The present work analyzed 150 UHT whole milk samples from three different brands, commercialized in city of Palotina (Paraná, Brazil), between October of 2004 and February of 2005. Mesophilic aerobic bacteria counting results were compared to the Agriculture Ministry of Brazil official standards (RTIQ) for UHT milk. 36 (24%) of the sample presented higher mesophilic bacteria counting according to the standards. Also, were proceeded physic-chemical analyses of those samples. 7.3% of the acidity results, 29% of crude fat and 50.7% of dry matter without fat were disagreeing to RTIQ. All samples accorded to the standards for cryoscopy and alcohol stability tests.Downloads
