Water susceptibility and mechanical properties of thermoplastic starch-pectin blends reactively extruded with edible citric acid

Pectin and starch are edible, non-toxic, biodegradable and obtained from renewable sources. Also have the benefit to be easily cross-linked producing hydrogels. Reactive extrusion with edible citric acid and cross linking interactions was evaluated on extruded thermoplastic in natura and cationic st...

Reactive extrusion with edible citric acid and cross linking interactions was evaluated on extruded thermoplastic in natura and cationic starch-pectin blends. Materials water susceptibility and mechanical properties were characterised. Reactive extrusion decreased (up to 75% in natura starch) mechanical properties. Also have decreased (up to 32.4%) both starch polymers water absorption, indicating the possibility of increasing materials water barrier properties but had the opposite effect on the pectin-TPS material, probably related to a cationic-anionic cross linking, resulting in a hydrogel polymer. Reactive extrusion also have negatively affected mechanical properties of both starch polymers, however increased pectin-TPS blends stress and strain at rupture.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Mountain Equipment Co-opFederal University of Sao Carlos-UFSCar, Avenida General Carneiro, 1101Faculdade de Ciências Agronômicas-FCA Universidade Estadual Paulista Júlio de Mesquita Filho-UNESP, Avenida Marechal Floriano Peixoto, 240Department of Materials Engineering University of Sao Paulo-USP, Rua Episcopal, 1457Faculdade de Ciências Agronômicas-FCA Universidade Estadual Paulista Júlio de Mesquita Filho-UNESP, Avenida Marechal Floriano Peixoto, 240CNPq: 407044/2013-2CAPES: PNPD 02880/09-1FAPESP: JP 2007/08394-7Universidade Federal de São Carlos (UFSCar)Universidade Estadual Paulista (Unesp)Universidade de São Paulo (USP)2018-12-11T16:41:50Z2018-12-11T16:41:50Z2016-01-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article138-142application/pdfhttp://dx.doi.org/10.1590/1980-5373-MR-2015-0215Materials Research, v. 19, n. 1, p. 138-142, 2016.1516-1439http://hdl.handle.net/11449/16857010.1590/1980-5373-MR-2015-0215S1516-143920160001001382-s2.0-84963632313S1516-14392016000100138.pdf60572086540735590000-0003-3599-6103Scopusreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPengMaterials Research0,398info:eu-repo/semantics/openAccessDa Roz, Alessandra LuziaVeiga-Santos, Pricila [UNESP]Ferreira, Adriane MedeirosAntunes, Thais Cristina RibeiroDe Lima Leite, FabioYamaji, Fabio MinoruDe Carvalho, Antonio Jose Felix2025-08-29T05:56:21Zoai:repositorio.unesp.br:11449/168570Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestrepositoriounesp@unesp.bropendoar:29462025-08-29T05:56:21Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false
