The volatile components of bergamot (Citrus bergamia Risso) essential oil produced in Reggio Calabria in Italy were investigated using GC, GC-MS and gas chromatography-olfactometry (GC-O). Fifty-five compounds in the oil were identified by GC and GC-MS. The major compounds were limonene (37.2%), linalyl acetate (30.1%), linalool (8.8%), γ γ γ γ γ -terpinene (6.8%) and β β β β β-pinene (6.2%). In sensory analysis, odour description and flavour dilution (FD) factors of each component were evaluated by GC-sniffing and aroma extraction dilution analysis (AEDA). Bergamot-like odour components were (Z)-limonene oxide, decanal, linalyl acetate and geraniol. A mixture of eight other components, such as limonene, linalool, γ γ γ γ γ -terpinene and others, in addition to the four bergamot-like aroma compounds, brought about an aroma model of bergamot odour with the similarity of 7.1 by the nine-point-score sensory test.
