Kojic acid is an organic compound produced by several species of fungi, including Aspergillus oryzae, during the fermentation of rice and other carbohydrate sources. It functions as a tyrosinase inhibitor, effectively preventing enzymatic browning and melanin formation.
In food applications, kojic acid serves as a natural antioxidant and antimicrobial agent that helps preserve color, flavor, and freshness. It is commonly used in Japanese food processing and is gaining broader acceptance in global food manufacturing. Kojic acid is valued for its ability to maintain the natural appearance of foods while providing shelf life extension.
