Lysozyme powder is a special role in microbial cell wall hydrolysis enzyme, also called cell walls dissolve enzyme. Widely distributed in nature, including egg qing dynasty of egg white lysozyme total protein 3.4% - 3.5%, is the typical representative of lysis enzymes, but also to know the clear one of lysozyme.
Product Features
As a natural preservative, lysozyme is stable over a range of pH values.
It lyses bacterial cells, especially Gram‑positive bacteria, and exhibits key antibiotic properties.
Produced by bioengineering, pH adjustment and ion‑exchange resin purification, its activity exceeds 20,000 U/mg, meeting pharmaceutical-grade standards.
Functions & Applications
Lysozyme is a non-toxic and side-effect protein, and has a certain bacteriolytic effect, so it can be used as a natural food preservative. It serves as a natural anti-infective agent with bactericidal activity. It provides antibacterial, antiviral, hemostatic, anti-swelling and analgesic effects, and accelerates tissue repair. Lysozyme lozenges are used for acute and chronic pharyngitis, oral ulcers and related conditions.

Frequently Asked Questions
Q
What is Lysozyme powder and how does it function?
Lysozyme powder is a specialized microbial cell wall hydrolysis enzyme. It naturally lyses bacterial cells (especially Gram-positive bacteria) by dissolving their cell walls, functioning as an effective and safe natural antimicrobial agent.
Q
What are the primary applications of Lysozyme?
It is widely used as a non-toxic natural food preservative. In pharmaceutical industries, it is applied as an anti-infective agent providing antibacterial, antiviral, anti-swelling, and hemostatic benefits, and is commonly found in lozenges for pharyngitis and oral ulcers.
Q
What is the typical enzyme activity and quality standard of this product?
The enzyme activity exceeds 20,000 U/mg under pharmaceutical-grade standards. According to our standard specifications, the minimum limit is 2,000 U/mg min, with standard test batches achieving around 2,300 U/mg.
Q
How should Lysozyme powder be stored?
It must be stored in a cool, dry place away from direct light, ideally at a temperature below 0°C. If exposed to high temperature or humidity, enzyme activity may decrease, requiring an increased dosage during application.
Q
What packaging options are available for shipping?
For small quantities (1kg), it is packaged in double plastic bags and aluminum foil bags inside a outer box. Bulk orders of 10kg, 25kg, or more are shipped in drums or cartons with double-layered plastic bags inside.
Q
What are the international shipping and delivery times?
We deliver via express options (EMS, DHL, UPS, FedEx) for weights up to 25kg with a 3-7 day door-to-door delivery. Air cargo and sea freight are available for larger orders above 25kg to 100kg+, taking 3-7 days and 10-35 days respectively.
