What You Need to Know
During fermentation, lactic acid bacteria convert sugars in Parkia biglobosa into lactic acid, lowering the pH and reducing bitterness. The simmering step hydrolyzes tannins and releases polysaccharides, creating a smooth mouthfeel while preserving volatile acids that contribute to the soup’s aroma.
