What Is Chlorine?
Chlorine gas has been used historically as a flour bleaching and aging agent — it whitens flour and conditions gluten structure. However, the EU does not permit chlorine as a flour treatment agent, though it is authorized in the USA and Canada. Chlorine reacts with flour components to oxidize pigments and modify protein structure, producing whiter flour with different baking properties. JECFA considers it acceptable for flour treatment with no specific ADI. EFSA has not authorized chlorine as a food additive in the EU. Approved in USA and Canada for flour treatment.
? Did You Know?
In the EU, Chlorine has a "quantum satis" authorization — Latin for "as much as needed." This means there's no specific maximum limit; manufacturers use only what's technologically necessary.
