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 derived primarily from hen egg white, where it accounts for 3.4%–3.5% of total protein. It functions as a microbial cell wall hydrolysis enzyme, capable of breaking down bacterial cell walls, and is widely distributed in nature.
Q
What is the enzyme activity of your lysozyme powder?
Our lysozyme powder has a tested activity of 2,300 U/mg, exceeding the minimum requirement of 2,000 U/mg. Products produced via bioengineering processes can achieve activity levels exceeding 20,000 U/mg, meeting pharmaceutical-grade standards.
Q
What are the main applications of lysozyme powder?
Lysozyme powder is widely used as a natural food preservative, a pharmaceutical anti-infective agent, and an ingredient in health products. It is incorporated into lozenges for treating acute and chronic pharyngitis and oral ulcers. Its antibacterial, antiviral, hemostatic, anti-swelling, and analgesic properties also support tissue repair.
Q
How should lysozyme powder be stored to maintain its activity?
Lysozyme powder should be stored in a cool, dry, and light-protected environment at temperatures below 0°C, with relative humidity kept below 60%. Improper or prolonged storage may reduce enzyme activity. If stored under suboptimal conditions, it is recommended to increase the application dosage accordingly.
Q
What packaging options are available for lysozyme powder?
For small quantities (1kg), we offer individual bags with double plastic inner bags and aluminum foil packaging inside a protective outer box. For larger orders (10kg, 25kg or more), the product is packed in drums or cartons with two-layer plastic bag inner protection to ensure product safety during transit.
Q
What shipping methods and delivery times are available?
We offer flexible shipping options based on order size. Small orders (1–25kg) are shipped via EMS, DHL, UPS, or FedEx with door-to-door delivery in 3–7 days. Larger shipments (25–100kg) go by DHL, FedEx, or air freight. Orders over 100kg can be shipped by air (3–7 days, door to airport) or by sea (10–35 days, door to port).
