Gluteenivõrgustik

Gluteenivõrgustik refers to the complex three-dimensional structure formed by gluten proteins when flour is mixed with water and kneaded. This network is essential for the texture and elasticity of baked goods such as bread and pasta. When flour, primarily wheat, barley, or rye, comes into contact with water, two main gluten proteins, glutenin and gliadin, begin to interact. Glutenin proteins form long, elastic strands, while gliadin proteins contribute to the dough's extensibility. Through mechanical action, like kneading, these proteins align and cross-link, creating a viscoelastic network that can trap gases produced during fermentation. This trapping of gases is what allows dough to rise and gives baked products their characteristic airy and chewy texture. The strength and extensibility of the gluteenivõrgustik can vary depending on the type of flour, hydration level, and mixing time. A well-developed network provides structure and prevents baked goods from collapsing. Conversely, a weak or underdeveloped network can lead to a dense or crumbly product. Understanding the formation and properties of the gluteenivõrgustik is fundamental in baking science and technology.
