How does the amount of gluten in flour affect a baked product?

In baking, the amount and type of gluten in flour are primary factors in determining the final structure and texture of a product. When flour is mixed with water, its proteins form an elastic network that traps carbon dioxide, allowing the dough to expand and rise.123

The strength of this network depends on the flour's protein content:

• High-protein (Hard Wheat) Flour: Containing approximately 12–15 percent protein, these flours create a strong, elastic structure. They are ideal for products that require significant expansion and a firm, spongy texture, such as bread, hard rolls, and yeast-raised sweet rolls.23
• Low-protein (Soft Wheat) Flour: Containing approximately 8–12 percent protein, these flours produce a more delicate structure. They are best suited for items that do not require high elasticity or great expansion, such as cakes, pie crusts, cookies, and crackers.23

Ultimately, the gluten content dictates whether a dough is soft and extensible or tough and elastic, directly influencing the suitability of the flour for specific recipes.1
