ABSTRACT
The effects of four variable factors such as protein, sorbitol, montmorillonite (MMT) and chitosan on the properties of multi-composite shark catfish skin gelatin films were evaluated based on Response Surface Methodology (RSM). Incorporation of chitosan had positive effect on tensile strength, Young’s Modulus and water vapor transmission rate (p
Keywords: Fish gelatin, SDS-PAGE, chitosan, tensile strength, solubility, barrier property.
