Lysozyme Powder Specifications

For customers with specific processing or quality requirements, please contact us with your intended application and target specification. We can provide current product documentation for technical review.

What Is Lysozyme Powder?

Lysozyme is a naturally occurring glycoside hydrolase found in a variety of animal tissues and secretions. Hen egg-white lysozyme, one of the best-characterized forms, consists of 129 amino acid residues with four disulfide bonds and has a molecular weight of approximately 14.3 kDa.

The main industrial interest in hen egg white lysozyme comes from its ability to hydrolyze structural components of bacterial cell walls. This makes the enzyme useful in applications where microbial control or bacterial cell-wall disruption is required.

Our lysozyme enzyme powder is supplied as a water-soluble white to light-yellow powder. Depending on the intended market and application, food-grade and pharmaceutical-grade material is available. Because application requirements vary between industries and countries, customers should evaluate the appropriate grade, dosage and regulatory status for their finished product before commercial use.

How Does Lysozyme Work?

The antimicrobial action of lysozyme enzyme is based on enzymatic hydrolysis of peptidoglycan, an important structural component of bacterial cell walls.

More specifically, lysozyme hydrolyzes the β-1,4 glycosidic linkage between N-acetylmuramic acid (NAM) and N-acetylglucosamine (NAG). Breaking these bonds weakens the peptidoglycan network that provides structural integrity to the bacterial cell wall, which can eventually result in cell-wall damage and lysis.

Lysozyme and Gram-Positive Bacteria

Lysozyme generally shows stronger direct activity against Gram-positive bacteria because their thick peptidoglycan layer is comparatively accessible to the enzyme. This is one reason lysozyme antimicrobial enzyme preparations have attracted long-standing interest for microbial control in food and biotechnology applications.

Gram-negative bacteria also contain peptidoglycan, but it is located behind an outer membrane. This additional barrier can limit direct access of lysozyme to its substrate, so practical effectiveness depends on the microorganism, formulation and processing conditions.

Key Features of Our Lysozyme Powder

CHEN LANG BIO TECH supplies egg white lysozyme with an enzyme activity of 20,000 U/mg. The powder dissolves in water and remains comparatively stable under acidic conditions, making it suitable for a range of formulation and processing environments.

For industrial buyers, however, enzyme activity alone does not determine whether a material is suitable. Grade, processing conditions, pH, temperature, intended dosage and finished-product requirements all need to be considered together. We therefore recommend evaluating lysozyme according to the actual application rather than selecting it only by a specification number.

Food-grade and pharmaceutical-grade options are available for different manufacturing requirements.

What Is Lysozyme Powder Used For?

The combination of enzymatic activity and bacterial cell-wall hydrolysis gives lysozyme powder applications across food processing, dairy products, biotechnology and pharmaceutical manufacturing.

Lysozyme for Food Preservation

One of the established uses of food grade lysozyme powder is microbial control in food processing. As an enzyme with antimicrobial activity, lysozyme can be incorporated into suitable preservation systems to help control susceptible microorganisms and support product stability.

Potential applications include selected meat products, aquatic products, beverages, bakery products and fermented foods. The actual performance of lysozyme for food preservation depends on factors such as pH, temperature, food composition, target microorganism and dosage.

Lysozyme should therefore be regarded as a functional component of a preservation system rather than a universal replacement for all other preservation methods.

Lysozyme for Dairy and Cheese

Dairy processing is another important application area for food grade lysozyme. In suitable cheese and dairy processes, the enzyme can be used as part of microbial-control strategies where susceptible bacteria are a concern.

Customers sourcing lysozyme for cheese should consider the manufacturing process, target organisms, enzyme activity and local regulatory requirements before determining the final dosage. We can provide product specifications and samples for formulation and production trials.

Meat, Seafood and Beverage Applications

Lysozyme can also be evaluated for microbial control in meat products, seafood, beverages, sake and similar processed foods. Its effectiveness is influenced by the food matrix and processing environment, so dosage cannot be determined by enzyme activity alone.

For commercial projects, laboratory or pilot-scale testing is recommended before the formulation is transferred to full production.

Infant Food Applications

Lysozyme naturally occurs in human milk and has consequently been studied in relation to milk-based and infant nutrition applications. However, infant food and infant formula are highly regulated product categories.

Any proposed use of lysozyme food additive in these products should be assessed against the applicable regulations, allergen requirements and permitted conditions of use in the destination market.

Lysozyme for Biotechnology

Outside food processing, muramidase powder is useful in biotechnology because of its ability to disrupt bacterial cell walls. It is commonly associated with bacterial cell lysis, protoplast preparation and laboratory or industrial processes involving Gram-positive microorganisms.

Its specific action on peptidoglycan makes lysozyme for biotechnology particularly useful where controlled cell-wall disruption is required.

How to Choose Lysozyme Powder for Your Application

When sourcing bulk lysozyme powder, start with the intended application. A food manufacturer using lysozyme in cheese production has different technical and regulatory considerations from a biotechnology company using the enzyme for bacterial cell-wall disruption.

Enzyme activity is another important parameter. Our standard activity is 20,000 U/mg, but the effective addition level in a finished formulation depends on the process rather than on a fixed universal dosage.

Buyers should also review grade requirements, allergen considerations, processing temperature, pH and applicable regulations. For new projects, we recommend checking the specification and COA first and then conducting a sample trial under actual processing conditions before moving to a commercial batch.

Lysozyme Powder Quality Control

As an enzyme raw material, lysozyme requires more than a visual inspection before release. Batch evaluation is based on the applicable product specification, with enzyme activity being one of the key quality parameters.

Relevant quality items may include appearance, identification, enzyme activity and other physicochemical or microbiological parameters required by the applicable specification.

CHEN LANG BIO TECH can provide the current specification and lysozyme powder COA for customer evaluation. For buyers qualifying a new raw material supplier, we recommend reviewing the latest batch documentation rather than relying solely on general information published online.

Safety and Handling

Lysozyme is a protein enzyme, and concentrated enzyme powders should be handled carefully in an industrial environment. Direct inhalation of airborne powder or droplets should be avoided, particularly during weighing, transfer and formulation.

Appropriate protective equipment, including a mask, protective eyewear and gloves, is recommended when handling concentrated material. Spilled powder should be collected carefully while minimizing dust formation.

Lysozyme activity may also be inhibited or damaged by certain heavy-metal ions and oxidizing agents. Contact with substances such as Fe³⁺, Cu²⁺, Hg⁺ and Pb⁺ should therefore be avoided during storage and processing.

Because our product is derived from hen egg white, customers should also consider egg allergen requirements when evaluating it for food or other relevant applications.

Packaging and Storage

Our standard packaging for bulk lysozyme powder is:

•0.5 kg × 10 bags/carton

•0.5 kg × 20 bags/carton

The material should be kept tightly sealed in a cool, dry environment away from direct light. Storage below 0°C is recommended to help maintain enzyme activity.

Extended storage or unsuitable conditions, particularly excessive temperature and humidity, can reduce enzyme activity. Once opened, the material should be resealed promptly and protected from moisture and contamination.
