Products Description of Lysozyme CAS#12650-88-3
Lysozyme is a natural antimicrobial enzyme derived mainly from chicken egg white, appearing as a white to off-white powder or lyophilized powder. With a molecular weight of approximately 14.3 kDa, it specifically hydrolyzes the beta-1,4 glycosidic bonds in bacterial cell wall peptidoglycan, causing cell lysis and effective inhibition of Gram-positive bacteria. The product dissolves readily in water and maintains good stability under acidic conditions.
Owing to its natural origin and safe profile, lysozyme is widely used as a preservative in dairy, meat and seafood products, as well as an active ingredient in pharmaceutical and feed applications. It should be stored in a tightly sealed, dry and cool place, protected from light and moisture to preserve enzymatic activity.

Product Application of Lysozyme CAS#12650-88-3
Lysozyme serves as a natural and safe antimicrobial agent across multiple industries.
In the food sector, it is widely applied as a preservative in cheese, dairy products, meat, seafood and beverages, effectively extending shelf life by inhibiting spoilage bacteria without compromising flavor. In the pharmaceutical field, it is used in oral care products, throat lozenges and anti-inflammatory formulations to control bacterial infections and support mucosal health. As a feed additive, it helps reduce the use of antibiotic growth promoters in livestock and poultry farming. Moreover, lysozyme plays an important role in biotechnology for cell wall disruption and nucleic acid extraction, and is increasingly incorporated into cosmetics for its mild antibacterial and skin-conditioning benefits, meeting the growing demand for natural preservative solutions.
