Resumo: The aim of this study was to evaluate the microbiological quality and pasteurization enzymatic parameters in 80 samples of pasteurized milk produced in the north of Paraná state - Brazil from January, 2004 to December, 2005. The obtained results were compared with legislation established in the Regulation of Industry and Sanitary Federal Inspection of Food of Animal Origin. The microbiological analyses were mesophilic aerobes enumeration, most probable number (MPN) of total coliforms and thermotolerant coliforms. Peroxidase and alkaline phosphatase enzymes were used to evaluate the pasteurization process. Samples disagreeing with the standards were 3,7% to mesophilic aerobes, 30,0% to total coliforms and 14,0% to thermotolerant coliforms. Furthermore, in 16,2% of the samples the peroxidase was not present, indicating overheating, what may affect negatively milk composition. According to the results it could be verified that the microbiological quality of some samples were unsatisfactory.

Os resultados obtidos foram comparados com os padrões estabelecidos no Regulamento da Inspeção Industrial e Sanitária de Produtos de Origem Animal (RIISPOA). As análises microbiológicas realizadas foram: contagem de aeróbios mesófilos, determinação do número mais provável de coliformes totais e coliformes termotolerantes. A avaliação da pasteurização foi realizada a partir da pesquisa das enzimas peroxidase e fosfatase alcalina. As amostras em desacordo com os padrões estabelecidos foram: 3,7% para aeróbios mesófilos, 30,0% para coliformes totais e 14,0% para coliformes termotolerantes. Ainda 16,2% das amostras apresentavam peroxidase negativa, indicando superaquecimento, o que pode causar prejuízos à composição do leite. Com os resultados obtidos podemos concluir que a qualidade microbiológica de parte das amostras foi insatisfatória.UEL2007-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/296810.5433/1679-0359.2007v28n3p449Semina: Ciências Agrárias; Vol. 28 No. 3 (2007); 449-454Semina: Ciências Agrárias; v. 28 n. 3 (2007); 449-4541679-03591676-546Xreponame:Semina.
