Residue determination was performed on fruit 1 h after the treatment and at the end of storage (2 days at 0 ◦C and 3 days at 20 ◦C),
corresponding to consumption time.
Sample pre-incubation, extraction and injection on GC were performed through an automatic auto-sampler CombiPAL (CTC Analytics) under the following conditions: 10 min pre-incubation in the heated agitator block at the constant temperature of 80 ◦C and agitation speed of 250 rpm; insertion of the SPME needle in the sample vial and exposure of the fibre for 10 min extraction; insertion of SPME needle in the injector port and exposure ofthe fibre for 2 min at 260 ◦C, for compound thermal desorption.
