[English name] Nisin
[product molecular formula] c143h228n42o37s7
[product molecular weight] 3348
[product stability]
The stability of nisin is also related to the pH value of the solution
If it is dissolved in skimmed milk with pH = 6
5, the activity will only lose 15% after pasteurization at 85 ℃ for 15 minutes
When it is dissolved in dilute acid with pH = 3, it will still maintain 100% activity after high-pressure sterilization at 121 ℃ for 15 minutes
It has excellent acid resistance and heat resistance

[product properties]
Nisin is a light white or light yellow powder
Nisin, also known as nisin or nisin, is a polypeptide produced by nisin and consists of 34 amino acid residues
Physiological pH condition and & alpha& mdash; Under the action of chymotrypsin, it will be quickly hydrolyzed into amino acids, which will not change the normal flora in human intestine and produce resistance problems such as other antibiotics, nor cross resistance with other antibiotics
It is an efficient, non-toxic, safe and no side effects natural food preservative
It can be widely used in meat products, dairy products, cans, sea food, beverages, fruit juice drinks, liquid eggs and egg products, condiments, brewing technology, baked food, convenience food, aroma based spices, etc

[product bacteriostasis]
Nisin can effectively inhibit many Gram-positive bacteria causing food Fu failure, such as Lactobacillus, Leuconostoc, Micrococcus, Staphylococcus, Listeria, etc
, especially spore producing bacteria such as Bacillus and Clostridium
Generally, spore producing bacteria have strong heat resistance
For example, fresh milk is sterilized at 135 ℃ and ultra-high temperature for 2 seconds
The mortality of non spore bacteria is 100%, that of spore bacteria is 90%, and 10% of spore bacteria cannot be killed
Adding 0
03-0
05g/kg nisin to fresh milk can inhibit the germination and reproduction of spores of Bacillus and Clostridium

[product use]
Nisin can effectively inhibit the vegetative cells and spores of various Gram-positive bacteria such as Bacillus stearothermophilus, Bacillus cereus, Staphylococcus aureus, Listeria, Clostridium botulinum and so on
Adding it into food can greatly reduce the sterilization temperature of food, shorten the sterilization time of food, keep the original nutritional composition, flavor and color of food, and save a lot of energy at the same time
It can be widely used in the anti-corrosion and preservation of meat products, dairy products, plant protein food, canned food, fruit juice beverage and heat-treated closed packaging food
At the same time, it can also be used in the fields of and medical products
