In this way, their composition, organoleptic profile, and toxicity must be assessed. This work focuses on studying the volatile organic compounds (VOCs) emitted by three edible seaweeds, Grateloupia turuturu, Codium\u00a0tomentosum, and Bifurcaria\u00a0bifurcata, with the aim of deepening the knowledge regarding their organoleptic profiles. Nine samples of each seaweed were prepared in glass vials, and the emitted headspace was analyzed, for the first time, with a gas chromatography\u2014ion mobility spectrometry device, a highly sensitive technology. By statistically processing the collected data through PCA, it was possible to accurately differentiate the characteristic patterns of the three seaweeds with a total explained variance of 98%. If the data were pre-processed through PLS Regression, the total explained variance increased to 99.36%. The identification of 13 VOCs was accomplished through a developed database of compounds. These outstanding values in addition to the identification of the main emissions of VOCs and the utilization of a never-before-used technology prove the capacity of GC-IMS to differentiate edible seaweeds based solely on their volatile emissions, increase the knowledge regarding their organoleptic profiles, and provide an important step forward in the inclusion of these highly nutritional ingredients in the human diet.<\/jats:p>","DOI":"10.3390\/metabo13060713","type":"journal-article","created":{"date-parts":[[2023,6,1]],"date-time":"2023-06-01T02:39:47Z","timestamp":1685587187000},"page":"713","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Differentiation of the Organoleptic Volatile Organic Compound Profile of Three Edible Seaweeds"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7008-3401","authenticated-orcid":false,"given":"Pedro Catal\u00e3o","family":"Moura","sequence":"first","affiliation":[{"name":"Laboratory for Instrumentation, Biomedical Engineering and Radiation Physics (LIBPhys\u2014UNL), Department of Physics, NOVA School of Science and Technology, NOVA University of Lisbon, Campus FCT-UNL, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9312-5261","authenticated-orcid":false,"given":"Jorge Manuel","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Laboratory for Instrumentation, Biomedical Engineering and Radiation Physics (LIBPhys\u2014UNL), Department of Physics, NOVA School of Science and Technology, NOVA University of Lisbon, Campus FCT-UNL, 2829-516 Caparica, Portugal"},{"name":"NMT, S.
