There is disclosed a method for making pullman type breads, which comprises incorporating potassium bromate as an aqueous solution in the step of forming a bread dough in combination with ascorbic acid alone, or alternatively, in combination with ferrous sulfate and ascorbic acid, such that the solubility of the incorporated potassium bromate is increased in the bread dough to facilitate chemical decomposition of bromate, wherein the resulting baked breads of the pullman type are free from residual bromate. The pullman type breads thus prepared are advantageous in that potassium bromate, an excellent bread improver, can be used to provide baked breads free from residual bromate without affecting the flavor and taste of the breads.
