A total of 19 low molecule fraction compounds and 26 volatile fraction compounds were identified as the common peaks. Chemometrics were used to screen the characteristic compounds of the five varieties of Chrysanthemums. E-tongue and E-nose were used to distinguish the taste and odor of the five varieties of Chrysanthemum, respectively. The Hangju variety had the richest taste flavor and the weakest aroma, while the Huaiju variety had the strongest odor of pine, woody, floral, and fruity aroma. The study found that 3, 5-dicaffeoylquinic acid, 1, 5-dicaffeoylquinic acid, luteolin-7-\u03b2-D-glucoside, and 4, 5-dicaffeoylquinic acid were the principal taste flavor components based on Gray Relational Analysis (GRA) and Partial Least Squares Regression (PLSR). \u03b1-pinene, camphene, \u03b3-terpinene, camphor, etc. were identified as the principal volatile flavor components based on Spearman\u2019s rank correlation. The combination of chemometrics and intelligent sensory technology presents a potential technique for analyzing the flavor of Chrysanthemums and other food products.<\/jats:p>","DOI":"10.3390\/foods15183328","type":"journal-article","created":{"date-parts":[[2026,9,21]],"date-time":"2026-09-21T14:12:09Z","timestamp":1789999929000},"page":"3328","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparative Study on Taste and Odor Flavor Compounds of Chrysanthemums from Five Different Varieties Using UPLC-Q-TOF-MS, GC-MS, E-Tongue, E-Nose, and Chemometrics"],"prefix":"10.3390","volume":"15","author":[{"given":"Guizhou","family":"Hu","sequence":"first","affiliation":[{"name":"School of Traditional Chinese Pharmacy, China Pharmaceutical University, Nanjing 211198, China"},{"name":"School of Pharmacy, Bengbu Medical University, Bengbu 233030, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"software","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6634-0778","authenticated-orcid":false,"given":"Xinqi","family":"Li","sequence":"additional","affiliation":[{"name":"School of Traditional Chinese Pharmacy, China Pharmaceutical University, Nanjing 211198, China"},{"name":"Jiangsu Provincial Key Laboratory for Plant Taxonomy, Resource Conservation and Utilization, Institute of Botany, Jiangsu Province and Chinese Academy of Sciences (Nanjing Botanical Garden Memorial Sun Yat-Sen), Nanjing 210014, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"methodology","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"software","vocabulary":"credit"}]},{"given":"Geng","family":"Qin","sequence":"additional","affiliation":[{"name":"School of Traditional Chinese Pharmacy, China Pharmaceutical University, Nanjing 211198, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"software","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"}]},{"given":"Ailing","family":"Ben","sequence":"additional","affiliation":[{"name":"Nanjing Key Laboratory of Quality and Safety of Agricultural Products, College of Food Science, Nanjing XiaoZhuang University, Nanjing 211171, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"supervision","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"}]},{"given":"Jin","family":"Qi","sequence":"additional","affiliation":[{"name":"School of Traditional Chinese Pharmacy, China Pharmaceutical University, Nanjing 211198, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"32282","DOI":"10.1021\/acsomega.5c04315","article-title":"Quality grading of \u201cFubaiju\u201d based on inflorescence diameter and content of polyphenolic substances","volume":"10","author":"Yang","year":"2025","journal-title":"ACS Omega"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"112186","DOI":"10.1016\/j.foodres.2022.112186","article-title":"UHPLC-QTOF-MS-based untargeted metabolomics and mineral element analysis insight into the geographical differences of Chrysanthemum morifolium Ramat. cv. \u201cHangbaiju\u201d from different origins","volume":"163","author":"Long","year":"2023","journal-title":"Food Res.
