Product name:Nisin
What is Nisin?
Nisin is a polypeptide formed by Streptococcus lactis, and its appearance is light brown solid powder. And has different solubility at different PH values, and is almost insoluble in alkaline environment. Nisin can be digested and converted into amino acids by protease in digestive tract, and provide necessary nutrients and energy sources for human body. In addition, according to related research, nisin can inhibit the growth and kill most pathogenic bacteria such as Gram-positive bacteria and Bacillus. At present, nisin has been widely used as a pure natural preservative in pharmaceutical manufacturing, health food, convenience food, canned food and other medical and food preservation and storage technologies.
Functions of Nisin:
1. Extend the shelf life: Nisin can inhibit the growth of microorganisms in food, thus extending the shelf life of food.
2. Maintain food quality: Frozen food often needs to add some preservatives to maintain food quality during freezing, but these preservatives have a certain impact on human health. Nisin is a natural antibacterial agent, which will not have a negative impact on human health and can effectively maintain the quality of food.
3. Improve the taste: Nisin can inhibit the growth of yeast and mold in food, thus reducing the possibility of food odor and deterioration and improving the taste of food.
