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.
