The properties of binary blend films (100/0, 75/25, 50/50, 25/75 and 0/100) based on gelatin (GEL) and polysaccharides exhibiting emulsifying activity: gum Arabic (GAR), methylcellulose (MC), octenyl succinic anhydride modified starch (OSA) and water soluble soy polysaccharides (WSSP) were investigated. The micrographs showed that among the polysaccharides only MC was not miscible with GEL. Consequently, GEL/MC blend films were non-homogenous, opaque and usceptible to dissolution. The dynamic light scattering (DLS), microscopic, optical and mechanical measurements revealed that the polymer incompatibility tended to be the highest at mass ratio GEL:MC=50:50. As verified by Fourier-transform infrared (FTIR) spectroscopy, OSA and WSSP interacted stronger with GEL than MC and GAR. Among the blend films, the MC-containing films had the most crystalline structure. Substituting part of GAR, MC and WSSP for GEL decreased the water vapor permeability of the blend films. Apart from MC, the increasing level of polysaccharides in the films resulted in gradual decrease of mechanical parameters. The most stretchable film was achieved by mixing of GEL with OSA at ratio of 25/75. This film, however, exhibited noticeable symptoms of recrystalization during storage.
