What You Need to Know
During proofing, Saccharomyces cerevisiae metabolizes sucrose and maltose released from tapioca starch hydrolysis to produce CO₂ and ethanol, while simultaneously generating organic acids that lower the dough pH. The resulting CO₂ expands gas cells, creating a porous crumb, and the acids modulate gluten‑free matrix stability and impart characteristic tangy notes.
The Science
Primary Reaction
