Enzymatic Determination of Residual Hydrogen Peroxide in Milk

摘要: Abstract A method for enzymatically detecting hydrogen peroxide at low levels in milk was developed. It involved the use of horseradish peroxidase with o -dianisidine as a ehromogenic donor. The curd precipitated pH 4.5 hydrochloric acid and whey added to mixture chromogen. amount color developed (measured 400m μ ) result enzymatic reaction gave measurement peroxide. detected less than 1μg/milliliter milk.
