Gum Arabic (GA)-based gels with different degrees of methacrylation have been prepared.
GA hydrogels show methacrylation degree- and pH-responsive properties.
Curcumin (CUR)-containing GA hydrogels were synthesized and characterized.
Delivery of CUR to simulated fluids depends on the pH and on methacrylation of GA.
GA hydrogels show promising potential for colon-specific drug delivery.
