Abstract

Chickpea protein concentrate (CPC) was used in the preparation of edible bio-films. Glycerol and sorbitol, with a different ratios, were used as plasticizing agents. Physico-chemical, microstructure, and mechanical properties of CPC-based biofilms plasticized with glycerol (G100), sorbitol (S100), and a mix of glycerol and sorbitol (G50/S50) were investigated. G100 showed the highest hydrophilicity, solubility, and the lowest thickness compared to S100 and G50/S50. The mechanical properties analysis revealed that (G50/S50) possessed the highest elongation at break and tensile strength. All observed differences were attributed to the interactions between protein and plasticizer which were evaluated by FTIR. In addition, G100, S100, and G50/S50 films demonstrated high antioxidant activity.
