Simple, Accurate Method to Determine Hydrogen Peroxide in Honey

Rapid Determination of Hydrogen Peroxide Using Peroxidase Immobilized on Amberlite IRA-743 and Minerals in Honey
J. Agric. Food Chem, 55 (17), 6885 -6890, 2007 (July 28, 2007)

Abstract: Hydrogen peroxide and trace metals (K+, Ca2+, Na+, Mg2+, Mn2+, and Li+) were determined in 14 samples of Brazilian commercial honeys. The method for the determination of H2O2 is based on selective oxidation of H2O2 using an on-line tubular reactor containing peroxidase immobilized on Amberlite IRA-743 resin.

Reactors presented high stability for at least 2 weeks under intense use. The results show a simple, accurate, selective, and readily applied method to the determination of H2O2 in honey…
