Food additives Preservative Natamycin Natamycin CAS:7681-93-8 is almost odorless white to creamy yellow crystalline powder, the crystalline form of natamycin is very stable. Very low solubility in water and most organic solvents. At room temperature, 1 liter of pure water is soluble about 50mg, which is a low solubility ideal for surface treatment of food. When the pH is below 3 or above 9, the solubility of natamycin is greatly improved, but its stability is also decreased. Natamycin has a slightly higher solubility in some organic solvents, such as n-butanol, propylene glycol, etc., but it is necessary to consider whether these solvents can be used in the food produced. Specification: Natamycin   pharma grade  Natamycin  Feed grade Natamycin   Food grade   * Please refer to Certificate of Analysis for lot specific data.  Application: 1) Natamycin is widely used in cheese, meat products, pastries, fruit juices and other foods around the world. The product is refined from Streptomyces natalensis by deep fermentation and multi-step extraction process. The preparation is a mixture of 50% natamycin and 50% lactose. 2) Natamycin  is anti-mildew agent. It has good anti-mildew effect when it is used on the surface of food exposed to air where mildew is easy to prolifze. The use of fermented cheese can selectively inhibit the reproduction of mold and allow the normal growth and metabolism of bacteria.The product should be stored in a well sealed, no direct sunlight, < 15℃. 3) Natamycin is An antifungal polyene antibiotic that inhibits fungal growth by specifically binding to ergosterol. Unlike nystatin and Philippinomycin, natamycin does not alter membrane permeability. Packing: 25kg/drum
