Introduction

Nisin is a natural preservative produced by the bacterium *Lactococcus lactis* and is classified as a bacteriocin. It is widely used in the food industry for its antimicrobial properties, particularly against a variety of Gram-positive bacteria, including foodborne pathogens and spoilage organisms. Nisin is recognized for its effectiveness in extending the shelf life of certain products while maintaining food safety.

Applications of Nisin

1. Dairy Products: Nisin is commonly used in cheese and other dairy items to inhibit the growth of spoilage bacteria and extend shelf life. It is particularly effective in processed cheeses and cheese spreads.

2. Canned Foods: It is employed in canned foods and processed meats to prevent the growth of harmful bacteria, such as *Clostridium botulinum*, which can cause botulism.

3. Sauces and Dressings: Nisin is added to various sauces, condiments, and salad dressings to improve safety and stability by preventing microbial growth.

4. Baked Goods: In some baked products, nisin can help control mold growth, thus prolonging product freshness.
