Analysis of volatile compounds in some typical Brazilian fruits and juices by SPME-GC method

Food Addit Contam. 2005 Jun;22(6):508-13. doi: 10.1080/02652030500132893.

Abstract

This paper describes the analysis of volatile organic compounds (VOC) in typical Brazilian fruit and fruit juices by a solid-phase microextraction (SPME) method using a capillary gas chromatography system with flame ionization detection and mass spectrometry (GC-MS). A SPME holder with a 100-microm polydimethilsiloxane fibre coating was utilized. The optimal conditions were desorption at 220 degrees C for 1 min, absorption at 50 degrees C for 20 min and 4.00 ml of sample in the headspace vial. The method gave good precision and showed a linear response. More than 100 VOC were identified in the fruit and juices studied by GC-MS. The method was employed to quantify ethanol, naphthalene and benzoic acid in four different species of Brazilian fruit and their juices.
