This study investigated the composition of the aroma substances and the physicochemical
properties of lyophilized coffee produced from Ecuador Arabica and robusta coffee beans. In the present
study, we propose a fast method of analyzing volatile compounds in coffee using the headspace solid phase
extraction method (HS-SPME) combined with gas chromatography-mass spectrometry (GC-MS). According
to the results, 25 aroma compounds were detected in coffee, the most important of which are 2-acetylfuran,
2-furanmethanol, 2,3-dimethylpyrazine, 2,3,5-trimethylpyrazine, and 2-methoxy-4-vinylphenol. As is
known, furans and pyrazines are associated with "roasted, cocoa, coffee, and hazelnut" odours. The most
important organic acids detected in the study are citric, maleic, and succinic.
