Volatile components of peel oil and juice from Citrus unshiu were studied. The peel oil and aroma concentrate from the juice were separated into hydrocarbons and oxygenated compounds by column chromatography. These fractions were analyzed by gas chromatography and combined gas chromatography and mass spectrometry.
Ninety-eight percent of the peel oil consisted of hydrocarbons such as d-limonene, r-terpinene, myrcene and a-pinene. The aroma concentrate from the juice was composed of the same hydrocarbons (60%) and oxygenated compounds (40%) such as 3-methylbutanol, cis-3-hexenol, trans-2-hexanal and n-hexanal. Ninety percent of the oxygenated compounds was alcohols and aldehydes.
