Calcium alginate is widely used across various industries due to its biocompatibility and biodegradability. In the medical field, it serves as a wound dressing material, particularly for exuding wounds, owing to its high absorbency, ability to form a gel-like layer that maintains a moist environment to promote healing, and hemostatic properties that aid in stopping bleeding. In the food industry, it functions as a thickening, stabilizing, or gelling agent in products such as sauces, desserts, beverages, ice cream, and jelly to enhance texture and stability. It is also used as an edible coating for vegetables and fruits to extend shelf life. In pharmaceuticals, it acts as a drug delivery system for controlled release of medications. Additionally, in biotechnology, calcium alginate is employed for cell immobilization and encapsulation, supporting processes like fermentation and tissue engineering.
