Megazyme® Fructanase Mixture (Ultrapure, recombinant, powder)
20,000 Units
SKU N° 700004217 | Numéro de catalogue E-FRPDPU
Fructanase, Amyloglucosidase (E-AMGDF) and Isoamylase (E-ISAMY) are used in the enzyme hydrolysis step of two validated methods for the determination of polydextrose (a low molar mass dietary fiber) in foods: AOAC method 2000.11 and Chinese GB Standard 5009.245-2016.
Components: exo-Inulinase 20,000 U (on kestose at 40°C), endo-inulinase 1000 U (on fructan at 40°C).
Note: This product has been purified to remove α-galactosidase, β-glucanase and pectinase which interfere with the use of the preparation in the measurement of fructan (AOAC Method 997.08) and in the measurement of Polydextrose (AOAC Method 2000.11).
