Wet‐milling of soaked, decorticated cowpeas generated large amounts of coarse cell wall material (CWM) and soluble protein (SP). CWM with high water‐holding and swelling capacities contributed to excellent paste hydration and flow properties; high SP and paste viscosity resulted in superior foaming characteristics. In hydrated cowpea meal, the presence of coarse cellular material adversely affected paste hydration and flow characteristics; low SP and viscosity resulted in poor foaming. Wet‐milling of hydrated meal improved viscosity and functionality. Intense dry‐milling increased SP but adversely affected paste viscosity and functionality.
