Understanding What Impacts 100% of Baked Product Size & Shape

The size and shape of baked products are fundamental attributes that directly influence consumer perception. From the height of a pan bread to the roundness of a hamburger bun or the elegant layering of a croissant, these visual cues reflect both flour quality and process control.

This document explores the flour components that most strongly define product size and shape. Proteins create the gluten network that balances strength and extensibility, allowing dough to expand properly while maintaining structure. Damaged starch supports gas retention, but excessive levels can weaken dough and lead to irregular forms. Enzymatic activity ensures consistent fermentation, while starch viscosity drives volume through gelatinization during baking. Minerals (ash content) help define precision of shape, and lipids enhance dough handling and promote symmetry.

By linking these scientific factors to measurable flour properties, bakers and millers can better anticipate dough behavior, optimize baking performance, and achieve consistent products with the desired size and shape.
