Values expressed by GC–MS area response × 106 - average of 4 fruits per treatment. Identification by matching RI and/ or mass spectra from libraries NiST129 by equal ≥ 90. Different letters in the same row indicate significant differences by Duncan test (p < 0.05) applied after ANOVA. Odor-active compound identified by SPME GC-O for Pino (2014)c; Ulrich & Wijaya (2010)d
