High-purity Nisin Powder

Nisin has significant advantages in the food processing industry, which are mainly reflected in the following aspects:

1. Strong and Broad-Spectrum Antibacterial Activity

Nisin inhibits most Gram-positive bacteria and strongly suppresses the spores of Bacillus species. It effectively inhibits various bacteria that cause food spoilage, such as Clostridium botulinum, Staphylococcus aureus, Streptococcus hemolyticus, Listeria monocytogenes, and Geobacillus stearothermophilus.

2. High Selectivity and Safety

Nisin mainly targets certain bacterial species, with minimal impact on the normal human microbiota and other beneficial bacteria, ensuring good selectivity. It is a non-toxic natural preservative that quickly hydrolyzes into amino acids under physiological pH conditions and α-chymotrypsin in the human body, without altering the normal gut flora or causing resistance or cross-resistance issues commonly associated with other antibiotics.

3. Strong Stability

Nisin exhibits good thermal and pH stability, maintaining its antibacterial activity over a wide range of temperatures and pH levels. For example, it shows excellent heat resistance at pH 2, and although its heat resistance decreases at pH levels above 5, its overall stability remains good.

4. Wide Application

Nisin is widely used in various foods, including dairy products, canned goods, fish products, and alcoholic beverages. With ongoing research and increasing market demand, its application is gradually expanding to other food categories such as meat products, baked goods, and fruit juice beverages.

5. Promising Market Prospects

As an efficient, safe, and non-toxic natural biopreservative, nisin's global market demand is steadily increasing. With the growing emphasis on healthy eating and stricter regulations on additives, nisin is poised to replace traditional chemical preservatives and become a mainstream product in the food preservative market.

6. Rapid Industry Development

China's nisin industry has seen substantial improvements in strain selection, isolation and purification, product quality, application research, and fermentation processes. A number of competitive companies have emerged domestically, such as Hebei Shengxue Dacheng Pharmaceutical Co. China is gradually becoming the world's largest producer and consumer of nisin.

In conclusion, nisin exhibits remarkable antibacterial properties, selectivity, safety, stability, and wide application prospects in the food processing industry, alongside significant potential for industry development.
