Flour treatment agents (also called improving agents) are food additives added to flour in order to improve its properties. ...

When it reacts with flour, it behaves as a hydrogen acceptor, and is quickly and completely converted to biurea, which is stable even during baking. The reaction occurs only during wetting of the dough. Acceptable doses for flour treatment range between 0-45 ppm. Parts per million (ppm) is a measure of concentration that is used where low levels of concentration are significant. ...

It is also used in the production of foamed plastics and the manufacture of gaskets. Use of azodicarbonamide as a food additive is banned in Australia.

In the UK, the Health and Safety Executive has identified azodicarbonamide as a respiratory sensitiser (a possible cause of asthma) and determined that products should be labeled with "May cause sensitisation by inhalation." [1] The Health and Safety Executive (HSE), reporting to the Health and Safety Commission, is the British government body responsible for the regulation of risks to health and safety in the UK. It was created as a result of the Health and Safety at Work, etc, Act 1974, and has since...
