Nisin as a natural antimicrobial peptide

Nisin, a natural antimicrobial peptide produced by Lactococcus lactis, is widely used in food preservation and freshness retention due to its strong inhibitory effect on Gram-positive bacteria (the main cause of food spoilage), high safety (GRAS-certified globally), and compatibility with various food processing technologies. Its applications cover multiple food categories, with targeted mechanisms to extend shelf life and maintain food quality.
