Optimization of headspace sampling using solid-phase microextraction (SPME) for volatile components in starfruit juice
Volatiles are important flavor compounds of fruit juices and beverages. In this study, a headspace Solid-phase microextraction (SPME) gas chromatography-mass spectrometry (GC-MS) was used to analyze volatile components in starfruit juices. Several experimental parameters (e.g. adsorption temperatu...

| description | Volatiles are important flavor compounds of fruit juices and beverages. In this study, a headspace Solid-phase
microextraction (SPME) gas chromatography-mass spectrometry (GC-MS) was used to analyze volatile
components in starfruit juices. Several experimental parameters (e.g. adsorption temperature, adsorption time
and sample volume) were optimized to improve sampling efficiency in two aspects; maximum adsorption and
selective adsorption of volatile components onto SPME fiber. The following conditions was found to be optimal
for selectivity and sensitivity: adsorption temperature of 50oC for 30 min with a 65 μm divinylbenzene
/polydimethylsiloxane (DVB/PDMS) coated fiber with and sample volume of 15 g in a 30 ml vial. The proposed
technique could be applied for the analysis volatile compounds that contribute to starfruit juices flavor in
different cultivars and also their ripening stages. |
