Product Description
Natamycin is a natural antifungal agent that belongs to the group of polyene macrolide produced by Streptomyces natalensis. Natamycin is a crystallized substance that is colorless, odorless and tasteless. Natamycin is very stable so that it can be widely applied in the food industry for more than 30 years.

Indication and Application
? Natamycin has been used as a natural food preservative for more than 30 years dueto its fungicidal activity against almost all fungi and yeasts. In addition, as natamycin has no antibacterial action, it does not interfere with the food’s natural maturing processes.
? Natamycin can be applied on the surface of cheeses or cured meat productsby dipping the product in an aqueous solution of natamycin, or by spraying the aqueous solution around the product. The most common concentration varies between 1,000 and 2,000 ppm.
? For agricultural use (bio-pesticide), natamycin is also used tocontrol dry bubble disease caused by Verticillium fungicolain mushroom production facilities.
Regulatory Compliances
Following documents and certificates are available as requested;
? EU Drug Master File (DMF) with full impurity profile complies with EMA requirements
? Certificates of KOSHER, HALAL, ISO9001, ISO22000, ISO14001, and OHSAS18001
Availability
? Non-sterile active ingredient of natamycin(micronized/non-micronized) complieswith USP 39 (purity, 90.0%-102.0%), and EC Directive 2008/84/EC (purity, ≥95.0%) is available, respectively.
? 50% end-use formulations of natamycin with different excipients (Glucose, Lactose, Sodium chloride) are also available. Package sizes of the end-sue for mulations are 100g×50 bottles/carton, 500g×10 bottles/carton, and 10 kg/drum, respectively.
Other Information
? Self-life is 24 months from the date of manufacture
? Protect contents from humidity after opening, store in a dry and cool place
? Ultraviolet radiation and oxidants should be avoided
? Use of natamycinis an exception to the prohibition on the use of antibiotics in the food industry, as it has no bacterial action
