Description
Natamycin, also known as pimaricin and sometimes sold as Natacyn, Natamycin is a naturally occurring antifungal agent produced during fermentation by the bacterium Streptomyces natalensis, commonly found in soil.
Natamycin has a very low solubility in water; however, natamycin is effective at very low levels. Its minimum inhibitory concentration is less than 10 ppm for most molds.

Appltcatton
Natamycin has been used for decades in the food industry as a hurdle to fungal outgrowth in dairy products, meats, and other
foods. Potential advantages for the usage of natamycin might include the replacement of traditional chemical preservatives, a neutral flavor impact, and less dependence on pH for efficacy, as is common with chemical preservatives.
