Curcumin cocrystals using supercritical fluid technology

•Curcumin+N-acetylcysteine cocrystals were prepared by cocrystallization with supercritical solvent technique (CSS).•Cocrystals were produced by solvent-free technique.•By DSC, XRD and FTIR it has been evidenced that the cocrystals were formed.•Cocrystallization provided cocrystals exhibiting a dissolution rate about 2 times higher than pure curcumin crystals.
