Curcumin/xanthan-galactomannan hydrogels: Rheological analysis and biocompatibility

► A xanthan-galactomannan hydrogel was tested as a potential matrix for curcumin delivery. ► Curcumin did not alter the viscoelastic characteristics of the hydrogel. ► The curcumin/hydrogel system exhibited biocompatibility in chick embryo chorioallantoic membrane assays.
