Lysozyme powder plays a special role as a microbial cell wall hydrolysis enzyme, also referred to as a cell wall dissolving enzyme. Widely distributed in nature, including egg white where lysozyme accounts for 3.4% - 3.5% of the total protein, it serves as a typical representative of lytic enzymes and one of the most thoroughly understood lysozymes.
🔬 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 protein with no side effects and exhibits strong bacteriolytic effects, making it ideal for use 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 commonly used for acute and chronic pharyngitis, oral ulcers and related conditions.

Frequently Asked Questions (FAQ)
Q
What is lysozyme powder and what is it derived from?
Lysozyme powder is a natural enzyme that hydrolyzes microbial cell walls, also known as a cell wall dissolving enzyme. It is widely distributed in nature, and the most common commercial source is hen egg white, where lysozyme accounts for approximately 3.4%–3.5% of total protein.
Q
What are the main functions of lysozyme in food and pharmaceutical applications?
Lysozyme functions as a natural preservative and anti-infective agent. It remains stable across a range of pH values, effectively lyses Gram-positive bacteria, and provides antibacterial, antiviral, hemostatic, anti-swelling, and analgesic benefits. It also accelerates tissue repair and is widely used in lozenges for pharyngitis and oral ulcers.
Q
What is the enzyme activity level of your lysozyme product?
Our lysozyme powder is produced via bioengineering with precise pH adjustment and ion-exchange resin purification. The enzyme activity exceeds 20,000 U/mg, fully meeting pharmaceutical-grade standards, with certified test results confirming high purity and performance.
Q
How should lysozyme powder be stored to maintain maximum activity?
Lysozyme powder should be stored in a cool, dry place away from direct light, with a recommended storage temperature below 0°C. It must be kept at a relative humidity below 60%. Proper storage ensures a shelf life of up to 2 years.
Q
What packaging options are available for shipping?
For 1 kg orders, the product is packaged in double plastic bags with an aluminum foil bag inside a protective box. For quantities of 10 kg, 25 kg, or more, robust drums or cartons with double-layer plastic bags inside are used to ensure maximum safety during transit.
Q
What shipping methods and delivery times can I expect?
For small orders (1–25 kg), we ship via EMS, DHL, UPS, or FedEx with door-to-door delivery in 3–7 days. For 25–100 kg, air freight or express carriers are utilized. For bulk orders exceeding 100 kg, flexible air freight or sea freight options are available depending on your destination requirements.
