Applications
Lysozyme is a natural antimicrobial enzyme that helps inhibit susceptible bacteria, supporting process stability and extended shelf life. It is widely used in dairy, beverages, meat/seafood preservation, and oral care products.
Cheese Preservation
Natural antimicrobial in cheese—helps prevent late blowing caused by Clostridium tyrobutyricum in Gouda, Edam, and other hard cheeses.
Wine — Malolactic Control
Controls lactic acid bacteria in wine as an alternative to sulfites, supporting microbial management in EU and many wine-producing countries.
Meat & Sausage Preservation
Natural preservative for processed meats—extends shelf life by inhibiting Gram-positive spoilage bacteria.
Pharmaceutical — Immune Support
Used as an active ingredient in throat lozenges and oral care products for antimicrobial activity against oral pathogens.
Seafood Preservation
Surface treatment for fresh fish and shrimp—delays microbial spoilage and helps extend refrigerated shelf life.
Active Packaging
Incorporated into edible films and coatings for active food packaging—forms an antimicrobial barrier on cheese and meat surfaces.
