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.
