Nisin (E234) – what is it?

Nisin (E234) is a natural food preservative, secreted by Lactococcus lactis bacteria used in the fermentation process. Known for its ability to inhibit the growth of many gram-positive bacteria, nisin is particularly effective against bacteria that cause food spoilage and pathogens such as Listeria monocytogenes.

Because of its naturalness and effectiveness, nisin has gained recognition in the food industry as a safe and preferred additive, especially in the production of organic and natural products. It is also valued for its minimal impact on the taste, smell and color of food products.

Properties of nisin

Nisin is thermo-stable and can be used at high temperatures, making it an ideal additive for thermal preservation processes. It also has a wide range of action, effectively inhibiting bacterial growth without affecting yeast and mold, ensuring its versatility.

Uses of nisin

Nisin’s main applications include dairy products such as cheeses and yogurts, meat products, beverages, preserves and various types of sauces and dressings. It is also used in the pharmaceutical industry as an ingredient in some preparations.

Where to buy nisin?

Nisin can be purchased through suppliers of raw materials to the food industry, as well as at specialized online food additive stores. It is available to both industrial manufacturers and smaller food producers wishing to use safe and natural preservatives.

Nisin and its functions in food

As a preservative, nisin plays a key role in extending the shelf life of food products by inhibiting bacterial growth. As a result, it contributes to food safety, reduces food waste and enables the production of higher quality foods with fewer artificial additives. This is particularly important in the context of the growing demand for natural food products.
