Abstract

Bu calismada Coffea arabica L. (Rubiaceae)’nin yesil ve kavrulmus cekirdeklerinin ucucu bilesikleri incelenmistir. Ucucu bilesenler, Headspace Kati Faz Mikroekstraksiyon (HS-SPME) teknigi ile elde edilmis ve Gaz Kromatografisi-Kutle Spektrometresi (GC/MS) ile analiz edilmistir. Yesil kahve cekirdeklerinin ana bilesenleri izoamilalkol (% 10.4), hekzanal (% 10.4) ve hekzakosan (% 8.2) iken, kavrulmus cekirdeklerin ana bilesenleri forfurilalkol (% 13.6), forfurilasetat (% 10.7) ve 5metil forfural (% 9.27) olarak belirlenmistir. Sonuc olarak, HS-SPME-GC-MS kullanilarak yesil ve kavrulmus kahve cekirdeklerinde alkol, aldehit, keton, pirazin, piridin ve furan gibi degisik kimyasal gruplara ait farkli ucucu bilesenlerin belirlenmesi mumkun olmustur." seklinde olmalidir

阿拉比卡咖啡L.绿豆和烤豆的挥发性化合物
在calisma中,小粒咖啡(茜草科)没有以肥料和纤维为代价进行检查。采用顶空Kati相微牵引(HS-SPME)技术对飞机专家进行诊断,并用气相色谱立方体光谱仪(GC/MS)进行分析。关于生咖啡脑的主要知识是异戊拉醇(%10.4)、己醛(%10.40)和己糖(%8.2),后者被定义为磷醇(%13.6)、呋喃酯(%10.7)和5-甲基呋喃酯(%9.27)。因此,我不得不发现,与HS-SPME-GC-MS相关的不同化学物质在不同的化学物质中与醇、赤铁矿、酮、吡嗪、吡啶和呋喃不同。“必须井然有序
