The objective of this study was to isolate and characterize cellulose from Butia fruits and simultaneously produce cellulose nanofibers and cellulose acetate from the isolated cellulose. Cellulose extraction was performed using a combination of alkaline and bleaching treatments, while the production of cellulose nanofibers and cellulose acetate was achieved through acid hydrolysis and acetylation, respectively. The materials were characterized by their chemical composition, size distribution, zeta potential, morphology, relative crystallinity (XRD), functional groups (FTIR), molecular structure (NMR), and thermal stability (TGA). The Butia crude fibers presented 49.4 % cellulose, 4.5\u00a0% hemicellulose, 25.4\u00a0% lignin, and 1.3\u00a0% ash. The cellulose nanofibers presented an average diameter ranging from 13.7 to 93.1\u00a0nm and exhibited a high degree of crystallinity (63.3\u00a0%). FTIR, XRD,\u00a0<sup>13<\/sup>C, and\u00a0<sup>1<\/sup>H NMR analyses confirmed that the isolation processes effectively removed amorphous regions from the cellulose nanofibers and confirmed the cellulose acetylation process. As demonstrated, cellulosic materials derived from Butia fruit exhibit promise for various applications, including their potential use as reinforcing agents in polymer matrices, due to their high extraction yield, thermal properties, and crystallinity.<\/h3>\n<p><a href=\"https:\/\/doi.org\/10.1016\/j.ijbiomac.2024.136151\">https:\/\/doi.org\/10.1016\/j.ijbiomac.2024.136151<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cellulose, cellulose nanofibers, and cellulose acetate from Butia fruits (Butia odorata): Chemical, morphological, structural, and thermal properties Bruna da Fonseca Antunes; Luiza Ribeiro Santana; Raquel Moreira Oliveira; Alaor Val\u00e9rio Filho; Neftali Lenin Villarreal Carreno; Silvana Ines Wolke; Renata da Silva; Andr\u00e9 Ricardo Fajardo; Alvaro Renato Guerra Dias; Elessandra da Rosa Zavareze Cellulose possesses numerous advantageous&#8230; <\/p>\n<div class=\"link-more\"><a href=\"https:\/\/wp.ufpel.edu.br\/bionano\/producao-cientifica\/2024-2\/cellulose-cellulose-nanofibers-and-cellulose-acetate-from-butia-fruits-butia-odorata-chemical-morphological-structural-and-thermal-properties\/\">Leia mais<\/a><\/div>\n","protected":false},"author":1158,"featured_media":0,"parent":628,"menu_order":16,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-824","page","type-page","status-publish","hentry"],"publishpress_future_action":{"enabled":false,"date":"2026-04-22 01:11:44","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\/824","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=824"}],"version-history":[{"count":1,"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/pages\/824\/revisions"}],"predecessor-version":[{"id":825,"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/pages\/824\/revisions\/825"}],"up":[{"embeddable":true,"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/pages\/628"}],"wp:attachment":[{"href":"https:\/\/wp.ufpel.edu.br\/bionano\/wp-json\/wp\/v2\/media?parent=824"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
