Nisin preservative suppliers


Nisin is a natural antimicrobial peptide produced by certain strains of the bacterium Lactococcus lactis.It is widely used as a food preservative, especially in the preservation of dairy products and processed foods.

Nisin exhibits potent antimicrobial activity against a variety of Gram-positive bacteria, including many foodborne pathogens such as Listeria monocytogenes and Staphylococcus aureus.

Nisin disrupts bacterial cell membranes by forming pores, leading to cell death.This mode of action makes it effective against a broad spectrum of bacteria.

Nisin is commonly used in the preservation of dairy products, such as cheese and yogurt, to inhibit the growth of spoilage and pathogenic bacteria.It is also employed in various processed foods, meat products, canned goods, and beverages.

In dairy products, nisin helps prevent the growth of spoilage and pathogenic bacteria, extending the shelf life of the products.It is particularly useful in inhibiting the growth of Listeria in certain cheese varieties.

Nisin is heat-stable, allowing it to withstand the processing conditions involved in the production of many foods.This makes it suitable for use in heat-processed or pasteurized products.

Nisin can exhibit synergistic effects when used in combination with other antimicrobial agents, allowing for a broader spectrum of microbial control and reducing the risk of microbial resistance.

Nisin has been approved for use as a food preservative in many countries, including the United States, the European Union, and others.It is generally recognized as safe (GRAS) when used within specified limits.

Nisin is a natural product and is generally considered to be biodegradable.Its use aligns with the increasing consumer preference for natural and bio-based preservatives.

While resistance to nisin has been observed in some laboratory settings, its occurrence in foodborne pathogens in real-world conditions is considered rare.The risk of resistance development is lower compared to synthetic antimicrobial agents.

Food products containing nisin as a preservative should comply with labeling regulations.The specific regulations may vary depending on the country or region.

Food manufacturers to adhere to regulatory guidelines, use nisin within recommended concentrations, and monitor its effectiveness to ensure the safety and quality of food products.
