What is vital wheat gluten
Wheat gluten are functional proteins obtained by hydrating wheat flour, which activates the gluten. Afterwards, starch and other components are removed, leaving a virtually pure gluten concentrate. The end product is a fine powder that resembles flour in appearance, but consists of 80-85% protein. Wheat gluten is widely used in industrial processes as a binder and structure improver. They contribute to improved texture, elasticity, and leavening power of dough, and also serve as an important ingredient in meat substitutes such as seitan.
Application in bakeries and meat substitutes
Thanks to its functional properties, wheat gluten is widely used in various sectors, including industrial bakeries for products such as bread, where it provides structure and volume. Additionally, it is used in the production of vegetarian and vegan meat alternatives like seitan, and in processed foods where extra binding, structure, or volume is desired. The use of wheat gluten ensures improved dough elasticity, a lighter final structure, and an increased protein concentration in the end product.
Technical properties and benefits of wheat gluten.
Wheat gluten primarily consists of the proteins gliadin and glutenin, with gliadin providing viscosity and glutenin contributing to the elasticity of dough. The amino acid profile of wheat gluten is dominated by glutamine and proline, supplemented by significant amounts of valine, leucine, isoleucine, and phenylalanine. The relatively low lysine content makes wheat gluten less suitable as the sole protein source in balanced diets, but they are excellent for technological applications such as dough strengthening and structure formation.

Frequently asked questions
Wheat gluten is particularly rich in functional proteins such as gliadin and glutenin, which provide unique baking properties. Compared to grains like rice, corn, or oats, wheat gluten contains significantly more of these specific proteins, making it particularly suitable for applications where elasticity and structure are important.
Gluten themselves do not directly affect blood sugar levels, as they consist almost exclusively of proteins. However, it is important to realize that many gluten-containing products, such as bread, pasta, and pastries, are often rich in carbohydrates. Therefore, for people with diabetes, it is wise to pay attention to the amount of carbohydrates in these products, as these do affect blood sugar levels.
Wheat gluten contains high levels of glutamine and proline, with significant amounts of valine, leucine, isoleucine, and phenylalanine. Lysine is relatively limited.
