Product Introduction

Product Description

Nisin E234 is a polypeptide bacteriocin approved globally as a food preservative. It acts primarily against Gram-positive bacteria, including Listeria monocytogenes, Clostridium botulinum, Staphylococcus aureus, and Bacillus species. Unlike synthetic preservatives, Nisin is naturally derived and biodegradable, making it a preferred solution for natural and minimally processed foods.

We offer high-purity food-grade Nisin that meets international standards (FCC, FAO/WHO, E-number regulations). It is stable under acidic conditions (pH < 5.5), heat-resistant, and compatible with a variety of food matrices. Whether you are producing cooked meat, processed cheese, or ready-to-drink dairy, Nisin helps ensure microbiological safety without compromising quality.
