Aroma Profile Discrimination of Coffees and Industrial Blends According to the ...
Rodrigues, Carla Igreja; Máguas, Cristina; Nogueira, J.M.F.In the present work, static headspace solid phase microextraction using carboxen/polydimethylsiloxane polymeric fibre (HS-SPME(CAR/PDMS)) followed by gas chromatography-mass spectrometry (GC-MS), revealed the best analytical performance to characterize the aroma profile of coffees and industrial blends with different chromatic values (64.9, 70.6, 75.3, 86.1 and 89.6). The most relevant classes of aroma compound...
Comparing total nitrogen and crude protein content of green coffee beans (Coffe...
Rodrigues, Carla Igreja; Maia, Rodrigo; Máguas, CristinaA combustion - TCD (thermal conductivity detection) elemental analysis method has been applied for the first time for total nitrogen and crude protein determination of 72 green coffee bean samples from 20 different geographic origins distributed over North America, South America, Africa, Asia and Oceania. Crude protein content varied among different coffees from distinct geographic origins. In this study we aim...
