Resumo: | The food packaging process is of immense importance when it comes to preserving fresh or processed foods. Most of these materials are made from synthetic plastics and their disposal represents an environmental problem. This study aimed to prepare and characterize films composed of biopolymers, sodium alginate (SA) and carboxymethylcellulose (CMC), with the addition of arabic gum and fennel essential oil. Contact angle analysis shows that the films are hydrophilic. The surface of the films presented a firm, dense and cohesive structure, but with some roughness. In the micrographs of the film samples containing fennel essential oil, crystal-like structures can be observed on the polymer matrix of CMC and AS. The humidity of the films was, in general, low (average of 14%). The lowest percentages of moisture presented were for films with essential oil. Films are biodegradable, this process occurs because natural macromolecules such as proteins, polysaccharides, cellulose and gum are generally degradable in biological systems by hydrolysis followed by oxidation. Therefore, the formation of edible packaging containing polysaccharides and fennel essential oil emulsion was satisfactory. |

La mayoría de estos materiales están hechos de plásticos sintéticos y su eliminación representa un problema ambiental. Este estudio tuvo como objetivo preparar y caracterizar películas compuestas por biopolímeros, alginato de sodio (SA) y carboximetilcelulosa (CMC), con la adición de goma arábiga y aceite esencial de hinojo. El análisis del ángulo de contacto muestra que las películas son hidrófilas. La superficie de las películas presentó una estructura firme, densa y cohesiva, pero con cierta rugosidad. En las micrografías de las muestras de película que contienen aceite esencial de hinojo, se pueden observar estructuras similares a cristales en la matriz polimérica de CMC y AS. La humedad de las películas fue, en general, baja (promedio de 14%). Los menores porcentajes de humedad presentados fueron para películas con aceite esencial. Las películas son biodegradables, este proceso ocurre porque las macromoléculas naturales como las proteínas, los polisacáridos, la celulosa y las gomas son generalmente degradables en los sistemas biológicos por hidrólisis seguida de oxidación. Por lo tanto, la formación de envases comestibles que contenían polisacáridos y emulsión de aceite esencial de hinojo fue satisfactoria.O processo de embalagem de alimentos é de imensa importância quando se trata de preservação de alimentos frescos ou processados. A maioria desses materiais são fabricados com plásticos sintéticos e sua eliminação representa um problema ambiental. Este estudo teve como objetivo preparar e caracterizar filmes compostos de biopolímeros, alginato de sódio (AS) e carboximetilcelulose (CMC), com adição de goma arábica e óleo essencial de erva doce. A análise de ângulo de contato mostra que os filmes são hidrofílicos. A superfície dos filmes apresentou estrutura firme, densa e coesa, porém com algumas rugosidades. Nas micrografias das amostras de filme contendo óleo essencial de erva doce nota-se estruturas parecidas com cristais sobre a matriz polimérica de CMC e AS. A umidade dos filmes foi, no geral, baixa (média de 14 %). Os menores percentuais de umidade apresentados foram para os filmes com de óleo essencial. Os filmes são biodegradáveis, esse processo ocorre, pois, as macromoléculas naturais, como proteínas, polissacarídeos, celulose e goma geralmente são degradáveis em sistemas biológicos pela hidrólise seguida de oxidação. Portanto, foi satisfatório a formação de embalagem comestível contendo polissacarídeos e emulsão de óleo essencial de erva-doce.Research, Society and Development2022-08-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3225710.33448/rsd-v11i10.32257Research, Society and Development; Vol. 11 No. 10; e351111032257Research, Society and Development; Vol. 11 Núm. 10; e351111032257Research, Society and Development; v. 11 n. 10; e3511110322572525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/32257/27864Copyright (c) 2022 Bruna dos Santos; Fabíola Medeiros da Costa; Thais Fátima Rodrigues; Vanusca Dalosto Jahno; Fauze Ahmad Aouada; Marcia Regina de Moura Aouadahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSantos, Bruna dos Costa, Fabíola Medeiros da Rodrigues, Thais Fátima Jahno, Vanusca DalostoAouada, Fauze AhmadAouada, Marcia Regina de Moura2022-08-12T22:23:03Zoai:ojs.pkp.sfu.ca:article/32257Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:48:18.918200Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
