Abstract

Pea nut (Full fat and defatted) and sesame (Full Fat) were used to produce extrudate made from sorghum and corn grits blended with cow pea or chick pea. The blends were prepared to obtain extrudates containing 20% protein. The extruded products were physically and sen­sory evaluated. Trypsin inhibitor and protein digestibility were deter­mined in raw materials and composite blends as well as in the exruded products. The obtained results indicated that, pea-nut and sesame could be used in extruded products as enrichment substance. The formulas con­taining pea-nut, chick pea and yellow maize grits were better than those containing sesame, cow pea and sorghum grits. Extrusion process in­creased protein digestibility and decreased trypsin inhibitor as well as tannin contents.
