Medina, Sonia published the artcileDifferential volatile organic compounds signatures of apple juices from Madeira Island according to variety and geographical origin, Formula: C4H10OS, the main research area is apple juice volatile organic compound Portugal.
One of the main food authenticity issues is related to productsâ?false labeling concerning their variety or geog. origin. For this reason, the aim of this study was to establish distinctive characteristics for the discrimination of apple juices according to regional varieties (Rijo, Verde, Ribeiro and Azedo) and geog. origin (Prazeres and Santo da Serra (Madeira Island)) on the basis of their volatile pattern by headspace solid-phase microextraction combined with gas chromatog. mass spectrometry (HS-SPME/GC-MS) combined with chemometric tools. The results obtained revealed a perfect discrimination between the different apple varieties, with Rijo apple juices as samples with the major relative concentration of ethanol, Et butanoate, Et 2-methylbutanoate and Et hexanoate. Moreover, this study allowed a geog. origin-based classification of Azedo apple juices, highlighting Et acetate, 2-methyl-1-propanol, Et hexanoate, and toluene (described for the first time in apple juices) as discriminatory features. This study demonstrated that volatile organic compounds (VOCs) could serve as authenticity indicators to verify variety and geog. origin of apple juices, providing local producers multiple benefits and legal protection against misuse of the products.
