- Introduction
- Applications
The growth of unwanted yeasts and molds in cheeses may make them unfit for human consumption. Therefore, during ripening, cheeses can be protected against the development of fungi by coating their surfaces with a protective layer.
Natalac™ Natamycin is a naturally occurring antifungal agent produced during fermentation by the bacterium “Streptomyces natalensis”. It contains min. 50% natamycin which is blended with lactose. Natalac™ is effectively used to eliminate the risk of yeast and molds during cheese ripening. It may either be added to the brine, used as an aqueous suspension for dipping cheeses or added to polyvinyl acetate to coat cheeses.
*Natamycin, at a concentration considerably lower than other known fungicides, destroys both mold hyphae and spores. The inhibitory concentration of sorbate is as high as 300 mg/dm² of cheese surface, while the permissible concentration of natamycin is only 2 mg/dm². Sorbate diffuses into cheese and affects its organoleptic properties, whereas the migration of natamycin is negligent, and when used in polyvinyl acetate, it remains on a surface of the cheese.
