Abstract Sugar palm (Arenga pinnata) starch is considered an important renewable, biodegradable, and eco-friendly polymer, which is derived from agricultural by-products and residues, with great potential for the development of biocomposite materials. This research was aimed at investigating the development of TPS biocomposites from A.
pinnata palm starch using an extrusion process. Palm starch, glycerol, and stearic acid were extruded in a
twin-screw extruder. Scanning electron microscopy (SEM) analysis of TPS showed that the starch granules were
damaged and gelatinized in the extrusion process. The density of TPS was 1.3695 g/mL, lower than that of palm
starch, and the addition of… More >
