In the simulation of\u00a0<i>in vitro<\/i>\u00a0biological digestion, the phenolic compounds release profile was also evaluated. The ultrafine fibers were produced by electrospinning, based on a polymeric solution composed of soluble potato starch (50% w\/v) and formic acid. Then, PCE was incorporated at various concentrations (0.5%, 1.0%, and 1.5%, w\/w, dry basis). The endothermic event of free PCE was not observed in the ultrafine fibers, which suggests its encapsulation. The RC decreased according to the increase in PCE concentration in the ultrafine fibers. The PCE resisted thermal treatments when encapsulated into the ultrafine fibers (100 and 180\u00b0C), and the ultrafine fibers with 1% PCE presented the highest amount of preserved phenolic compounds. Regarding antioxidant activity, the free PCE presented 85% of DPPH inhibition and the ultrafine fibers had 18% inhibition, not differing among the PCE concentrations (<i>p<\/i>\u00a0&lt;\u00a00.05). The free PCE and the ultrafine fibers with 0.5% PCE showed inhibitory effect against\u00a0<i>S. aureus<\/i>\u00a0and the ones with 1.5% PCE showed controlled release of phenolic compounds during the simulation of\u00a0<i>in vitro<\/i>\u00a0digestion. Starch ultrafine fibers showed potential to be applied in food industries due to their capacity of protecting phenolic compounds when submitted to high temperatures or gastrointestinal conditions. Nevertheless, their application depends on the end use of the product.<\/h3>\n<p><a href=\"https:\/\/doi.org\/10.1111\/1750-3841.15779\">https:\/\/doi.org\/10.1111\/1750-3841.15779<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Elder Pacheco da Cruz, Laura Martins Fonseca, Marjana Rad\u00fcnz, Francine Tavares da Silva, Eliezer Avila Gandra, Elessandra da Rosa Zavareze, Caroline Dellinghausen Borges Abstract This study aimed to produce soluble potato starch ultrafine fibers for the encapsulation of\u00a0pinh\u00e3o\u00a0coat extract (PCE), evaluating their relative crystallinity (RC), thermal stability, antioxidant activity, antimicrobial activity against\u00a0Escherichia coli\u00a0and\u00a0Staphylococcus aureus, as&#8230; <\/p>\n<div class=\"link-more\"><a href=\"https:\/\/wp.ufpel.edu.br\/bionano\/producao-cientifica\/2021-2\/pinhao-coat-extract-encapsulated-in-starch-ultrafine-fibers-thermal-antioxidant-and-antimicrobial-properties-and-in-vitro-biological-digestion\/\">Leia mais<\/a><\/div>\n","protected":false},"author":1158,"featured_media":0,"parent":373,"menu_order":7,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-401","page","type-page","status-publish","hentry"],"publishpress_future_action":{"enabled":false,"date":"2026-05-13 08:15:49","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\/401","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=401"}],"version-history":[{"count":1,"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/pages\/401\/revisions"}],"predecessor-version":[{"id":403,"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/pages\/401\/revisions\/403"}],"up":[{"embeddable":true,"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/pages\/373"}],"wp:attachment":[{"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/media?parent=401"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
