Abstract
La calidad de la leche cruda depende del manejo, alimentación y sanidad prioritariamente. El objetivo del trabajo es evaluar la calidad fisicoquímica y sanitaria de la leche cruda bovina de la asociación ASOPROLEA M.C. Los análisis se realizaron con el equipo LactoStar (c) 2008 Funke Gerber y TRAM. Se determinó 17.44±2.06 y 16.22±4.22 de acidez Dornic, 1.025±0.002 y 1.030-1.034 g/cm³ de densidad, 6.55±0.55 y 6.71±0.36 de pH, 10.25±0.3 y 9.80±0.54 % de solidos totales, 3.65±0.56 y 3.55±0.60 % de grasa, 2.82±0.11 y 2.66±0.21% de proteína, 4.05±0.4 y 3.90±0.35% de lactosa, 0.75±0.05 y 0.73±0.15% de minerales para tacho y tanque respectivamente. En cuanto al TRAM 48.2 % de las muestras colectadas se reduce en menos de 2 h y el 51.8 % es leche que reduce el azul de metileno después de 3 o más h. La mayor fuente de problemas pareciera ser la contaminación microbiana en la leche entregada por los productores de la comunidad Mazo Cruz y sería necesario hacer un seguimiento más cercano al tanque de enfriamiento.
The milk quality depend of a good feeding, good health and adequate management. The aim of this research was to evaluate the physical, chemical and sanitary characteristics of bovine milk from ASOPROLEA M.C. it was determinated 17.44±2.06 and 16.22±4.22 of ºDornic, 1.025±0.002 and 1.030 to 1.034 g/cm³ of density, 6.55±0.55 and 6.71±0.36 of pH, 10.25±0.3 and 9.80±0.54 % of total solids, 3.65±0.56 and 3.55±0.60 % of fat, 2.82±0.11 and 2.66±0.21 % of protein, 4.05±0.4 and 3.90±0.35% of lactose, 0.75±0.05 and 0.73±0.15% of minerals for milkcan and milktank respectively. About TRAM 48.2 % of samples are reducted in less than 2 h and 51.8 % of milk samples are reducted in more than 3 h. The high problem seems to be the microbial contamination in milkcans and in the milktank of this community, it could be necessary to review the milktank.
