Nisin (E234) — Natural Food Preservative

What is Nisin?
Nisin is a natural, toxicologically safe, antibacterial food preservative, derived from vegetable sources. It is a polypeptide produced by certain strains of the food-grade lactic acid bacterium Lactococcus lactis subsp. Lactis during fermentation. Nisin is effective against a wide range of Gram-positive bacteria and is particularly effective against spore-forming bacteria, while showing no activity against yeasts and moulds.

Approved by JECFA (Joint FAO/WHO Expert Committee on Food Additives) since 1969 as food additive E234, Nisin is currently permitted for use in over 50 countries.

Mode of Action
Nisin forms a complex with Lipid II and inserts into the cytoplasmic membrane of bacteria, forming pores that cause efflux of essential cellular components, leading to inhibition or death of bacteria.

Stability
Nisin retains full activity for over two years when stored dry in the dark below 25°C. Best thermal stability at pH 3.0–3.5 (autoclaving 121°C/15min, <10% loss).
