FoodLab: AIA Report on the Analysis of Urea in Milk

From July through October 2001, Standard Latte Laboratory, which is part of the Associazione Italiana Allevatori (Italian Breeders Association) ran 2,500 tests to assess the operation of FoodLab.

The functional tests were aimed at determining the Milk Urea Nitrogen (MUN) of cows, buffalos and sheep.

The following tests were performed:

• Determination of the testing time
• Measurement of the temperature in each well
• Repeatability tests
• System calibration
• Control of system al
• Sensitivity and recovery tests
• Control of the batch variability
• Test aimed at controlling possible interferences with fats
• Dilution tests

Some Conclusions

• FoodLab can be used to determine the concentration of urea with no prior sample processing.
• The thermostating of the 15 wells (37° C ± 0,4° C) was consistent and the differences reported were within the stated tolerance.
• Manual operations had not impact on the results.
• Repeatability was generally good.
