Typical source

Bacterial fermentation

Plain-language explanation

E234, also known as Nisin, is a natural preservative produced by the bacterium *Lactococcus lactis* during fermentation, commonly used to prevent spoilage in dairy and canned foods. Since it is derived from a microbial source and not from animals, Nisin is generally considered halal by major certification bodies like JAKIM, MUI, MUIS, ESMA, and HFA. Its halal status is not dependent on the source, as the production process does not involve any haram (forbidden) materials.
