Natamycin 95%

Natamycin is a natural antimycotic product which is classified as a polyene macrolide and can be produced during fermentation by the bacterium Streptomyces spp. Natamycin not only inhibits the growth of different moulds and yeasts broadly and high-effectively, but also inhibits the production of their toxin. It can be widely used in food preservation and anti-fungal treatment. Natamycin has no effect on bacteria, so it does not prevent in the natural maturing process of yoghurt, cheese, fresh Ham, sausage, etc.
