Short Description:

Natamycin CAS 7681-93-8

Natamycin, also known as horse horse mold or swimming mold, was first isolated from Streptomyces natalis in 1955 and its activity is much better than that of sorbic acid. In June 1982, the US FDA officially approved natamycin as a food preservative and classified it as a GRAS product. Natamycin is a highly effective inhibitor of mold, yeast, and fungi used to inhibit mold, yeast, and fungi in food. It is safe, reliable, and does not affect product flavor. It is widely used in foods such as cheese, meat products, pastries, and juices worldwide. This product is refined by deep fermentation and multi-step extraction of streptomycin, and its formulation is made by mixing 50% natamycin and 50% lactose.

Natamycin has a strong inhibitory effect on molds, yeasts, and fungi, but has no inhibitory effect on other microorganisms such as bacteria and viruses. Natamycin has a certain ability to resist heat treatment, is relatively stable in a dry state, and can withstand short-term high temperatures (100 ℃); However, due to its cyclic chemical structure and sensitivity to ultraviolet radiation, it is not suitable for contact with sunlight. The anchor stability of natamycin activity is affected by pH value, temperature, light intensity, oxidants, and heavy metals, so the product should avoid contact with oxides and sulfur compounds.
