Enzyme Information


I.U.B. 9000-90-2


Starch-breaking enzymes, such as Amylase work together to break both α-1,4 and α-1,6 bonds to more fully digest the various types of dietary starches.

The food grade amylase enzyme used in National Enzyme Company products is obtained by controlled fermentation of Aspergillus oryzae. This enzyme will randomly hydrolyze the interior alpha‐1,4‐ glucosidic bonds of starch. This enzyme has a dextrinizing action that reduces the viscosity of gelatinous starch, amylose and amylopectin solutions yielding soluble dextrins. Its saccharifying action liberates glucose and maltose.


One FCC alpha‐amylase Dextrinizing Unit (DU) is defined as the quantity of alpha‐amylase that will dextrinize soluble starch in the presence of an excess of beta‐amylase at the rate of one gram per hour at 30°C. The assay is based on the time required for an alpha‐ amylase to hydrolyze a limit dextrin substrate to a defined blue value. The degree of hydrolysis is determined by comparing the blue value of the hydrolyzed limit dextrin substrate with that of a color standard.


This enzyme is used for the hydrolysis of starch in various industries, including the brewing and baking industries. In the health and wellness industry, amylase is used as a digestive aid. Other applications include use in detergents, fruit juice processing, paper mills and waste treatment.
