Lactoperoxidase

- enzyme naturally found in milk of most mammals - converts thiocyanate (in the presence of H2O2) to hypothiocyanate - must add activator (mix of thiocyanate and a source of H2O2) - hypothiocyanate reacts with sulfhydryl group of enzymes - hypothiocyanate inactivates bacterial metabolic enzymes - microbial quality stabilized for 24hr @ 15 C, 6-8hr at 30 C
