What it is

Natamycin is a natural antifungal compound produced by the bacterium *Streptomyces natalensis*. It is produced through fermentation, where the bacteria are grown in a controlled environment and then the natamycin is extracted and purified.

Why it's used

Natamycin is used as a preservative to prevent the growth of mold and yeast on the surface of foods. It is commonly found on the surface of cheeses and cured meats, and in some baked goods and fruit juices.

Health notes

In the United States, natamycin is Generally Recognized As Safe (GRAS) by the FDA for use as a food preservative. It is not absorbed by the body when consumed in food, so it is not expected to have any health effects at typical intake levels. International bodies like JECFA and EFSA have also evaluated natamycin and have not set a numerical limit for its acceptable daily intake.

Allergen info

Natamycin is not a major allergen. It is not derived from milk, egg, fish, shellfish, tree nuts, peanuts, wheat, soy, or sesame. It does not contain gluten.
