Quality of UHT whole milk marketed in Pernambuco, Brazil

Abstract

The objective of this study was to evaluate the physical-chemical properties and microbiological quality of Ultra-high temperature (UHT) whole milk marketed in Pernambuco state, Brazil. In total, 390 samples of UHT whole milk were purchased from commercial establishments located in the mesoregions of Pernambuco, and transported to the Laboratory of Meat and Milk Inspection at the Federal Rural University of Pernambuco. The physical-chemical analyses and the microbiological evaluations were carried out in order to meet specific legislative mandates. All 13 brands tested met the determined physical-chemical standards. However, it was found that 105 (26.9%) samples did not meet microbiological standards. It is important to highlight the need for further development of integrated actions involving the inspection bodies and the processing plants, in order to adjust the product to the quality standards established in the legislation, respecting the rights and health of consumers.
