What is Carrageenan?

Carrageenan is a common food additive that is derived from red seaweed. It is used as a thickening agent and stabilizer in a variety of processed foods and beverages. Carrageenan has been used for centuries in traditional cooking, particularly in Ireland, where it was used to make a traditional dessert called carrageen pudding.

Types of Carrageenan

There are three main types of carrageenan: kappa, iota, and lambda. Kappa carrageenan forms a strong gel and is commonly used in dairy products like ice cream and yogurt.

Lambda carrageenan does not gel and is primarily used as a thickener in sauces and dressings.
