study aimed to investigate the content of major bioactive compounds and characterize the volatile and sensory profiles of Coffea canephora flowers and their infusions. Dried flowers from six selected genotypes of C. canephora trees and their infusions were analyzed for bioactive compounds using HPLC\u2013DAD, while volatile organic compounds (VOC) were analyzed using GC\u2013MS. Eight chlorogenic acids (CGA), seven phenolic acids, and the alkaloids caffeine and trigonelline were quantified in all methanolic flower extracts. Total CGA, phenolic acids, caffeine, and trigonelline contents in the methanolic extracts ranged between 342.8 and 1079.4 mg\/100 g, 27.1 and 41.0 mg\/100 g, 515.6 and 745.9 mg\/100 g, and 453.8 and 645.2 mg\/100 g, respectively. CGA, caffeine, and trigonelline were well extracted (84%, 91%, and 74%, respectively) when the flowers were infused in hot water. No free phenolic acids were identified in the infusions. Eighty-five VOC were identified in the flowers. Aldehydes, monoterpenes, esters, alcohols, monoterpene alcohols, acids, and ketones prevailed in order of the number of compounds. In the infusions, 38 VOC were accurately identified. Monoterpenes and monoterpene alcohols prevailed. In general, floral, jasmine and orange blossom, herbal, green coffee, woody, and sweet were the most cited sensory attributes for fragrance, aroma, and flavor. Considering the typically weak aroma of C. canephora seeds, the aroma and flavor of the flower\u2019s infusions were surprisingly strong and pleasant, showing great marketing potential.<\/jats:p>","DOI":"10.3390\/foods14060911","type":"journal-article","created":{"date-parts":[[2025,3,7]],"date-time":"2025-03-07T07:05:46Z","timestamp":1741331146000},"page":"911","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Major Bioactive Compounds, Volatile and Sensory Profiles of Coffea canephora Flowers and Infusions for Waste Management in Coffee Production"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5649-2003","authenticated-orcid":false,"given":"Juliana","family":"DePaula","sequence":"first","affiliation":[{"name":"Laborat\u00f3rio de Qu\u00edmica e Bioatividade de Alimentos & N\u00facleo de Pesquisa em Caf\u00e9 Professor Luiz Carlos Trugo-NuPeCaf\u00e9, Instituto de Nutri\u00e7\u00e3o Josu\u00e9 de Castro, Universidade Federal do Rio de Janeiro, Rio de Janeiro 21941-902, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4320-2318","authenticated-orcid":false,"given":"Sara C.","family":"Cunha","sequence":"additional","affiliation":[{"name":"LAQV\/REQUIMTE, Laborat\u00f3rio de Bromatologia e Hidrologia, Departamento de Ci\u00eancias Qu\u00edmicas, Faculdade de Farm\u00e1cia da Universidade do Porto, 4099-030 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8830-0846","authenticated-orcid":false,"given":"F\u00e1bio Luiz","family":"Partelli","sequence":"additional","affiliation":[{"name":"Departamento de Ci\u00eancias Agr\u00e1rias e Biol\u00f3gicas, Centro Universit\u00e1rio do Norte do Esp\u00edrito Santo, Universidade Federal do Esp\u00edrito Santo, S\u00e3o Mateus 29932-900, Esp\u00edrito Santo, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8565-2942","authenticated-orcid":false,"given":"Jos\u00e9 O.","family":"Fernandes","sequence":"additional","affiliation":[{"name":"LAQV\/REQUIMTE, Laborat\u00f3rio de Bromatologia e Hidrologia, Departamento de Ci\u00eancias Qu\u00edmicas, Faculdade de Farm\u00e1cia da Universidade do Porto, 4099-030 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7584-5564","authenticated-orcid":false,"given":"Adriana","family":"Farah","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Qu\u00edmica e Bioatividade de Alimentos & N\u00facleo de Pesquisa em Caf\u00e9 Professor Luiz Carlos Trugo-NuPeCaf\u00e9, Instituto de Nutri\u00e7\u00e3o Josu\u00e9 de Castro, Universidade Federal do Rio de Janeiro, Rio de Janeiro 21941-902, Brazil"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"283","DOI":"10.1016\/bs.abr.2024.04.005","article-title":"A climate change perspective on the selection, development, and management of Coffea canephora genotypes","volume":"114","author":"Salvador","year":"2025","journal-title":"Adv.
