- Abstract
The aim of this study was to extract and identify volatile compounds from passion fruit residues generated during processing. Distillates of passion fruit residues were obtained from the techniques of simple hydrodistillation and hydrodistillation by passing nitrogen gas. The volatile compounds present in the distillates were captured by solid phase microextraction with Carboxen/DVB/DMS fiber. The volatile compounds were indentified by gas chromatography with mass spectrometry using a fused sillica capillary column with a CP WAX 52 stationary phase. Thirty one compounds were indentified by simple hydrodistillation technique. The main compounds were: neral (26.19%), methyl cinnamate (18.52%), linalool (16.82%), 1-undecanol (5.60%), cis-linalool oxide (4.41%), benzaldehyde (3.92%) and 1-hexanol (3.48%). For the hydrodistillation by passing nitrogen gas, thirty compounds were identified and the ones which presented higher area percentage were: methyl cinnamate (30.41%), neral (24.46%), β-ionone (13.81%), linalool (4.0%) and butanoic acid (2.19%). The present study revealed that passion fruit waste contained volatile compounds that could be extracted as aromas products, presenting potential for the production of value-added natural essences.
