Description

Natamycin E235 (Pimaricin) is a natural antifungal preservative made from a pure culture of Streptomyces spp. Streptomyces Natalensis following a carefully controlled fermentation process. It is primarily used as a natural mold and yeast inhibitor. As a food additive, it has an E number of E235.


Natamycin E235 (Pimaricin) is a white to yellow crystalline, tasteless and odorless powder. Its crystalline form is stable. Natamycin has very low solubility in water and most organic solvents. The low solubility in water makes it very suitable for use on food surfaces. Natamycin stays on the surface of food where most molds and yeasts may grow but does not affect the natural fermentation process inside. Natamycin is stable over a wide pH range (3-9). Since the pH of most foods is between pH 4 and pH 7, Natamycin is a widely used food preservative to prevent the presence of yeasts and molds in foods.


Natamycin E235 (Pimaricin) is an antifungal preservative which has broad and effective action. It not only inhibits the growth of different molds and yeasts, but also inhibits the production of their toxin. Commercial Natamycin usually contains 50% of the active substance like Natamycin 50% in Glucose, Natamycin 50% in NaCl, Natamycin 50% in Lactose, Natamycin 95%.
