What is natamycin in cheese?
A natural antifungal preservative (E235) applied to the surface of cheeses to prevent mold and yeast growth; it stays near the rind and has minimal penetration or effect on flavor.
Natamycin what is it?
Natamycin (E235) is a polyene antifungal produced by Streptomyces, used in foods to inhibit molds/yeasts and also as a topical antifungal medicine.
How natamycin works?
It binds to ergosterol in fungal cell membranes, disrupting their function and stopping mold and yeast growth; it doesn’t act on bacteria because they lack ergosterol.
Is natamycin an antibiotic?
Yes—it's an antifungal antibiotic (polyene), but in foods it’s used specifically to control molds and yeasts and isn’t active against bacteria.
Why did whole foods ban natamycin?
Whole Foods excludes natamycin under its ingredient standards that avoid certain preservatives/antimicrobial agents; this is a retailer policy choice rather than a regulatory safety ban.
