Product Description

Product Description
lysozyme 1
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 (FAQ)
Q What is lysozyme powder and where does it come from?
Lysozyme powder is a natural hydrolysis enzyme that targets microbial cell walls, also known as a cell wall dissolving enzyme. It is widely found in nature, with hen egg white being the most representative and well-studied source, accounting 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 anti-infective agent, and in healthcare products such as lozenges for acute and chronic pharyngitis and oral ulcers. It also provides antibacterial, antiviral, hemostatic, anti-swelling, and analgesic effects, and supports tissue repair.
Q What is the enzyme activity level of your lysozyme powder?
Our lysozyme powder has a minimum enzyme activity of 2,000 U/mg, with actual tested results reaching 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?
Lysozyme powder should be stored in a cool, dry place away from light, at a recommended temperature below 0°C. Humidity should be kept below 60% RH. If stored under high temperature or humidity conditions, enzyme activity may decrease and an increased dosage during application may be necessary.
Q What packaging options are available for lysozyme powder?
For 1kg quantities, the product is packed in a bag with a double plastic bag and aluminum foil bag inside, placed in an outer box. For 10kg, 25kg, or larger orders, drums or cartons with two layers of plastic bag inside are used to ensure product integrity during shipping.
