Recherches sur les arǒmes 13e communication [1] Sur 1′ arǒme de café. I

Abstract: The analysis of a coffee concentrate is described: 202 constituents have been identified, 154 of which for the first time. Some of these compounds are new chemicals; their synthesis is described. Most identifications are based upon mass spectrometry combined in many cases with IR. spectrometry and comparison with reference compounds. MS. and IR. data are given in detail. The analysis shows that a large number of minor constituents is present, many of which could not be identified.

“…Furfuryl mercaptan, which, at this dilution, has a flavour described by the terms sulphury, rubbery, mealy and burnt, has been reported as a constituent of a heated model system containing glucose, hydrogen sulphide and ammonia43 and has also been isolated from coffee. 46 It has similarly been found38 that 2-acetylthiophene is present in greater concentrations in ales than in lagers, but in the case of ales and lagers, unlike the present situation, thiophene-2-carboxaldehyde was found to be present in similar concentrations.…”

“…O 2-metóxi-fenol (guaiacol) e seus derivados também foram descritos por vários autores 4,[9][10][11][12][13]17,18 . Os fenóis encontrados em maior quantidade no café torrado são: o 4-vinil-guaiacol (8-20 mg/ Kg de café torrado), o guaiacol (2-3 mg/Kg) e o fenol (1,2-2,2 mg/Kg) 19 .…”
