What it is

Nisin preparation is a natural antimicrobial substance produced by certain strains of the bacterium Lactococcus lactis. It is typically produced through fermentation and then purified. Nisin works by disrupting the cell membranes of target bacteria, preventing their growth.

Why it's used

Manufacturers add nisin preparation as a preservative to prevent the growth of spoilage bacteria, particularly in heat-treated foods. It is commonly found in dairy products, canned goods, and processed meats.

Health notes

Nisin preparation is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use as a food preservative. It is not absorbed by the body and is broken down into amino acids. International bodies like JECFA and EFSA have evaluated nisin and found it safe for its intended use. There are no widespread health controversies associated with its consumption at typical levels.

Allergen info

Nisin is produced by bacteria and is not derived from any of the nine major allergens. It does not contain gluten.
