Technical Data

Purity: 50%, 90%,95%,USP



Food preservative. Ideal result can be achieved by using Natamycin on the exposed surface of the food where

the moulds and yeasts may grow. This is especially useful for cheese manufacture, since the mould growth is

prevented, while the cheese ripening bacteria will grow and metabolize normally. The product should be stored

in dry, cool (not exceeding 15℃ ) places, in original sealed container, and prevent from direct sunlight.


Application standard:
1. U.S.A.: FDA, §172. 155, 2000: Treat (Spray or dip) the surface of the cheese with 200-300mg/kg aqueous solutions.
2. EU: Permitted on the surface of cheese and sausage casings
3. China: GB2760-2001: for cheese, meat and meat products, moon cakes, snacks, raw juice for coating use,

surface of utensils, perishable food, Salad sauce, Fermented wine, etc.
The FAO/WHO Joint Expert Committee on Food Additive confirmed the acceptable daily intake (ADI) if

Natamycin as 0.3mg/KG (total body weight). This was also endorsed by the EU. In China its use is permitted

in the food industry.
