Nisin, a natural antimicrobial peptide produced by certain strains of the bacterium *Lactococcus lactis*, has emerged as a potent tool in food preservation and biotechnology. This peptide consists of 34 amino acid residues with a unique structure that includes several unusual amino acids and a lanthionine ring, which contribute to its stability and antimicrobial activity.
Discovered in the 1920s, nisin gained recognition for its ability to inhibit the growth of a wide range of Gram-positive bacteria, including foodborne pathogens such as *Listeria monocytogenes* and *Staphylococcus aureus*. This selective inhibition makes nisin particularly valuable in the food industry, where it serves as a natural preservative, extending shelf life and enhancing safety without altering the taste, texture, or nutritional value of foods.
Beyond its role in food preservation, nisin has found applications in biotechnology and pharmaceuticals. Its antimicrobial properties make it a promising candidate for combating antibiotic-resistant bacteria, potentially offering new strategies in the fight against infectious diseases. Moreover, research into nisin's interaction with bacterial membranes and its mode of action has provided insights into peptide-based drug design and delivery systems.
Nisin's safety profile, established by regulatory agencies like the FDA and EFSA, further supports its widespread use in food and pharmaceutical applications. As consumer preferences shift towards natural and sustainable ingredients, nisin's status as a naturally occurring peptide derived from a food-grade bacterium enhances its appeal as a safe and effective alternative to synthetic preservatives.
In summary, nisin represents a remarkable example of nature's arsenal against microbial threats, offering versatile solutions in food safety, healthcare, and biotechnology. Its continued exploration and application underscore its potential to address pressing challenges in food security, public health, and sustainable development.

Product name: Sodium erythorbate Synonyms: Sodium D-isoascorbate Chemical Formula: C6H7O6Na.H2O Molecular weight: 216.12 CAS No.: 6381-77-7 Description: Sodium erythorbate is a white or yellow white crystalline powder or granules, odorless, has little salt, the melting point is over 200, it is rather stable when being dry exposed to the air, but in the water solution, when there is air, metal, heat and light, the oxidation will occur. It easily dissolves in water; 16g/100ml at normal temperature, hardly dissolves in ethanol, the PH value of 2% water solution is 5.5-8.0. Which complies with the specifications of GB8273-87, FCC for food additives Net Weight: 25kgs/carton. Uses: Sodium Erythorbate is mainly used in foodstuff industry, used as antioxidant, preservative and coloring agent, broadly used in meat food, fish food, beer, fruit juice, syrup crystal, fruit and vegetable tin, cake, dairy produce, confiture, sherry, pickles, and grease etc. the dosage to the meat foods is 0.5~1.0g/kg. To the frozen fish, the fish should be infused in the 0.1%-0.8% water solution before freezing. The dosage in the beverage such as syrup is 0.01%~0.03%, apple and bechamel tin: 0.15g/kg (dosage of single or together with the VC), luncheon meat, cooked meat powder, cooked front leg pork, cooked ham, the dosage is 0.5g/kg (dosage of single or together with the VC and other sodium salt, counted the VC ), for the peach, apple jam: 2g/kg,for the fruit tin, it is 0.75-1.5g/l, for the nature syrup, it is 0.08-0.11g/l, for the beer, it is 0.03g/l (FAO/WHO(1977). Antioxidation property: the antioxidation property of the Sodium Erythorbate is great larger than the one of cenolate (Sodium VC), has no effects to identify the Vitamin C, but it will not persuade the body to absorb and use the Sodium Erythorbate. The body culls the Sodium Erythorbate and changes it into Vitamin C inside the body. The physiological effects of the Sodium Erythorbate is only the 1/20 of the VC on anti-scurvy, but it is approximately same to the VC on drop blood pressure, diuresis, generating of hepatic glycogen, discharging of pigment, detoxifcation.
