ε-Polylysine Hydrochloride: Advancements in Encapsulation for Controlled Release.

In the realm of modern pharmaceuticals, food science, and various industrial applications, controlled release technologies have become increasingly essential. These technologies allow for the precise release of active compounds over time, enhancing the effectiveness and safety of products ranging from medicines to food additives. ε-Polylysine hydrochloride, a biodegradable and safe polymer, has emerged as a valuable tool in the field of controlled release encapsulation. This 2000-word article explores the advancements in ε-polylysine hydrochloride-based encapsulation and its diverse applications.

Understanding ε-Polylysine Hydrochloride

What is ε-Polylysine?

ε-Polylysine, often abbreviated as ε-PL, is a naturally occurring homopolymer of the amino acid lysine. It is produced by strains of bacteria such as Streptomyces albulus and exhibits unique properties that make it suitable for various applications, particularly in the field of controlled release.

Mechanism of Controlled Release

The controlled release mechanism involving ε-polylysine hydrochloride is primarily based on the degradation of the polymer over time. As ε-polylysine is exposed to environmental conditions, such as moisture and temperature, it gradually breaks down, releasing the encapsulated substance in a controlled manner. This mechanism offers precision in delivering the active compound, ensuring its efficacy and safety.
