Technical information:

Nisin is a natural preservative that is effective against gram-positive bacteria and their spores, and is a bacteriocin obtained by fermenting Lactococcus lactis bacteria.

It is obtained naturally, not chemically synthesized. It is a natural preservative found at very low rates in milk and cheese.

Its molecular formula is C143H228N42O37S7, its molecular weight is 3353 daltons, its color is white.

Nisin was discovered by Rogers in 1928, its first isolation was in 1947, its first use in food was in 1951, and it was included in food preservatives by FAO and WHO in 1969.

It can be stored for a long time at 415°C, as long as it is not exposed to direct sunlight and moisture, without losing its dry nisin feature. It dissolves easily in low pH solutions, deteriorates in solutions above pH=4. Nisin is heat resistant.

Nisin in solution or dry powder form can be used by mixing directly with food. In addition, nisin can be sprayed onto the food surface, immersed in a food solution, or used as a coating factor during food packaging. Nisin has no effect on food taste.

Nisin was first used to extend the shelf life of cheese. Because nisin has the ability to inhibit the growth and effects of gram-positive bacteria and pathogenic bacteria.

Nisin is also used as a protective additive in many sectors because it inhibits the activities of pathogens such as Clostridium botulinum, Staphylococcus aureus, Streptococcus hemolyticus, Listeria monocytogenes, Bacillus cereus, Bacillus sporothermodurans, Brochothrix thermosphacta, Bacillus stearothermophilus and Bacillus subtilis.

Using nisin saves energy in heat-treated foods. Therefore, adding nisin to heat-treated food products not only increases food safety, but also saves energy.

1. Product Information

Nisin E234, a natural polypeptide antibacterial produced by strains of Lactococcus lactis subsp lactis, is a kind of pure natural, efficient and safe peptide active substance extracted by biotechnology. It composed of 34 amino acid residues, White to Creamy-white Powder, now our main specification is 1000IU/mg ~ 10000IU/mg according to your requirements

Nisin has strong inhibitory effect on a variety of Gram-positive bacteria, including food spoilage bacteria and pathogenic bacteria, now it is the only bacteriocin allowed to be used as food additive in the world. When it can be decomposed and digested by chymotrypsin in the digestive tract after entering the human body. It is a safe, non-toxic and efficient natural food preservative, and also a new generation of eco-friendly biological food additives.
