| Résumé : |
The volatile profile of Kiyomi cold-pressed peel oil was investigated by gas chromatography and gas chromatography/mass spectrometry.
Among the 59 components quantified in Kiyomi oil, 25 terpene hydrocarbons and 32 oxygenated compounds were identified, with peak weight percentages were 97.1% and 2.4%, respectively. Limonene was the most prominent compound (92.0%), followed by myrcene (2.4%), sabinene (0.9%), octanal (0.6%), α-pinene (0.5%), β-phellandrene (0.5%) and neryl acetate (0.5%). A peculiarity of the volatile profile of Kiyomi oil was the content ratio of alcohols (0.3%) to aldehydes (1.5%), which resulted from the relative abundance of octanal and decanal. Octanal and neryl acetate, major oxygenated components in Kiyomi oil, were determined to be the momentous flavor components characterizing the volatile composition of Kiyomi oil because of their high proportions. Nootkatone (0.1%) was also suggested as an important volatile component of Kiyomi oil for discriminating among the essential oils of sweet citrus such as oranges and mandarins including Satsuma mandarin, a parent of Kiyomi. |
