D’Agostino, Maria F. published the artcileBlackberries (Rubus ulmifolius Schott) from Calabria (Italy): a comprehensive characterisation, Synthetic Route of 5405-41-4, the main research area is Rubus ulmifolius Schott quality characterization.
The establishment of the corresponding standards of quality to promote the commercialization of Rubus ulmifolius Schott (Rosaceae) blackberries from Calabria (Italy) has been aimed in this study. Data on the volatile composition gathered by Solid-Phase Microextraction (SPME) followed by GC-MS have been complemented with the study for the first time of physicochem. parameters and antioxidant capacity of wild and cultivated blackberries collected in seven different locations of Calabria. Wild fruits showed significantly higher dry matter content (16.34-22.14%) and pH (3.92-5.12) and lower total acidity (0.23-0.74 as % of citric acid) compared to the cultivated sample (dry matter: 15.31%; pH: 3.30 and total acidity: 1% citric acid), whereas color and total soluble solids were similar. Antioxidant capacity (DPPH assay) of wild blackberries, correlated (r = 0.71) with results from ABTS assay, was significantly higher (SE50 = 1.6-3.4 mg DW), in agreement with its higher content of total anthocyanins and total phenolics. Ethanol (11.8-32.4%), trans-2-hexenal (2.7-21.3%), methylbutanal (5.7-17.4%), and Et acetate (4.6-11.9%) were the major compounds in both wild and cultivated blackberries. Although the presence or relative concentration of several volatiles (e.g. p-cymen-8-ol, decanal, 3-hydroxy esters, etc.) seemed to be characteristic of the harvest location/blackberry type, further research on a higher number of samples should be carried out to confirm these results. The comprehensive characterization addressed for the first time in this paper is a valuable preliminary contribution to satisfy the demand by consumers and farmers of objective data to support the premium quality of Calabrian blackberries.
