The purpose of this study was to investigate the functional properties (thickness; water vapor
permeability (WVP); film microstructure, tensile strength (TS) and biodegradability) of
carboxymethyl cellulose (CMC)/gelatin (gel)/chitosan (chi) biocomposite film as influenced
by different drying temperature (25 and 60 °C). Seven formulations (CMC/gel/chi) prepared
were control (100/0/0), formulations A (80/20/0), B (80/0/20), C (80/10/10), D (60/20/20),
E (60/30/10), and F (60/10/30). Different drying temperature resulted in different time taken
for the film to dry. Results revealed that formulation F was optimal due to its high tensile
strength and low WVP rate which support its biodegradability for both drying conditions. FTIR
assay revealed a strong carboxyl group for CMC, which contributed to high biodegradability
results (85.3 vs. 85.50%) for room vs. oven dried specimens, respectively. Such desirable
characteristics demonstrated that film F holds remarkable potential as edible films material
with enhanced positive impacts on the environment and community.
