摘要

Volatile extracts of two wild cabbages, Brassica cretica and Brasska insularis, were studied by GC-MS, GC/FID, and GC-olfactometry/aroma extract dilution analysis (GC-O/AEDA). Major compounds were 3-butenyl cyanide (70% of the total GC/FID area) and 3-butenyl isothiocyanate (29%) in B. cretica and 2-phenylethyl cyanide (53%) and 2-phenylethyl isothiocyanate (21%) in B. insularis. AEDA revealed the impact of five heteroatomic trace compounds (diacetyl, methional, furfuryl thiol, 1-octen-3-one and skatole) with moderate to high flavour dilution (FD) factors that were detected only due to GC-O analyses.
