Natamycin Added To Maintain Freshness

Natamycin is a natural antifungal compound produced by the bacterium *Streptomyces natalensis*. It is produced through fermentation, a process where microorganisms are grown under controlled conditions to yield a desired substance. The resulting compound is then purified for use in food.

Natamycin is primarily used as a preservative to prevent the growth of mold and yeast on the surface of foods. It is commonly found on cheeses, processed meats, and baked goods like crackers and biscotti, helping to extend their shelf life and maintain freshness.

In the United States, natamycin is Generally Recognized As Safe (GRAS) by the FDA for use as a food preservative. It is poorly absorbed by the body when consumed, meaning it largely passes through the digestive system without being absorbed into the bloodstream. International bodies like the European Food Safety Authority (EFSA) have also evaluated natamycin, and it is approved for use in many countries.
