Nisin (E234)

Nisin

Nisin is a natural bacteriocin peptide produced by fermentation of Lactococcus lactis subsp. lactis using dairy-based media, used as a potent antimicrobial preservative (E234) specifically targeting Gram-positive bacteria including Listeria, Clostridium, and Staphylococcus species. In the food industry, it provides targeted pathogen control, clean label preservation, and heat stability ideal for dairy, meat, and canned products extending shelf life without impacting sensory qualities.

Food Industry Applications

• Dairy products: Prevents Listeria and Clostridia growth in cheese, processed cheese, yogurt, cream desserts, and pasteurized milk maintaining safety during refrigerated storage.

• Canned and processed foods: Controls sporeformers and pathogens in soups, vegetables, meat products, and ready meals preventing blowing and spoilage during heat processing.

• Meat and poultry: Inhibits Listeria monocytogenes in sliced meats, sausages, pâtés, and ready-to-eat poultry products extending shelf life under modified atmosphere packaging.

• Beverages: Stabilizes fruit juices, carbonated drinks, and alcoholic beverages against spoilage bacteria without affecting yeast fermentation or flavor profile.

• Bakery fillings: Protects custard fillings, fruit pies, and cream cakes from bacterial contamination while maintaining fresh texture and appearance.

Other Industry Applications

In animal feed, prevents bacterial spoilage; in cosmetics, provides antimicrobial preservation; in personal care, stabilizes formulations; in dentistry, controls oral bacteria; in water treatment, disinfects process water; in the brewing industry, prevents beer spoilage.
