Hydrogen peroxide in milk
 |
Hydrogen peroxide is used as a sanitizer of the machinery used for milk treatment. The presence of hydrogen peroxide inside the machinery may contaminate the milk: the scope of the test is the determination of its presence since it would determine milk contamination. The test is also used to determine an addition of hydrogen peroxide in raw milk, before undertaking pasteurization, to increase its duration.
Instrument
Reagents
R1 (pre filled in test tube): phenolic derivatives - phosphate stopper
R2 (dropper): Peroxides
Test method
Test type: End Point
Colour reading at 505 nm
Test time: 5-8 minutes
It is possible to carry out several test sessions with a maximum of 14 samples.
Calibration can be performed by aligning the test to reference values.
Test principle
Hydrogen peroxide, in presence of the peroxides, reacts with a phenolic derivative and forms a pink complex whose intensity, measured at 505 nm, is directly proportional to the concentration of hydrogen peroxide in the sample. The innovative method of CDR is simple, fast, and utilizes a microquantity of the samples.
Sample
Milk as is.
Kit
The reagents are provided in sealed bags, each containing 10 test tubes. They have a 12 months duration, starting from the production date. Stocking requirements are described on the bag label.
Reagents do not contain dangerous solvents and are ready for use.
