Nisin is a natural biologically active antibacterial peptide that is extracted using biotechnology. It is a pure, efficient, and safe peptide active substance that has a strong inhibitory effect on many Gram-positive bacteria, including food spoilage bacteria and pathogenic bacteria. In fact, it is the only bacteriocin that is allowed to be used as a food additive in the world.

Nisin has a broad spectrum of antimicrobial activity and is effective in various food preservation applications. It is widely used in the food industry for its ability to inhibit the growth of spoilage and pathogenic bacteria, thereby extending the shelf life of food products. In this article, we will explore the different applications of nisin in the food industry.

Cheese making is one of the most significant applications of nisin. It is added to the cheese milk during the production process to prevent the growth of undesirable bacteria, such as Listeria monocytogenes and Clostridium botulinum. Nisin also improves the texture and flavor of cheese, and its use has been shown to increase the shelf life of cheese by up to 50%.

Nisin is also effective in canned food, such as meat, fish, and vegetables. It can inhibit the growth of bacteria that cause spoilage and can also prevent the growth of pathogenic bacteria, such as Clostridium botulinum, which can produce toxins that cause severe food poisoning.

In the production of butter, condensed milk, and dry dairy products, nisin can be used to prevent spoilage caused by Gram-positive bacteria. It is particularly effective in extending the shelf life of these products, ensuring that they remain safe for consumption for an extended period.

Nisin is also used in the transportation of milk and meat to prevent the growth of spoilage bacteria during transit. It can be added directly to milk or meat to prevent spoilage and extend the shelf life of these products.

In beverage production, nisin is added to prevent the growth of bacteria that cause spoilage, such as Lactobacillus and Pediococcus. It is also used in brewing and wine production to prevent the growth of spoilage bacteria and improve the quality of the final product.
