Resumo: The purpose of this study was to develop active films of low-density polyethylene incorporated with different concentrations of oregano essential oil (1, 2, 3, 4, 5 and 6% w / w). The production of the films was carried out in a modular mono screw extruder and the   antimicrobial activity was evaluated by the agar diffusion test. The films were analyzed for mechanical, optical and gaseous barrier properties to evaluate changes in the films due to the addition of an antimicrobial agent. As a result, it was found that the control film had a higher luminosity, compared to the others. The opacity was not affected. Saturation, however, had a tendency to transform more vivid colors, while the tone had a decrease tendency towards yellow. In terms of mechanical properties, elongation was not affected, Young's modulus decreased and tension increased. The CO2 permeability decreased. There were no inhibition halos around the films.

La producción de las películas se llevó a cabo en una extrusora monohusillo modular y la actividad antimicrobiana se evaluó mediante la prueba de difusión en agar. Las películas se analizaron en busca de propiedades mecánicas, ópticas y de barrera a los gases, para evaluar sus cambios debido a la adición de un agente antimicrobiano. Como resultado, se encontró que la película de control mostraba mayor brillo en comparación con las demás. La opacidad no se vio afectada. La saturación, sin embargo, tendió a cambiar a colores más vivos, mientras que el tono tendió a disminuir, hacia el amarillo. Para las propiedades mecánicas, el alargamiento no se vio afectado, el módulo de Young disminuyó y la tensión aumentó. La permeabilidad al CO2 ha disminuido. No hubo formación de un halo de inhibición alrededor de las películas.O objetivo deste estudo foi desenvolver filmes ativos de polietileno de baixa densidade incorporados com diferentes concentrações de óleo essencial de orégano (1, 2, 3, 4, 5 e 6% p/p). A produção dos filmes foi realizada em extrusora modular mono rosca e a atividade antimicrobiana avaliada pelo teste de difusão em ágar. Os filmes foram analisados ​​quanto às propriedades mecânicas, ópticas e de barreira gasosa, para avaliar suas alterações devido à adição de um agente antimicrobiano. Como resultado, constatou-se que o filme controle apresentou maior luminosidade, em relação aos demais. A opacidade não foi afetada. A saturação, no entanto, teve uma tendência a transformação em cores mais vívidas, enquanto a tonalidade tendeu a decrescer, em sentido a cor amarela. Para as propriedades mecânicas, a elongação não foi afetada, o módulo de Young diminuiu e a tensão aumentou. A permeabilidade ao CO2 decresceu. Não houve formação de halo de inibição ao redor dos filmes.Research, Society and Development2020-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/872210.33448/rsd-v9i10.8722Research, Society and Development; Vol. 9 No. 10; e3849108722Research, Society and Development; Vol. 9 Núm. 10; e3849108722Research, Society and Development; v. 9 n. 10; e38491087222525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/8722/7717Copyright (c) 2020 Lara Bueno Coelho; Robson Maia Geraldine; Miriam Fontes Araújo Silveira; Adriana Régia Marques de Souza; Maria Célia Lopes Torres; Maria Ássima Bittar Gonçalveshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCoelho, Lara Bueno Geraldine, Robson Maia Silveira, Miriam Fontes Araújo Souza, Adriana Régia Marques de Torres, Maria Célia Lopes Gonçalves, Maria Ássima Bittar 2020-10-31T12:03:23Zoai:ojs.pkp.sfu.ca:article/8722Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:31:08.347239Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
