Characteristics

Additive NameNatamycin

TypeIndividual Substance
In plain language

A natural antifungal substance produced by the soil bacterium Streptomyces natalensis. Used on the surface of cheeses and cured meats to prevent mold and yeast growth, extending shelf life without affecting taste or texture. Generally considered safe at permitted levels — it is poorly absorbed by the gut, so systemic exposure is minimal. EFSA and FDA regard it as acceptable for surface use. However, some researchers raise concerns about contributing to antifungal resistance over time.
