  • Applications
  • Regulations

Fungus in food is a major challenge for global food manufacturers. Natamycin is permitted worldwide as a highly effective antifungal 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 inhibitors.

Natadex™ is natural antifungal agent based on Natamycin produced through fermentation by a strain of “Streptomyces natalensis” and blended with glucose, is specifically produced for antimycotic treatment of processed foods.
