Chemical Properties:
  1. It is a light yellow powder with strong hygroscopicity and slightly bitter taste. It is a linear polymer of lysine. Shima and H. Sakai discovered during the microbial screening that it is produced by the fermentation of Streptomyces and has a broad-spectrum antibacterial effect. ε-polylysine is polymerized by 25-30 lysine groups, which is relatively stable to pH and heat.
  2. It antibacterial effect is related to the degree of polymerization and environment, and its molecular weight is between 3600-4300. most. At the same time, its hydrolysate is essential lysine, so ε-polylysine is called a nutritional bacteriostatic agent. ε-polylysine has been used in food preservation in the 1980s, but it has not been used for a long time in my country’s Chemicalbook. In 2014, the former Health and Family Planning Commission approved ε-polylysine as a new variety of food additives. As a natural preservative, ε-polylysine has unique application conditions.
  3. It is similar to the benchmark nisin of natural preservatives. It is a polypeptide preservative, and ε-polylysine is more bacteriostatic than nisin. Wider. Most natural preservatives have good bacteriostatic effects on Gram-positive bacteria, but not obvious effects on Gram-negative bacteria such as Escherichia coli. The emergence of ε-polylysine breaks this “hidden rule”. “It also has obvious antibacterial and killing effects on gram-negative bacteria such as Escherichia coli and Arthrobacter products, and the broad-spectrum antibacterial effect is outstanding.
  1. It in food At present, ε-polylysine is widely used in food and beverages, such as cakes, pastries, fast food, butter, salad dressings, beverages, alcohol, meat products, canned food, etc. Refer to the table below for the national standard dosage of different types of food. Food Category Number Food Name Usage 07.0 Baked Food 0.15g/kg 08.03 Cooked Meat Products 0.25g/kg 14.02 Fruit and Vegetable Juice 0.20g/l In addition, ε-polylysine can also be used as food machinery and containers for food processing enterprises Better cleaning and disinfectant
  2. It in cosmetics and daily chemical products During the production, storage and use of cosmetics, they are extremely susceptible to microbial contamination and lead to corruption. The deterioration and mold of cosmetics due to microbial contamination are very harmful to human skin. ε-Polylysine has broad-spectrum antibacterial properties, which can effectively inhibit the growth of various microorganisms and ensure the quality of Chemicalbook products. ε-Polylysine is a polymer of amino acids and a nutritive preservative, so it is more environmentally friendly, safe and efficient. In addition, ε-polylysine is also widely used in daily chemical products such as toothpaste, mouthwash, soap, hand sanitizer, wet wipes, kitchen cleaners, women’s sanitary napkins, and baby diapers.
  3. Itin medicine ε-polylysine is rich in cations, and materials with anions, produce strong electrostatic force, and have good penetration into biological membranes, based on this characteristic ε- Polylysine can be used as a carrier for certain drugs, so it is widely used in medical pharmacy. The polymerization of ε-polylysine and methotrexine (a drug for treating leukemia and tumors) can improve the efficacy of the drug. To study the degree of damage to cell membranes modified by polylysine of different molecular weight by electrical pulses, it was found that the absorption of high molecular weight polylysine on cell membranes would reduce the critical voltage of damage.
