This paper presents the data of a cross-sectional study on the commercial quality of fresh cow's milk marketed in Iasi. The biological material came from three bovine farms, distributed in the chilled state through milk dispensers. From each source, two litres of milk, in sterile containers, were purchased for five consecutive days, from which the laboratory samples were homogenized and maintained until the analysis, as indicated by the manufacturers. Ten samples were dosed from each farm and subjected to physiochemical analysis by means of isometric, gravimetric, titrimetric, potentiometric and ultrasonometric methods. Regarding the freshness indicator, acidity, the highest value was obtained for the milk of the F3 group where the average was 18.1 ± 0.21°T, while for the milk of the group F1 and F2 the mean values were 16.28 ± 0.20°T and 17.24 ± 0.31°T respectively. Regarding the chemical composition, determinations were made for the determination of SUNG, GB, PB and lactose. In terms of fat content, the mean values were 4.05 ± 0.01% for F1, 3.27 ± 0.01% for F2 and 4.03 ± 0.01% for milk from F3. The milk was not suspected of being falsified because no added water was detected in the analyzed samples and the density was within the normality range of at least 1.029 g/cm3. The results of the researches carried out indicated that the marketed milk is in compliance with the quality standard in force, even if there were significant differences between the qualitative parameters analyzed.
