Abstract
Volatile components in the needles of Pinus densiflora (red pine), a conifer native to Korea, were extracted by simultaneous distillation-extraction. Gas chromatography-mass spectrometry showed that α-pinene is the most abundant compound, followed by β -phellandrene, germacrene D, β-caryophyllene, and myrcene. In aroma extract dilution analysis, α-pinene (pine/fresh) was determined to be the most intense aroma-active compound, with a high flavour dilution factor. (Z)-3-Hexenal (green/apple) and bornyl acetate (pine/herbaceous) were also identified as important aroma-active compounds. These aroma-active compounds were also detected through headspace solid-phase microextraction-gas chromatography-olfactometry, using polydimethylsiloxane (PDMS) and Carboxen-PDMS fibres.
