Abstract

The effect of component raw material ratio and extrusion temperature on physico-chemical and mechanical characteristics as well as acceptability of some snack products was investigated. Five different blends of maize and soybeans were extruded at five different temperatures in a total of nine runs, using a computer aided experimental design. Maize was found to enhance colour and expansion while soybeans enhanced textural characteristics of the extrudates. Extrudates of blends had better physico-chemical and textural properties than those of maize or soybean alone. Temperature also enhanced textural and mechanical properties. The sample with optimum characteristics and most acceptable is a 75/25 maize/soybean blend extruded at 150 oC, followed by the 82/18 blend at 168 oC.
