 "Volatiles from the juice of the American cranberry (Vaccinium macrocarpon Ait.) were investigated using gas chromatography, mass spectrometry and infrared spectrophotometry. Forty-two compounds comprising over 95% of the aroma complex were identified. These consist of 14 aromatic compounds, 7 terpenes, 9 aliphatic alcohols, 6 aliphatic aldehydes and 6 other compounds including the 2 acids, benzoic and 2-methylbutyric. The aromatic compounds (benzaldehyde, benzyl and benzoate esters) and the terpenes appear to be the major contributors to the aroma of cranberry juice. The remaining 5% of the aroma complex contains over 200 components. Although these compounds occur in very small concentrations, they appear to be important in the overall aroma." \\

+Of the 35 odor-active compounds detected by applying AEDA on the liquid ectract of cranberry, highest FD factors showed terpinolene (piney, sweet), decanal (citrus, peel), benzoic acid (balsamic), heptan-3-one (strong fruity, green, fatty), octen-3-one (mushroom), and (2E)-nonenal (waxy, cucumber), and are considered most important odorants in cranberry fruit. The main contributors to the aroma of cranberry fruit are esters (ethyl acetate, methyl butyrate, ethyl butyrate, benzyl acetate, anisyl acetate), terpenes (p-cymene, terpinolene, alpha terpineol), aldehydes (hexanal, octanal, nonanal, 2E-nonenal), acids (acetic acid, butyric acid, 2-ethylhexanoic acid, nonanoic acid, cinnamic acid, palmitic acid), two lactones (gamma tridecalactone, delta tetradecalactone), one one sulfur-compund, and one sulfur-nitrogen compound (2-isopropylthiazole). Compounds with relatively low FD factors included linalool oxide (floral, woody), trans-anethole (herbaceous), phenylethanol (floral), and vanillin. \\

 Of the quantified compounds found with odor activity values (OAVs > 1) in four cultivars of cranberries (Early Black, Howes, Searles, and McFarlin), hexanal (OAV 27-60), pentanal (OAV 31-51), (E)-2-heptenal (OAV 17-66), (E)-2-hexenal (OAV 18-63), (E)-2-octenal (OAV 10-28), (E)-2-nonenal (OAV 8-77), ethyl 2-methylbutyrate (OAV 10-33), β-ionone (OAV 8-73), 2-methylbutyric acid (OAV 18-37), and octanal (OAV 4-24) contributed most to the aroma of cranberry. The Searles cultivar was highly correlated with the sensory descriptors “floral” and “fruity”, and the McFarlin cultivar was greatly related to the sensory descriptors “mellow” and “green and grass”. \\
