Abstract

Algeria, the third world's date producers, has thousands date palm varieties, but little is known about the nutritional value and composition of these varieties. Ten native date varieties from different oases were discriminated via their physical and chemical properties as well as phyto-chemical composition and their antioxidant capacity. High significant varietal differences were observed in the studied characteristics, permitting for distinguishable ranks among date varie-ties. The highest morphological traits (fruit size and pulp content) were noted for Arechti, Cherka and Feggus varieties. High antioxidant activity was detected in Arechti, Timdjuhart and Feggus, while the high phenolic compounds were found in Feggus, Arechti and Timdjuhart. Principal Component Analysis revealed a consistent grouping of Arechti, Timdjouhart and Feggus from the rest of varieties.
