⭐ Product Features
1As a natural preservative, lysozyme is stable over a range of pH values.
2It lyses bacterial cells, especially Gram‑positive bacteria, and exhibits key antibiotic properties.
3Produced 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 that hydrolyzes microbial cell walls, also known as a cell-wall dissolving enzyme. It is primarily sourced from hen egg white, where it accounts for approximately 3.4%–3.5% of total protein content, and is one of the most well-characterized lytic enzymes in nature.
Q
What are the main applications of lysozyme in food and medicine?
Lysozyme is widely used as a natural food preservative due to its non-toxic, bacteriolytic properties. In medicine, it serves as a natural anti-infective agent offering antibacterial, antiviral, hemostatic, anti-swelling, and analgesic effects. It also accelerates tissue repair and is found in lysozyme lozenges for treating pharyngitis and oral ulcers.
Q
What is the enzyme activity level of your lysozyme powder?
Our lysozyme powder meets pharmaceutical-grade standards with an enzyme activity exceeding 20,000 U/mg as produced. The Certificate of Analysis shows a tested result of 2,300 U/mg against a minimum requirement of 2,000 U/mg, confirming consistent quality and potency.
Q
How should lysozyme powder be stored to maintain its activity?
Lysozyme powder should be stored in a cool, dry place away from light, at a temperature below 0°C. It should be kept at relative humidity below 60%. If stored under high temperature or humidity conditions, enzyme activity may decrease and an appropriate increase in dosage during application is recommended.
Q
What packaging options are available for lysozyme powder?
For small quantities (1kg), lysozyme is packed in a double plastic bag with an aluminum foil bag inside, placed in an outer box. For larger quantities (10kg, 25kg, or more), it is packed in drums or cartons with 2 layers of plastic bag inside to ensure product integrity during transport.
Q
What shipping methods are available and how long does delivery take?
For 1kg–25kgs, we ship via EMS, DHL, UPS, or FedEx with door-to-door delivery in 3–7 days. For 25kg–100kgs, we use DHL, FedEx, or air freight in 3–7 days. For orders over 100kgs, air freight (3–7 days, door to airport) or sea freight (10–35 days, door to port) is available.
