High Quality Food Preservatives Natamycin CAS 7681-93-8
Natamycin and sodium bezoate each have their own unique applications in food preservation. Natamycin, a natural preservative derived from Streptomyces, primarily targets molds and yeasts, with minimal effects on bacteria. Therefore, it's commonly used in cheese, yogurt, and fermented foods to prevent surface fungal growth, offering the advantages of naturalness, safety, and clean labeling. Sodium bezoate, on the other hand, is a common chemical preservative widely used in carbonated beverages, juices, and condiments. It primarily inhibits the growth of bacteria and some fungi, offering a lower cost and wider application range. From a safety and consumer perspective, natamycin's natural origin better aligns with the "healthy, additive-free" market trend, but its price is relatively high. Sodium bezoate, on the other hand, offers advantages in cost control and large-scale production. Overall, natamycin is more suitable for foods requiring a natural label and mold control, while sodium bezoate is more suitable for products seeking cost-effectiveness and broad antimicrobial efficacy.
