CDR FoodLab® is the chemical analyzer for quality and process control that allows you to determine a wide range of parameters of many foods, animal feeds and pet foods.

Hydrogen peroxide test in milk

Hydrogen peroxide is used as a sanitizing of milk handling equipment. The presence of hydrogen peroxide can contaminate the milk. The purpose of the test is to detect any traces inside the product. This test also allows to check the possible addition of hydrogen peroxide in raw milk, before pasteurization, to increase its shelf-life.

Method

Principle of the test

Reaction involved in the analysis for the search for hydrogen peroxide in milk

Hydrogen peroxide reacts with a phenolic derivate and peroxidase, and forms a pink colored complex whose intensity measured at 505 nm, is directly proportional to the concentration of hydrogen peroxide (H2O2) in the sample. (H2O2)

Correlation Data

Comparative tests on samples of fresh milk, where H2O2 standard solution was added, confirmed a very good alignment between CDR Foodlab® method and reference method.
