This study aimed to\u00a0extract\u00a0starch from avocado seeds and its use as wall material to encapsulate ginger essential oil (GEO), at different concentrations. The fibers were produced by electrospinning and evaluated by morphology, size, infrared spectra, thermogravimetric properties, contact angle, loading capacity, and\u00a0antibacterial activity. The major compounds in GEO were \u03b1-zingiberene, \u03b2-sesquiphellandrene, \u03b1-farnesene, and \u03b1-curcumene. The starch-GEO fibers presented a higher diameter (\u223c553\u00a0nm) than those without GEO (345\u00a0nm). Encapsulation of GEO in starch fibers increased their thermal degradation temperatures from 165.8\u00a0\u00b0C (free GEO) to 257.6\u00a0\u00b0C (40\u00a0% GEO fibers). The starch-GEO fibers presented characteristic bands of their constituents by infrared spectra. Loading capacity ranged from 44 to 54\u00a0%. The fibers showed hydrophilic character, with a contact angle of &lt;90\u00b0. Free GEO and the fibers with 50\u00a0% of GEO displayed\u00a0antibacterial activity\u00a0against\u00a0<em>Escherichia coli<\/em>, proving the\u00a0bioactivity\u00a0of the starch-GEO fibers and its possible applicability for food packaging. Avocado seed starch showed to be a great wall material for GEO encapsulation.<\/h3>\n<p><a href=\"https:\/\/doi.org\/10.1016\/j.ijbiomac.2023.127617\">https:\/\/doi.org\/10.1016\/j.ijbiomac.2023.127617<\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Starch extraction from avocado by-product and its use for encapsulation of ginger essential oil by electrospinning Juliani Buchveitz Pires, Felipe Nardo dos Santos, Elder Pacheco da Cruz, Laura Martins Fonseca, Tatiane J\u00e9ssica Siebeneichler, Graciele Saraiva Lemos, Eliezer Avila Gandra, Elessandra da Rosa Zavareze, Alvaro Renato Guerra Dias Abstract Starches from alternative sources, such as avocado&#8230; <\/p>\n<div class=\"link-more\"><a href=\"https:\/\/wp.ufpel.edu.br\/bionano\/producao-cientifica\/2023-2\/starch-extraction-from-avocado-by-product-and-its-use-for-encapsulation-of-ginger-essential-oil-by-electrospinning\/\">Leia mais<\/a><\/div>\n","protected":false},"author":1158,"featured_media":0,"parent":545,"menu_order":11,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-668","page","type-page","status-publish","hentry"],"publishpress_future_action":{"enabled":false,"date":"2026-04-21 21:38:50","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\/668","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=668"}],"version-history":[{"count":2,"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/pages\/668\/revisions"}],"predecessor-version":[{"id":671,"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/pages\/668\/revisions\/671"}],"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=668"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
