly to bromide. potassium iodide to add to 0.0025 mol of potassium bromate(V) to ensure complete reaction. Sodium and potassium bromate are powerful oxidizers used mainly in permanent wave neutralizing solutions and the dying of textiles using sulfur dyes (Mack, 1988). The impact of the oxidants on egg white characteristics was studied in a model system. It is a potassium and bromate salt and an ionic compound. Abstract. Ask Question Asked 3 years, 7 months ago.
