Resumo: Chitosan is a biopolymer with wide application in the cosmetic, textile, food and agriculture areas. In this work chitosan nanoparticles (CNP) was produced by ionic gelation and used as coating in starch (TPS) and poly(lactic acid) (PLA) sheets produced by thermoplastic extrusion. In the CNP the average diameter, the morphology by transmission electronic microscopy and the antimicrobial activity against the microorganism Salmonella typhimurium, Staphylococcus aureus, Penicillium expansum and Aspergillus ochraceus were determined. In the TPS/PLA sheets coated with CNP the mechanical properties and water vapor permeability (WVP) were determined. The CNP were successfully produced by ionic gelation method, the average diameter was 146.9 nm, the polydispersity index was 0.281 and showed spherical shape. The CNP did not show antimicrobial activity against the microorganism studied. Furthermore, their use as a coating on TPS/PLA sheets did not alter the mechanical and water vapor barrier properties and thickness.

En este trabajo, se sintetizaron nanopartículas de quitosano (NPQ) mediante gelificación iónica y se utilizaron para recubrir laminados a base de mezclas de almidón y poli (ácido láctico) (TPS/PLA) producidos por extrusión termoplástica. En las NPQ se determinó el diámetro medio, la morfología por microscopía electrónica de transmisión y la actividad antimicrobiana frente a los microorganismos Salmonella typhimurium, Staphylococcus aureus, Penicillium expansum y Aspergillus ochraceus. En laminados de TPS/PLA cubiertos con NPQ, se determinaron las propiedades mecánicas y la permeabilidad al vapor de agua. Los NPQ se produjeron con éxito mediante el método de gelificación iónica, el diámetro promedio fue de 146,9 nm, el índice de polidispersión fue de 0,281 y presentó morfología esférica. Los NPQ no mostraron actividad antimicrobiana frente a los microorganismos estudiados. Sin embargo, su aplicación como recubrimiento sobre laminados extruidos de TPS/PLA no modificó las propiedades mecánicas y la barrera al vapor de agua y el espesor.A quitosana é um biopolímero com ampla aplicação na área cosmética, têxtil, alimentícia e na agricultura. Neste trabalho nanopartículas de quitosana (NPQ) foram sintetizadas por gelificação iônica e foram utilizadas no recobrimento de laminados a base de blenda de amido e poli(ácido lático) (TPS/PLA) produzidas por extrusão termoplástica. Nas NPQ determinou-se o diâmetro médio, a morfologia por microscopia eletrônica de transmissão e a atividade antimicrobiana frente aos microrganismos Salmonella typhimurium, Staphylococcus aureus, Penicillium expansum e Aspergillus ochraceus. Nos laminados de TPS/PLA recobertos com NPQ foram determinadas as propriedades mecânicas e a permeabilidade ao vapor de água. As NPQ foram produzidas com êxito através do método de gelificação iônica, o diâmetro médio foi de 146,9 nm, o índice de polidisperção foi de 0,281 e apresentaram morfologia esférica. As NPQ não apresentaram atividade antimicrobiana frente aos microrganismos estudados. Entretanto, sua aplicação como recobrimento em laminados extrusados de TPS/PLA não alteraram as propriedades mecânicas e de barreira ao vapor de água e a espessura.Research, Society and Development2020-08-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/769410.33448/rsd-v9i9.7694Research, Society and Development; Vol. 9 No. 9; e505997694Research, Society and Development; Vol. 9 Núm. 9; e505997694Research, Society and Development; v. 9 n. 9; e5059976942525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/7694/6685Copyright (c) 2020 Marcella Vitoria Galindo; Isabela dos Santos Paglione; Alexandre Rodrigo Coelho; Fernanda Vitória Leimann; Marianne Ayumi Shiraihttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGalindo, Marcella VitoriaPaglione, Isabela dos SantosCoelho, Alexandre RodrigoLeimann, Fernanda VitóriaShirai, Marianne Ayumi2020-09-18T01:42:11Zoai:ojs.pkp.sfu.ca:article/7694Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:30:20.564256Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
