Chemical Information
FooDB NameLysozyme
DescriptionPreservative. Prevents late blowing in semi-hard cheeses due to Clostridium tyrobutyricum Lysozyme is part of the innate immune system. Children fed infant formula lack lysozyme in their diet and have three times the rate of diarrheal disease.[citation needed] Since lysozyme is a natural form of protection from pathogens like Salmonella, E.coli and Pseudomonas, when it is deficient due to infant formula feeding, can lead to increased incidence of disease.; Whereas the skin is a protective barrier due to its dryness and acidity, the conjunctiva (membrane covering the eye) is instead protected by secreted enzymes, mainly lysozyme and defensin. However, when these protective barriers fail, conjunctivitis results. Lysozyme is found in garden onion, papaya, and soft-necked garlic.
