 "... dividing the concentration (ppm) by the threshold (ppm) for bitter orange [peel oil], it can be seen that the most important odour characters in the oil are octanal, decanal, linalool, nonanal and linalyl acetate... the odour characters of petitgrain and neroli are obviously linalool and linalyl acetate; however, the odour character of lesser importance in these oils are nonanal, α-terpineol, geranial, and nerol for petigrain oils and methyl N-methylanthranilate, indole, geranial, (E)-nerolidol, methyl anthranilate and α-terpineol in neroli oil." \\ "... dividing the concentration (ppm) by the threshold (ppm) for bitter orange [peel oil], it can be seen that the most important odour characters in the oil are octanal, decanal, linalool, nonanal and linalyl acetate... the odour characters of petitgrain and neroli are obviously linalool and linalyl acetate; however, the odour character of lesser importance in these oils are nonanal, α-terpineol, geranial, and nerol for petigrain oils and methyl N-methylanthranilate, indole, geranial, (E)-nerolidol, methyl anthranilate and α-terpineol in neroli oil." \\

 +Flavour components of C.aurantium essential oil (EO) were characterized by GC-MS and GC-O. Potent odour contributors were α-pinene (floral), octanal (green), limonene (citrus), linalool (floral), α-terpineol (indeterminate: ‘ND’, green), linalyl acetate (floral), (E,E) or (E,Z)-2,4-decadienal (frying), dodecanal (ND), caryophyllene (green) and an unknown compound (IT = 1678, plastic note). "Interestingly, the EO odour was also characterized by five volatile compounds (FD: 6/9 to 7/9) responsible for fresh, plastic notes in trace amounts not allowing identification. These compounds with a high IT (IT >1630) were smelled but not detected in GC conditions." \\
