What You Need to Know
Sulfated galactan polymers in kappa-carrageenan undergo coil-to-helix transition upon cooling, with calcium ions bridging sulfate groups (-OSO3-) to form rigid, brittle gels. Syneresis occurs due to tight junction zones.
Enables dairy-free cheese textures without casein, particularly effective in high-fat systems mimicking cheddar or mozzarella.
