Film Opacity, Water Vapor Permeability, Water Solubility and Fourier Transform Infrared Radiation (FTIR) of a Biodegradable Film Based on a Duck Feet Gelatin and Polyvinyl Alcohol Blend

Abstract

Abstract- A biodegradable film was prepared from a blend of duck feet gelatin and polyvinyl alcohol (PVA) and was plasticized by glycerol. The effects of using a different ratio of duck feet gelatin to PVA (A=0:100, B=20:80, C=40:60, D=60:40, E=20:80, and F=100:0) on the quality properties were examined, including an analysis of film opacity, water vapor permeability, water solubility and fourier transform infrared radiation (FTIR). The film made from pure gelatin had a low lightness value (95.13) compared to a sample without gelatin that had a lightness value of 96.91. The spectra of the films prepared from blends of duck feet gelatin and PVA (Sample B to D) were similar to those from the pure duck feet gelatin films (Sample F), indicating that there were no major changes in the functional groups of the gelatin produced by interactions between the PVA and the duck feet gelatin. The blended film with the ratio of duck feet gelatin to PVA (sample C=40:60) showed good properties for use as a biodegradable film compared to blended films with other ratios.
