The aerogels were produced using germinated wheat starch (GWS), with and without PEO, and incorporating grape skin\u00a0extract\u00a0(GSE) at concentrations of 5 and 10\u00a0% (w\/w). The GSE was evaluated for total and individual phenolic compounds,\u00a0anthocyanins, and\u00a0antioxidant activity. The starch aerogels were characterized for morphology, density, porosity, functional groups by FT-IR, relative crystallinity and diffraction pattern, water absorption capacity,\u00a0antioxidant activity, and\u00a0<em>in vitro<\/em>\u00a0release profile of phenolic compounds in food simulant medium. The total phenolic compounds in GSE was 226.25\u00a0\u00b1\u00a00.01\u00a0mg equivalent of gallic acid\/g GSE. The aerogels showed low density and high porosity. All aerogels demonstrated high water absorption capacity (581.4 to 997.5\u00a0%). The antioxidant activity of the aerogels increased with increasing GSE concentration and the addition of PEO. The aerogels could release GSE gradually for up to 120\u00a0days in the hydrophilic simulant medium and 240\u00a0h for the hydrophobic medium. Starch-based aerogels with GSE showed potential to be applied as exudate absorbers with antioxidant activity to develop active food packaging.<\/h3>\n<p><a href=\"https:\/\/doi.org\/10.1016\/j.ijbiomac.2023.126108\">https:\/\/doi.org\/10.1016\/j.ijbiomac.2023.126108<\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Absorbent bioactive aerogels based on germinated wheat starch and grape skin extract Francine Tavares Silva, Laura Martins Fonseca, Graziella Pinheiro Bruni, Rosane Lopes Crizel, Elizangela Gon\u00e7alves Oliveira, Elessandra da Rosa Zavareze, Alvaro Renato Guerra Dias Abstract This study aimed to produce water-absorbent bioactive aerogels using biodegradable raw materials, wheat starch and poly ethylene oxide (PEO),&#8230; <\/p>\n<div class=\"link-more\"><a href=\"https:\/\/wp.ufpel.edu.br\/bionano\/producao-cientifica\/2023-2\/absorbent-bioactive-aerogels-based-on-germinated-wheat-starch-and-grape-skin-extract\/\">Leia mais<\/a><\/div>\n","protected":false},"author":1158,"featured_media":0,"parent":545,"menu_order":9,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-662","page","type-page","status-publish","hentry"],"publishpress_future_action":{"enabled":false,"date":"2026-04-26 14:39:14","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"","extraData":[]},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"_links":{"self":[{"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/pages\/662","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/users\/1158"}],"replies":[{"embeddable":true,"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/comments?post=662"}],"version-history":[{"count":1,"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/pages\/662\/revisions"}],"predecessor-version":[{"id":664,"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/pages\/662\/revisions\/664"}],"up":[{"embeddable":true,"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/pages\/545"}],"wp:attachment":[{"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/media?parent=662"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
