Abstract
This study provides a comprehensive characterization of “Majhoul” dates (Phoenix dactylifera L.) from four major growing regions of Drâa-Tafilalet area Morocco (Boudnib, Erfoud, Goulmima, and Zagora). The research aimed to evaluate the impact of local conditions on fruit quality through integrated physicochemical, biochemical, and microbiological analyses. Significant variations were observed across localities: moisture content ranged from 20.59 % to 25.00 %, water activity (aw) from 0.618 to 0.766, and total sugars from 72.23% to 75.87%. These compositional differences directly influenced microbial stability, with higher moisture correlating with increased microbial risks. Biochemically, protein content varied significantly (1.74%-1.98 %), while lipid content remained consistently low (0.1 %). Microbiological assessment revealed excellent hygienic quality with the absence of pathogenic bacteria (E. coli, Salmonella, Listeria) but showed elevated fungal mesophilic aerobic thermophilic loads in Zagora samples (4×10⁶ colony-forming units per gram (CFU)/g), indicating the need for optimized postharvest management. The findings demonstrate that local factors significantly determine Majhoul date quality and underscore the importance of controlled drying and storage conditions for enhancing preservation, safety, and marketability of this economically important variety.
