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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
