Description
Hydration-driven enzymatic conversion of rye starch into fermentable sugars with simultaneous extraction of melanoidins.
Technical
Alpha-amylase from malted grains breaks down rye bread polysaccharides into maltose and dextrins, while Maillard reaction products (particularly 2-acetyl-1-pyrroline and maltol) dissolve into the aqueous phase.
Culinary Significance
Creates the distinctive caramelized flavor base for traditional kvass while providing sugars for subsequent lactic acid and alcoholic fermentation.
