• Detailed Description:

  Cas No. :1414-45-5 Introduction
  Nisin is a natural polypeptide food preservative produced through fermentation by Lactococcus lactis. Nisin has good antibacterial
  activity against a wide range of Gram positive bacteria and their spores, especially for heat resistant bacilli, such as Bacillus stearothermophilus,
  Clostridium butyricum and Listeria monocytogenes. It also shows inhibition activity against some Gram negative bacteria under certain conditions.
  Nisin is a natural food preservative which is highly efficient, safe and has no side-effects. Nisin was awarded the Generally Regarded as Safe
  (GRAS) designation in the U.S. Federal Register and is approved as a natural food preservative in the U.S., the FAO/WHO and the E.U.
  
  Advantages
  Extend product shelf-life
  Improve safety a variety of foods by suppressing Gram-positive spoilage and pathogenic bacteria(replace chemical preservatives)
  Cost effective，high efficiency at low dosages
  Enable reduced processing timeshare and temperature
  Useable in fermented products (No effect on bacteria)
  Reduced heat treatment and processing times
  Suppresses post-acidification in cheese
  No apparent cross-resistance related to therapeutic antibiotics
  Stable heating at low pH
  Application
  Typical addition levels of nisin in food applications
  
  Food application Level of nisin (g/kg or g/L)
  Processed cheese 0.2-0.4
  Pasteurized milk and milk products 0.01-0.4
  Pasteurized chilled soups 0.1-0.2

  Direction of Usage: About 5% aqueous solution is prepared firstly with cold boiled water or distilled water (best with pH4 diluted citric acid or acetic acid solution), and then instantly put it into food and stirs well. Or put it directly into food and stirs well.
  Safety
  Nisin is non-toxic, the producer strains of L. lactis are regarded as safe (food-grade); it is not used clinically; there is no apparent cross-resistance in bacteria that may effect antibiotic therapeutics; and it is quickly digested into amino acids by enzymes in human intestines and stomach.
  ADI: 33000 IU/kg (FAO/WHO, 1994)
