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
What is lysozyme powder and where does it come from?
Lysozyme powder is a hydrolysis enzyme that targets microbial cell walls, also known as a cell-wall dissolving enzyme. It is widely found in nature, with egg white being its most representative source — lysozyme accounts for approximately 3.4%–3.5% of total egg white protein.
What is the enzyme activity level of this lysozyme powder?
This lysozyme powder is produced through bioengineering, pH adjustment, and ion-exchange resin purification. Its enzyme activity exceeds 20,000 U/mg, meeting pharmaceutical-grade standards. The COA shows a tested result of 2,300 U/mg against a minimum requirement of 2,000 U/mg.
What are the main applications of lysozyme powder?
Lysozyme is used as a natural food preservative, a pharmaceutical anti-infective agent, and in medical lozenges for acute and chronic pharyngitis and oral ulcers. It provides antibacterial, antiviral, hemostatic, anti-swelling, and analgesic effects while accelerating tissue repair.
How should lysozyme powder be stored to maintain its activity?
It should be stored in a cool, dry place away from light, ideally at temperatures below 0°C. Relative humidity should remain below 60%. Enzyme activity may decrease under high temperature or humidity, so an appropriate dosage adjustment may be needed in such conditions. Shelf life is 2 years when properly stored.
What packing options are available for lysozyme powder?
For 1 kg orders, it is packed in a double plastic bag with an aluminum foil bag inside, placed in an outer box. For 10 kg, 25 kg, or larger quantities, it is packed in drums or cartons with 2 layers of plastic bags inside to ensure protection during transport.
What delivery methods and timeframes are available?
For small orders (1–25 kg), EMS, DHL, UPS, and FedEx are available with delivery in 3–7 days door to door. For 25–100 kg, air freight via DHL or FedEx takes 3–7 days. For orders over 100 kg, air freight (3–7 days, door to airport) or sea freight (10–35 days, door to port) is available.
