Carrageenan is high-molecular-weight polysaccharides that are extracted from Chondrus, Eucheuma and relevant red edible seaweeds. It is a very common food additive. Carrageenan has excellent gelling and thickening properties, which can enhance the texture of food, making it thicker and more elastic. It is frequently used in the food processing industry to produce dairy products, ice cream, sauces, candies, canned foods, etc., to increase product thickness and maintain stability.
