Food Preservative Natamycin Powder - Natural Antifungal Agent for Food Preservation

Introduction to Natamycin Technology

Natamycin stands as the most effective natural antifungal preservative approved for food applications worldwide. Our high-purity Natamycin Powder is derived through controlled fermentation of Streptomyces natalensis, offering food manufacturers a powerful yet clean-label solution against mold and yeast contamination. This polyene macrolide compound has become indispensable in the food industry, particularly for surface treatment applications where targeted fungal protection is required without compromising product quality or safety.

Product Specifications & Key Characteristics

• Source: Produced by fermentation of Streptomyces natalensis

• Purity: ≥95% natamycin content

• Form: White to cream-colored crystalline powder

• Solubility: Slightly soluble in water (30-100mg/L at 20°C), better in acidic solutions

• pH Stability: Most effective between pH 3-9

• Thermal Stability: Maintains activity at pasteurization temperatures

• Certifications: Complies with FAO/WHO JECFA, FCC, EU (E235) standards

Mechanism of Action & Microbial Spectrum

Natamycin exhibits a unique fungistatic action through:

1. Membrane Binding: Specifically binds to ergosterol in fungal cell membranes

2. Cell Disruption: Creates pores that cause leakage of cellular contents

3. Growth Inhibition: Prevents spore germination and mycelial growth

Effective Against:

• Surface molds (Aspergillus, Penicillium, Fusarium)

• Yeasts (Saccharomyces, Candida, Zygosaccharomyces)

• Mycotoxin-producing fungi

• Food spoilage fungi resistant to other preservatives

Primary Food Applications

• Cheese Surface Treatment: Prevents mold growth on hard/semi-hard cheeses (0.5-2mg/dm²)

• Yogurt & Fermented Dairy: Controls surface contamination

• Butter & Margarine: Extends shelf life (5-10ppm)

• Dairy Powder: Prevents caking from moisture absorption

Meat & Cured Product Applications:

• Dry-Cured Meats: Surface treatment for sausages and hams (1mg/cm²)
