What You Need to Know
Saccharomyces cerevisiae metabolizes glucose and fructose via glycolysis and alcoholic fermentation, producing CO₂ and ethanol. The CO₂ gas forms bubbles that leaven the dough, while ethanol contributes to the bread’s aroma and partially evaporates during baking. Concurrent acid production lowers pH, activating enzymes that further soften gluten and enhance flavor complexity.
