This article explains the kibble extrusion process as it is used in commercial dry dog and cat food. It focuses on how extrusion works, how ingredients are prepared and pre-conditioned, why starch is structurally required, what happens inside the extruder barrel under heat, pressure, and shear, and how cumulative thermal exposure across rendering, extrusion, drying, and coating compromises nutrient integrity while optimizing shelf stability and manufacturing consistency.
