Question

How does yeast fermentation affect bread dough during the baking process?

विकल्प

• It develops harmful bacteria

• It produces CO₂ that causes the dough to rise and become porous

• It adds water to the dough

• It decreases the nutritional value

Answer 1

Yeast fermentation produces carbon dioxide (CO₂) gas that becomes trapped in the bread dough, causing it to rise and become porous. Baking then sets this expanded dough into bread, resulting in a light, airy texture with proper bread structure.
