Resumo: The mucilage of Pereskia aculeata Miller is a hydrocolloid with the potential to be used as a food additive. Thus, data on its physical, chemical and microbiological stability are necessary to evaluate the storage stability of the product. This study aimed to determine the thermodynamic properties of water vapor adsorption onto freeze-dried ora-pro-nobis mucilage (OPNM) and to interpret the mechanisms that govern water adsorption onto powder particles through the study of enthalpy-entropy compensation. In addition, OPNM was characterized in terms of moisture, ash, ether extract, protein, fiber and carbohydrates beyond the functional chemical groups by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). Thermodynamic analysis showed that water adsorption onto OPNM powder was characterized as a spontaneous process with strong attractive forces in the water and OPNM mixture. The water sorption mechanism for OPNM at the studied adsorption range was regulated by energy interactions related to the chemical composition of the product.

Assim, obter informações a respeito de sua estabilidade física, química e microbiológica são necessários para avaliar a estabilidade de armazenamento do produto. Este estudo teve como objetivo determinar as propriedades termodinâmicas de adsorção de vapor de água em mucilagem de ora-pro-nóbis liofilizada (OPNM) e interpretar os mecanismos que governam a adsorção de água em partículas do pó através do estudo da compensação de entalpia-entropia. Além disso, OPNM foi caracterizado em termos de umidade, cinzas, extrato etéreo, proteínas, fibras e carboidratos bem como os grupos químicos funcionais por espectroscopia de infravermelho por transformada de Fourier (FTIR) e microscopia eletrônica de varredura (MEV). A análise termodinâmica mostrou que a adsorção de água no pó de OPNM foi caracterizada como um processo espontâneo com fortes forças atrativas na mistura água e OPNM. O mecanismo de sorção de água para OPNM na faixa de adsorção estudada foi regulado por interações energéticas relacionadas à composição química do produto.Universidade Federal de Viçosa - UFV2023-08-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1620010.18540/jcecvl9iss6pp16200-01eThe Journal of Engineering and Exact Sciences; Vol. 9 No. 6 (2023); 16200-01eThe Journal of Engineering and Exact Sciences; Vol. 9 Núm. 6 (2023); 16200-01eThe Journal of Engineering and Exact Sciences; v. 9 n. 6 (2023); 16200-01e2527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVenghttps://periodicos.ufv.br/jcec/article/view/16200/8080Copyright (c) 2023 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessNascimento, Bruna de SouzaBatista , Giovanni AleixoPravato , Vinicius TessinariAlexandre, Gabriel Pedroso de LimaVeríssimo, Lizzy Ayra AlcântaraResende, Jaime Vilela de2024-03-26T17:21:54Zoai:ojs.periodicos.ufv.br:article/16200Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2024-03-26T17:21:54The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false
