The results showed that 103 signal peaks were detected in these rice varieties, and 91 volatile flavour substances were identified. Amongst them, 28 aldehydes (28.89~31.17%), 24 alcohols (34.85~40.52%), 14 ketones (12.26~14.74%), 12 esters (2.30~4.15%), 5 acids (7.80~10.85%), 3 furans (0.30~0.68%), 3 terpenes (0.34~0.64%), and 2 species of ethers (0.80~1.78%) were detected. SIMCA14.1 was used to perform principal component analysis (PCA) and orthogonal partial least squares discriminant analysis, and some potential character markers (VIP &gt; 1) were further screened out of the 91 flavour substances identified based on the variable important projections, including ethanol, 1-hexanol, hexanal, heptanal, nonanal, (E)-2-heptenal, octanal, trans-2-octenal, pentanal, acetone, 6-methyl-5-hepten-2-one, ethyl acetate, propyl acetate, acetic acid, and dimethyl sulphide. Based on the established fingerprint information, combined with principal component analysis and orthogonal partial least squares discriminant analysis, different rice varieties were also effectively classified, and the results of this study provide data references for the improvement in aromatic rice varieties.<\/jats:p>","DOI":"10.3390\/molecules28227566","type":"journal-article","created":{"date-parts":[[2023,11,13]],"date-time":"2023-11-13T08:44:27Z","timestamp":1699865067000},"page":"7566","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Analysis of the Differences in Volatile Organic Compounds in Different Rice Varieties Based on GC-IMS Technology Combined with Multivariate Statistical Modelling"],"prefix":"10.3390","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-8439-6934","authenticated-orcid":false,"given":"Jin","family":"Chen","sequence":"first","affiliation":[{"name":"Rice Research Institute, Yunnan Agricultural University, Kunming 650201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Liu","sequence":"additional","affiliation":[{"name":"Rice Research Institute, Yunnan Agricultural University, Kunming 650201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mi","family":"Yang","sequence":"additional","affiliation":[{"name":"Rice Research Institute, Yunnan Agricultural University, Kunming 650201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinmin","family":"Shi","sequence":"additional","affiliation":[{"name":"Lincang Seed Management Station, Lincang 677000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuqin","family":"Mei","sequence":"additional","affiliation":[{"name":"Lincang Seed Management Station, Lincang 677000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan","family":"Li","sequence":"additional","affiliation":[{"name":"Rice Research Institute, Yunnan Agricultural University, Kunming 650201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chunqi","family":"Yang","sequence":"additional","affiliation":[{"name":"Rice Research Institute, Yunnan Agricultural University, Kunming 650201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shihuang","family":"Pu","sequence":"additional","affiliation":[{"name":"Rice Research Institute, Yunnan Agricultural University, Kunming 650201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiancheng","family":"Wen","sequence":"additional","affiliation":[{"name":"Rice Research Institute, Yunnan Agricultural University, Kunming 650201, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"100271","DOI":"10.1016\/j.xplc.2021.100271","article-title":"Post-genomics revolution in the design of premium quality rice in a high-yielding background to meet consumer demands in the 21st century","volume":"3","author":"Sreenivasulu","year":"2022","journal-title":"Plant Commun."},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Gondal, T.A., Keast, R.S.J., Shellie, R.A., Jadhav, S.R., Gamlath, S., Mohebbi, M., and Liem, D.G.
