Physico-chemical and mechanical properties of edible zein films from aqueous nanoparticle suspensions

Aim of this work was to investigate physico-chemical and mechanical properties of zein films casted from nanoparticle suspensions in water, with and without plasticizer, and compare it to zein films casted from aqueous ethanol solutions. In order to accomplish that, solubility, moisture absorption, water vapor permeability, tensile strength, elongation at brake, Young’s modulus and FTIR spectra of various zein films were determined.
