Fungal alpha amylase is an enzyme that catalyses the hydrolysis of starch into sugars. The α-amylases acting at random locations along the starch chain, it breaks down long chain saccharides during the milling process into dextrins. The α-amylases yields either maltotriose and maltose from amylose, or maltose, glucose and dextrin (limitied) from amylopectin.
Yeast contains a maltase enzyme which cleaves the maltose into glucose molecules which provides an energy source for the yeast to ferment.
