Red algae produces compounds called carrageen, which are thick and jelly-like in composition. These compounds are used as stabilizing and thickening agents in foods and cosmetic products such as mascara. Brown algae contains alginates, which make water-based products thicker and creamier: these edible compounds help fortify yogurt, ice cream and cheese.
