Natamycin (pimaricin) is a tetraene polyene antibiotic derived from Streptomyces natalensis. The antibiotic is a very strong anti-fungal reagents, It can effectively inhibit the growth of yeast and mold and prevent the aflatoxin formation of filamentous fungi. Compared with other antibacterial ingredients, natamycin has very low toxicity to the cells of mammals.
It can be widely applied to the diseases caused by fungi.
Natamycin can inhibit fungi, it can be applied to cure diseases caused by fungal such as eye drops, gynecological suppository and skin cream.

Advantage
(1)To prolong the shelf life of food treated.
(2)Very low dosage.
(3)Natamycin does not affect the flavor of foods
(4)Natamycin will not penetrate into the food, only be on the surface of food when it was used on the surface of food.
(5)Natamycin can be used under the condition of wide range of pH value
(6)To inhibit the fungi toxin
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
ØNatamycin 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.
ØNatamycin 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.
ØFor agricultural use (bio-pesticide), natamycin is also used tocontrol dry bubble disease caused by Verticillium fungicolain mushroom production facilities.
