Nisin
Nisin is a polycyclic antibacterial peptide produced by the bacterium Lactococcus lactis that is used as a
food preservative. It is soluble in water and can be effective at levels nearing the parts-per-billion range.
Nisin is a rare example of a “broad-spectrum” bacteriocin effective against many gram-positive
organisms. Therefore, it can act as food preservatives in thermal-treatment food products including
various pasteurised dairy products, canned vegetables, hot baked flour products, etc.
Nisin has been approved as a natural food preservative by more than 60 other countries. In April 1988, it
was recognized as the Generally Regarded as Safe (GRAS) by the U.S. Federal Register.
Key Benefits of Nisin
Extend shelf life
Prevent food spoilage caused by gram-positive bacteria
Shorten food sterilization time
Lower sterilization temperature
No impact on taste and flavor
FAQ
Everything about Nisin
Nisin has a limited shelf life. You need to keep it at cool temperatures or refrigerated until you use it.
Once it is opened, you need to wrap it tightly and store it in the freezer.
Nisin is used in processed cheese, meats, beverages, etc. during production to extend shelf life by
suppressing gram-positive spoilage and pathogenic bacteria. In foods, it is common to use nisin at levels
ranging from 1~25 ppm, depending on the food type and regulatory approval.
safety:
Nisin is listed as a “natural preservative” in chemical dictionaries. It is approved as a natural food
preservative by the Food and Agriculture Organization, WHO and the European Union.Nisin is composed
of 34 amino acid residues. After eating, it is quickly hydrolyzed into amino acids under the physiological
pH conditions of the human body and the action of α-chymotrypsin, which will not change the normal
flora in the human intestines and produce resistance problems like other antibiotics, and will not interact
with other antibiotics. This is a natural food preservative with high efficiency, non-toxicity, safety and no
side effects.
did you know nisin is a rare example of a “broad-spectrum” bacteriocin effective against many gram-positive organisms, including lactic acid bacteria (commonly associated to avoid food spoilage), Listeria monocytogenes (a known pathogen), staphylococcus aureus, bacillus cereus, clostridium botulinum, etc. It is also particularly effective against spores.
