Product Overview
Natamycin, also known as Pimaricin, is a natural antifungal macrolide produced by the bacterium Streptomyces natalensis. It is highly effective against yeast and mold while having no effect on bacteria. Natamycin is approved for use in food products as a surface preservative, particularly for cheese and meat products.
As a natural preservative with a clean label status, natamycin is increasingly preferred by food manufacturers seeking to reduce synthetic chemical preservatives. It works effectively at low concentrations and does not affect the taste or appearance of food products.
