Morphology and size of fibers strongly depended on curcumin contents.
Release kinetics of CUR from zein fibers were investigated by cyclic voltammetry.
Predominant release of CUR from fibers was Fickian diffusion.
First-order and Hixson-Crowell models could well describe the diffusion behavior.
Zein-CUR fibers showed good antimicrobial activity and well controlled release.
