In biscuit making, use of chlorinated flour reduces the spread of the dough, and provides a "tighter" surface. The changes of functional properties of the flour proteins are likely to be caused by their oxidation. In countries where bleached flour is prohibited, microwaving plain flour produces similar chemical changes to the bleaching process ...
A dough conditioner, flour treatment agent, improving agent or bread improver is any ingredient or chemical added to bread dough to strengthen its texture or otherwise improve it in some way. Dough conditioners may include enzymes , yeast nutrients, mineral salts, oxidants and reductants , bleaching agents and emulsifiers . [ 1 ]
As a food additive, azodicarbonamide is used as a flour bleaching agent and a dough conditioner. [8] It reacts with moist flour as an oxidizing agent. [9] The main reaction product is biurea, which is stable during baking. [9] Secondary reaction products include semicarbazide and ethyl carbamate. [8] It is known by the E number E927. Many ...
"Bleached flour" is "refined" flour with a chemical whitening (bleaching) agent added. "Refined" flour has had the germ and bran, containing much of the nutritional fibre and vitamins, [citation needed] removed and is often referred to as "white flour". Bleached flour is artificially aged using a "bleaching" agent, a "maturing" agent, or both.
The flour used in white breads is often bleached further—by the use of flour bleaching agents such as potassium bromate, azodicarbonamide, or chlorine dioxide gas to remove any slight natural yellow shade and make its baking properties more predictable.
Azodicarbonamide – flour bleaching agent. Also used in the production of foamed plastics and the manufacture of gaskets. Banned as a food additive in Australia and Europe. Azorubine – color (red) (FDA: Ext D&C Red #10)

It is mainly used as an oxidant to enhance the extraction of precious metals from their ores. In its second main application, it is used as a food additive under the E number E930 it is used as flour bleaching agent and improving agent. [3] In agriculture it is used in the presowing treatments of rice seed.
