Abstract

Cow’s milk is an integral product that provides essential nutrients for health, and it is consumed worldwide. In Ecuador, the INEN 9:2015 (Ecuadorian Institute for Standardization), standards establish quality standards for production, distribution and marketing. They are supervised by Agrocalidad and ARCSA, which guarantees that the milk is fit for consumption. However, these practices are unknown to small producers. Therefore, in the present study, the milk quality (physicochemical properties, microbiological analysis and organoleptic tests) was determined in different rural areas of Suscal livestock farms, province of Cañar. The data was analyzed using a multifactorial ANOVA using SAS. The separation of means, the Tukey test was used at a significance level (P<0,05). And the Pearson correlation test was performed. The results were, in physicochemical properties: the average acidity of 14.25 °D; protein of 3.13 %; and fat of 4.03 %. In the microbiological analysis: the mesophilic aerobes in solution -4 were 74.37 CFU and 162.03 CFU at 24 and 48 hours respectively; and somatic cells of 243333.33 u/cm³. In organoleptic characteristics: the color was opalescent white and slightly yellowish; the smell was milky smooth and free of strange odors; and the texture of the milk was homogeneous and free of foreign matter. Finally, total solids are highly correlated with protein and fat, which is positive.
