Megazyme® Fructanase Mixture (powder)
20,000 Units
SKU N° 700004216 | Numéro de catalogue E-FRMXPD
AOAC OMA
High purity Fructanase Mixture (powder) for use in research, biochemical enzyme assays and analytical testing applications.
Components: exo-Inulinase 20,000 U (on kestose at 40°C), endo-inulinase 1000 U (on fructan at 40°C).
Fructanase, along with Amyloglucosidase (E-AMGDF) and Isoamylase (E-ISAMY), can also be utilised in the enzyme hydrolysis step for determining polydextrose a low molecular weight dietary fiber in food samples.
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 and Polydextrose.
