Abstract:
The present study investigated the volatile organic
compounds (VOCs) in 14 Egyptian mango specimens collected
from three different regions and of different cultivars (cvs). VOCs
were extracted via solid-phase microextraction, followed by gas
chromatography−mass spectrometry analysis. The results obtained
for sesquiterpene hydrocarbons’ qualitative abundance were
represented by 28 peaks, whereas monoterpene hydrocarbons
amounted for the highest levels in most of the mango cvs.
Multivariate data analyses were employed for sample classification
and identification of markers. Unsupervised principal component
analysis revealed that “zebdia” cv from the three origins combined
together being enriched in terpinolene. Moreover, supervised
orthogonal partial least square-discriminant analysis identified β-
terpinene and (Z)-geranylacetone in the premium “awees” cv. The impact of probiotic bacteria on mango juice aroma was further
assessed revealing no potential changes in the composition. This study provides the first comprehensive insights into Egyptian
mango aroma and reveals that the cv type overcomes the geographical origin in their aroma profile.
