The urea content in raw milk is related to the amount of protein in the animal feeding and allows you to define an adequate diet. This analysis also helps to identify any additions of urea in milk, introduced in order to increase, fraudulently, the protein content of milk.
Features of Milk Urea Nitrogen (MUN) test in milk and dairy products
- Test time 3 minutes
- NO skilled staff required nor a laboratory for the analysis.
- Results are correlated with reference method results.
- It is free of service and NO maintenance cost.

Urea + der. Fenolico a blue-green colored complex
The urea is converted into ammonia by urease enzyme. The ammonium ions react with a phenolic derivative and form a blue-green colored complex whose intensity, measured at 700 nm, is directly proportional to the concentration of urea in the sample.
Comparative tests, on samples of whole milk performed between the reference method (differential pH-metry instrument – EFA Instrument) and the FoodLab method, made in “Laboratorio Standard Latte” of the AIA (Italian Breeders Association) have confirmed a very good alignment between the two systems
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.
Reagent test kit *300000 suitable for 100 tests
Reagent test kit *300004 suitable for 10 tests
The reagents have a shelf-life of 12 months.
