Megazyme® Fructanase Mixture (liquid)
10 ml / 20,000 Units
SKU 编号 700004215 | 目录编号 E-FRMXLQ
AOAC OMA
High purity Fructanase Mixture (liquid) for use in research, biochemical enzyme assays and analytical testing applications.
Components: exo-inulinase 2,000 U/ml (on kestose, at 40°C), endo-inulinase ˜ 100 U/ml (on fructan at 40°C), α-galactosidase < 0.08 U/ml (on polygalacturonic acid at 40°C), β-Glucanase < 0.04 U/ml (on β-glucan at 40°C) and pectinase < 0.07 U/ml (on pectin 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.
Fructanase and sucrase (E-SUCR) may also be utilized in the enzymatic hydrolysis of fructans during analytical procedures designed to quantify fructan content in food samples according to the relevant AOAC and GB standard methods.
