| "...the current study aimed to elucidate the smell of pine wood by analysing the odour-active substances in three Pinus sylvestris L. samples... dedicated odorant analysis techniques such as gas chromatography-olfactometry (GC-O) and aroma extract dilution analysis (AEDA) were applied and successfully detected 44 odour-active compounds; of these, 39 substances were successfully identified by gas chromatography-mass spectrometry/olfactometry (GC-MS/O) and two-dimensional gas chromatography-mass spectrometry/olfactometry | To elucidate the smell of pine wood, solvent-assisted flavour evaporation (SAFE) of volatiles from pine wood shavings followed by dedicated odorant analysis techniques such as gas chromatography-olfactometry (GC-O) and aroma extract dilution analysis (AEDA) was applied. Of 44 odour-active compounds, 39 were identified by two-dimensional gas chromatography-mass spectrometry/olfactometry (2D-GC-MS/O). The majority of the identified odorants were fatty acid degradation products, plus some terpenoic substances and odorous substances resulting from the degradation of lignin. Highest flavour dilution factors (FD>=243) showed α-pinene (woody resinous), hexanal (green grassy), octanal (citrus), (E)-non-2-enal (fatty), linalool (citrus), (E)-dec-2-enal (fatty), (E,E)-nona-2,4-dienal (fatty), pentanoic acid (cheesy), (E,E)-deca-2,4-dienal (fatty), heptanoic acid (pepperoni-like, plastic), δ-octalactone (coconut), γ-nonalactone (peach), (E,Z,Z)-trideca-2,4,7-trienal (fruity blood-like metallic), δ-nonalactone (sweet coconut), nonanoic acid (leather artificial soapy), sotolone (savoury), α-bisabolol (balsamic pepper-like), phenylacetic acid (honey-like), vanillin (vanilla-like), 3-phenylpropanoic acid (vomit-like fruity), an unidentified androstenone-like substance (perfume-like) and thymoquinone (pencil-like). \\ |
| (2D-GC-MS/O). Among the main odorants found were (E,E)-nona-2,4-dienal, vanillin, phenylacetic acid, 3-phenylpropanoic acid, δ-octalactone and α-pinene, all of them having been detected with high flavour dilution factors during GC-O analyses. The majority of the identified odorants were fatty acid degradation products, plus some terpenoic substances and odorous substances resulting from the degradation of lignin. Although some of the detected substances have previously been reported as constituents of wood, 11 substances are reported here for the first time as odour-active compounds in wood, amongst them heptanoic acid, γ-octalactone, δ-nonalactone and (E,Z,Z)-trideca-2,4,7-trienal." \\ | [Schreiner, L., Bauer, P., & Buettner, A.

| | Using stable isotope dilution analysis (SIDA) and odor activity values (OAVs) calculated on the basis of odor thresholds determined in cellulose, hexanal, octanal, (E)-non-2-enal, p-cresol, vanillin, and thymoquinone were the dominant odorants for wood odor of several softwood species (Pinus sylvestris, Larix decidua, Calocedrus decurrens, Abies concolor, and Picea abies). \\ |
