Gluten belongs to a family of proteins found mainly in wheat, spelt, rye and barley. Among the many gluten-based grains, people mainly consume wheat. Gliadin and glutenin are the two main proteins present in gluten, between which Gliadin causes the most harmful effects on human health.
When you mix wheat with water, proteins present in gluten form a sticky network, which comes with a consistency similar to glue. Here, the glue-type property maintains the elasticity of the dough and allows rising of your bread whenever you bake it. In addition, gluten provides a satisfying and a chewy texture to any of the baked items.
