Nisin
Specification:Sales base, Lactose
base, Glucose base
Activity:***0 IU, *0,**0IU
Nisin is a polypeptide produced by
Lactococcus lactis and can be digested into amino acids by
a-chymotrypsinin in human intestines and stomach. The use of Nisin
will not affect the normal bacterial community, nor produce the
drug resistance or chiasmatic resistance as it happened when the
antibiotics used.
Effectivity
1. Nisin is a
nonpoisonous and high efficacious food preservative/ anti-microbial
agent.
2. It
possesses anti-microbial activity against a wide range of
Gram-positive bacteria, particularly those that produce spores,
which are the major food spoilage organisms, such as Clostridium
botulinum, Staphylococcus aureus, Streptococcus hemolyticus,
Listeria monocytogenes, Bacillus stearothermophilus, Bacillus
subtilis etc.
3. The use of
Nisin, as a food preservative, can greatly decrease the required
temperature and shorten the time in food heat processing, which
could not only improve the nutritional value, appearance, flavor
and texture of foods, significantly prolong the shelf-life, but
also save energy greatly and lower the product cost.
