Effects of plasticizer concentrations on functional properties of chicken skin gelatin films

M. H. M. Nor, . and N. N. M. Nazmi, . and Norizah Mhd Sarbon, . Effects of plasticizer concentrations on functional properties of chicken skin gelatin films. pp. 1910-1918. ISSN 2231-7546

The aim of this study was to investigate the functional properties of chicken skin gelatin films with varied concentrations of a hydrophilic plasticizer. Gelatin film solutions with different glycerol concentrations A(control) B(5) C(10) D(15) and E(20) were stirred at 45C for 20min and oven dried at 45C. Film characterization determination were included tensile strength (TS) elongation at break (EAB) water vapor permeability (WVP) solubility transparency moisture content Fourier Transform Infrared Spectroscopy (FTIR) and X-ray Diffraction (X-RD). Glycerol added resulted in improvement of TS and WVP properties. Film B (5 glycerol) demonstrated low EAB (106) WVP (0.0175 g.mm/h.m2.k.Pa) and solubility (58.64) but with high TS (3.64 MPa) moisture content (16.0) UV light transmission (0.04) and transparency (0.81) compared to films C D and E. FTIR spectrum analyses demonstrated an aliphatic alcohol group only for Film E (20 glycerol). Hence chicken skin gelatin film at 5 glycerol concentration showed the most promising potential for industrial food processing applications.

Abstract

The aim of this study was to investigate the functional properties of chicken skin gelatin films with varied concentrations of a hydrophilic plasticizer. Gelatin film solutions with different glycerol concentrations A(control) B(5) C(10) D(15) and E(20) were stirred at 45C for 20min and oven dried at 45C. Film characterization determination were included tensile strength (TS) elongation at break (EAB) water vapor permeability (WVP) solubility transparency moisture content Fourier Transform Infrared Spectroscopy (FTIR) and X-ray Diffraction (X-RD). Glycerol added resulted in improvement of TS and WVP properties. Film B (5 glycerol) demonstrated low EAB (106) WVP (0.0175 g.mm/h.m2.k.Pa) and solubility (58.64) but with high TS (3.64 MPa) moisture content (16.0) UV light transmission (0.04) and transparency (0.81) compared to films C D and E. FTIR spectrum analyses demonstrated an aliphatic alcohol group only for Film E (20 glycerol). Hence chicken skin gelatin film at 5 glycerol concentration showed the most promising potential for industrial food processing applications.
