| "The volatile components of bilberry, bog blueberry and cultivated high-bush blueberry (cv. Rancocas) were analysed by gas chromatography and mass spectrometry. Several new compounds not reported previously as blueberry volatiles were detected. These included methyl and [[http://www.thegoodscentscompany.com/data/rw1582571.html|ethyl 2-hydroxy-3-methylbutanoate]], methyl and ethyl 3-hydroxy-3-methylbutanoate, 2-phenylethyl formate, methyl salicylate, farnesol, farnesyl acetate, vanillin, myristicine, 4-vinylphenol, 2-methoxy-5-vinylphenol, citronellol, hydroxycitronellol and some γ- and δ-lactones. The character impact compounds of bilberry were found to be the above-mentioned hydroxy esters together with 2-phenylethanol and its esters and the γ- and δ-lactones, whereas myristicine, citronellol, hydroxycitronellol, farnesol and farnesyl acetate were typical of the aroma of high-bush blueberry." \\ | "The volatile components of bilberry, bog blueberry and cultivated high-bush blueberry (cv.

| | Of the 35 odor-active compounds detected by applying AEDA on the liquid ectract of blueberry, highest FD factors showed ethyl 2-methylbutyrate (green, slightly apple-like), hexanal (fatty green, grassy), octanal (orange fatty), isothiazole (skunk, sulfury), octen-3-one (mushroom), (E,E)-2,4-heptadienal (fatty, green, greasy), and (E,E)-2,4-decadienal (deep fatty, slightly citrus note). The esters (methyl butyrate, ethyl isobutyrate, methyl isovalerate, rthyl 2-methylbutyrate, and ethyl isovalerate) with fruity and floral notes gave FD factor 4. The same FD factor of 4 had alcohols like isoamyl alcohol, octanol, and decanol as well as linalool oxide and isovaleric acid. Sulfur compounds like dimethyl sulfide (FD 7), thiazole, isothiazole, dodecyl mercaptan, ortho-methylthio phenol (FD 4), and 1-p-menthene-8-thiol (FD 1) also seem to contribute to the aroma of blueberry. Other characteristic floral, tea like, and spicy notes with low FD factor were damascenone, β-damascone, phenylethanol, α-methylionone, and cinnamic aldehyde. \\ |

| "... HS-SPME analyses revealed complex volatile profiles including terpenes (23 compounds, e.g. p-cymene, 1,8-cineole, linalool) and aromatic structures (10 compounds, e.g. benzaldehyde, ethyl benzoate, 2-phenylethyl acetate, benzyl benzoate), which contribute to the characteristic and flavourful blueberry aroma... The most abundant compounds were related to the group of C6-structures or so-called ‘green leaf volatiles’... In addition, impact-aroma compounds belonging to the chemical group of monoterpenes, could also be extracted from all samples, e.g. 1,8-cineole, linalool, and linalyl acetate." \\ | "...
