Curcumin (CUR; 0, 0.005, 0.01, 0.02 %) was loaded into binary 75/25 blend films based on polysaccharides
(carboxymethyl cellulose (CMC), gum Arabic (GAR), octenyl succinic anhydride modified starch (OSA), water-
soluble soy polysaccharides (WSSP)) and gelatin (GEL). The GAR-based system was the least rough and,
consequently, the most transparent of the films. An opposite result was found for the WSSP-based film. Despite
the phase separation, the CMC75/GEL25 film exhibited excellent mechanical strength and stiffness. CUR
improved the UV/VIS light-barrier characteristics of the films, but did not affect most of other physiochemical
properties. X-ray diffractograms revealed that CUR provoked the rearrangement of the triple helical structure of
GEL. As highly erodible, the CMC75/GEL25 carrier ensured the fastest and the most complete release of CUR.
The OSA75/GEL25 system exhibited an opposite behavior. The kinetic profiles of the antiradical activity of the
films did not reflect CUR release. A comparison of 2,2-diphenyl-1-picrylhydrazyl (DPPH*) scavenging on the
plateau revealed that the CUR-supplemented films had quite comparable antiradical potential. The CMC75/
GEL25 system exhibited the highest colorimetric stability, likely as a result of complete encapsulation of CUR in
the GEL-rich microspheres. Weak symptoms of physical aging (enthalpy relaxation) were found in the films.
