This study compared the proximate and mineral composition of extruded samples of African breadfruit flour mixtures with some commercial pasta products (whole wheat spaghetti, enriched macaroni and corn pasta). Sample A composed of African breadfruit, soybean and corn flours while sample B had the mixture of African breadfruit, defatted soybean and corn flours. The flours were blended at ratios 70:25:5 African breadfruit, soybean and corn respectively. The two samples were separately extruded in a Brabender single screw extruder at 21% moisture content, 140ºC barrel temperature and 140 rpm screw speed fitted with 2 mm die diameter. The results show that, the extrudates were significantly high in crude protein (23.90 to 24.50%), fat (3.16 to 7.60%), carbohydrate (54.10 to 54.60%) and energy values (376.06 to 382.80 kcal) than commercial pastas. However, commercial pastas were significantly (p<0.05) high in crude fibre (7.00 to 19.00%) than the extrudates (4.50 to 4.60%). Commercial pasta corn was significantly (p<0.05) high in magnesium (36.00 mg/100 g) but, the extrudates compared favourably in magnesium with whole wheat spaghetti. The extrudates were significantly (p<0.05) high in phosphorus (248.80 to 255.20 mg/100 g), iron (7.20 to 7.60 mg/100 g), zinc (6.80 mg/100 g) and manganese (8.30 to 9.20 mg/100 g) than the commercial pastas. This finding shows that the extrudates could be useful in addressing nutrient inadequacies in areas where it is consumed.
