Natamycin, also known as pimaricin (labelled preservative E235), is a chemical, antibiotic and antifungal compound used mainly in the dairy industry.
It protects cheese and prevents the growth of fungal species such as yeasts and moulds.Natamycin is derived from bacteria called Streptomyces natalensis and S. chattanoogensis. It is a true fungistatic (it stops the development of microscopic fungi); any type of fungicide (whose purpose is to destroy fungi and spores) is prohibited in food.
Its mechanism of action is to bind to sterols (mainly ergosterol) in the fungal cell membrane instead of permeabilizing the membrane, rather than permeabilising it, which is the mechanism of action of the chemically synthesised preservatives sorbates and benzoates.

Applications
Natamycin - a natural preservative E - 235, is an alternative to sorbate, the minimum introduction of which can significantly reduce the microbiological spoilage of products - cheese, sausages.
Natamycin is a polyene macrolide antifungal agent created by Streptomyces natalensis, Streptomyces chatanoogen and some other Streptomyces species, and is also a fungicidal (antimycotinic) drug in which Natamycin is the active ingredient. Its main purpose is to prevent the growth of mold and yeast on food and beverages.
Natamycin is the only globally recognized antifungal food bio - preservative, safe for the human body, which is capable of highly effective and broad spectrum suppression of mold and yeast growth even at very low concentrations. The use of Natamycin does not change the nutritional value, appearance, taste and structure of food products, nor does it penetrate into sausages or cheese.
Natamycin is currently approved for use as a food preservative in more than 40 countries and is widely used in the production of cheeses, meat products, cakes, fruit juices, sauces, salads and other food products.
Natamycin is classified in the European Directive on food additives as a preservative (E - 235) for use in the surface treatment of dry, ripening sausages and hard, semi-hard and semi-soft cheeses. The level of Natamycin on the surface of sausages at the time of sale should not exceed 1 mg per sq.dm.
