英文摘要	Cowpea is among the most grain legumes consumed in Algeria. The Algerian Saharan is a hostile environment characterized by high temperatures, scarcity of water and salinity of water and soil. In these regions, the farmers have for generations cultivated landraces cowpeas which are probably adapted to these particular environments and which may have particular nutritional and functional characteristics. These cowpeas deserve to be known and exploited in breeding and improvement programs. This study aims to determine the nutritional value and functional properties of Saharan cowpea through their chemical composition and the analysis of biochemical variability between accessions taking into consideration the environments of origin. Eighteen cowpea landraces were harvested in an arid region of southern Algeria (Hoggar, Tamanrasset). The seeds composition was evaluated by the determination of certain chemical characteristics such as moisture ash, crude protein, fat, total carbohydrates, and energy value. The antioxidant activity was also evaluated which includes total non-enzymatic antioxidant capacity (CANET) and lipid peroxidation, which were determined by conventional methods. The results showed variability among the accessions studied (p >= 0.05), and that all the landraces had high crude protein and total carbohydrates. The total non-enzymatic antioxidant capacity (CANET) recorded is low, as well as lipid peroxidation. The moisture content, ash content and fat content were also low in these saharan cowpea accessions. The Functional properties of the flour were also evaluated. The water absorption capacity (WAC) varies with an average of 1.17 g/gMS, the oil absorption capacity (OAC) with an average of 0.4 g/gMs, and the swelling index (SI) with an average of 2.63. The accessions NEA7 and NEA13 are the richest in protein and they have the highest nutritional value. We report here for the first time that cowpea seeds grown in the Hoggar region have high biochemical variability and highly acceptable functional characteristics; however, they could be a good source of nutrients.
