摘要： Inspired by the emergence of natural deep eutectic solvents (DESs), we herein used thermogravimetry and pyrolysis-gas chromatography/mass spectrometry to probe the influence of six DESs (hydrogen bond acceptor = choline chloride, betaine, or L-proline; hydrogen bond donor = glycerol, 1,4-butanediol, or propylene glycol) on the release of volatiles from tobacco at 300 degrees C. DES treatment induced a 3.5-4.6% increase in second stage weight loss and promoted the release of 28 aroma constituents (furans, aldehydes, ketones, and organic acids). Treatment with choline chloride-glycerol-propylene glycol increased the relative contents of the released 5-hydroxymethylfurfural and megastigmatrienone by factors of 1.2 and 3.6, respectively, whereas treatment with L-proline-glycerol promoted the release of 2,3-dihydro-3,5-dihydroxy-6-methyl-(4H)-pyran-4-one. Therefore, DES treatment facilitated the release of volatiles from tobacco powder and was inferred to be promising for the development of novel cigarette constituents.
