果糖酶混合物 (纯粉)

Powder (freeze dried) 
Components: exo-inulinase 20,000 U (on kestose, at 40^oC), endo-inulinase 650 U (on fructan at 40^oC), α-galactosidase 2.7 U (on p-nitrophenyl α-galactoside at 40^oC), β-Glucanase 1.9 U (on β-glucan at 40^oC) and pectinase 1.2 U (on pectin at 40^oC). 

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 0.013%, 0.009% and 0.006%, respectively. In Fructozyme (NOVO), the contamination by α-galactosidase, β-glucanase and pectinase is 14.2%, 0.2% and 2% respectively.

Stable at -20^oC for > 4 years.
