Characterization of fucoxanthin-loaded microspheres composed of cetyl palmitate-based solid lipid core and fish gelatin-gum arabic coacervate shell

► Fucoxanthin-loaded microspheres composed of solid lipid core and coacervate shell ► Solid lipid core made of cetyl palmitate and canola oil ► Fish gelatin-gum arabic complex coacervate shell cross-linked by tannic acid ► The sustained release performance for fucoxanthin was greatly enhanced. ► The storage stability of encapsulated fucoxanthin was considerably prolonged.
