Alpha Amylase Enzyme Formula For Brewing, Fermentation

Alpha amylase is a starch-hydrolyzing enzyme preparation supplied as a formulated powder for brewing and fermentation use. It cleaves the internal bonds of amylose and amylopectin, breaking long starch chains into shorter dextrins and fermentable sugars.

Brewers and distillers add it during mashing to improve starch conversion and extract efficiency, particularly with adjuncts such as corn, rice or unmalted grain that carry little diastatic power of their own. It is also used to thin high-viscosity mashes and to reduce residual starch haze. Activity depends on mash temperature and pH, so both should be held within the enzyme's working range.
