This study conducted a comprehensive investigation into the volatile components of FFAPET using advanced analytical techniques, including GC-O-MS, GC-MS\/MS, aroma recombination, and omission tests. Compared with traditional stale aroma Pu-erh tea, FFAPET exhibited higher levels of alcohols and alkenes. Through GC-O-MS combined with OAV analysis, 10 key active-aroma compounds were identified in representative FFAPET samples. These compounds included (E, E)-2,4-heptadienal, phenylethyl alcohol, geraniol, (E, Z)-2,6-nonadienal, (Z)-4-heptenal, 2-phenethyl acetate, 2,2,6-trimethylcyclohexanone, D-limonene, \u03b2-ionone, and linalool, all of which made significant contributions to the development of the characteristic floral\u2013fruity aroma profile. Tests involving aroma recombination and omission further confirmed that seven of these odorants played essential roles in defining the overall aroma of FFAPET. These findings offer valuable theoretical insights for the enhancement and regulation of Pu-erh tea flavor, particularly for the optimization of the floral\u2013fruity aroma characteristics.<\/jats:p>","DOI":"10.3390\/foods14183223","type":"journal-article","created":{"date-parts":[[2025,9,17]],"date-time":"2025-09-17T11:00:00Z","timestamp":1758106800000},"page":"3223","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Unraveling the Key Odorants in Floral-Fruity Aroma Pu-Erh Tea via GC-O-MS, GC-MS\/MS, Aroma Recombination, and Omission Tests"],"prefix":"10.3390","volume":"14","author":[{"given":"Xianxiu","family":"Zhou","sequence":"first","affiliation":[{"name":"College of Tea Science, Yunnan Agricultural University, Kunming 650201, China"},{"name":"State Key Laboratory of Tea Plant Germplasm Innovation and Resource Utilization, Tea Research Institute, Chinese Academy of Agricultural Sciences, Hangzhou 310008, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiajing","family":"Hu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Tea Plant Germplasm Innovation and Resource Utilization, Tea Research Institute, Chinese Academy of Agricultural Sciences, Hangzhou 310008, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongchun","family":"Cui","sequence":"additional","affiliation":[{"name":"Tea Research Institute, Hangzhou Academy of Agriculture, Hangzhou 310024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiahao","family":"Tang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Tea Plant Germplasm Innovation and Resource Utilization, Tea Research Institute, Chinese Academy of Agricultural Sciences, Hangzhou 310008, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongwen","family":"Jiang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Tea Plant Germplasm Innovation and Resource Utilization, Tea Research Institute, Chinese Academy of Agricultural Sciences, Hangzhou 310008, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haibo","family":"Yuan","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Tea Plant Germplasm Innovation and Resource Utilization, Tea Research Institute, Chinese Academy of Agricultural Sciences, Hangzhou 310008, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiahua","family":"Li","sequence":"additional","affiliation":[{"name":"College of Tea Science, Yunnan Agricultural University, Kunming 650201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8793-9157","authenticated-orcid":false,"given":"Yanqin","family":"Yang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Tea Plant Germplasm Innovation and Resource Utilization, Tea Research Institute, Chinese Academy of Agricultural Sciences, Hangzhou 310008, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"132126","DOI":"10.1016\/j.foodchem.2022.132126","article-title":"Chemical profile of a novel ripened Pu-erh tea and its metabolic conversion during pile fermentation","volume":"378","author":"Li","year":"2022","journal-title":"Food Chem."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"100693","DOI":"10.1016\/j.fochx.2023.100693","article-title":"Characterization of volatile metabolites in Pu-erh teas with different storage years by combining GC-E-Nose, GC\u2013MS, and GC-IMS","volume":"18","author":"Rong","year":"2023","journal-title":"Food Chem.
