GC-MS single ion monitoring cromatogram and 3 zoomed chromatograms of a presentative exhaled breath sample (350 mL) spiked with internal standard (0.11 μg/μL acetone-d6) and extracted onto SPME fiber (75 μm carboxen-polydimethylsiloxane). Chromatogram peaks of compounds with characteristic ion for each compound (in brackets): (1) acetone (58) and acetone-d6 (64), (2) 2-propanol (45), (3) ethanol (46), (4) diacetyl (86), (5) 1-propanol (59), (6) 1-butanol (56), (7) acetoin (88), (8) acetic acid (60), (9) propionic acid (74), (10) butyric acid (60), (11) 2-methyl butyric acid (74) and isovaleric acid (60), (12) valeric acid (60), (13) hexanoic acid (60), and (14) phenol (94).

Postprandial changes in the signals of exhaled breath VOCs after a week of HFD (gray columns) and LFD (white columns) in 7 healthy men in a crossover design. Exhaled VOCs were analyzed in fasting state (0) and postprandially 30, 60, and 120 minutes after the test meal. Means are presented as columns and ± SD as error bars. *The significance of difference, P < .10 between diets analyzed with Wilcoxon test.
