“…The total fatty acid composition of the lipid fraction and some characteristic volatile compounds present in the roasted coffee aroma were identified by GC-MS. Some of [4], [12], [17], [22], [23], [25]: Compounds with reference have been previously reported in the literature; # compounds contaminating the Porapak-Q polymer are present in the samples when previous treatment is not made. For its identification, it is necessary to use a blank.…”

“…4 Os éteres voláteis estão presentes no café torrado em quantidade não muito elevada. Dentre os éteres voláteis já identificados nesse produto estão, por exemplo, o metóxi-etano, 2-metóxi-2-metil-propano e o éter difurfurílico 14,67 . Este último (éter heterocíclico) pode ser destacado por estar presente em concentração mais elevada do que os demais (2 mg/kg de café torrado) 65 .…”
