The best conditions for the production of capsules and fibers were obtained by varying the polymer concentration and resting time of the polymer solution. The best conditions were used for the encapsulation of curcumin. The curcumin-loaded capsules and fibers had an average diameter of 1373\u00a0nm to 1787\u00a0nm and 108\u00a0nm to 142\u00a0nm, respectively, and had a high curcumin loading capacity with values ranging from 79.01\u00a0% to 97.09\u00a0%. Curcumin encapsulated in starch capsules and fibers showed higher thermal stability at 180\u00a0\u00b0C for 2\u00a0h compared to unencapsulated curcumin. The antioxidant activity of starch fibers containing 1\u00a0% of curcumin had the greatest ability to inhibit the ABTS radical (45\u00a0% inhibition). These materials are promising for use in food or active packaging.<\/h3>\n<\/div>\n<p><a href=\"https:\/\/doi.org\/10.1016\/j.foodres.2022.112111\">https:\/\/doi.org\/10.1016\/j.foodres.2022.112111<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Juliani Buchveitz Pires, Laura Martins Fonseca, Tatiane J\u00e9ssica Siebeneichler, Rosane Lopes Crizel, Felipe Nardo dos Santos, Helen Cristina dos Santos Hackbart, Dianini H\u00fcttner Kringel, Adriana Dillenburg Meinhart, Elessandra da Rosa Zavareze, Alvaro Renato Guerra Dias Abstract The aim of this work was to encapsulate curcumin at different concentrations in capsules and fibers of native potato&#8230; <\/p>\n<div class=\"link-more\"><a href=\"https:\/\/wp.ufpel.edu.br\/bionano\/producao-cientifica\/2022-2\/curcumin-encapsulation-in-capsules-and-fibers-of-potato-starch-by-electrospraying-and-electrospinning-thermal-resistance-and-antioxidant-activity\/\">Leia mais<\/a><\/div>\n","protected":false},"author":1158,"featured_media":0,"parent":451,"menu_order":7,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-543","page","type-page","status-publish","hentry"],"publishpress_future_action":{"enabled":false,"date":"2026-04-21 20:23:30","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\/543","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=543"}],"version-history":[{"count":1,"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/pages\/543\/revisions"}],"predecessor-version":[{"id":548,"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/pages\/543\/revisions\/548"}],"up":[{"embeddable":true,"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/pages\/451"}],"wp:attachment":[{"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/media?parent=543"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
