Catalase is widely used in the food industry to remove hydrogen peroxide from milk prior to cheese production, ensuring better quality and safety of dairy products. It is also applied in the textile industry to eliminate hydrogen peroxide after bleaching processes, preventing damage to fabrics and dyes. In the contact lens cleaning systems, catalase breaks down hydrogen peroxide into water and oxygen, making the solution safe for eye contact. Additionally, it is used in biochemical research and diagnostic kits to detect hydrogen peroxide in various assays. Due to its antioxidant properties, catalase is explored in cosmetics and pharmaceuticals for protecting cells from oxidative stress and aging.
