Megazyme E-FRMXPD: Fructanase Mixture (powder)
Product code: E-FRMXPD
Powder (freeze dried)
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.
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).
Fructanase and sucrase (E-SUCR) are used in the enzyme hydrolysis step of the AOAC method 2016.06 and the Chinese GB Standard 5009.255-2016 for the determination of fructan in foods.
