The physicochemical properties of three selected aroma compounds, and capsaicin.

Compounds	Molecular Mass (Da)	Target Ion (m/z)	Signal variation (%CV#, n = 4)	Hydrophobicity (Log P##)	Volatility (VP##, 25 °C, mm Hg)	Air-water partitioning coefficient (Kaw##)
3-Methylbutanal	86	87	3%	1.23	51.60	6.49E−03
1-Octen-3-ol	128	111	4%	2.73	0.24	9.45E−04
Linalool	154	137	7%	3.38	0.08	1.73E−03
Capsaicin	305	NA	NA	4.0	1.32E −08	4.23E −12

^#CV% = 100 × Standard Deviation/Mean.

^##The value of Log P, vapour pressure (VP) and Kaw were estimated by EPI Suite™ v.4.1 software, U.S. Environmental Protection Agency.
