What is Natamycin? Nature's Efficient Mold Guardian

Natamycin (E235) is a polyene macrolide antifungal agent naturally produced during the fermentation of bacteria like Streptomyces natalensis. It was originally isolated from a strain in Natal Province, South Africa, hence its name.Что такое Натамицин сырье порошок?

Its core function is to efficiently and specifically inhibit the growth of mold and yeast, while being ineffective against bacteria and viruses. This makes it ideal for preventing food from becoming moldy or spoiling due to fermentation.¿Qué es el polvo de materia prima de Natamicina?

best Natamycin Powder Usage and Synthesis.

Natamycin has strong inhibitory ability to molds, yeasts and fungi, but has no inhibitory effect on other microorganisms such as bacteria and viruses.O que é o pó de matéria-prima de Natamicina?

Natamycin has a certain resistance to heat treatment, relatively stable in the dry state, can withstand a short period of high temperature (100 ℃); but because it has a cyclic chemical structure, more sensitive to ultraviolet rays, so it is not suitable for contact with sunlight. The anchor stability of Natamycin activity is affected by PH value, temperature, light intensity and oxidizing agents and heavy metals, so the product should avoid contact with oxides and sulfur-hydrogen compounds.Qu'est-ce que la poudre de matière première de Natamycine?

Why Choose Natamycin? Key Advantages Over Traditional Preservatives

Uses of best Natamycin.

Nathamycin is a "polyene macrolide" fungal inhibitor produced by the fermentation of Streptomyces natalis, and is currently the only internationally approved antifungal biofood preservative with high efficiency, broad-spectrum, safety and natural properties.Was ist Natamycin Rohstoff Pulver?

Natamycin relies on its lactone ring structure to interact with sterols on fungal cell membranes to form sterol compounds, thereby destroying the structure of the cytoplasmic membrane. The hydrophilic portion of the macrolide forms water pores in the membrane, impairing cell membrane permeability, which in turn causes the exudation of amino acids, electrolytes and other substances from the fungus, and the death of the fungus.

Because, as a polyene antibiotic natamycin mechanism of action is to bind the sterols on the fungal cell membrane. The cell surface of the animal body lacks sterols, and it is not sensitive to polyene antibiotics. Therefore, natamycin is harmless to human body, and it is difficult to be absorbed by human digestive tract.

No mutagenic, carcinogenic and sensitizing effects. It is a natural antifungal agent, possessing the characteristics of safety, high efficiency, natural and health.

Applications of Natamycin powder

Natamycin is widely used in foods prone to mold:

Cheese: Its classic application. Dipping or spraying onto the surface of hard and semi-hard cheeses creates a protective barrier against surface mold without affecting internal ripening.

Meat Products: Surface treatment for sausages, cured hams, etc., to prevent mold growth.

Baked Goods: Applied to the surface of cakes, fillings, and pie crusts to extend shelf life.

Yogurt & Fermented Drinks: Dropped onto the inside of the lid or directly on the surface to prevent mold where the product contacts air.

Juices & Sauces: Prevents spoilage and gas production caused by yeast contamination.

Safety & Regulations: Is It Safe to Use?

Safety: Natamycin is very poorly absorbed orally (<0.3%) and is excreted in the feces. It is therefore very safe for humans, with no systemic toxicity concerns. It is approved as a food preservative by the WHO, FAO, FDA, EFSA, and authorities in China, among many others.

Regulations & Limits: Maximum usage levels in different foods are strictly regulated (and are typically very low). Always consult the latest regulatory standards for your target market before use.

Frequently Asked Questions.

Q: Is natamycin natural?

A: Yes. It is produced by natural microorganisms (Streptomyces) through fermentation, not chemical synthesis, and is widely recognized as a natural bio-preservative.

Q: Is it harmful to humans?

A: When used within approved applications and dosages, it is very safe. Due to its negligible absorption, it acts locally in the GI tract and is excreted, not entering the bloodstream.

Q: How is natamycin used?

A: It is most commonly applied as an aqueous suspension by dipping, spraying, or brushing onto food surfaces. Due to its low water solubility, it forms an effective protective film. For liquid products, homogenization is needed for even dispersion.
