ABSTRACT

A commercial defatted peanut flour was analyzed for texturization properties in a Wenger X-25 extruder. Extrusion of the flour with addition of sodium stearoyl-2-lactylate resulted in a steady state operation and uniform texturized products. Functional properties of the extrudates such as water retention, hardness, and product integrity upon retorting: were similar to those of textured soy protein. Organoleptic properties of prepared patties (30:70 hydrated textured protein to meat ratio) were not different from the all-meat control for the analyzed sample; cooking losses and shrinkage were lower. Flavor was the most limiting factor for higher levels of incorporation and acceptance. A scanning electron microscopy study showed correlation between microstructure and the properties of the extrudates.
