High purity Fructanase Mixture (liquid) for use in research, biochemical enzyme assays and in vitro diagnostic analysis.
For Fructan Determination.
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.
Components: exo-Inulinase (2,000 U/mL on kestose, at 40oC) and endo-Inulinase (100 U/mL on inulin at 40oC).
Note: This product is a mixture of two ultrapure, recombinant enzymes. Suitable for the measurement of fructan (AOAC Method 997.08) and in the measurement of Polydextrose (AOAC Method 2000.11).
