What it is

Nisin Preparation Salt is a mixture of nisin, a natural antimicrobial peptide, and salt. Nisin is produced by the bacterium Lactococcus lactis during the fermentation of milk. The preparation is used as a food preservative.

Why it's used

Manufacturers add nisin to foods to prevent the growth of spoilage bacteria and extend shelf life. It is particularly effective against certain types of bacteria like Listeria monocytogenes. It is often found in dairy products, processed meats, and canned goods.

Health notes

Nisin is generally recognized as safe (GRAS) by the FDA for use as an antimicrobial agent in food. It has been evaluated by international bodies like JECFA, which has established its safety. Nisin is not absorbed well by the body and is broken down into amino acids, its basic building blocks.

Allergen info

Nisin is derived from milk but is a protein produced by bacteria, not a direct milk allergen. It is not considered a major allergen.
