Abstract
In this paper the volatile composition of some cultivars of broccoli, cauli flower and cabbage was studied. The volatile substances were extracted and concentrated from each sample using a microwave-KS112 resin coupled techniq ue. The obtained volatile extracts were analysed by GC/MS. All the cultivars ha d most of the volatile compounds of the Brassicacee family and trisulfide d imethyl was more prevalent than the other volatile compounds. For the volat ile characteristic compounds, cauliflower had the higher number containing N and S (63%); while in the broccoli and cabbage species, they were respect ively 42% and 39% of total aroma. Cabbage contained more isothiocyanates and nitriles than the other two spec ies; while in the cauliflower species sulfures and thionitriles had greater values.
