To develop and evaluate biodegradable composite films synthesized from bitter cassava starch and coconut mesocarp cellulose as sustainable packaging alternatives.
Formulated biopolymer films via casting using bitter cassava (Manihot esculenta) starch, glycerol plasticizer, Tween 80 emulsifier, and coconut mesocarp cellulose at concentrations of 6%, 8%, and 10%.
Characterized chemical functional groups, physical microstructure, moisture content, and water absorption capacity across the different formulations.
FTIR spectroscopy confirmed characteristic functional groups (-OH, C-H, C=O, and C-O-C), validating the chemical purity and structural integrity of the starch and cellulose components.
Varying cellulose content significantly modified material microstructure, producing film thicknesses of 0.49 to 0.56 mm, moisture contents of 6.46% to 8.01%, and water absorption rates of 67.7% to 109.5%, with the 8% (0.4 g) cellulose formulation achieving optimal results.
