A21D TREATMENT OF FLOUR OR DOUGH FOR BAKING, e.g. BY ADDITION OF MATERIALS; BAKING; BAKERY PRODUCTS (preservation of flour or dough before baking A23B40/00; preservation of bakery products A23B45/00)
Introduced: September 1968
Description
A21D covers the chemical and physical treatment of flour and dough before and during baking, including the addition of ingredients, additives, and processing aids that modify dough properties or improve final product quality. This subclass encompasses baking processes, heat treatment of doughs, and the manufacture of finished bakery products such as bread, cakes, pastries, and related items. It includes technologies for dough conditioning, fermentation control, and incorporation of functional ingredients, but excludes the design of baking equipment itself (covered in A21B) and flour milling operations (covered in A21D's parent class A21).
