About Nisin:
Molecular Weight: Approximately 3,354 Daltons for nisin A, one of the most commonly studied and used variants.
Solubility in Organic Solvents: It has limited solubility in most organic solvents, reflecting its polypeptide nature.
Thermal Stability: Nisin is relatively heat stable, especially at acidic pH levels, which allows it to maintain its antimicrobial activity during food processing operations like pasteurization.
pH Sensitivity: Its activity is significantly influenced by pH, with optimal antimicrobial activity observed in acidic conditions (pH 2-5). Its effectiveness diminishes in neutral to alkaline conditions.
Enzymatic Degradation: Nisin can be degraded by proteolytic enzymes, which may limit its activity in certain applications but also helps ensure that it does not accumulate in the environment or the human body.
Application of Nisin:
Food Industry:
Dairy Products: Nisin is extensively used in the dairy industry to extend the shelf life of products such as cheese, processed cheese, and dairy-based desserts by inhibiting spoilage and pathogenic bacteria including Listeria monocytogenes, a notorious foodborne pathogen.
Canned Foods: It is used in canned foods to prevent the outgrowth of spore-forming bacteria.
Beverages: Nisin can be added to certain beverages, including pasteurized liquid egg products, to inhibit the growth of spoilage bacteria.
Meat Products: It is applied in meat products to inhibit the growth of Listeria monocytogenes and other bacteria that can cause spoilage, thereby extending the product's shelf life and enhancing food safety.
High Moisture Foods: Nisin is effective in high moisture foods where the risk of bacterial growth is higher. Its use helps in controlling the microbial quality of these products.
Pharmaceutical Industry:
Antibacterial Agent: Due to its potent antibacterial properties, nisin is being researched for use as a natural preservative in pharmaceuticals and as a potential treatment for infections caused by antibiotic-resistant bacteria.
Dental Health Products: Nisin has been explored for use in dental health products, such as mouthwash and toothpaste, to control oral bacteria that can cause dental plaque, cavities, and gum disease.
Wound Care: There is ongoing research into the application of nisin in wound care products, such as creams and dressings, for its ability to inhibit the growth of skin infections caused by bacteria.
