Catalase is widely used in the food industry to remove hydrogen peroxide from milk and cheese products, ensuring they remain fresh and safe for consumption. In the textile industry, it is applied to neutralize hydrogen peroxide after bleaching fabrics, preventing damage and maintaining fabric quality. The cosmetic industry utilizes catalase in products aimed at reducing oxidative stress on hair and skin, promoting healthier appearance. Additionally, it plays a role in biomedical research for studying oxidative stress and aging, as well as in diagnostic kits to detect hydrogen peroxide presence in various samples. In environmental applications, catalase is employed in wastewater treatment to decompose hydrogen peroxide and other harmful peroxides, aiding in pollution control. Its ability to break down hydrogen peroxide efficiently makes it valuable in multiple industrial and scientific applications.
