| Abstract: | In order to investigate the volatile composition of the siriguela fruit (Spondias purpurea L.), the pulp of the fresh fruit was submitted to solid phase microextracton (SPME) using different fibers, divinylbenzene-carboxen-polydimethylsiloxane (DVB/CAR/PDMS), carbowax-divinylbenzene (CW/DVB), carboxen-polydimethylsiloxane (CAR/PDMS) and polydimethylsiloxane (PDMS) fibers. DVB/CAR/PDMS showed to be the more efficient qualitative and semi-quantitatively fiber in trapping these compounds. It was made possible to identify ketones, alcohols, aldehydes, esters and terpenic hydrocarbons in the headspace. The major compounds identified were hexanal, trans-2-hexenal, 3-hexen-1-ol, 2-hexen-1-ol, ethyl acetate and hexyl acetate. To have a clear picture of the retention indices of these compounds a new protocol, in which the standard hydrocarbon mixture is submitted to SPME, was developed and successfully used. |
