Fructanase, Amyloglucosidase (E-AMGDF) and Isoamylase (E-ISAMY) are used in the enzyme hydrolysis step of the AOAC method 2001.11 for the determination of polydextrose (a low molar mass dietary fiber) in foods.
EC 3.2.1.7
CAZy Family: GH32 
EC 3.2.1.80
CAZy Family: GH32 
Components: exo-inulinase 20,000 U (on kestose, at 40oC), endo-inulinase 1000 U (on fructan at 40oC), α-galactosidase 0.70 U (on p-nitrophenyl α-galactoside at 40oC), β-Glucanase 1.25 U (on β-glucan at 40oC) and pectinase 5.5 U (on pectin at 40oC). 
Note: This product has been purified to remove most of the contamination with α-galactosidase, β-glucanase and pectinase which can interfere with the use of the preparation in the measurement of fructan, or in the solubilisation of "insoluble" fructan in the AOAC Total Dietary Fiber method. In this product, the contamination of exo-inulinase by α-galactosidase, β-glucanase and pectinase is 0.003%, 0.005% and 0.022%, respectively. In Fructozyme (NOVO), the contamination by α-galactosidase, β-glucanase and pectinase is 15.2%, 0.3% and 2% respectively.
Stable at -20oC for > 4 years.
