ι-Carrageenan is widely used in the food industry as a gelling, thickening, and stabilizing agent. It is commonly found in dairy products like ice cream, yogurt, and chocolate milk, where it helps improve texture and prevent ingredient separation. It is also used in sauces and bakery products to enhance texture and moisture retention. In meat processing, it is used to enhance water retention and improve the juiciness and tenderness of products like sausages and deli meats. ι-Carrageenan is also utilized in plant-based alternatives, such as vegan cheeses and dairy-free beverages, to mimic the creamy texture of traditional dairy. Beyond food, it has applications in pharmaceuticals, where it acts as a stabilizer in liquid medications and a binder in tablets. Additionally, it is used in cosmetics and personal care products to provide viscosity and improve the consistency of lotions, creams, and toothpaste.
