Natamycin

Introduction
Natamycin is a naturally antimycotic product which is classified as a polyene macrolide and can be produced during fermentation by the bacterium Streptomyces spp. Natamycin not only inhibits the growth of different moulds and yeasts broadly and high-effectively, but also inhibits the production of their toxin. It can be widely used in food preservation and anti-fungal treatment. Natamycin has no effect on bacteria, so it does not prevent in the natural maturing process of yoghurt, cheese, fresh Ham, sausage, ect.

Advantages
 Effectively inhibits yeast and mold
 Non-toxic, Odorless, Neutral flavor impact
 Extends the shelf life of foods
 Replaces traditional chemical preservatives
 Does not affect useful bacteria
 Cost efficiency due to little dosage but stronger effect
Applications
Natamycin can be added directly to foods by mixing, dipping or spraying. Depending on the application, the amount of natamycin needed varies. To prevent growth of all known food spoilage yeasts and moulds, up to 0.01g/L or 0.04 g/gallon is sufficient.
 Surface Spraying: Block cheese and shredded cheese, Salami and other sausages.
 Direct Addition/Mixing: Yogurt, Sour Cream, Cream cheese and Cottage cheese, Fruit juice and Fruit preparations.
Natamycin also can be applied to grain, silage storage preservation and fruit storage area, it can kill over one hundred kinds the mold may contaminate the grain and feed.
Safty
Natamycin is nontoxic to human bodies, and no any carcinogenesis, mutagenesis or hypersensitivity reaction (HSR) was observed after its use. No normal reistance of moulds and yeasts to natamycin was observed.
 ADI 0~0.3mg/kg (FAO/WHO, 1994)
 Safe to apply on food (FDA, 172.155, 1994)
 LD50 2.73g/kg (experiment with matured male mouse)
