Resumo: | This study aimed to evaluate the physicochemical characteristics of freeze-dried Araçá-boi powder, and its hygroscopic behavior using adsorption isotherms and different mathematical models. The Araçá-boi pulp formulations with different concentrations of maltodextrin (14, 21 and 28%) were frozen in a freezer at -18 ° C, then dehydrated in a bench-top freeze dryer. The parameters of water content, total solids, pH and titratable acidity were determined. The water adsorption isotherms of Araçá-boi powder at temperatures of 25, 30 and 35 °C were determined using the special indirect static method, using the Aqualab hygrometer, to measure water activity. The Henderson, Oswin, Halsey, GAB and Peleg models were fitted to the water adsorption isotherms using nonlinear regression. From the coefficient of determination (R2) and the mean percentage deviation (P), it was found that, among the models studied and considering the temperatures tested, the R2 values obtained in GAB, Halsey and Peleg are so close to each other that , in the worst case, they do not exceed a 0.9% difference. The best mathematical representation of the isotherms was obtained by the GAB model, since it presented the lowest values for Xm, being, therefore, the model that best explains the water gain. |

As formulações da polpa de Araçá-boi com diferentes concentrações de maltodextrina (14, 21 e 28%) foram congeladas em freezer à -18 °C, em seguida, desidratadas em liofilizador de bancada. Foram determinados os parâmetros de teor de água, sólidos totais, pH e acidez titulavel. As isotermas de adsorção de água do pó de Araçá-boi nas temperaturas de 25, 30 e 35 °C foram determinadas usando o método especial indireto estático, utilizando o higrômetro Aqualab, para medir a atividade de água. Os modelos de Henderson, Oswin, Halsey, GAB e Peleg foram ajustados às isotermas de adsorção de água utilizando regressão não linear. A partir do coeficiente de determinação (R2) e do desvio percentual médio (P), verificou-se que, entre os modelos estudados e considerando as temperaturas testadas, os valores de R2 obtidos em GAB, Halsey e Peleg estão tão próximos entre si que, no pior dos casos, não superam 0,9% de diferença. A melhor representação matemática das isotermas foi obtida pelo modelo de GAB, uma vez que apresentou os menores valores para Xm, sendo, portanto, o modelo que melhor explica o ganho de água.Research, Society and Development2021-07-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1651510.33448/rsd-v10i9.16515Research, Society and Development; Vol. 10 No. 9; e24810916515Research, Society and Development; Vol. 10 Núm. 9; e24810916515Research, Society and Development; v. 10 n. 9; e248109165152525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/16515/16120Copyright (c) 2021 Romário Oliveira de Andrade ; Nadson Libio Bezerra Ferreira; Gustavo Santos de Lima; Ana Raquel Carmo de Lima; Caio Franklin Vieira de Figueiredo; Eduardo Henrique Santos de Lima; Saul Ramos de Oliveira; Edilayane da Nóbrega Santos; Josivanda Palmeira Gomes; Ana Paula Trindade Rocha; Gilsandro Alves da Costa; Anderson Ferreira Vilelahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessAndrade , Romário Oliveira de Ferreira, Nadson Libio BezerraLima, Gustavo Santos de Lima, Ana Raquel Carmo de Figueiredo, Caio Franklin Vieira de Lima, Eduardo Henrique Santos de Oliveira, Saul Ramos de Santos, Edilayane da Nóbrega Gomes, Josivanda PalmeiraRocha, Ana Paula Trindade Costa, Gilsandro Alves da Vilela, Anderson Ferreira 2021-09-12T14:28:06Zoai:ojs.pkp.sfu.ca:article/16515Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:37:02.601120Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
