The flavour composition of the cardamom oil obtained by enzyme pre-treatment and control oil was identified by gas chromatography (GC) Agilent 6890 gas chromatograph (Palo Alto, USA) with a capillary column (HP-1 methyl siloxane, 50 m × 200 m × 0.33 m), with a temperature program: initial temperature 50◦C and raised to 250◦C, at the rate of 4◦C/min,with injector at 180◦C, detector at 280◦C. and hydrogen flow of 3 mL/min. with a flame ionization detector (FID). Cardamom oil sample (0.2 L) was injected into the GC.
