Hydrocolloid-Driven Structure-Property Relationships and pH-Responsive Release of C-Phycocyanin from Alginate-Chitosan Composite Hydrogel Beads
This study demonstrates that alginate–carrageenan–chitosan composite hydrogel beads significantly enhance the encapsulation efficiency and storage stability of C-phycocyanin while effectively controlling its pH-responsive release under simulated gastrointestinal conditions, with release kinetics best described by the Korsmeyer-Peppas model.
