| [[https://nl.wikipedia.org/wiki/Elstar_(appel)|Elstar]] and [[https://en.wikipedia.org/wiki/Cox%27s_Orange_Pippin|Cox-Orange]] apple extracts were screened for potent odorants by aroma extract dilution analysis (AEDA). \\ | [[https://nl.wikipedia.org/wiki/Elstar_(appel)|Elstar]] and [[https://en.wikipedia.org/wiki/Cox%27s_Orange_Pippin|Cox-Orange]] apple extracts were screened for potent odorants by aroma extract dilution analysis (AEDA). \\ |
| (E)-β-Damascenone, (E)-β-damascone, hexanal, (Z)-3-hexenal , (Z)-2-nonenal, linalool, butyl acetate, 2-methylbutyl acetate, and hexyl acetate, were identified in [[https://en.wikipedia.org/wiki/Elstar|Elstar]]. \\ | (E)-β-Damascenone, (E)-β-damascone, hexanal, (Z)-3-hexenal , (Z)-2-nonenal, linalool, butyl acetate, 2-methylbutyl acetate, and hexyl acetate, were identified in //Elstar//. \\ |
| (E)-β-Damascenone, hexanal, (Z)-3-hexenal , (Z)-2-nonenal, ethyl butanoate, ethyl 2-methylbutanoate, 1-octen-3-one, (E)-2-octenal, methional, (E)-2-nonenal, eugenol, and wine lactone in [[https://en.wikipedia.org/wiki/Cox%27s_Orange_Pippin|Cox Orange]]. \\ | (E)-β-Damascenone, hexanal, (Z)-3-hexenal , (Z)-2-nonenal, ethyl butanoate, ethyl 2-methylbutanoate, 1-octen-3-one, (E)-2-octenal, methional, (E)-2-nonenal, eugenol, and wine lactone in //Cox Orange//. \\ |
| The release of odorants by the cultivars was analysed by gas chromatography-olfactometry of headspace samples. Ethyl butanoate, ethyl 2-methylbutanoate showed the highest odour activities in the air above Elstar apples and ethyl butanoate, acetaldehyde, 2-methylbutanol and ethyl methylpropanoate in that of Cox Orange. Preparation of a homogenate changed the headspace composition of potent odorants. Hexyl acetate became the key odorant of Elstar and aldehydes hexanal and (Z)-3-hexenal those of Cox Orange. Quantification and calculation of odour activity values indicated (E)-β-damascenone, (Z)-3-hexenal, linalool, butyl acetate, 2-methylbutyl acetate, and hexyl acetate as the character impact odorants of the fruit flesh of the two cultivars. Elstar contained more (E)-β-damascenone, (Z)-2-nonenal, butyl acetate and hexyl acetate and Cox Orange more (Z)-3-hexenal than the other cultivar. The concentrations of 2-methylbutyl acetate were similar. \\ | The release of odorants by the cultivars was analysed by gas chromatography-olfactometry of headspace samples.
