F. U. aNutritional ranking of 30 Brazilian genotypes of cowpeas including determination of antioxidant capacity and vitamins. c2012 aThis study aimed to establish a nutritional ranking of 30 genotypes of cowpea (Vigna unguiculata L. Walp). The results showed the proximate composition varies among genotypes in protein (20?30%) and dietary fiber contents (20?35%), in protease inhibitors (2?4 UI/mg protein), lectin (40,000?640,000 UH/kg meal) and essential amino acid levels, in vitro protein digestibility (30?40%) and in the apparent concentration of expressed proteins. The antioxidant capacity varied from EC50 of 9.54?38.7 mg seed extract/mL DPPH and the highest values detected for alpha- and delta-tocopherol were 0.38 mg/g and 1.88 mg/g, respectively. The analysis of a nutritional quality index based on the weighted average content of total protein, dietary fiber, iron, zinc, protease inhibitors and lectins allowed ranking genotypes. In descending order the 5 best genotypes were: BRS-Cauamé> BRS-Tumucumaque> Canapuzinho> BRS-Potengi> BRS-Urubuquara. aBiodiversidade aProteína aVigna Unguiculata aCaupi aMelhoramento genético1 aSOUSA, N.
