Curcumin, a yellow pigment present in the spice turmeric (Curcuma longa), has been linked with various bioactivities, but its optimum potential is limited by its lack of dispersibility in aqueous solvents and poor oral bioavailability. Here, we employed a protein-based nanoparticle approach to improve bioactivity and bioavailability. Curcumin was encapsulated with 95.94% efficiency in biodegradable nanoparticulate formulation based on rice bran albumin (RBA). The mean particle diameter and zeta-potential of curcumin-loaded RBA nanoparticles (Cur-RBA-NPs) were 120 nm and -36.3 mV, respectively....
