In this study, volatile changes during storage were characterized using gas chromatography\u2013ion mobility spectrometry (GC\u2013IMS), and a rapid monitoring method based on near-infrared spectroscopy (NIRS) was developed. GC\u2013IMS identified 74 volatile compounds, with aldehydes and ketones increasing significantly during storage, indicating progressive lipid oxidation. Key markers, including 2-furaldehyde, 1-pentanoic acid, and \u03b3-caprolactone, were identified as indicators of quality deterioration. Based on these markers, composite flavor and storage deterioration indices were constructed and used as reference parameters for NIRS calibration. Partial least squares regression models developed in the 1300\u20132500 nm region showed strong predictive performance for these composite indices, with R2p &gt; 0.93 and RPD &gt; 4.0. The long-wave NIR region exhibited superior sensitivity to oxidation-related spectral changes. These results demonstrate that NIRS combined with GC\u2013IMS analysis provides an effective, chemically interpretable approach for rapid, non-destructive monitoring of storage quality in processed coix seeds.<\/jats:p>","DOI":"10.3390\/foods15091542","type":"journal-article","created":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T09:46:11Z","timestamp":1777455971000},"page":"1542","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Rapid Monitoring of Storage Deterioration in Processed Coix Seeds Using Near-Infrared Spectroscopy Guided by GC\u2013IMS"],"prefix":"10.3390","volume":"15","author":[{"given":"Jiangshan","family":"Zhang","sequence":"first","affiliation":[{"name":"Key Laboratory of Modern Preparation of Chinese Medicine, Ministry of Education, National Key Laboratory of Classic Formula and Modern Traditional Chinese Medicine Creation, Jiangxi University of Chinese Medicine, Nanchang 330004, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-5987-0667","authenticated-orcid":false,"given":"Tongtong","family":"Wu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Optoelectronic Materials and Technologies, School of Physics, Nanchang Research Institute, Sun Yat-sen University, Guangzhou 510275, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6673-3221","authenticated-orcid":false,"given":"Xiangyang","family":"Yu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Optoelectronic Materials and Technologies, School of Physics, Nanchang Research Institute, Sun Yat-sen University, Guangzhou 510275, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming","family":"Yang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Modern Preparation of Chinese Medicine, Ministry of Education, National Key Laboratory of Classic Formula and Modern Traditional Chinese Medicine Creation, Jiangxi University of Chinese Medicine, Nanchang 330004, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-3816-5827","authenticated-orcid":false,"given":"Penghui","family":"Zeng","sequence":"additional","affiliation":[{"name":"Jiangxi Jingde Traditional Chinese Medicine Co., Ltd., Jingdezhen 333000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaolin","family":"Xiao","sequence":"additional","affiliation":[{"name":"Jiangxi Jingde Traditional Chinese Medicine Co., Ltd., Jingdezhen 333000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yushan","family":"Li","sequence":"additional","affiliation":[{"name":"Jiangxi Jingde Traditional Chinese Medicine Co., Ltd., Jingdezhen 333000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"921","DOI":"10.1080\/87559129.2021.1892129","article-title":"Coix Seed: A Review of Its Physicochemical Composition, Bioactivity, Processing, Application, Functionality, and Safety Aspects","volume":"38","author":"Igbokwe","year":"2022","journal-title":"Food Rev.
