"Aroma extract dilution analysis was used to determine that the primary aroma compounds of muskmelon (C. melo) were ethyl 2-methylpropanoate, methyl 2-methylbutanoate, (Z)-3-hexenal, (E)-2-hexenal, 1,8-cineole, and (Z)-1,5-octadien-3-one. In our analyses, methyl 2-methylbutanoate, ethyl 2-methylpropanoate, and ethyl 2-methylbutanoate increased markedly with fruit maturity, and other esters such as ethyl butanoate and hexyl acetate... had similar trends. Although 3-methyl-1-butyl acetate is reported to be flavor related in muskmelon, our recovery was rather low, and the 2-methyl-1-butyl acetate stereoisomer was the predominant coeluting peak recovered. Also, (E)-2-hexenal varied insignificantly and eucalyptol recovery was highest in 1/4 slip and over-ripe fruit (data not shown). Variable compound recovery can be expected because significant genetic and biochemical differences exist between different varieties of cantaloupe, honeydew, and Charentais melons. Other compounds, possibly including alkenyl acetates, may be significant with regard to cantaloupe flavor, and varietal/genetic effects are highly important... We did not recover nonyl acetate or (Z,Z)-3,6-nonadienal in cantaloupe, but many aldehyde stereoisomers, such as (E,E)-2,4-hepta-dienal, (Z)-3,7-dimethyl-2,6-octadienal, (E)-3,7-dimethyl-2,6-octadienal, (E,E)-2,4-nonadienal, (E,Z)-2,4-nonadienal, (E,Z)-2,6-decadienal, and (E,E)-2,4-decadienal, were recovered. Z,Z isomers are highly unstable, and our method may have resulted in recovery of both E,Z and E,E dienals via isomerization. We also recovered other C9 aliphatic compounds in cantaloupe, including nonanal, (Z)-6-nonenal, (E)-2-nonenal, 1-nonanol, and (Z)-6-nonen-1-ol." \\ | "Aroma extract dilution analysis was used to determine that the primary aroma compounds of muskmelon (C. melo) were ethyl 2-methylpropanoate, methyl 2-methylbutanoate, (Z)-3-hexenal, (E)-2-hexenal, 1,8-cineole, and (Z)-1,5-octadien-3-one.
