But what exactly happens to baked products that do not contain gluten? In this article, we will delve into the world of gluten-free baking and explore the challenges, opportunities, and innovations that come with it.
Understanding Gluten and Its Role in Baking
Gluten is a complex protein that plays a crucial role in the structure and texture of baked goods. It is responsible for the elastic and chewy properties of bread, the tender crumb of cakes, and the flaky layers of pastries. Gluten is composed of two main proteins: gliadin and glutenin. Gliadin provides the elasticity and extensibility of dough, while glutenin gives it strength and structure. When gluten is present in dough, it forms a network of strands that traps air bubbles, creating a light and airy texture.
