Description
Bread dough rising is a biological fermentation process where yeast metabolizes sugars to produce CO₂ and ethanol, expanding gluten networks and creating a porous crumb structure.
Technical
During fermentation, glucose is converted via alcoholic fermentation to ethanol and carbon dioxide, while water is produced. The CO₂ forms bubbles that are trapped by the viscoelastic gluten matrix, causing dough expansion. Temperature and time control the rate of yeast activity and gluten development, balancing gas production with structural integrity.
