Carrageenan, a food enhancer which has been used in processing food, such as in thickening sauces, emulsifying and preserving, and even used in cosmetics, is sourced from a vegetable that grows in the sea—the seaweed. The Philippines is known to have more than 800 species of seaweeds, two of which are used in farms to extract the carrageenan. These are the Eucheuma and Kappaphycus, both locally known as guso, tambalang or kanot-kanot.
