Relative levels (fold changes) of VOCs detected in juices of four Citrus varieties.

Data are normalized to the mean values in the Chandler variety, unless otherwise indicated. Mean corresponding to n = 6 values. Means followed by different letters in the same row are significantly different (pAld: Aldehyde; Ket: Ketone; Alc: Alcohol; Est: Ester; Fur: Furane; Mt hd: Monoterpene hydrocarbon; Sqt: Sesquiterpene; Ar: Aromatic hydrocarbon; Mt cyc ether: Monoterpene cyclic ether.aMonoterpene derived compound.bIn addition to the alcohol group, it has a tetrahydrofuran group.cSesquiterpene compound.dNorcarotenoid compound.eData normalized to the mean abundance in Fortune variety.fData normalized to the mean abundance in Clemenules variety.gData normalized to the mean abundance in Powell variety.hIts cyclic ether group is an epoxy group.*Compound reported for the first time in a Citrus juice.
