Chemical evaluation of multimixes formulated from some local staples for use as complementary foods in Nigeria

Abstract

The nutrient composition of eight multimixesformulated for use as complementary foods fromprocessed soybeans, cowpeas, maize, sorghum, yams,cocoyams, plantains and sweet potatoes were examined. The foods were processed by sprouting, cooking andfermentation. The samples were separately dried andmilled to fine flours. A ratio of 65% cereal, 30%legume and 5% starchy staple (65:30:5) calculated ona protein basis was used to formulate the multimixes. The blends were chemically analyzed using standardprocedures. The mixtures containing soybeans hadhigher protein, lipid, energy, crude fiber and calciumlevels but lower carbohydrate content than thosemixtures without soybean. The protein and energylevels of the multimixes were higher than those ofsome commercial infant foods (Cerelac, Farex andNestrum) in Nigeria but were comparable to that of`soy-ogi'. The multimixes contained fair quantitiesof calcium and phosphorus and an adequate amount ofsome of the essential amino acids. Methionine was themost limiting amino acid in all the mixtures. Blending cowpeas with maize produced a higher proteinscore than blending cowpeas or soybeans with sorghum. The cowpea/maize/sweet potato mixture had the highestprotein score.
