Popular questions
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.
What does lysozyme do?
It acts as an antimicrobial preservative by breaking down bacterial cell walls (especially in Gram-positive bacteria), helping prevent spoilage and defects and extending shelf life.
What is a lysozyme?
An enzyme (muramidase), usually derived from hen egg white, approved as food additive E1105 and used to inhibit the growth of certain bacteria in foods.
Where is lysozyme found?
Naturally in egg white, human tears, saliva, and milk; in foods, it’s added to some cheeses and wines as a preservative.
Is lysozyme an enzyme?
Yes—it's an enzyme that hydrolyzes bonds in bacterial peptidoglycan, weakening their cell walls.
What foods contain lysozyme?
Some hard and semi‑hard cheeses and certain wines that use it to control lactic acid bacteria; where required, labels may list “lysozyme (from egg).”
