Resumo: The Brazilian legislation regulating the research of milk fraud limits the official method for researching ethyl alcohol. Other alcoholic and chemical compounds, potential restorative of the cryoscopy index, can then go unnoticed by the quality control of industries since the official method might not be sufficient in the detection of these compounds. The objective of this study was to verify whether the method of ethanol detection is efficient for the detection of other alcoholic compounds (methanol, propanol, butanol) and acetone, its analytical sensitivity, and the influence on the restorative potential of different concentrations in the cryoscopy index. This study showed that the ethanol research method has analytical sensitivity considered satisfactory (0.01%) and is even better for the research of other alcohols (0.005%) and acetone. The reconstitution of the cryoscopy index of methanol was superior to the other evaluated substances. The presence of ethanol, methanol, propanol, butanol, and acetone in milk indicates that the product has been doubly defrauded: with water and then with one of these substances used to remake cryoscopy and, even at low concentrations, may expose the consumer to risks. The technique recommended by the legislation for research of ethanol in milk proved to be sufficient and sensitive for the detection of ethanol, as well as other alcoholic compounds and acetone, so it can be used by the quality control of industries for the detection of these substances.

Outros compostos alcoólicos e químicos, potenciais reconstituintes do índice crioscópico, podem então passar despercebidos pelo controle da qualidade das indústrias, uma vez que o método oficial poderia não ser suficiente na detecção destes. O objetivo do presente trabalho foi verificar se o método previsto para detecção de etanol é suficiente na detecção de outros compostos alcóolicos (metanol, propanol, butanol) e acetona, a sua sensibilidade analítica e a influência no potencial reconstituinte de diferentes concentrações no índice crioscópico do leite. Este estudo mostrou que o método de pesquisa de etanol possui uma sensibilidade analítica considerada satisfatória (0,01%), e é ainda melhor para a pesquisa dos outros álcoois e acetona (0,005%). O potencial reconstituinte do índice crioscópico do metanol foi superior em relação às outras substâncias avaliadas. A presença de etanol, metanol, propanol, butanol e acetona no leite indica que o produto foi duplamente fraudado: com água e então com uma dessas substâncias utilizadas para recompor a crioscopia e, mesmo em baixas concentrações, podem expor o consumidor a riscos químicos. A técnica recomendada pela legislação para pesquisa de etanol no leite, mostrou-se suficiente e sensível para a detecção de etanol e outros compostos alcoólicos e acetona, e pode ser utilizada pelo controle da qualidade das indústrias para a detecção dessas substâncias.ILCTCNPq e FAPTDias, Bianca PereiraSantos, Isac Gabriel Cunha dosNascimento, Cristiane AlvesLobo, Cátia Maria de OliveiraRibeiro Júnior, José Carlos2022-12-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.revistadoilct.com.br/rilct/article/view/85810.14295/2238-6416.v76i3.858Journal of Candido Tostes Dairy Institute; v. 76, n. 3 (2021); 180-187Revista do Instituto de Laticínios Cândido Tostes; v. 76, n. 3 (2021); 180-1872238-64160100-3674reponame:Revista do Instituto de Laticínios Cândido Tostesinstname:Empresa de Pesquisa Agropecuária de Minas Gerais (EPAMIG)instacron:EPAMIGporhttps://www.revistadoilct.com.br/rilct/article/view/858/563https://www.revistadoilct.com.br/rilct/article/downloadSuppFile/858/397Direitos autorais 2022 Revista do Instituto de Laticínios Cândido Tosteshttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2022-12-28T00:40:40Zoai:oai.rilct.emnuvens.com.br:article/858Revistahttp://www.revistadoilct.com.br/ONGhttps://www.revistadoilct.com.br/rilct/oai||revistadoilct@epamig.br|| revistadoilct@oi.com.br2238-64160100-3674opendoar:2022-12-28T00:40:40Revista do Instituto de Laticínios Cândido Tostes - Empresa de Pesquisa Agropecuária de Minas Gerais (EPAMIG)false
