Question

What is the primary protein found in wheat responsible for its dough-forming properties?

• A. Casein
• B. Albumin
• C. Gluten
• D. Keratin

Hint:

Gluten formation is essential in baking because it traps gases produced during fermentation, helping bread rise and develop structure.

Answer 1

The Correct Option is C

Concept: Wheat contains storage proteins that are responsible for the elasticity and structure of dough. The most important of these is gluten, which is a composite of two proteins:

• Gliadin – provides extensibility (stretching ability)
• Glutenin – provides elasticity (strength and structure)

When water is added to wheat flour and kneaded, these proteins interact to form a network called gluten, giving dough its characteristic texture.
Step 1: Identify the protein responsible for dough formation.
Among the given options:

• Casein – found in milk
• Albumin – found in eggs
• Gluten – found in wheat
• Keratin – found in hair and nails

Step 2: Select the correct protein.
Gluten is responsible for the viscoelastic nature of dough, enabling it to rise and maintain shape.
