1. Broad-Spectrum Antimicrobial Activity
ε-Polylysine Hydrochloride can inhibit the growth of a wide range of microorganisms, including Gram-positive bacteria, Gram-negative bacteria, yeasts, molds, and some heat-resistant spore-forming bacteria. This broad-spectrum antimicrobial property makes it highly valuable in food preservation, personal care products, and other fields.
2. Thermal Stability
ε-Polylysine Hydrochloride does not degrade in high-temperature environments (e.g., maintaining stability at 121°C for 30 minutes), allowing it to participate in thermal processing along with raw materials. This property makes it advantageous in foods and industrial applications that require high-temperature processing.
3. Wide pH Range Adaptability
ε-Polylysine Hydrochloride exhibits strong bactericidal activity across a pH range of 2 to 9, overcoming the limitations of other preservatives that lose effectiveness in neutral or alkaline conditions. This makes it effective in food and industrial applications with varying pH environments.
4. Synergistic Effect with Other Substances
When used in combination with other food additives (such as vinegar, ethanol, glycine, organic acids, etc.), ε- polylysine hydrochloride shows a synergistic effect, significantly enhancing its ability to eliminate microorganisms. This synergistic property makes it more effective in complex food and industrial systems.
5. High Safety
The acute toxicity test for ε- polylysine hydrochloride shows an LD50 of 5g/kg, comparable to table salt, indicating extremely low toxicity. After ingestion, it degrades into lysine, an essential nutrient, which is absorbed and utilized by the body without any toxic side effects. This ensures its safe and reliable use in food, personal care products, and other applications.
6. Hygroscopicity and Solubility
ε- Polylysine hydrochloride has strong hygroscopic properties and is easily soluble in water, which allows it to mix uniformly with other ingredients during preparation and usage, enhancing the stability and quality of the final product.
7. Health Benefits
Research has shown that ε- polylysine hydrochloride can effectively inhibit enzyme activity and fat absorption, reducing the risk of obesity. This discovery opens up new possibilities for its application in health and functional foods.
ε- Polylysine hydrochloride possesses excellent application properties, including broad-spectrum antimicrobial activity, thermal stability, a wide pH adaptability range, synergistic effects with other substances, high safety, good hygroscopicity and solubility, and potential health benefits. These properties provide it with wide-ranging application prospects in food preservation, personal care products, pharmaceuticals, biotechnology, and more.
