Resumo: | The present work aimed to evaluate the adjustments to the mathematical models of the drying kinetics of lemongrass leaves in a convective dryer at 40, 55 and 70 ° C, with drying air velocities of 1.0, 1.5 and 2.0 m / s by factorial design 22 + 3 experiments at the central point. The fresh leaves were subjected to chemical, physical and physicochemical characterization. The drying kinetics was performed in a convective dryer, with adjustments for four mathematical models, being considered as fit quality criterion, the determination coefficients (R2) and the mean square deviations (DQM). After the drying tests, one can highlight the three test conducted at a temperature of 40 ° C and a speed of 1.0 m / s, presenting higher yield and lower water content, the resulting powder was subjected to analysis of: granulometry , water content, water activity, ashes, wettability, hygroscopicity, solubility, specific mass, specific compaction mass, Hausner factor, compressibility index, color, flavonoids, total and b chlorophylls, carotenoids and tannins. The models presented satisfactory adjustments to the drying kinetics, with R²> 99.0% and DQM <0.02, especially the Cavalcanti Mata model. The drying process used was efficient resulting in a soluble, little hygroscopic and fine powder with bioactive concentrations relevant for its medicinal use. |

Las hojas frescas se sometieron a caracterización química, física y fisicoquímica. La cinética de secado se realizó en un secador convectivo, con ajustes para cuatro modelos matemáticos, considerándose como criterio de calidad de ajuste, los coeficientes de determinación (R2) y las desviaciones cuadráticas medias (DQM). Después de las pruebas de secado, se pueden resaltar las tres pruebas realizadas a una temperatura de 40 ° C y una velocidad de 1.0 m / s, presentando mayor rendimiento y menor contenido de agua, el polvo resultante se sometió a análisis de: granulometría , contenido de agua, actividad del agua, cenizas, humectabilidad, higroscopicidad, solubilidad, masa específica, masa específica de compactación, factor de Hausner, índice de compresibilidad, color, flavonoides, clorofilas totales y b, carotenoides y taninos. Los modelos presentaron ajustes satisfactorios a la cinética de secado, con R²> 99.0% y DQM <0.02, especialmente el modelo Cavalcanti Mata. El proceso de secado utilizado fue eficiente, dando como resultado un polvo soluble, poco higroscópico y fino, con concentraciones bioactivas relevantes para su uso medicinal.O presente trabalho teve como objetivo avaliar os ajustes aos modelos matemáticos da cinética de secagem de folhas de erva cidreira em secador convectivo nas temperaturas de 40, 55 e 70°C, com velocidades de ar de secagem de 1,0, 1,5 e 2,0 m/s mediante planejamento fatorial 22 + 3 experimentos no ponto central. As folhas in natura foram submetidas as caracterizações químicas, físicas e físico-químicas. A cinética de secagem foi realizada em secador convectivo, com ajustes para quatro modelos matemáticos, sendo considerado como critério de qualidade de ajuste, os coeficientes de determinação (R2) e os desvios quadráticos médios (DQM). Após realização dos ensaios de secagem, pode-se destacar o ensaio três conduzido com temperatura de 40 °C e velocidade de 1,0 m/s, apresentando maior rendimento e menor teor de água. O pó resultante foi submetido as análises de: granulometria, teor de água, atividade de água, cinzas, molhabilidade, higroscopicidade, solubilidade, massa específica, massa específica de compactação, fator de Hausner, índice de compressibilidade, cor, flavonoides, clorofilas a, b e total, carotenoides e taninos. Os modelos apresentaram ajustes satisfatórios à cinética de secagem, com R² > 99,0% e DQM <0,02, destacando-se o modelo de Cavalcanti-Mata. O processo de secagem utilizado foi eficiente resultando em um pó solúvel, pouco higroscópico e fino, com concentrações de bioativos relevantes para seu uso medicinal.Research, Society and Development2020-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/205210.33448/rsd-v9i2.2052Research, Society and Development; Vol. 9 No. 2; e86922052Research, Society and Development; Vol. 9 Núm. 2; e86922052Research, Society and Development; v. 9 n. 2; e869220522525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/2052/1726Copyright (c) 2019 Thais Jaciane Araujo Rodrigues, Mayara Eunice de Macedo Gomes, Aline Pacheco Albuquerque, Dannyelle Macedo Albuquerque Wanderley, Ana Paula Trindade Rocha, Osvaldo Soares da Silvainfo:eu-repo/semantics/openAccessGomes, Mayara Eunice de MacedoAlbuquerque, Aline PachecoRodrigues, Thais Jaciane AraújoWanderley, Dannyelle Macedo AlbuquerqueRocha, Ana Paula TrindadeSilva, Osvaldo Soares da2020-08-20T18:08:48Zoai:ojs.pkp.sfu.ca:article/2052Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:26:50.606334Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
