Abstract
Blackberry (Rubus fruticosus) belongs to the Rosaceae family. It is very rich in essential and beneficial elements. In Morocco, despite its nutritional quality, this fruit remains among the forest species that are ignored. The present study has been focused on the physicochemical characterization of this species. The fruits have been harvested from the Mediterranean region of Morocco (Tangier-Tetouan-Al Hoceima). The analysis was made directly after the harvest for the determination of pH value, acidity, Total soluble solid, refraction index, total and reducer sugar levels. Results showed that the fruit is acidic (pH 4.65±0.32), rich in water (70%) and total sugars (27.43±2.67 mg/l). The variation of different physicochemical parameters in all fruit samples collected from different sites may be due to geographical distribution, climatic and edaphic parameters.
