Bread flour is high in gluten protein, with 12.5-14% protein compared to 10-12% protein in all-purpose flour. The increased protein binds to the flour to entrap carbon dioxide released by the yeast fermentation process, resulting in a stronger rise. Bread flour may be made with a hard spring wheat.
All purpose flour can be used in more recipes than plain flour. The gluten level in all purpose flour is also higher than the gluten level in plain flour. Both the types of flour differ from each other in terms of hardness. It is said that all purpose flour is a little bit harder than plain flour. It is also coarser when compared to plain flour. On the other hand, plain flour is softer and hence, is preferably used in the making of different types of cakes. These are the important differences between all purpose flour and plain flour.
