2000
Punia, Komal Preet Darshan
Four cultivars of brown cowpea (Vigna unguiculata. L. Walp) were analysed for their proximate composition, phytic acid, polyphenols and protein and starch digestibility (in vitro). Crude protein values ranged from 20.07 to 24.60%. Ether extract and crude fiber contents varied from 1.77 to 1.96% and 4.27 to 4.95%, respectively. All the four cowpea varieties differed significantly for their starch content which ranged from 46.84 to 53.63%. Antinutrients, phytic acid and polyphenols, showed significant variations among the varieties. In vitro digestibility of protein and starch of grains had a narrow variation. The variety CS-46 containing minimum amount of antinutritional factors had the highest protein digestibility.
