Calcium alginate is widely used in the medical field as a wound dressing material, particularly for exuding wounds, due to its high absorbency and ability to form a gel-like layer that maintains a moist environment, promoting healing. It is also employed in the food industry as a thickening, stabilizing, or gelling agent in products like sauces, desserts, and beverages. In pharmaceuticals, it serves as a drug delivery system, enabling controlled release of medications. Additionally, calcium alginate is utilized in biotechnology for cell immobilization and encapsulation, aiding in processes like fermentation and tissue engineering. Its biocompatibility and biodegradability make it a versatile material across various industries.
