Nisin is a natural bactericidal ingredient produced by fermentation of Lactococcus lactis subsp. lactis (non-GMO). Approved in the EU as E-234 and effective mainly against Gram-positive bacteria such as Clostridium spores, Staphylococcus aureus, Listeria monocytogenes and Bacillus. Not effective against Gram-negative bacteria, yeasts or molds.
Nisin supports multi-hurdle preservation by reducing Gram-positive pathogen risk, particularly in heat-treated and acidic foods. It is not intended for Gram-negative bacteria, yeasts or molds.
Reference range: 25–500 mg/kg or mg/L. Final level depends on product/process. Please contact our team.
