    Kojic acid

    Kojic acid is a melanin-specific inhibitor that binds to copper ions in cells after entering the skin cells, alters the steric structure of tyrosinase, and prevents the activation of tyrosinase, thereby inhibiting the formation of melanin. Kojic acid active agents have better tyrosinase inhibition than other active agents. It has been formulated into various cosmetics and is a widely used cosmetic active agent. Kojic acid has an antioxidant effect in foods, which inhibits the conversion of sodium nitrite into nitrosamines in foods without affecting the taste, aroma and texture of the food. As a production promoter, it has obvious effects on grain and vegetables.
