Resumo: | He interest in donkey milk has been highlighted due to studies related to its beneficial characteristics, it has similarities in palatability and composition when compared to breast milk. Milk of this species has been shown to be low in protein and fat, and rich in lactose, in addition to having antimicrobial properties, making it an ideal food for human supplement and mainly as an alternative food for children with allergy to cow's milk protein. Therefore, the objective of this work was to study the lyophilization kinetics for donkey milk submitted to different freezing temperatures (-20, -60, -100 and -140ºC), as well as to determine the effective diffusivity and thermodynamic properties. The experimental data were subjected to analysis of the theoretical, semi-theoretical, semi-empirical and empirical drying models, and the parameters R2, Ra2, P (%), SE and DQM were determined. Among the drying models studied, the modified Cavalcanti-Mata model was the one that presented the best adjustment to the experimental data. In the models of Fick modified, Cavalcanti-Mata modified, Lewis modified and Page modified, the effective diffusivity decreased with the decrease of the freezing temperature and as a result of this, it appears that enthalpy and entropy decreased as the freezing temperature dropped and Gibbs' free energy demonstrated that the process is not spontaneous. |

Se ha demostrado que la leche de esta especie es baja en proteínas y grasas, y rica en lactosa, además de tener propiedades antimicrobianas, lo que la convierte en un alimento ideal para el complemento humano y principalmente como alimento alternativo para niños con alergia a la proteína de la leche de vaca. Por tanto, el objetivo de este trabajo fue estudiar la cinética de liofilización de la leche de burra sometida a diferentes temperaturas de congelación (-20, -60, -100 y -140ºC), así como determinar la difusividad efectiva y propiedades termodinámicas.. Los datos experimentales fueron sometidos a análisis de los modelos de secado teórico, semisoteórico, semi-empírico y empírico, y se determinaron los parámetros R2, Ra2, P (%), SE y DQM. Entre los modelos de secado estudiados, el modelo Cavalcanti-Mata modificado fue el que presentó el mejor ajuste a los datos experimentales. En los modelos de Fick modificado, Cavalcanti-Mata modificado, Lewis modificado y Page modificado, la difusividad efectiva disminuyó con la disminución de la temperatura de congelación y como resultado, parece que la entalpía y la entropía disminuyeron a medida que descendió la temperatura de congelación y la energía libre de Gibbs demostró que el proceso no es espontáneo.O interesse no leite de asinino vem destacando-se devido a estudos relacionados às suas características benéficas, apresenta semelhanças na palatabilidade e composição quando comparado ao leite materno. O leite dessa espécie demonstrou ser pobre em proteínas e gorduras, e rico em lactose, além de apresentar propriedades antimicrobianas, tornando-o um alimento ideal para suplemento humano e principalmente como alimento alternativo para crianças com alergia à proteína do leite de vaca. Diante disso, o objetivo deste trabalho foi estudar a cinética de liofilização para o leite asinino submetido a diferentes temperaturas de congelamento (-20, -60, -100 e -140ºC), bem como determinar a difusividade efetiva e as propriedades termodinâmicas. Os dados experimentais foram submetidos a analises dos modelos de secagem teórico, semiteórico, semiempíricos e empírico, e os parâmetros R2, Ra2, P (%), SE e DQM foram determinados. Dentre os modelos de secagem estudados o Modelo de Cavalcanti-Mata modificado, foi o que apresentou melhor ajuste aos dados experimentais. Nos modelos de Fick modificado, Cavalcanti-Mata modificado, Lewis modificado e Page modificado, a difusividade efetiva decresceu com a diminuição da temperatura de congelamento e em consequência disto, constata-se que a entalpia e a entropia diminuiu a medida que a temperatura de congelamento foi baixando e a energia livre de Gibbs demonstrou que o processo não é espontâneo.Research, Society and Development2021-02-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1291010.33448/rsd-v10i2.12910Research, Society and Development; Vol. 10 No. 2; e46310212910Research, Society and Development; Vol. 10 Núm. 2; e46310212910Research, Society and Development; v. 10 n. 2; e463102129102525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/12910/11487Copyright (c) 2021 Francisca Moisés de Sousa; Mário Eduardo Rangel Moreira Cavalcanti-Mata; Maria Elita Martins Duarte; Mylena Olga Pessoa Melo; Manoel Tolentino Leite Filho; Rebeca Morais Silva Santos ; Michelly Daiane Araújo de Almeida; Anastácia Maria Mikaella Campos Nóbrega André; Alexandre da Silva Lúcio; Kamila de Lima Santos; Jorge Jacó Alves Martins ; Larissa Monique de Sousa Rodrigueshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSousa, Francisca Moisés de Cavalcanti-Mata, Mário Eduardo Rangel MoreiraDuarte, Maria Elita Martins Melo, Mylena Olga Pessoa Leite Filho, Manoel Tolentino Santos , Rebeca Morais Silva Almeida, Michelly Daiane Araújo de André, Anastácia Maria Mikaella Campos Nóbrega Lúcio, Alexandre da Silva Santos, Kamila de Lima Martins , Jorge Jacó Alves Rodrigues, Larissa Monique de Sousa 2021-03-02T09:32:39Zoai:ojs.pkp.sfu.ca:article/12910Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:34:22.014707Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
