Catalase is widely used in the food industry to remove hydrogen peroxide from milk and cheese products, ensuring they remain safe for consumption. In the textile industry, it is applied to bleach fabrics without damaging the fibers by breaking down hydrogen peroxide after the bleaching process. Additionally, catalase is utilized in contact lens cleaning solutions to neutralize hydrogen peroxide, making the lenses safe to wear. In the medical field, it is employed in diagnostic kits to detect and measure enzyme activity in biological samples. Catalase also plays a role in cosmetic products, where it helps protect the skin from oxidative stress caused by hydrogen peroxide. Its ability to break down harmful peroxides makes it valuable in various industrial and biological applications.
