Natamycin with Cas 7681-93-8
What is Natamycin?
Natamycin is a polyene macrolide. It binds to sterol compounds on the surface of molds and yeasts, forming pores in the cell membrane and causing bacterial death. Natamycin can broadly inhibit the growth of molds and yeasts and the production of mycotoxins, making it widely used in food preservation.
