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 dissolution enzyme. It is widely distributed in nature, with a particularly rich source in hen egg white, where it accounts for approximately 3.4%–3.5% of total egg white protein.
Q What are the main applications of lysozyme powder?
Lysozyme powder is used as a natural food preservative, a pharmaceutical ingredient in lozenges for pharyngitis and oral ulcers, and as a natural anti-infective agent. It provides antibacterial, antiviral, hemostatic, anti-swelling, and analgesic effects while accelerating tissue repair.
Q What is the enzyme activity level of your lysozyme product?
Our lysozyme powder has a minimum enzyme activity of 2,000 U/mg, with our tested batch achieving 2,300 U/mg. Products produced via bioengineering and ion-exchange resin purification can exceed 20,000 U/mg, meeting pharmaceutical-grade standards.
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, ideally at a temperature below 0°C. It should be kept in a humidity-protected environment with relative humidity below 60%. If stored under unfavorable conditions, enzyme activity may decrease and a dosage adjustment may be required.
Q What packaging options are available for lysozyme powder?
For 1 kg orders, the product is packed in a double plastic bag plus aluminum foil bag inside a box. For larger quantities of 10 kg, 25 kg or more, it is packed in drums or cartons with two layers of plastic bags inside to ensure quality preservation during transit.
