What it is

Nisin is a natural antimicrobial peptide, a small protein. It is produced by certain strains of the bacterium *Lactococcus lactis* during the fermentation of milk. It is then purified and prepared for use as a food ingredient.

Why it's used

Nisin is used as a preservative to prevent the growth of spoilage bacteria and yeasts. It is particularly effective against Gram-positive bacteria. It is commonly found in dairy products, processed meats, and canned goods.

Health notes

Nisin is Generally Recognized As Safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in food. International bodies like the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have also evaluated nisin and found it safe for consumption. It is not known to cause adverse health effects when consumed at typical levels found in food.

Allergen info

Nisin is derived from milk, but the protein itself is not considered one of the major allergens. The fermentation process breaks down the original milk components.
