The fast-reacting ADA can be replaced by mixtures of calcium peroxide and ascorbic acid. Ascorbic acid can only be omitted (in the absence of any other oxidizing agent) if limitations to baking performance are tolerated. Oxidizing enzymes such as glucose oxidase are not very effective in the centre of the dough unless the mixing process is performed at elevated air pressure or with the introduction of oxygen into the dough.

The dark colour of wholemeal flour is not only due to carotenoids with which benzoyl peroxide reacts. b. Because of the high concentration of pigments the BPO is exhausted before it achieves a bri…
