Enzyme Information


I.U.B. 9032-08-0


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

The glucoamylase (Amyloglucosidase) enzyme used by National Enzyme Company is a food grade enzyme complex obtained by controlled fermentation of Aspergillus niger. The enzyme hydrolyzes terminal 1,4-linked alpha-D-glucose residues successively from non-reducing ends of amylose chains to release free glucose. This fermentation also possesses the ability to hydrolyze alpha-1, 6-glu- cosidic linkages in isomaltose and dextrins.


FCC Amyloglucosidase Units (AGU) are defined as the amount of glucoamylase that will liberate 0.1 μmol/min of p-nitrophenol from p-nitrophenol-alpha-glucopyromoside at pH 4.3 and 50°C.


This enzyme is used in the food industry to produce glucose from starch. Amyloglucosidase has found applications in alcohol pro- duction, baking, dental hygiene, fruit juicing, waste treatment and as a digestive aid. The use of this enzyme to improve livestock nutrition and growth has been the subject of much research.
