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 (FAQ)
Q
What is lysozyme powder and where does it come from?
Lysozyme powder is a naturally occurring enzyme that hydrolyzes microbial cell walls, also known as a cell wall-dissolving enzyme. It is widely found in nature, with hen egg white being the most well-known and abundant source, comprising approximately 3.4%–3.5% of total egg white protein.
Q
What is the enzyme activity level of this lysozyme product?
Our lysozyme powder has a minimum enzyme activity of 2,000 U/mg, with the tested batch achieving 2,300 U/mg. Products produced via bioengineering and ion-exchange resin purification can exceed 20,000 U/mg, meeting pharmaceutical-grade standards.
Q
What are the main applications of lysozyme powder?
Lysozyme powder is used as a natural food preservative due to its bacteriolytic effect. It also serves as a natural anti-infective agent with antibacterial, antiviral, hemostatic, anti-swelling, and analgesic properties. Medically, lysozyme lozenges are commonly used for acute and chronic pharyngitis and oral ulcers.
Q
How should lysozyme powder be stored to maintain its activity?
Lysozyme powder should be stored in a cool, dry place away from light, with a recommended temperature below 0°C. It must be kept at relative humidity below 60% and temperature below 25°C. Improper storage conditions may reduce enzyme activity; in such cases, increasing the dosage during application is advised.
Q
What packaging options are available for lysozyme powder?
For 1kg orders, the product is packed in a double plastic bag with an aluminum foil inner bag, placed in a box. For orders of 10kg, 25kg, or more, it is packed in drums or cartons with two layers of plastic bags inside to ensure product integrity during shipping.
Q
What shipping methods are available and how long does delivery take?
For shipments of 1kg–25kg, we offer EMS, DHL, UPS, and FedEx with door-to-door delivery in 3–7 days. For 25kg–100kg, DHL, FedEx, or air freight is available in 3–7 days. For orders over 100kg, air freight takes 3–7 days (door to airport), while sea freight takes 10–35 days (door to port).
