Nisin E234 is a polycyclic antibacterial peptide produced by the bacterium Lactococcus lactis that is used as a food preservative. Though it’s considered safe, some are convinced it has potentially dangerous health effects.
What Is Nisin E234?
Nisin E234 is used as a preservative in the form of off-white or yellowish powder. It is used during production to prolong the shelf life by minimizing gram-positive spoilage and pathogenic bacteria. Applications include processed beverages, cheese and meats.
Possible Side Effects of Nisin E234
