Nisin (E234)

Nisin Nisin is a natural bacteriocin peptide produced by fermentation of Lactococcus lactis subsp. lactis using dairy-based media, used as a potent antimicrobial preservative (E234) specifically targeting Gram-positive bacteria including Listeria, Clostridium, and Staphylococcus species. In the food industry, it provides targeted pathogen control, clean label preservation, and heat stability ideal for dairy, meat, and canned products extending shelf life without impacting sensory qualities.
