What You Need to Know
Yeast cells metabolize sugars to produce CO₂ and ethanol, while gluten proteins form a viscoelastic network that is strengthened by oxidizing agents and weakened by acid or overmixing. Temperature shifts alter enzyme kinetics and membrane fluidity, affecting fermentation rate and gluten relaxation. Moisture loss triggers starch retrogradation, leading to staling.
The Science
Primary Reaction
Yeast fermentation (glucose → CO₂ + ethanol + acids)
