8 μm) using various temperature programs for the different extracts. Carrier gas was helium, and the injector temperature was set to 250◦ C. MS conditions were: transfer line temperature 280◦ C; energy of electron 70 eV, ion mass/charge ratio, 20–500 m/z. Typical chromatograms of fresh and stale longan are depicted in Fig. 6. The chromatograms illustrate the good separation capacity of the analytical system and indicate that storage exerts a marked influence on the aroma profile. 15. The application of the method was proposed for the investigation of the secondary metabolism in plants and for quality control purposes (Zhang and Li, 2007).

Identity Temprallino juce Temprallino skins Grenache juice 1 1 1 Grenache skins Abundance Identification based on coincidence of gas chromatographic retention and mass spectrometric data with those of the pure compound available in the lab. b Reliability: The pure compound was not available, but gas chromatographic retention and mass spectrometric data were coincident with those reported in the literature. d Reliability: Identification based in gas chromatographic retention data and odour quality.
5. 13. It was established that the method of drying (desiccator, sun, hot air, microwave) exerts a marked influence on the aroma profile of the samples. , 2007). SPME followed by GC-MS, GC-O and HPLC were simultaneously applied for the investigation of the changes in the aroma profile, chemical and physical properties of Yali pear (Pyrus bertschneideri Reld) during storage. , 2006). SPME coupled with GC-MS has also been employed for the investigation of the aroma composition of cantaloupe, Galia and honeydew muskmelons.
