The volatiles of the kawista fruit (wood apple) were analyzed by gas chromatography (GC) and a combined gas chromatography-mass spectrometer (GC-MS). Character impact odorants of the fruits were systematically characterized by aroma extract dilution analysis (AEDA) with GC-Olfactometry (GC-O). A total of 75 compounds were identified, including 28 esters, 11 alcohols, 10 aldehydes, 1 acetal, 10 ketones, 4 lactones, 1 heterocyclic, 4 aliphatic hydrocarbons, 1 furan and 5 acids. However, only 44 volatiles were detected by GC-O. Among these, compounds with the most impact were ethyl butyrate (fruity, sweet, banana-like) and methyl butyrate (fruit, sour) with a flavor dilution factor of 256 and 64, respectively.
