Abstract

Edible duck feet gelatin (DFG)-based biocomposites with different glycerol (GLY) contents (15%, 25%, and 35% of dried DFG) were prepared. Physicochemical, mechanical, barrier, and heat seal properties of DFG films were characterized and compared as an alternative to bovine gelatin film. Increasing glycerol from 15 to 35% decreased the TS and YM and EB and HS increased, in value of 42.54-7.27 and 1240-157.10MPa and 22.82-50.33% and 42.06-347.15N/m respectively. The water vapor permeability (WVP) and oxygen permeability (OP) of films were increased from 4.78 to 5.6×10^-11gm^-1Pa^-1s^-1 and from 3.97 to 33.99cm³mμ/m² d kPa respectively. GAB model estimations showed monolayer water content of films increased with the increase of plasticizer content. Moisture sorption isotherm modelling exhibited a type II BET classification. Fourier transform infrared (FTIR) spectra showed shifted peak at approximately 1024cm^-1, which was related to glycerol. The results show that the properties of DFG film are suitable for use as an alternative material to bovine gelatin film.
