12.7. Carrageenan
Carrageenan is one of the commercially important water-soluble polysaccharides extracted from certain red algae and is widely used in foods, dairy products and pharmaceuticals. There are several varieties of carrageen like kappa and lambda which are used in cooking and baking. Gelatinous extracts of the Chondrus crispus (Irish Moss) seaweed have been used as food additives for hundreds of years. Carrageenan is a vegetarian and vegan alternative to gelatin.
