GC-MS conditions: Gas chromatograph Saturn 2200 (Walnut Creek, CA, USA) GC-SM, which is GC<br />
Varian 3800, provided of an injector split/splitless, a fused silica capillary column DB-Wax (J&W<br />
Scientific, Folsom, CA, USA) was used (30m x 0.25 mm i.d., film tickness, 0.25 µm), and a mass<br />
spectrum detector series 2000 that captures electrons to identify the molecules by electronic impact.<br />
The temperature program was: increased of 40 to 200 ºC (at 3 ºC/min), then from 200 to 248 ºC (at 5<br />
ºC/min) and maintained for 15 min. The injector temperature was maintained at 250 ºC and the<br />
detector temperature was 300 ºC.<br />
RESULTS AND DISCUSSION<br />
The concentration of volatile compounds was determined in milligrams by kilogram of pulp for all<br />
techniques, considering the sum of the total area of all the compounds detected by GC-FID, that is , all<br />
the free volatile compounds (VC) which include aroma compounds (AC).<br />
The total concentration of VC (mg/kg) from varieties was compared by analysis of variance (ANOVA)<br />
of a statistic design 8X4, the results showed a significant effect (p
