What You Need to Know
Upon cooling below 60°C, kappa-carrageenan undergoes coil-to-helix transition where double helices aggregate into three-dimensional networks, particularly in the presence of potassium or calcium ions which bridge sulfate groups. The gel melts when reheated due to helix dissociation.
Provides smooth, brittle gels ideal for dairy systems where syneresis is desired (like flan weeping) and allows for easy remelting during industrial processing.
