Hydrogen peroxide test in milk

The chemical analysis of the milk and dairy products for quality control for every stage of the production chain with CDR FoodLabHydrogen 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.

With the same analyzers you can also perform analysis of egg, tomato, vegetable purees, cheeses and fats.

Method

Test type: End Point.
Testing time: one test 6 minutes
Are possible test sessions with several samples, up to a maximum of 16.
The system is supplied pre-calibrated and ready for use.

Principle of the test

H2O2 + phenolic derivate peroxidase Pink complex

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.

Reagent test Kits

The reagents are packaged in foil pouches containing 10 tubes useful to perform 10 analyses.

This is the minimum package that allows the use of CDR systems even to those who need to make a few analyses, thus not wasting reagents.

There are also boxes of 100 tests, however, packaged in 10 bags of 10 tubes containing the reagent.

Code *300325 suitable for 100 tests

Code *300329 suitable for 10 tests

The reagents have a shelf-life of 12 months.

Processing – Sample volume – Measuring range

Whole or skimmed milk: use as is.

Measuring range
(ppM H2O2)
Sample volume Resolution
(ppM H2O2)
Repeatability
2 – 25 50 µL 0,1 CV<3%

For samples with a value of H2O2 that exceed the measuring range use half of the sample volume and multiply the result by 2.
