Natamycin is a natural antifungal compound produced by the fermentation of Streptomyces. It belongs to the polyene macrolides, which can widely and effectively inhibit the growth of various molds and yeasts, as well as inhibit the production of mycotoxins. It can be widely used in food preservation and antifungal treatment. Natamycin has no inhibitory effect on bacteria, so it does not affect the natural ripening process of yogurt, cheese, raw ham, dry sausage.
