- Introduction
- Applications
Fungus in food is a major challenge for global food manufacturers. Natamycin is permitted worldwide as a highly effective anti-fungal solution. Unlike most antimicrobials, Natamycin is effective at low concentrations and active over a wide pH range (3-9). Because natamycin is used at very low dosage (1-10 ppm), the cost-in-use may be comparable to synthetic preservatives and significantly lower than other natural mold inhibitors.
Natap® Natamycin is a natural occurring antifungal agent produced during fermentation by the bacterium “Streptomyces natalensis”. At Handary, Natap® has been recrystallized to achieve the optimal solubility to effectively eliminate the risk of yeast and mold in food and beverages.
Natap® is up to 200-1,000 times more efficient than chemical preservatives. Natap® natamycin is effective at low concentrations (1-10 mg/kg) and active against most yeast and mold, but has no effect on bacteria, protozoa, or viruses. Food industries that rely on fermentation by bacteria have found natamycin to be very useful because it does not interfere with the fermentation or ripening processes. Most molds are inhibited at concentrations of 0.5 to 6.0 μg/ml, while most yeasts are inhibited at concentrations from 1.0 to 5.0 μg/ml. In addition, Natamycin has no or very little influence on organoleptic qualities and is not known to cause allergic or sensory reactions.
