Resumo
With the objective to evaluate the influence of the stockage time on the presence of
CMP (caseinmacropeptide) in raw milk the raw material after reception for the dairy industrie
was cooled, 4 °C, and stored in 20.000 L isothermal horizontal tank. The tank remained
sealed up during the 72 hours of stockage and in this period the access to this only for
collection of samples with intention was allowed to carry through analyses physicist-
chemistries, microbiological (counting psychrotrophics aerobic) and of chromatography in
HPLC (for whey detention). After the stockage for 72 hours raw milk was destined to the
manufacture of Prato cheese. The Prato cheese was submitted the analyses of humidity,
chloride and pH, sensorial income and for the quantitative descriptive analysis. One
evidenced that the time of stockage of 72 hours is enough for the indication of false positive
of whey presence. To long of the storage time the growth of the counting of psychrotrophics,

the whey since these microrganismos are the responsible ones for proteolysis of κ-casein.
Proteolysis promoted by psychrotrophics is preoccupying for the dairy industry since it can
indicate false positive of fraudulent addition of whey to raw milk besides having an
inadequate raw material for production of milky derivatives. The analyses physicist-
chemistries and of cheese income Prato show that the cooled raw milk use in the production
of related queijo did not modify the quality standards, identity and of market of such product.
The quantitative descriptive analysis showed that samples that samples of produced Prato
cheese with raw milk cooled storaged by 72 hours can negative influence in the attributes
flavor bitter taste and elasticity for proteolysis of the casein.
