It reveals the coupling relationship between spatial heat transfer modes and release mechanisms. GC\u2010MS and GC\u2010MS\/MS were used for compound identification and quantification. GC\u2010MS employed a DB\u20105MS column in full\u2010scan mode. GC\u2010MS\/MS also used a DB\u20105MS column with MRM mode. A total of 16 key aromatic components from eight categories (acids, ketones, esters, phenols, alcohols, aldehydes, heterocyclics, and lactones) were analyzed. The results showed consistent high release levels for valeric acid, 3\u2010methylvaleric acid, and linalool. Central heating led to peak releases around 350\u00b0C, while circumferential heating showed a release trend peaking at 250\u00b0C. Kinetic analysis revealed different models, and activation energy analysis indicated varying release difficulties between the heating methods. The release mechanisms of different aromatic raw compounds were jointly analyzed using zero\u2010order, pseudo\u2010first\u2010order, and pseudo\u2010second\u2010order models. Under central heating, acids\/aldehydes followed the zero\u2010order model, while under circumferential heating, ketones\/esters\/phenols were more suited to the zero\u2010order model.<\/jats:p>","DOI":"10.1002\/jssc.70195","type":"journal-article","created":{"date-parts":[[2025,6,23]],"date-time":"2025-06-23T00:55:47Z","timestamp":1750640147000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Thermal
