About additional indices of the raw milk quality

The basis norm of the mass share of protein is considered to be one of the indices of raw milk quality. The arbitration method for determination of the index (according to Kjeldahl) is based on the determination of total nitrogen in milk. However, crude nitrogen is presented both by protein and non-protein nitrogenous complexes that gives possibility to adulterate milk. In this connection it is offered to introduce additional indices of the raw milk quality -to determine levels of non-protein nitrogen, urea and mass share of the true protein.
