Decolorization of a corn fiber arabinoxylan extract and formulation of biodegradable films for food packagingArabinoxylanBiodegradable filmsCorn fiberDecolorizationFood packagingChemical Engineering (miscellaneous)Process Chemistry and TechnologyFiltration and SeparationUID/AGR/04129/2020Corn fiber from the corn starch industry is a by-product produced in large quantity that is mainly used in animal feed formulations, though it is still rich in valuable components, such as arabinoxylans, with proven film-forming ability. During arabinoxylans’ recovery under alkaline extraction, a dark-colored biopolymer fraction is obtained. In this work, a purified arabinoxylan extract from corn fiber with an intense brownish color was decolorized using hydrogen peroxide as the decolorizing agent. Biodegradable films prepared by casting the decolorized extract exhibited a light-yellow color, considered more appealing, envisaging their application in food packaging. Films were prepared with glycerol as plasticizer and citric acid as cross-linker. Although the cross-linking reaction was not effective, films presented antioxidant activity, a water vapor permeability similar to that of non-decolorized films, and other polysaccharides’ and mechanical properties that enable their application as packaging materials of low-water-content food products.DQ - Departamento de QuímicaLAQV@REQUIMTERUNWeng, VerónicaBrazinha, CarlaCoelhoso, Isabel M.Alves, Vitor D.2021-09-08T00:19:02Z2021-04-282021-04-28T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10362/124148eng0076-6356PURE: 31970173https://doi.org/10.3390/membranes11050321info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-05-22T17:55:53Zoai:run.unl.pt:10362/124148Portal AgregadorONGhttps://www.rcaap.pt/oai/openairemluisa.alvim@gmail.comopendoar:71602024-05-22T17:55:53Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
