What You Need to Know
During fermentation, endogenous amylases hydrolyze millet starch into fermentable sugars, which are then converted by yeasts into ethanol and CO₂. Simultaneously, lactic acid bacteria metabolize sugars to lactic acid, lowering pH and inhibiting spoilage organisms. The process also releases free amino acids, reducing phytic acid and tannins, thereby improving protein digestibility.
The Science
Primary Reaction
Starch → sugars → ethanol + CO₂ + lactic acid
