Description
Dosa batter undergoes lactic acid and yeast fermentation, producing acids and CO₂ that tenderize the batter and create a light, airy texture with a characteristic tang.
Technical
During fermentation, lactic acid bacteria such as Lactobacillus plantarum convert soluble sugars to lactic acid, lowering the pH to 4.5–5.0. Yeast (Saccharomyces cerevisiae) metabolizes sugars to CO₂ and ethanol, while microbial amylases and proteases hydrolyze starches and proteins, enhancing digestibility and contributing to the batter’s viscosity and flavor.
