Post-Extrusion Enzyme Glaze: How Heat-Sensitive Enzymes Survive Kibble Processing Through Spray-On Application

Industry-pattern overview of post-extrusion enzyme glaze application in commercial kibble manufacturing. Most enzymes (protease, lipase, amylase, cellulase) are heat-sensitive and would be inactivated by extrusion at 80-130°C. Post-extrusion spray application after kibble cooling preserves enzyme viability. The framework matters for enzyme label claim accuracy, kibble shelf stability, and consumer understanding of what enzyme-fortified kibble actually delivers.
