Textural stabilization of extruded beef jerky analogs (BJA) by using modified starches was studied. From a series of modified starches studied, Frigex W and Instant Pure Flo were identified to show very reduced retrogradation, both in gels and after extrusion. These starches were used as textural stabilizers for BJA, an extruded product obtained from potato granules and ground beef. The partial substitution of potato granules with modified starches, at a level of 5% of the formulation, led to increased moisture sorption capacity of the analogs. After a storage period of 1 mo, the samples that contained modified starch had a degree of swelling with 30% higher and much lower elastic modulus as compared to those that contained only potato starch.
