Table 1: Proximate composition (%) of whole cowpea flour (WCF), de-hulled defatted cowpea flour (DDCF) and protein isolates (CPIA) and (CPIB) (on dry basis). Means in the same raw with different letters are significantly different (P<0.05). Means ± standard deviation of triplicate an LSD = Least significant differences.
