Summary

Eleven diphenols and seven caramel compounds were extracted from roasted coffee with pentane/ether (1 + 1), silylated with BSTFA, characterized, and semiquantified by GC-MS. Seven phenols and five caramel components were identified for the first time in roasted coffee.Robusta coffee contained the highest amounts of phenols and maltol.Arabica showed higher amounts of furaneol (2.5-dimethyl-4-hydroxy-3(2H)-furanone), isomaltol, 5-hydroxymaltol, and 5-hydroxy-5.6-dihydromaltol.

Zusammenfassung

Elf Diphenole and sieben Caramelkomponenten wurden aus entfettetem Röstkaffee durch Extraktion mit Pentan/Äther (1 + 1) isoliert und nach Silylierung mit BSTFA gaschromatographischmassenspektrometrisch charakterisiert and größen-ordnungsmäßig bestimmt. Sieben Phenole und fünf Caramelkomponenten konnten erstmals in Röstkaffee identifiziert warden. Robustakaffee besitzt die größten Mengen an Phenolen and Maltol, während Arabica-kaffee die höchsten Konzentrationen an Furaneol (2,5-Dimethyl-4-hydroxy-3(2H)-furanen), Isomaltol, 5-Hydroxymaltol and 5-Hydroxy-5,6-dihydro-maltol aufweist.
