ε-Polylysine Hydrochloride Supplier Quotation,Extend Food Shelf Life

ε-Polylysine hydrochloride is a food additive extracted from *Streptomyces albulus*, a strain of amylase-producing bacteria. It is widely used as a preservative in the food industry and has a significant impact on the shelf life of food. The following is a detailed discussion of the effects of ε-polylysine hydrochloride on food preservation:

Ⅰ.Properties

·Broad Antimicrobial Spectrum: ε-Polylysine hydrochloride exhibits significant inhibitory and bactericidal effects against both Gram-positive and Gram-negative bacteria, yeasts, molds, and viruses. It is especially effective against Gram-negative bacteria, such as *Escherichia coli* and *Salmonella*, which are difficult to inhibit with other natural preservatives.

·High Safety: ε-Polylysine hydrochloride has been approved by the U.S. Food and Drug Administration (FDA) as a safe food preservative (GRAS) and is also approved as a new food additive in countries such as China, demonstrating its high safety profile.

Ⅱ.Impact on Food Shelf Life

1. Extending Shelf Life:

·Adding 0.1 g/kg of ε-polylysine hydrochloride to rice can extend its shelf life from 1 day to 5 days.

·Soaking rice cakes in a 0.5–1 g/kg ε-polylysine hydrochloride alcohol solution for 10 minutes effectively inhibits microbial growth, extending the shelf life of the rice cakes.

·Adding 50–70 mg/kg of ε-polylysine hydrochloride to carbonated beverages can meet the 12-month shelf life requirement.

2. Reducing Preservative Usage:

ε-Polylysine hydrochloride can be used in combination with other preservatives, such as parabens, to reduce the total amount of preservatives used. This allows for effective preservation while minimizing the amount of each individual preservative, thus reducing product costs.

3. Improving Food Quality:

The use of ε-polylysine hydrochloride not only extends the shelf life of food but also improves its quality. For example, adding an appropriate amount of ε-polylysine hydrochloride to wet noodles enhances their quality, making them firmer and improving their texture.

Ⅲ.Applications

ε-Polylysine hydrochloride, as a preservative, can be used in a variety of foods, including fruits, vegetables, legumes, edible fungi, rice and rice products, wheat flour and its products, grain-based products, meat and meat products, seasonings, beverages, etc.

Ⅳ.Usage Precautions

·Moderate Addition: While ε-polylysine hydrochloride has a positive effect on extending food shelf life, excessive use may negatively affect the taste and flavor of food. Therefore, it should be added in appropriate amounts based on the type of food and its shelf life requirements.

·Synergistic Effects with Other Ingredients: In food formulations, ε-polylysine hydrochloride can work synergistically with other preservatives, antioxidants, and ingredients to improve the preservation effect and food quality.

·Storage Conditions: ε-Polylysine hydrochloride should be stored in a well-ventilated, dry, and cool place, away from direct sunlight and high temperatures, to maintain its stability and activity.

As an efficient and safe food preservative, ε-polylysine hydrochloride plays a significant role in extending food shelf life and improving food quality. In the food industry, it should be used appropriately according to the specific type of food and its shelf life requirements to ensure both food safety and quality.
