Natural Preservative ε-Polylysine Hydrochloride Price

ε-Polylysine hydrochloride is derived from controlled fermentation of Streptomyces diastatochromogenes culture solution, followed by adsorption, desorption, and purification using ion exchange resin. As a natural, safe, and healthy antimicrobial food preservative, it has significant inhibitory effects on Gram-positive and Gram-negative bacteria, yeasts, molds, and other microorganisms.

ε-Polylysine hydrochloride is widely used in food, including seasonings. Specifically, it can be used in fruits, vegetables, beans, edible fungi, rice and its products, wheat flour and its products, coarse grain products, meat and meat products, seasonings, beverages, and various other foods.

As a natural preservative in seasonings, ε-polylysine hydrochloride can effectively extend the shelf life of seasonings, prevent microbial contamination, and thus maintain the quality and taste of the seasonings.

Advantages of application:

·Broad-spectrum antimicrobial activity: It can effectively inhibit a variety of microorganisms, including Gram-positive and Gram-negative bacteria, yeasts, and molds.

·Heat resistance: It does not decompose in high-temperature environments (such as 121℃ for 30 minutes), making it suitable for inclusion in thermal processing along with raw materials.

·High water solubility: Easily soluble in water, with a solubility of at least 500 g/L, making it convenient for use in seasonings.

·Wide pH range of use: It maintains strong antimicrobial activity under pH conditions ranging from 2 to 9, compensating for the low activity of other preservatives in neutral and alkaline conditions.

·Strong synergistic effects: When used in combination with other food additives (such as acetic acid, ethanol, glycine, organic acids, etc.), it can significantly enhance the antimicrobial effect.

·High safety: The acute toxicity test LD50 is 5g/kg, comparable to that of table salt. After ingestion, it degrades into lysine nutrients that are absorbed and utilized by the body.

When using ε-Polylysine hydrochloride as a preservative, it is crucial to adhere to relevant regulations and standards to ensure food safety and legality. Attention should also be paid to its synergistic effects with other food additives to fully exploit its preservative benefits.

As a natural preservative, ε-Polylysine hydrochloride has broad application prospects in seasonings. It not only effectively extends the shelf life of seasonings but also possesses multiple advantages such as heat resistance, high water solubility, a wide pH range of use, strong synergistic effects, and high safety. Therefore, it can be said that ε-Polylysine hydrochloride is a natural preservative in seasonings.
