Carrageenan is a natural hydrocolloid extracted from red seaweed, used to thicken, stabilize, and improve texture in food products.
Carrageenan is a polysaccharide obtained from red algae (seaweed) and appears as a white to light-yellow powder. It is widely used in the food industry for its ability to bind water, form gels, and stabilize emulsions, especially in dairy systems.
There are three main types:
-
Kappa carrageenan – strong, brittle gels (with potassium ions)
-
Iota carrageenan – soft, elastic gels (with calcium ions)
-
Lambda carrageenan – thickening only (no gel formation)
Key functional benefits:
-
Improves mouthfeel and creaminess
-
Prevents phase separation
-
Enhances sliceability and structure
-
Reduces syneresis (water release)
Carrageenan works particularly well with milk proteins, making it essential in many dairy and dessert applications.
