| Abstract | Biodegradable protein-based films were prepared usingthe commercial gelatin (bovine hide)(CG), giant catfish skin gelatin (GG), soy protein isolates(SPI)incomparison with commercial wrap film (polyvinyl chloride; PVC). Thephysical, chemical and mechanical properties of the resulting films were determined and compared.The molecular weight distributions of the GG had high quantities of ?-chains and ?-components. The GG film had higher mechanical properties [tensile strength: TS 26.42 MPaand elongation at break: EAB 128.25 (%)]but lower thickness (0.0454 mm) than those protein-based films.The PVC film had higher mechanical properties [TS: 44.93 MPa and EAB: 253.71(%)] but lower water vapor permeability [3.37x10-6g?mm?h-1?cm-2?Pa-1], film thickness [0.0103 mm] and film insolubilitythan protein-based films.The filmappearance of protein-based films wassimilar to commercial wrap filmwith uniform transparency. |
