Abstract: Thermoplastic starch materials and methods of making the same are provided. The methods involve mixing a starch material, plasticizer and water in a low-shear mixer under conditions that will result in substantial gelatinization of the starch material. The melt formed within the mixer is discharged into an extruder for final processing. The methods prevent degradation of the starch material thereby resulting in the formation of a thermoplastic starch material having high strength, due at least in part to the preservation of the molecular weight characteristics of the starch, and improved elasticity due the ability to use higher water contents than conventional processes.
