GC-MS analysiswas performed using an Agilent 7890A gas chromatograph
equipped with a CPWAX capillary column (60 m × 0.25 mm i.d. ×
0.25 μmFT) and coupled to a BenchToF Time of FlightMass Spectrometer
(Almsco, UK) and a CTC CombiPal autosampler (CTC Analytics AG,
Zwingen, Switzerland). HS-SPME was performed on the aqueous extracts
used for sensory evaluation (200 μL) in 2 mL of saturated NaCl solution.
The samples were incubated at 40 °C for 40 min followed by a
1 min extraction using a CAR/PDMS/DVB SPME fibre and desorption at
260 °C for 10 min. The oven temperature was programmed as follows:
initial temperature 40 °C (held for 5 min), 40–200 °C at 4 °C/min, then
to 250 °C at 8 °C/min, held for 5 min. Heliumwas used as the carrier gas
at a flow rate of 1 mL/min.
