Relationship between freezing point and raw ewes’ milk components as a possible tool for estimation

Popis výsledku v původním jazyce

Milk adulteration with added water (MAAW) is controlled by freezing point depression (FPD) determination. The goal was to evaluate the suitability an alternative method for FPD equivalent (FPD-E) measurement and to estimate the basis for FPD cut-off value (to identify MAAW) for sheep´s milk. Raw bulk sheep´s milk samples (BSMSs; n = 811) were analysed for FPD, FPD-E and composition in 2014. The mean FPD of BSMSs was -0.559 ± 0.029 °C. The FPD cut-off value can be in the range close to -0.511 °C (mean + standard deviation x 1.64, one-sided 95% confidence interval). Influence of season and lactation was significant for all milk indicators. 89.4% of the variability in the FPD-E can be explained by variations in FPD. The total correlation coefficient was 0.945 (P < 0.001) and high correlation was also in FPD interval > -0.511 °C: 0.992, P < 0.001. High correlations between FPD and milk components: -0.228, -0.231, -0.219 (P < 0.01), -0.497 and -0.341 (P < 0.001) for fat, protein, lactose, solids not fat and total solids is the explanation. Determination of FPD-E in sheep´s milk can be an effective tool for estimation of MAAW.
