Abstract
Spent hens: a poultry by-product, have little marketplace and their disposal methods are infeasible so to figure out alternatives which is environment friendly. In this study, proteins were extracted from spent hen by alkali aided extraction method with high recovery yield and purity. These proteins were further modified using glycerol, chitosan and bentonite to increase the value of spent hen proteins. The objective of this work was the improvement of mechanical strength of the protein derived bionanocomposites films. The improvement in physical properties was observed by Transmission electron microscopy (TEM), Dynamic mechanical analysis (DMA), Differential scanning calorimetry (DSC) and Attenuated total reflectance- Fourier transform infrared spectroscopy (ATR- FTIR) . The study revealed, 3% chitosan enhance the mechanical strength of derived films which can be further improved by bentonite addition and it increased to 11.37 MPa that is contributed due to the strong interaction and hydrogen bonding developed between filler and matrix. The thermal stability and water vapor permeability also improved due to the small amount of chitosan and bentonite. The results showed films have the ability to used for food packaging applications.
