In this work a new improvement for lactose determination is assessed in terms of reproducibility, accuracy and recovery. New method and traditional enzymatic method are also taken into comparisonon adding determined aliquotes of lactose in reallactose-free matrices. The new method, that is in CDR FoodLab®, appears to be
The presence of lactic acid or lactate in milk is due to the fermentation of lactose caused mainly by lactic bacteria. Generally speaking, just-milked milk does not contain lactic acid, but this increases after a while and its concentration is closely correlated to the total bacterial charge.

From July through October 2001, Standard Latte Laboratory, which is part of the Associazione Italiana Allevatori (Italian Breeders Association) ran 2,500 tests in order to check FoodLab method in determining the amount of urea in the milk of cows, buffalos and sheeps. This test validates the analysis method of all the analysis systems of the FoodLab Line, the FoodLab method, comprising the new versions of the systems: CDR BeerLab® and Junior, WineLab Touch, FoodLab Touch and FoodLab Touch for fats and oils.
