Resumo: | During production or storage of dehydrated dairy products, milk constituents may undergo redistribution, resulting in heterogeneity between the surface and its interior. The main objective of this work was to map the surfaces of different dehydrated dairy products, with the combined use of Raman spectroscopy and scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS). It was intended to characterize the surfaces of the particles of interest in both instruments and to perform the mapping of these, within specific populations. The proposal to combine different techniques aimed, in addition to obtaining complementary data, to show that it is possible to advance in the research of dairy products when analyzing the particles under different analytical perspectives. All analyzes were carried out from industrialized products with lots, manufacture and validity dates monitored. From the spectroscopic profiles of the particles, it was possible to verify differences when the set of particles was analyzed, as well the target particles alone. It was possible to perform the characterization of the particles using different analytical techniques providing a data set that expands information about the particles of the dairy powders analyzed. |

O principal objetivo deste trabalho foi realizar o mapeamento das superfícies de diferentes produtos lácteos desidratados, com o uso combinado da espectroscopia Raman e a microscopia eletrônica de varredura (MEV) acoplada à espectroscopia por energia dispersiva (EDS). Caracterizou-se as superfícies das partículas em ambos os instrumentos e realizou-se o mapeamento, dentro de populações específicas. A proposta de associar as diferentes técnicas visou, além de obter dados complementares, mostrar que é possível avançar na pesquisa dos produtos lácteos, quando se analisa as partículas sob diferentes perspectivas analíticas. Todas as análises foram realizadas a partir de produtos industrializados com lotes, datas de fabricação e validade monitoradas. A partir da análise dos perfis espectroscópicos das partículas foi possível verificar diferenças tanto do conjunto de partículas bem como das partículas alvo isoladamente. Foi possível realizar a caracterização das partículas utilizando diferentes técnicas analíticas fornecendo um conjunto de dados que amplia informações acerca das partículas dos pós estudados.ILCTCNPq, CAPES e FAPEMIGToledo, Paulo Henrique de MeloPereira, João Pablo FortesPerrone, Ítalo TulerCarvalho, Antônio FernandesOliveira, Luiz Fernando CappaStephani, Rodrigo2020-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.revistadoilct.com.br/rilct/article/view/75510.14295/2238-6416.v75i1.755Journal of Candido Tostes Dairy Institute; v. 75, n. 1 (2020); 10-21Revista do Instituto de Laticínios Cândido Tostes; v. 75, n. 1 (2020); 10-212238-64160100-3674reponame:Revista do Instituto de Laticínios Cândido Tostesinstname:Empresa de Pesquisa Agropecuária de Minas Gerais (EPAMIG)instacron:EPAMIGporhttps://www.revistadoilct.com.br/rilct/article/view/755/522Direitos autorais 2020 Revista do Instituto de Laticínios Cândido Tosteshttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2020-10-01T04:24:04Zoai:oai.rilct.emnuvens.com.br:article/755Revistahttp://www.revistadoilct.com.br/ONGhttps://www.revistadoilct.com.br/rilct/oai||revistadoilct@epamig.br|| revistadoilct@oi.com.br2238-64160100-3674opendoar:2020-10-01T04:24:04Revista do Instituto de Laticínios Cândido Tostes - Empresa de Pesquisa Agropecuária de Minas Gerais (EPAMIG)false |
