Temperature-dependent stability and DPPH scavenging activity of liposomal curcumin at pH 7.0

► The stability and the radical scavenging activity of liposomal curcumin were temperature-dependent. ► Liposomal curcumin degraded more pronouncedly above the phase transition temperature of liposome. ► The liquid crystalline phase of phospholipid bilayer was more beneficial for curcumin to scavenge DPPH. ► Changing the microstructure of encapsulation carrier may be one effective way to control the properties of curcumin.
