CHRISIN™ and CHRISIN™ C are standardized powder preparations of nisin which prevents growth of a broad spectrum of Gram-positive microorganisms in food products. It may be used in a variety of cheese and meat products depending on local legislation.
Nisin is highly effective against heat-resistant Clostridium botulinum and other spore-forming Bacillus and Clostridia species. Many of these bacteria are involved in food spoilage and foodborne infections. Nisin is also active against certain non-spore-forming bacteria such as Staphylococcus, Micrococcus and lactic-acid bacteria and restricts growth of Listeria monocytogenes.
Today, nisin use is permitted in over 50 countries, including the EU where it is regulated as a preservative (E234) with restricted use in a number of dairy products, including ripened and processed cheese, clotted cream as well as tapioca and semolina puddings.
