Decolorization of a corn fiber Arabinoxylan extract and formulation of biodegradable films for food packagingcorn fiberarabinoxylandecolorizationbiodegradable filmsfood packagingCommunicationCorn 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 productsMDPIRepositório da Universidade de LisboaWeng, VerónicaBrazinha, CarlaCoelhoso, Isabel M.Delgado Alves, Vitor2021-06-02T15:07:32Z20212021-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.5/21421engWeng, V.; Brazinha, C.; Coelhoso, I.M.; Alves, V.D.
