HIGH QUALITY Food grade lysozyme
PRODUCT DESCRIPTION
food enzyme Lysozyme, also known as Muramidase or N-acetylmuramide glycoanhydrase, is an enzyme capable of hydrolyzing mucopolysaccharide in pathogenic bacteria. In nature, lysozyme is commonly found in the egg white of birds and poultry and in tears, saliva, blood, snot, urine, milk and tissue cells of mammals (such as liver, kidney, lymphoid tissue, intestine, etc.), and can also be isolated from plants (such as papaya, turnip, barley, figs, cabbage, radish, etc.).
Dairy Enzyme Lysozyme has a wide antibacterial spectrum, it has effect on Gram-positive bacteria and Gram-negative bacteria, it even works on some viruses, and it is safe and non-toxic to human body, with no unwanted effects. Therefore, the enzyme has found wide applications in food, feed, medicine and other fields.
MECHANISM
As a bactericide, lysozyme is a glycoside hydrolase attacking β - 1,4 glycoside bond between n-acetyl-cell-wall acid (NAM) and N-acetylglucosamine (NAC). By degrading peptidoglycan into glycopeptide, the insoluble mucopolysaccharide gets solubilized, which leads to disintegration of bacterial cell wall and leakage of cell content, and the bacteria are thus killed.
As antivirus agent: lysozyme can bind negatively charged virus protein to form complex salts with DNA, RNA and apocofactor protein, which inactivates the virus. In addition, lysozyme is able to activate the immune system of body and modulate the cytotoxic mechanism mediated by lymphocytes and macrophages to kill the virus.

APPLICATIONS
l Dairy enzyme products: Incorporate into baby food or formula milk powder as a non-specific immunological factor to kill Enterococcus putrefaciens bacteria.
l Cheese: Add during cheese production to prevent butyric acid fermentation due to microbial infection; avoid foaming during cheese production at later stage.
l Use as fresh-keeping agent for aquatic products, meat products and fruits: Spray onto aquatic products or meat to prevent spoilage.
l Cake and beverage: Prevent microbial growth especially on those cakes containing cream.
