Its unique environment endows it with a strong chestnut- and seaweed-like aroma. This study sought to explore the volatile profiles of RZT and pinpoint its key odorants by employing stir bar sorptive extraction (SBSE) coupled with gas chromatography\u2013mass spectrometry (GC-MS), determining the odor activity value (OAV), and performing gas chromatography\u2013olfactometry (GC-O). A total of 112 volatiles were identified, and the major volatile compounds were esters (2035.25 \u03bcg\/kg), alcohols (1799.02 \u03bcg\/kg), alkanes (991.88 \u03bcg\/kg), and ketones (691.96 \u03bcg\/kg), comprising 74.91% of the total. A molecular aroma wheel was preliminarily established based on these key odorants. These insights might contribute to the scientific elucidation of the flavor chemical basis of RZT.<\/jats:p>","DOI":"10.3390\/foods14030458","type":"journal-article","created":{"date-parts":[[2025,1,31]],"date-time":"2025-01-31T04:05:47Z","timestamp":1738296347000},"page":"458","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Insight into the Volatile Profiles and Key Odorants of Rizhao Green Tea by Application of SBSE-GC-MS, OAVs and GC-O Analysis"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2243-6967","authenticated-orcid":false,"given":"Mengqi","family":"Wang","sequence":"first","affiliation":[{"name":"Tea Research Institute, Rizhao Academy of Agricultural Sciences, Rizhao 276800, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dapeng","family":"Song","sequence":"additional","affiliation":[{"name":"Tea Research Institute, Rizhao Academy of Agricultural Sciences, Rizhao 276800, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongxu","family":"Yin","sequence":"additional","affiliation":[{"name":"Rizhao Donggang District Agriculture and Rural Bureau, Rizhao 276800, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fengxiang","family":"Fang","sequence":"additional","affiliation":[{"name":"Tea Research Institute, Rizhao Academy of Agricultural Sciences, Rizhao 276800, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yali","family":"Shi","sequence":"additional","affiliation":[{"name":"Tea Research Institute, Shandong Academy of Agricultural Sciences, Jinan 250100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui","family":"Wang","sequence":"additional","affiliation":[{"name":"Tea Research Institute, Rizhao Academy of Agricultural Sciences, Rizhao 276800, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiyan","family":"Li","sequence":"additional","affiliation":[{"name":"Tea Research Institute, Rizhao Academy of Agricultural Sciences, Rizhao 276800, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kunpeng","family":"Wang","sequence":"additional","affiliation":[{"name":"Tea Research Institute, Rizhao Academy of Agricultural Sciences, Rizhao 276800, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1061-5100","authenticated-orcid":false,"given":"Yin","family":"Zhu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Biology, Genetics and Breeding of Special Economic Animals and Plants, Ministry of Agriculture and Rural Affairs, Tea Research Institute, Chinese Academy of Agricultural Sciences, Hangzhou 310008, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4644-4323","authenticated-orcid":false,"given":"Haipeng","family":"Lv","sequence":"additional","affiliation":[{"name":"Key Laboratory of Biology, Genetics and Breeding of Special Economic Animals and Plants, Ministry of Agriculture and Rural Affairs, Tea Research Institute, Chinese Academy of Agricultural Sciences, Hangzhou 310008, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shibo","family":"Ding","sequence":"additional","affiliation":[{"name":"Tea Research Institute, Rizhao Academy of Agricultural Sciences, Rizhao 276800, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"10582","DOI":"10.1021\/jf102415m","article-title":"Geographical and climatic dependencies of green tea (Camellia sinensis) metabolites: A 1H NMR-based metabolomics study","volume":"58","author":"Lee","year":"2010","journal-title":"J.
