Alpha Amylase

Alpha Amylase is one of the two diastatic enzymes in malt that attacks the 1-4 carbon links of straight-chain starches. This enzyme is produced by malting barley. It is known as the liquefying enzyme.

This enzyme aids the brewer by converting straight-chain amylose into smaller, more fermentable sugars such as maltose, maltriose, maltotetraose, as well as non-fermentable dextrins and alpha glucans.
