  • Saccharification and Fermentation products from

    The liquefied mash then goes into the saccharification and fermentation step. Saccharification breaks down shorter glucose chains (dextrins) into fermentable sugars. A glucoamylase enzyme is used to hydrolyze liquified starch to single glucose molecules, where yeast then converts glucose to ethanol and CO2 during fermentation.
