Description

Nisin E234, also known as nisin, is a polypeptide substance with antibacterial activity extracted from the fermentation product of lactococcus (Lactococcus lactis subsp. lactis) through modern biotechnology. It is composed of 34 amino acid residues. After consumption, it is quickly hydrolyzed into amino acids under the physiological pH conditions of the human body and the action of α-chymotrypsin. It will not change the normal flora in the human intestine and produce resistance problems such as other antibiotics, and will not have cross-resistance with other antibiotics. It is a highly efficient, non-toxic, safe, and side-effect-free natural food preservative.

Nisin can effectively inhibit the nutrient cells and spores of many Gram-positive bacteria that cause food spoilage, such as Bacillus stearothermophilus, Bacillus cereus, Staphylococcus aureus, Listeria, Clostridium botulinum, etc., especially for spore-forming bacteria such as Bacillus and Clostridium.

As a biological food preservative, nisin has been widely used in meat products, beverages, baked products, pickled vegetables, instant rice and flour products, cooked aquatic products, condiments and other fields.

Product Features

NO01

High Security

As a natural preservative, nisin is widely considered safe and non-toxic. Once it enters the human body, it is broken down into a variety of amino acids by proteases in the body, leaving no residue, producing no drug resistance, and having no effect on human probiotics.

NO02

Strong Inhibitory Activity

Nisin effectively inhibits the growth and reproduction of many Gram-positive bacteria that cause food spoilage, especially heat-resistant Bacillus, Clostridium botulinum, etc. It has a strong inhibitory effect on the spores produced.

NO03

High Cost Performance

Nisin has low usage and high cost-effectiveness. It can reduce food sterilization temperature, shorten sterilization time, improve food quality, reduce nutritional damage, and extend storage time.

Application

Nisin: A Highly Efficient, Safe, And Side-effect-free Natural Food Preservative.
