What is E234 - Nisin?
Nisin is a food additive that falls under the category of preservatives. It is labeled as E234 according to the European Union's food additive numbering system. Nisin is derived from the bacterium called Lactococcus lactis, which is commonly found in dairy products.
Nisin is primarily used as a natural antimicrobial agent to inhibit the growth of various bacteria, particularly those responsible for spoiling food or causing foodborne illnesses. It can be effective against both gram-positive and some gram-negative bacteria. The mechanism of action involves disrupting the bacterial cell membrane, leading to cell death.
Food manufacturers often add nisin to dairy products, canned foods, processed meats, and other foods that are susceptible to bacterial contamination. It helps to extend the shelf life of the products and maintain their overall quality.
It is worth mentioning that nisin is considered safe for consumption within the permitted levels set by regulatory authorities such as the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). However, individuals with specific allergies or sensitivities to nisin should avoid consuming foods containing this additive.
In conclusion, nisin (E234) is a natural preservative derived from the bacterium Lactococcus lactis. It is used to inhibit the growth of bacteria in various food products and prolong their shelf life.
