then 4°C/min up to 180°C, then 10 min at
180°C. The split ratio was 1:10, the injector port was
kept at 230°C and the FID at 250°C. The chromato-
graphic peaks were identi®ed and quanti®ed using a
known concentration of standard, dissolved in a 10%
sugar solution and analysed in the same conditions as
the samples.In order to validate the identification of the
peaks,a know namount of the commercial standard was
added to the melon pulp and analysed like the other
samples.
