Resumo: | The objective was to evaluate the physical-chemical, microbiological and labeling of seven brands of pasteurized milk marketed in regions near the city of Ubá – Minas Gerais. We performed physical and chemical analyzes of acidity, lactose, fat, protein, EST, ESD, pH, density, cryoscopic point, humidity and cooking, as well as microbiological analysis of total and fecal coliforms and standard plate count. For physical-chemical analyzes, the following average results were obtained: 16ºD for titratable acidity, 4,61% for lactose, 3,21% for fat, 3,11% for protein, 11,63% for EST, 8,39% to ESD, pH 6,76, 1,030g / ml for specific density at 15ºC -0.531 ºH to freezing point. Of the seven samples analyzed one showed the presence of water in three batches analyzed in an average ratio of 4,06%; 28,57% of the samples were clotting in the cooking test, being observed significant difference (p 0.05) for most physical and chemical parameters. As for microbiological analyzes we found average 3,0 NMP / mL and 1.100 NMP / mL for total and fecal coliforms respectively and average 2,6x104 CFU/ml for aerobic mesophilic. Regarding the analysis of labeling only two samples (28,57%) found to comply with all listed and existing requirements for food labeling. Thus, it is concluded that pasteurized milk marketed in the region of Ubá show differences in their physical and chemical composition and microbiological quality. |

Foram realizadas análises físico-químicas de acidez, lactose, gordura, proteína, EST, ESD, pH, densidade, ponto crioscópico, umidade e cocção, bem como análises microbiológicas de coliformes totais e termotolerantes e contagem padrão em placas. Para as análises físico-quimicas, foram obtidos os seguintes resultados médios: 16ºD (0,16g de ácido lático/100g de produto) para acidez titulável, 4,61% para lactose, 3,21% para gordura, 3,11% para proteína, 11,63% para EST, 8,39% para ESD, pH de 6,76, 1,030g/mL para densidade relativa a 15ºC, -0,531 ºH para crioscopia. Das sete amostras analisadas uma apresentou presença de água nos três lotes analisados (média de 4,06% de água). Cerca de 28,57% das amostras apresentaram coagulação no teste de cocção. Foi observado diferença significativa (p 0,05) para a maioria dos parâmetros físico-químicos. Quanto às análises microbiológicas foram encontrados valores variando de 3,0 NMP/mL a 1.100 NMP/mL tanto para coliformes totais quanto para termotolerantes. Para mesófilos aeróbios a média encontrada foi de 2,6x104 UFC/mL de leite. Com relação à análise de rotulagem apenas duas amostras (28,57%) encontraram-se em conformidade com todas as exigências listadas e vigentes para rotulagem de alimentos. Desta forma, conclui-se que os leites pasteurizados comercializados na microrregião de Ubá apresentam diferenças quanto sua composição físico-química e qualidade microbiológica.ILCTOliveira, Aryane da LuzVaneli, Neumara RibeiroVargas, Pamela de OliveiraMartins, Aurélia Dornelas de OliveiraCócaro, Elaine SouzaCoelho, Antônio Daniel Fernandes2015-02-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.revistadoilct.com.br/rilct/article/view/45410.14295/2238-6416.v70i6.454Journal of Candido Tostes Dairy Institute; v. 70, n. 6 (2015); 301-315Revista do Instituto de Laticínios Cândido Tostes; v. 70, n. 6 (2015); 301-3152238-64160100-3674reponame:Revista do Instituto de Laticínios Cândido Tostesinstname:Empresa de Pesquisa Agropecuária de Minas Gerais (EPAMIG)instacron:EPAMIGporhttps://www.revistadoilct.com.br/rilct/article/view/454/390https://www.revistadoilct.com.br/rilct/article/downloadSuppFile/454/94Direitos autorais 2017 Revista do Instituto de Laticínios Cândido Tosteshttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2017-08-31T20:44:26Zoai:oai.rilct.emnuvens.com.br:article/454Revistahttp://www.revistadoilct.com.br/ONGhttps://www.revistadoilct.com.br/rilct/oai||revistadoilct@epamig.br|| revistadoilct@oi.com.br2238-64160100-3674opendoar:2017-08-31T20:44:26Revista do Instituto de Laticínios Cândido Tostes - Empresa de Pesquisa Agropecuária de Minas Gerais (EPAMIG)false |
