Abstract:
Most of the physicochemical and sensorial properties of the extrudates depend on the extent of the starch degradation. A cereal extrudate has physicochemical properties similar to those of a blend of raw, gelatinized and dextrinized starch. Based on this postulate, models of cereal: oilseed blends were prepared, and different analytical techniques for their characterization were applied. Results revealed that the corn:soy (70:30) extruded sample under study, was similar to moderately dextrinized corn:soy blend obtained in the laboratory. Therefore, it could be used to prepare "papillas" or precooked foods.
