Fructanase Mixture (purified-liquid)
For Fructan Determination (Liquid).
Components: exo-inulinase 2000 U/ml (on kestose, at 40°C), endo-inulinase 200 U/ml (on fructan at 40°C), α-galactosidase < 0.1 U/ml (on p-nitrophenyl α-galactoside at 40°C), ß-Glucanase < 0.12 U/ml (on ß-glucan at 40°C) and pectinase < 0.40 U/ml (on pectin at 40°C).
Note: This product has been purified to remove α-galactosidase, ß-glucanase and pectinase which interfere with the use of the preparation in the measurement of fructan, or in the solubilisation of "insoluble" fructan in the AOAC Total Dietary Fibre method. In this product, the contamination of exo-inulinase by α-galactosidase, ß-glucanase and pectinase is 0.005%, 0.006% and 0.02%, respectively. In Fructozyme (NOVO), the contamination by α-galactosidase, ß-glucanase and pectinase is 14.2%, 0.2% and 2% respectively.
Stable at 4°C for > 4 years.
