Evaluation of extruded corn breakfast cereal enriched with whole peach palm (Bactris gasipaes, Kunth) Flour

Abstract The present study aimed to develop extruded corn breakfast cereal enriched with whole peach palm flour. A 22 central composite rotatable design was used, and the cereal was processed in a ZKS-30 co-rotational twin-screw extruder (Werner and Pfleiderer), followed by its physicochemical, technological and microbiological characterization. The technological analysis revealed higher expansion and lower hardness as well as adequate lightness and water-absorption and water-solubility indices of the breakfast cereal at low moisture and intermediate peach palm flour contents. Moreover, 3.84% ...
