As a novel biological preservative, ε-polylysine hydrochloride has a series of unique characteristics that make it widely applicable across various fields. Here’s a detailed introduction to its key features:

1. Broad-Spectrum Antimicrobial Activity

ε-Polylysine hydrochloride exhibits significant inhibitory effects on a wide range of bacteria, fungi, and yeasts, including Gram-positive and Gram-negative bacteria. This broad-spectrum antimicrobial property gives it extensive application value in food preservation, personal care products, and other sectors.

2. High Safety

ε-Polylysine hydrochloride is a natural biological preservative produced by microbial fermentation, making it non-toxic and harmless to humans. It can be broken down into lysine in the human body, fully absorbed without producing any toxic side effects. This makes its application in food preservation particularly safe and reliable.

3. Good Stability

ε-Polylysine hydrochloride has excellent thermal stability, retaining its activity even at high temperatures and is resistant to degradation or deactivation. It also adapts well to different pH levels, maintaining its antimicrobial effectiveness in both acidic and neutral environments. This ensures stable antimicrobial performance across various food types and environmental conditions.

4. Ease of Use

ε-Polylysine hydrochloride is easily soluble in water, making it convenient to add to a wide range of foods and personal care products. Its small required dosage does not alter the original taste or quality of food or products, facilitating its application in food processing and personal care product manufacturing.

5. Environmental Friendliness

Compared to traditional chemical preservatives, ε-polylysine hydrochloride is more environmentally friendly. It does not pollute the environment and does not accumulate harmful substances in the human body. This characteristic makes it particularly valuable in today’s context of increasing environmental protection demands.

6. Synergistic Effect with Other Preservatives

ε-Polylysine hydrochloride can work synergistically with other preservatives, such as sodium acetate and potassium sorbate, to enhance overall preservation effectiveness. This synergy enables better antimicrobial performance in more complex environments.

In summary, ε-polylysine hydrochloride offers broad-spectrum antimicrobial activity, high safety, good stability, ease of use, environmental friendliness, and synergistic effects with other preservatives. These features give it vast application potential and market demand in food preservation, personal care products, and other fields.
