Carrageenan is a polysaccharide extracted from red edible seaweeds. It is widely used as a thickening, gelling, and stabilizing agent in the food industry, as well as in pharmaceuticals and cosmetics. The extraction process typically involves treating the seaweed with an alkaline solution, followed by precipitation and drying. There are three main types of carrageenan, designated as kappa, iota, and lambda, which differ in their chemical structure and properties. Kappa carrageenan forms strong, brittle gels in the presence of potassium ions. Iota carrageenan forms elastic gels and is often used in dairy products to prevent syneresis. Lambda carrageenan does not form gels but acts as a thickening agent.

Carrageenan is recognized as safe by regulatory agencies worldwide, including the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA), when used as a food additive. However, some studies have suggested potential health concerns, particularly regarding its effect on the digestive system. These concerns have led to ongoing research and debate within the scientific community. Despite these discussions, carrageenan remains a common ingredient in a variety of products, including ice cream, yogurt, processed meats, and toothpaste, due to its cost-effectiveness and functional properties. Its versatility allows manufacturers to achieve desired textures and product stability.
