Because of the alpha-(1,6) bound in amylopectin are not hydrolysed by alpha and beta amylase, another enzyme is required to hydrolyse these bonds and allow complete conversion of starch to low molecular weight is limit dextrinase enzyme. For the applications of this enzyme is to increase degree of fermentability.
The amounts of starch degrading enzymes depend on several factors such as barley, degree of steeping, germination temperature and total germination time
