Morphological, physicochemical, biochemical, phytochemical and sensory characteristics of date fruits of cultivars Deglet Noor, Tamesrit, Ghars, Tinissine and H’mira were investigated. External and internal fruit quality was assessed by different parameters: fruits and cores weights and dimensions, pH, salt content, water, sugar, proteins, lipids, polyphenols and Flavonoids. Sensory quality was performed by panel tests of size, aroma, color, texture and sweet/acid taste of fruits. The studied varieties showed a low content in fat and proteins, but important amounts of sugars, dietary fiber, potassium and polyphenols. These results suggest that the five varieties are a good source of essential and important nutrients on health. The dates have significantly distinct characteristics; Tamesrit had the highest weight (14,66 g) compared to other varieties; Deglet Noor showed significantly (p<0,05) higher level of sugar (70%) particularly sucrose (29%) against 0% in Tamesrit and finally Tinissine contained significantly (p<0,05) higher levels of polyphenols. Differences in sensory scores of fruit were found between cultivars; showing a high preference score for Tamesrit cultivar.
