What Is Lysozyme Powder?
Lysozyme is a natural alkaline enzyme. It widely exists in various tissues and secretions of humans and animals, as well as some plants and microorganisms, such as egg whites, saliva, and tears. It selectively targets Gram-positive bacteria while having minimal impact on most other microorganisms. Many industries utilize this feature to control unwanted bacterial proliferation.
Lysozyme kills bacteria by dissolving cell walls. It directly hydrolyzes β-1,4-glycosidic bonds in peptidoglycan. In this way, it destroys the structure of bacteria. Then water enters the bacteria, causing the bacterial cells to lyse.
Applications of Our Lysozyme Powder
During hard and semi-hard cheese production, lysozyme is used to inhibit the germination of Clostridium tyrobutyricum. This type of bacteria can ferment butyric acid and generate carbon dioxide gas. This can cause cracks and structural defects known as late blowing, reducing the value of the cheese.
Sunjoy produces lysozyme powder that can selectively eliminate these unwanted bacteria without affecting the lactic acid needed for your cheese fermentation.
During the fermentation and aging of wine and beer, the overgrowth of certain lactic acid bacteria (such as Lactobacillus and Leuconostoc) causes spoilage, acidity, and turbidity. Lysozyme can inhibit the Gram-positive spoilage bacteria without affecting the activity of Saccharomyces cerevisiae.
If you apply lysozyme powder to your wine and beer production, it will make your beverage stable and will not disrupt alcoholic fermentation. It also reduces the usage of sulfur dioxide.
Sunjoy lysozyme powder is formulated into lozenges for treating acute pharyngitis, chronic laryngitis, and aphthous ulcers. As an active ingredient, it directly contacts the mucosa and causes bacterial lysis. In this way, it alleviates local inflammation and edema.
Lysozyme powder is commonly applied to eye drops for treating bacterial conjunctivitis, blepharitis, and ocular infections caused by wearing contact lenses.
Lysozyme is also applied in ointments or creams for dermatology patients. These medications treat bacterial skin infections, herpes zoster, and provide antibacterial support for minor burns.
Acne vulgaris is related to the overgrowth of Cutibacterium acnes on the skin. Lysozyme can hydrolyze bacterial cell walls and help reduce bacterial burden on the skin. Compared to chemical ingredients such as salicylic acid or benzoyl peroxide, lysozyme does not damage the skin barrier or cause skin peeling and dryness.
You can highlight it as a key ingredient in your skincare products.
These days, organic and natural ingredients have become a trend in premium cosmetics products. Lysozyme is applied to replace traditional chemical ingredients such as parabens or phenoxyethanol. It can control the bacterial proliferation after opening the product and maintain biological stability.
You can use Sunjoy lysozyme powder in your skincare products and target the premium consumer group and the sensitive skin market.
Sunjoy lysozyme powder is used in animal feeding. It hydrolyzes harmful Gram-positive bacteria (such as Clostridium perfringens) without significantly affecting beneficial intestinal microorganisms. This allows it to reduce diarrhea rates and improve nutrient digestion in the animals.
You can blend our lysozyme powder in animal feed for weaned piglets, broilers, or shrimp. It will maintain the intestinal microecological balance of your animals and leave no drug residue in meat, eggs, or milk.
Lysozyme powder is a standardised tool to break down bacterial cells in the laboratory. It efficiently opens the tough outer layer of bacteria and releases the genes (DNA/RNA) and proteins inside. Compared with solely mechanical disruption methods, lysozyme treatment can reduce physical stress on biological samples.

Lysozyme is most effective for Gram-positive bacteria. The cell wall of this group of bacteria, such as Bacillus subtilis and Staphylococcus aureus, mainly consists of peptidoglycan up to 90%. Lysozyme can directly hydrolyze this peptidoglycan and cause bacterial lysis.
Gram-negative bacteria have an outer layer of lipopolysaccharide membrane that protects them from being dissolved by lysozyme. Therefore, lysozyme is much less effective against them.
In most cases, it is safe to use lysozyme orally or topically. But there are still some side effects. The most common type is allergic reactions. Sunjoy lysozyme powder is sourced from hen egg white. For people allergic to eggs, lysozyme may cause skin rash, hives, and potentially dyspnea in severe cases. In medical use, some patients may have slight gastrointestinal discomfort, such as nausea and stomach upset.
In pharmaceutical classification, lysozyme is in the category of non-antibiotic antibacterial and anti-inflammatory drug. It is also a type of therapeutic enzyme. Different from traditional chemical antibiotics, it is a natural protein that breaks down bacterial cell walls. Therefore, it is not associated with the development of conventional antibiotic resistance.
