dc.descriptionStarch is a promising alternative to petroleum-based polymers due to its biodegradability and renewable nature. However, its widespread use in non-food applications raises ethical concerns. Mango kernels, a major byproduct of mango processing, represent an abundant yet underutilized starch source. However, conventional starch extraction requires costly purifi cation steps with signifi cant environmental impact. This study explores the devel- opment of extruded biocomposites, using corn starch and mango kernel fl our (MKF) as a more sustainable alternative. The infl uence of lignin, extractives, amylose, and amy- lopectin content on the material properties was assessed. MKF was obtained by removing both tegument and endocarp from the mango kernels, grinding them in a colloidal mill, and fi nally drying the ground kernels. The resulting fl our was blended with corn starch, processed in an internal mixer, and injection-molded. The composites were characterized through mechanical testing, water absorption analysis, colorimetry, and UV absorption assays. Notably, the composite containing ~20% MKF exhibited mechanical properties comparable to commercial polyethylene (PE-PB 208), with a tensile strength of 9.53 MPa and a Young’s modulus of 241.41 MPa. Additionally, MKF enhanced UVA protection. These fi ndings suggest that mango kernel fl our can partially replace starch in the production of injection-molded biopolymers, offering a more sustainable approach to biodegradable plastic development.
