PRACTICAL WALKTHROUGH · PARAMETERS · COMMON MISTAKES
Bread fermentation in Europe is a controlled biological process where yeast and lactic acid bacteria metabolize sugars to produce CO₂, ethanol, and organic acids, shaping dough structure, flavor, and shelf life.
Origin: European bakers (19th–21st century) — Europe
See full technique reference →Saccharomyces cerevisiae ferments glucose to CO₂ and ethanol, while lactic acid bacteria such as Lactobacillus sanfranciscensis and Lactobacillus plantarum produce lactic and acetic acids that lower dough pH. The combined metabolic activities strengthen gluten networks, create gas cells, and develop complex flavor compounds during bulk and proofing stages.
Primary Reaction
Glucose → CO₂ + ethanol (yeast) + lactic acid + acetic acid (lactic acid bacteria)
