Abstract
The present comparative study aimed to investigate for the first time some physical and antioxidant properties of date fruits from Phoenix dactylifera L. (cv. Mech-Degla) (MD) and Phoenix canariensis L. (CRD) palms. The physical properties of whole date fruits and date fruit seeds were analyzed separately. But the antioxidant potential (AP), evaluated throughout total phenolic content (TPC), reducing power (RP) and antiradicalar activity (AA) towards the stable free radical 2,2-Diphenyl-1-picrylhydrazyl (DPPH) were analyzed in different tissues of date fruit fleshes. Results showed that linear dimensions, equivalent diameter, volume, mass, sphericity, surface area, bulk density, porosity, angle of repose and hardness, were statistically different (p
