What You Need to Know
During fermentation, starches in millet are hydrolyzed by amylases into sugars, which are then converted by lactic acid bacteria into lactic acid and by yeasts into ethanol and CO₂. The acidification lowers pH, inhibiting spoilage microbes and improving digestibility, while volatile compounds contribute to aroma and flavor.
The Science
Primary Reaction
Starch → sugars → lactic acid + ethanol + CO₂
