As curvas analíticas apresentaram coeficiente de correlação ≥ 0,97. O método foi seletivo para todos os analitos nos quatro tipos de queijo. Os coeficientes de variação (repetitividade) encontraram-se todos abaixo de 10%. A recuperação dos compostos foi superior a 70% em mais de 76% das determinações. O queijo que apresentou melhores índices de recuperação foi o Prato. Os menores limites de detecção e quantificação encontrados foram para a glutamina, 0,07 e 0,22 mg/100 g respectivamente, enquanto os maiores foram para o ácido aspártico, 0,81 e 2,46 mg/100 g. Desta forma o método é adequado para determinação dessas substâncias nos queijos estudados.Performance parameters were presented for anultra high-performance liquid chromatographic method for determination of 19 amino acids, 10 bioactive amines and ammonium ion in Parmesan, Gorgonzola, Prato and Mozzarella cheeses. Analytical curves showed correlation coefficient ≥ 0.97. The method was selective for all analytes in the four types of cheese. The coefficients of variation in a repeatability experiment were all below 10%. The recovery of the compounds was over 70% in more than 76% of the determinations. The cheese with best recovery rates was Prato. The lowest limits of detection and quantification were found for glutamine, 0.07 and 0.22 mg/100g respectively, whereas the highest limits were for aspartic acid, 0.81 and 2.46 mg/100g. Based on these results, the method is suitable for determination of these substances in the cheeses studied.porUniversidade Federal de Minas GeraisUFMGBrasilFAR - DEPARTAMENTO DE ALIMENTOSFAR - DEPARTAMENTO DE PRODUTOS FARMACÊUTICOSRevista do Instituto de Latícinios Cândido TostesAlimentaçãoQuímicaProteóliseValidaçãoEfeito matrizQueijos brasileirosParâmetros de desempenho em método UHPLC-UV para quantificação de aminoácidos livres e aminas bioativas em queijos mussarela, prato, parmesão e gorgonzolaPerformance parameters of a UHPLC-UV method for quantification of free amino acids and bioactive amines in mozzarella, prato, parmesan and gorgonzola cheesesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.revistadoilct.com.br/rilct/article/view/635/449Gisela de Magalhães Machado MoreiraDenise SobralRenata Golin Bueno CostaJunio César Jacinto de PaulaChristian FernandesMaria Beatriz de Abreu Glóriaapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain;
