Bacterial fermentation

Plain-language explanation

E235, also known as natamycin, is a natural antifungal preservative produced by the bacterium *Streptomyces natalensis*. It is used to prevent mold growth on foods like cheese and cured meats. Major halal certification bodies generally consider natamycin halal because it is produced through microbial fermentation and not from non-halal animal sources. Its halal status is not dependent on the source, as it is not derived from animals.
