What is Natamycin in Food? Uses & Safety

Natamycin, a natural antifungal agent derived from the bacterium Streptomyces natalensis, plays a crucial role in food preservation, ensuring the safety and quality of various food products, such as cheese, sausage, baked goods, wine, and yogurt, etc. In this article, we'll explore the multifaceted nature of Natamycin – from its specification and properties to its diverse applications in food preservation, along with safety considerations and proper usage guidelines.

What is Natamycin (E235)?

Natamycin, also known as pimaricin, is a polyene macrolide antibiotic renowned for its potent antifungal properties. It is available in the form of a white to yellowish powder or granule, with a characteristic odor. Natamycin exhibits excellent stability over a wide range of PH and temperature conditions, making it an ideal choice for food preservation applications.

Specification And Properties Of Natamycin

1. Specification: The CAS number of Natamycin is 7681-93-8. And its chemical formula is C33H47O13N. The molecular weight of it is 665.74

2. Appearance: Natamycin presents itself as a white to yellowish powder or granule with a distinct odor.

3. Solubility: Natamycin exhibits limited solubility in water, a characteristic that influences its application in food preservation. While sparingly soluble in water, Natamycin shows better solubility in organic solvents like ethanol and acetone.

4. Antifungal power: One of Natamycin's most notable properties is its powerful antifungal activity. Derived from the bacterium Streptomyces natalensis, Natamycin targets the cell membranes of fungi, disrupting their structure and inhibiting their growth. This mechanism of action makes Natamycin highly effective against a broad spectrum of molds and yeasts commonly encountered in food production and storage.

What Is Natamycin Used For?

Natamycin finds diverse applications in the food industry, thanks to its versatile nature and broad-spectrum antifungal activity. Some of its primary uses include:

►Baked Goods: Natamycin is utilized in the bakery industry to inhibit fungal growth in bread, cakes, and pastries, preserving their texture and taste throughout storage and distribution.

►Meat and Poultry: When applied to the surface of meat and poultry products, Natamycin acts as a protective barrier, preventing mold growth and spoilage, thereby enhancing product quality and safety.

How To Use Natamycin?

Natamycin is typically applied as a surface treatment or incorporated directly into food products during processing. The dosage and application method vary depending on factors such as the type of food product, desired level of protection, and regulatory requirements. Food manufacturers adhere to established guidelines and best practices to ensure the safe and effective use of Natamycin in their products.

Is Natamycin Safe For Humans?

Natamycin is considered safe for consumption when used in accordance with regulatory guidelines and good manufacturing practices. Extensive safety assessments conducted by regulatory authorities, including the FDA and EFSA, have confirmed its safety profile and established acceptable daily intake levels. Natamycin poses no significant health risks to consumers when used as a food additive within specified limits.

What Precautions Should Be Taken When Using Natamycin?

When using Natamycin (E235) as a food preservative, several precautions should be taken to ensure its safe and effective application:

1. Adhere to Approved Dosages: Follow recommended dosage levels provided by regulatory authorities and manufacturers to prevent overuse or underuse of Natamycin. Exceeding recommended levels may compromise food safety and quality.

2. Proper Application Methods: Employ appropriate application methods, such as surface coatings or direct incorporation, based on the specific food product and intended use of Natamycin. Ensure thorough and even distribution of Natamycin to achieve optimal efficacy.

3. Avoid High Temperatures: Natamycin is sensitive to high temperatures, which can degrade its effectiveness. Avoid exposing Natamycin-treated food products to excessive heat during processing, storage, and transportation to preserve its antifungal properties.

4. Storage Conditions: Store Natamycin in a cool, dry place away from direct sunlight and moisture to maintain its stability and potency. Follow storage recommendations provided by manufacturers to prevent degradation and ensure product efficacy.

5. Monitor Shelf Life: Check the expiration date of Natamycin to ensure its viability and efficacy. Dispose of expired or deteriorated Natamycin products according to proper waste disposal guidelines.

6. Labeling Requirements: Clearly label food products containing Natamycin to inform consumers of its presence and comply with regulatory labeling requirements. Provide accurate information regarding Natamycin usage to facilitate informed consumer choices.

7. Monitor for Adverse Reactions: Regularly monitor food products treated with Natamycin for any signs of adverse reactions, such as changes in taste, texture, or appearance. Promptly investigate and address any issues to ensure food safety and consumer satisfaction.

By following these precautions, food manufacturers can effectively utilize Natamycin as a food preservative while ensuring the safety and quality of their products. Additionally, adherence to regulatory guidelines and good manufacturing practices is essential to maintain compliance and consumer confidence in Natamycin-treated foods.

FAQs
