With Nisin Preparation

Nisin is a natural antimicrobial peptide produced by the bacterium Lactococcus lactis. It is typically produced through fermentation and then purified for use as a food ingredient. Nisin preparation often includes other ingredients to improve its stability and handling.

Nisin is used as a preservative to inhibit the growth of certain bacteria, yeasts, and molds. This helps extend the shelf life of foods. It is commonly found in dairy products, processed meats, canned goods, and salad dressings.

Nisin is Generally Recognized As Safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use as a food preservative. International bodies like JECFA have evaluated nisin and established acceptable daily intakes. It is considered safe at typical consumption levels and is not associated with significant health concerns.
