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.
🛡️
Natural Preservative
Lysozyme is stable over a range of pH values, making it an effective natural preservative.
🔬
Antibacterial Action
It lyses bacterial cells, especially Gram‑positive bacteria, and exhibits key antibiotic properties.
⚗️
Pharmaceutical-Grade Purity
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 where does it come 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, with hen egg white being the most well-known and richest source, comprising approximately 3.4%–3.5% of total egg white protein.
Q
What are the main applications of lysozyme?
Lysozyme is used as a natural food preservative, a pharmaceutical anti-infective agent, and in medical lozenges for treating acute and chronic pharyngitis and oral ulcers. It provides antibacterial, antiviral, hemostatic, anti-swelling, and analgesic effects while also accelerating tissue repair.
Q
What is the enzyme activity of your lysozyme powder?
Our lysozyme powder has a minimum enzyme activity requirement of 2,000 U/mg, with our tested result reaching 2,300 U/mg. The production process involves bioengineering, pH adjustment, and ion-exchange resin purification, achieving activity exceeding 20,000 U/mg for pharmaceutical-grade products.
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 storage temperature below 0°C and relative humidity below 60%. Enzyme activity may decrease if stored for too long or under unfavorable conditions; if temperature or humidity is too high, increasing the dosage during application is recommended.
Q
What packaging options are available for lysozyme powder?
For 1kg quantities, lysozyme is packed in a double plastic bag with an aluminum foil inner bag, placed in an outer box. For 10kg, 25kg, or larger orders, packaging is available in drums or cartons with two layers of inner plastic bags to ensure product integrity during transport.
Q
What shipping methods and delivery times are available?
For orders of 1kg–25kg, we ship via EMS, DHL, UPS, or FedEx with door-to-door delivery in 3–7 days. Orders of 25kg–100kg ship via DHL, FedEx, or air freight in 3–7 days. For orders over 100kg, air freight (3–7 days, door to airport) or sea freight (10–35 days, door to port) is available.
