logo-ipb

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.

Kawista merupakan tanaman buah yang termasuk famili Rutaceae. Tanaman ini mulai langka dijumpai, padahal berpotensi besar sebagai bahan baku minuman maupun sebagai batang bawah tanaman jeruk. Tanaman muda asal biji yang dituhibuhkan secara asentis, diambil jaringan kotil, hipokotil, epikotil, ruas pertama dan daunnya untuk digunakan sebagai eksplan. Eksplan tersebut ditumbuhkan pada media dasar Murachige & Skoog (MS) dengan atau tanpa tambahan zat pengatur
