A total of 59 volatile compounds were identified by using the optimized method, including 28 ethers, 15 aldehydes, 6 alcohols, 5 ketones, 2 hydrocarbons, 1 ester, and 2 phenols. Ethers are the most abundant, especially dimethyl trisulfide (10,623.30 \u03bcg\/kg). By calculating the odor activity values (OAVs), 11 volatile compounds were identified as the major aroma-active compounds of Chinese chive. From the analysis of the composition of Chinese chive aroma, the \u201cgarlic and onion\u201d odor (OAV = 2361.09) showed an absolute predominance over the other 5 categories of aroma. The results of this study elucidated the main sources of Chinese chive aroma from a chemical point of view and provided the theoretical basis for improving the flavor quality of Chinese chive.<\/jats:p>","DOI":"10.3390\/molecules27082425","type":"journal-article","created":{"date-parts":[[2022,4,9]],"date-time":"2022-04-09T05:13:08Z","timestamp":1649481188000},"page":"2425","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Optimization of Headspace Solid-Phase Micro-Extraction Conditions (HS-SPME) and Identification of Major Volatile Aroma-Active Compounds in Chinese Chive (Allium tuberosum Rottler)"],"prefix":"10.3390","volume":"27","author":[{"given":"Bojie","family":"Xie","sequence":"first","affiliation":[{"name":"College of Horticulture, Gansu Agricultural University, Lanzhou 730070, China"},{"name":"State Key Laboratory of Aridland Crop Science, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qian","family":"Wu","sequence":"additional","affiliation":[{"name":"College of Horticulture, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shouhui","family":"Wei","sequence":"additional","affiliation":[{"name":"College of Horticulture, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haiyan","family":"Li","sequence":"additional","affiliation":[{"name":"College of Water Conservancy and Hydropower Engineering, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinmei","family":"Wei","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Aridland Crop Science, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Medhia","family":"Hanif","sequence":"additional","affiliation":[{"name":"College of Horticulture, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ju","family":"Li","sequence":"additional","affiliation":[{"name":"College of Horticulture, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zeci","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Horticulture, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuemei","family":"Xiao","sequence":"additional","affiliation":[{"name":"College of Horticulture, Gansu Agricultural University, Lanzhou 730070, China"},{"name":"State Key Laboratory of Aridland Crop Science, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jihua","family":"Yu","sequence":"additional","affiliation":[{"name":"College of Horticulture, Gansu Agricultural University, Lanzhou 730070, China"},{"name":"State Key Laboratory of Aridland Crop Science, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Cecchi, L., Ieri, F., Vignolini, P., Mulinacci, N., and Romani, A.
