Lysozyme is a glycoside hydrolase composed of 18 kinds of 129 amino acid residues, with 4 S-S bonds and a molecular weight of 14,307. It is a hydrolase specifically acting on the cell walls of microorganisms and is also known as cell wall lysozyme. The specificity of the substrates acted upon by lysozyme is very strong, and the substrates acted upon by lysozyme from different sources are not the same. Lysozyme is widely present in various tissues and secretions of humans and animals, as well as in certain plants and microorganisms. It can dissolve the cell walls of Gram-positive bacteria and has a strong killing effect on them. It has broad prospects in food preservation (especially in the production of cheese and sake), medicine (tablets, capsules, eye drops, throat lozenges), and scientific research.
Lysozyme has inhibitory and killing effects on both Gram-positive and Gram-negative bacteria, and the antibacterial effect is obvious. This product has no effect on yeast and can be used for yeast recovery and expansion in beer production, as well as in the early stage of fermentation to prevent contamination by miscellaneous bacteria.
Application in medicine: It is mainly used for various mucosal inflammations in otorhinolaryngology, such as paranasal sinusitis, chronic rhinitis, acute and chronic pharyngitis, lichenus planus, oral ulcers, exudative otitis media, as well as in dermatology, such as herpes zoster, flat warts, chickenpox, etc. It is also used for asthmatic tracheitis, ulcerative colitis, mumps, etc. This product works better when used in combination with antibacterial drugs. Application in biotechnology: Lysozyme has the function of destroying the structure of bacterial cell walls. Treating G+ bacteria with lysozyme can yield protoplasts after destroying the cell walls, so it is widely used in biotechnology and has become an indispensable tool enzyme for cell fusion operations in genetic engineering and cell engineering. Application in aquatic products and meat products: Considering the non-toxic and harmless characteristics of lysozyme and its decomposition effect on G+ cell walls, when applied to aquatic products and meat products, Chemicalbook can play a role in preservation and anti-corrosion for aquatic products and meat products while ensuring that the original nutrients of the food are not lost. The combined application of lysozyme with sodium chloride and nitrite can extend the shelf life of meat products, and its preservative effect is better than that when used alone. When 0.05% lysozyme is used in combination with phytic acid polyphosphate, glycine and other substances as a preservative and freshness preservation agent, it can extend the storage period of seafood and aquatic products. Application in other foods: Cream cakes are one of the foods prone to spoilage and deterioration. Adding lysozyme to pastries can prevent spoilage and deterioration caused by microorganisms. The application of lysozyme in food preservation also has an extremely obvious effect. At the same time, due to the fact that lysozyme is non-toxic, harmless and has health benefits, such as anti-infection and enhancing the efficacy of antibiotics, as well as promoting blood coagulation, hemostasis and tissue regeneration, some people are now attempting to use it as an additive in food to enhance its health benefits.
Danger
Swallowing is harmful (H302) and may irritate the respiratory tract and skin
It may polymerize at high temperatures, so contact with peroxides, strong acids/bases should be avoided
