Abstract

In the present research work, the quality control of a milk collection center was carried out crude CA2., located in the province of Chimborazo canton Riobamba. Compliance was verified of the procedure’s manual issued by Agrocalidad, the physical-chemical analyzes were carried out in the Lactoscan MCCW equipment and for the microbiological analysis the counting technique was applied in plate on surface and in depth. The physical-chemical analysis shows a breach of the standard NTE INEN 9: 2012 in the parameters: lactose, salts, freezing point and pH. The results of the check lists show a non-compliance of 19% (collection center) and 7.69% (carrier). The high content of microorganisms: Enterobacteriaceae (6.24 to 6.93 log CFU / ml), aerobic bacteria mesophilic (7.31 to 7.35 log CFU / ml), Staphylococcus areus. (6.11 to 6.40 log CFU / ml), moulds and yeasts (5.08 to 5.23 log CFU / ml) show poor sanitary quality of raw milk, on the other side, lactic acid bacteria, lactobacillus (6.28 to 6.49 log CFU / ml) and lactococcus (6.48 at 7.11 CFU / ml) are beneficial for the dairy industry. In conclusion, there are no good hygienic-sanitary conditions in the raw milk of the CA2. collection center, for which it is recommended training staff and producers on good hygiene practices, which should be controlled from milking, reception to the raw milk storage plant in order to guarantee the safety of the product.
