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.
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 muramidase. It is primarily sourced from hen egg white, which contains approximately 3.4%–3.5% lysozyme as a proportion of total protein. It can also be produced through bioengineering processes.
Q
What are the main applications of lysozyme powder?
Lysozyme powder is widely used as a natural food preservative, a pharmaceutical ingredient in lozenges for treating pharyngitis and oral ulcers, and as a natural anti-infective agent. It provides antibacterial, antiviral, hemostatic, anti-swelling, and analgesic effects, and also promotes tissue repair.
Q
What is the enzyme activity level of your lysozyme powder?
Our lysozyme powder has a minimum activity of 2,000 U/mg, with tested results reaching 2,300 U/mg. For pharmaceutical-grade applications, activity exceeds 20,000 U/mg when produced through bioengineering with pH adjustment and ion-exchange resin purification.
Q
How should lysozyme powder be stored to maintain its activity?
Lysozyme powder should be stored in a cool, dry place away from direct light, with a recommended storage temperature below 0°C. Humidity should be kept below 60% RH. Improper storage conditions such as high temperature or humidity may cause a decrease in enzyme activity, in which case an increase in dosage during application is advised.
Q
What packing options are available and how is the product shipped?
For 1kg orders, the product is packed in a double plastic bag with an aluminum foil bag inside, placed in an outer box. For 10kg, 25kg, or larger quantities, drums or cartons with two layers of plastic bags inside are used. Shipping is available via EMS, DHL, UPS, FedEx (for 1–25kg), by air or sea for larger volumes, with delivery times ranging from 3–7 days (air) to 10–35 days (sea).
Q
Is lysozyme powder safe for use in food and pharmaceutical products?
Yes, lysozyme powder is a non-toxic protein with no known side effects at recommended usage levels. It has been widely accepted as a safe natural preservative and pharmaceutical ingredient. Our product passes strict microbiological testing, including zero detection of E. coli and Salmonella, and meets heavy metal safety standards (Pb and As both <2.0 mg/kg).
